Help me get ready for CCNA Grinding!

Question: Help me get ready for CCNA Grinding!

Hey everyone,

I am 25 and am in Phoenix, AZ. I am currently pursuing my CCNA to start my networking career and am seeking some guidance. My experience and knowledge thus far is pretty fragmented, I know a little about a lot PC hardware/software/networking/virtulization/data storage/VOIP/security.

I currently work as a technical support agent providing Tier 1 VOIP support for a small company here in Phoenix. We support about 11 different VOIP providers and we provide their Tier 1 support, I support all of these clients in many aspects, from moves/add/changes all the way up to troubleshooting their Cisco/Adtran/Edgemarc devices and calling carriers for T1 circuit issues. I have a lot of experience with Polycom and Cisco phones, so I'd like to move into my CCNA Voice at some point.

I feel that after I achieve my CCNA, I'd like to get started on some VMWare/HyperV certification as thats where my curiosity is.

I have enrolled with IT University Online, they had a deal on Groupon for $100 which included the following courses.

640-822 Cisco ICND1 CCENT
640-816 Cisco ICND2 - CCNA
640-461 ICOMM v8.0
640-553 IINS
640-554 IINS

I've got until 11/17/13 before all of it expires and I'd like to get as much done as possible. Has anyone had any experience with IT University Online? Do you think it's of good quality and sufficient for my needs?

I've also decided that GNS3 will not be sufficient enough for me and I would benefit from having some physical hardware to play with. I have been looking around on eBay for CCNA Lab Kits and I am pretty lost as to what I need and what I should get. I am hoping to not spend anymore then $300 or so on a CCNA Lab Kit. Can anyone provide some guidance here as to how many routers/switches I should get and what models? What tools do I need? I've got puTTY and Wireshark already.

I am also facing some motivation problems, honestly I couldn't care less about networking or Cisco for that matter, but I do not want to get a 4 year degree at a college and feel that getting a CCNA would be a great way to start to my career.

How do you guys stay motivated to learn this stuff and what keeps you going?

Thanks for any help or feedback!

Preferred Solution: Help me get ready for CCNA Grinding!

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

Ok, can anyone explain the difference between these two books?

If I'm starting in on learning Cisco CCNA Which one of these do i want? Or do i want both?

Right, got a brand new pc 2 weeks ago. Been really lovely to me so far, apart from the HDD grinding..
I've looked through the whole interwebs and a bit more but none on the solutions has helped me! I've disabled Super fetch and Windows search which helped a little. But i still hear grinding from my harddrive? is it just my case (ive removed the harddrive screws)?
I've been looking into the Reliabilty and Performance monitor and it looks like Svchost.exe is causing the problems.
Trying to get screenshots of it (in the reli and perfor montior) but for some reason its being quite quiet! Bah!

As in title, is it safe to assume that a usb 3.0 flash drive is Ready Boost ready? I'm not finding any that actually say they are. This question assumes that the device will be plugged into a 3.0 port.

Answer:Is it safe to assume that a usb 3.0 flash drive is Ready Boost ready?

I plugged my SanDisk 32GB USB 3.0 Thumb drive [noted by the blue insert] into my front USB 3.0 port, right-clicked the icon in File Explorer, click Properties then clicked the ReadyBoost tab, see that I can use it for ReadyBoost up to 4094MB or about 4GB. I could make the size less but not more. Where I'd see more use would be on Notebooks with the SDHC card port and 4GB or less physical RAM, mainly because the SDHC card doesn't protrude very far and less damage if bumped. Same for card readers on Desktops.

I am running with Vista Starter SP1, and it happened that my USB is compatible with the Ready Boost so I can use it excellent.
Now, remember the option saying that "Use this device" and "Do not use this device"? I can remember that checking the "Use.." when I opt to use the feature, and it works.
The problem is that I wanted to disable this Ready Boost because I am going to use my USB now. When I click Properties>General, it says that the total memory I have is 1.87 GB, 1.86 of it is in use (and I guess it's for Ready Boost). When I navigate through Ready Boost tab (in case checking "Do not use..."), there are no options available! And the only thing it says (image is in here ) is that I need about 235 MB to start Ready Boost. I get surprised, because about 1.86 GB is already used for Ready Boost, yet there is no option for disabling it?

There are no files in the USB, except this cache file containing the Boost. I suspect that the system doesn't recognize the existence of the earlier boost, and thinks that it is only another file.

I tried to do the following:
1. Reformatting the drive
2. Manually deleting the cache
3. Deleting the cache using administrative command prompt
4. Stopping Ready Boost service in services.msc

But to no avail. It reformatting and deleting always give me the result that the disk is write-protected. Even utilizing the remaining 12 MB doesn't work, it always say that it cannot be performed because the di... Read more

Are you fully updated at SP1?

You should then load the memory stick & sort it out!

OK not serious but at the moment my hard drive will not shut up, constant CPU usage between 3 and 6 percent accessing something. All I can see in the task manager is a little bit of avg and some system tasks. Im at a dead loss on this.

Answer:Serious grinding!

C:\Program Files\Java\jre6\bin\jqs.exe, the Java Quick Starter service can cause unnecessary disk access. Unless you use a lot of Java applications and want them to start as fast as possible, open services.msc (Start->Run->services.msc) and change its startup type to manual. This is a particularly annoying service and will re-enable itself everytime you update the Java Runtime Environment.

I'd also disable the Java Update Scheduler (C:\Program Files\Java\jre6\bin\jusched.exe) and the installshield update service (C:\Program Files\Common Files\InstallShield\UpdateService\issch.exe) but then I prefer to take manual control of my updates rather than letting them happen automatically.

Question: T61 grinding fan

I have a T61 7658 CTO, and the fan has been making more and more noise as time has gone by.  It started as a light clicking while the fan is running, and now it makes a fairly loud grinding noise.  I'm well out of warranty, so that's not an option.  Does anyone know if there's a way I can fix this, or do I need to replace the fan?  If I do need to replace the fan, any idea where I can get one?

Answer:T61 grinding fan

Bearing on the fan is properly running out of lubrication. Someone say, if you pull on the fan itself, it should pop off, which allows you add some high quality bearing oil/grease. I never tried this myself, so i don't know whether this will actually works.  If worst comes to worst, just replace the fan yourself, you can source one from ebay for around 70 to 100 USD.  Message Edited by lead_org on 04-05-2009 07:54 PM

Hello everyone, I just bought an S10 because of how good quailty Lenovos are claimed to be. I, however am having a problem with my newly bought IdeaPad S10 4333-22u. As soon as I turned my Lenovo on and it booted to Windows I noticed the fan came on and was buzzing/grinding. It mas making a noise as if the bearing in the fan were going bad or the core of the fan needed a few drops of oil. I am a PC Tech by trade and have encountered many failing fans so I am familiar with the sound they often make before siezing. After the Netbook ran a little while and heated up, the buzzing/grinding wasn't so loud, but definately present. You could hear the noise from quite a distance away. After searching the web, I found threads complaining of S10 fan noise, but the general idea I got from the forums was simply that the "whirring" noise of a normal operating fan was simply quite loud for a netbook when the S10's fan was at full RPM. My fan on the other hand, is clearly and quite audibly gridning. I don't believe this is what the users on these forums mean when they refer to the S10's noisy fan, correct? I really like this Netbook and would rather not return it, so I called Lenovo and they promptly sent an RMA Fed-Ex label so that I can send the unit to their service center for a heatsink/fan replacement. My question is, what does everyone mean when they say their S10 fan is loud? Can anyone describe it? Is it possible someone can record the noise their S10 makes and up... Read more

Question: Grinding Sound

Hello, I have a Lenovo Thinkpad T61 Laptop. When I work on the laptop, it suddenly start producing a grinding sound. It is coming form the Top-Left corner of the laptop. It is not coming all the time. It is not coming immediately when I turn it on. But if I use it for like 30 minutes, it will start producing the sound. It will produce this sound for the next 15 to 30 minutes and then gradually stop after that. This happens every day. Is it a heatsink+fan issue? How can I fix this ? Thanks. 

Answer:Grinding Sound

It sounds like your fan is failing. My fan has failed on my old Thinkpad x61 tablet. You can get the instructions here look at page 88, the steps are there. PM me if you need any help. If you replace your fan remember to get new thermal grease.

I am not a Mac guy, I have no idea what I am looking at.
I am at a remote location where there is no actual tech support of any kind. The Mac Book Pro of a colleague has been experiencing severe slow-downs over the past few days. Stuff doesn't highlight anymore, response is overall slow, the Internet connection speed is crawling.

My laptop (PC) works just fine when it's right next to his machine, there's no issue with the wireless infrastructure.

I am not even sure where to start looking. The user says that he didn't install anything weird as far as he can tell. and that it's been getting slower over the past few days. Any suggestions on where to even start looking for this problem?

Answer:OSX is grinding to a halt

Might consider asking an Admin/Mod to move this to the Apple forum as that's where almost all Apple/Mac/OSX support gets the attention. Yes, OSX is an operating system but, even so...

As for a suggestion, tell him to open the Utilities folder in Applications and then find Activity Monitor (should be the very first icon upper left as they're in alphabetical order) and run it a while to see what's going on. Look for processes that are consuming a lot of CPU time, or excessive RAM usage. It's not too different from Task Manager in some respects so you should be able to get some idea of what errant app or process could be dragging the machine's performance downward.

Answer:PC Slow/Grinding

If there is a grinding noise it's probably the harddrive or the fans. You can check this by opening the box and disconnecting the fans one by one and see if the noise still persists. If the noise is still there you can run a diagnostic on your hard drive. Run hard drive diagnostics: tacktech.comMake sure, you select tool, which is appropriate for the brand of your hard drive.Depending on the program, it'll create bootable floppy, or bootable CD.If downloaded file is of .iso type, use ImgBurn: imgburn to burn .iso file to a CD (select "Write image file to disc" option), and make the CD bootable.For Toshiba hard drives, see here:Note : If you do not know how to set your computer to boot from CD follow the steps here

Hi all, I'm based in Portugal and I've bought my Yoga 910 back in March. Despite all the well known problems with fan noise I've been able to stand it however during the last weeks my yoga has been developing a terrible grinding noise from one of the fans. The issue seems to be mechanical, as if the fan on the right of the keyboard is hitting the back part of some of the keys ("enter", "backspace" and surrounding keys) or eventually hitting some part of the metal casing. By pressing some parts of the casing it seems to decrease the noise but it always comes back. I've found a video on youtube that shows what is happening ( however in my case the problem only comes from one of the fans. If the common fan noise can be already disturbing this one is even more annoying. Would like to know if anyone had a similar issue and the best solution to have this sorted out. Thanks!

I bought a new WD 2TB HDD and during the format process there were two points where it made a buzzing noise for a few seconds (the rest of the process was completely silent as usual). Could it just be random or bad sectors? I really don't like a new drive that has bad sectors because it will probably deteriorate quickly.

Answer:Grinding while formatting new HDD

Noises like that are unusual. I'd run a hard drive test diagnostic on it. WD has tools available for testing drives last drive I had that was new that made a strange noise crashed about a week later. It was a 300GB Hard Drive that occasionally would make a loud ping noise followed by drive chatter then it would get silent. The event log for this archive data file server showed many warnings in yellow that the hard disk is about to fail with delayed writes etc. This drive also was very hot to the touch which as abnormal for the fact that everything else in the tower was cool to the touch and adequate airflow. I sent this drive back RMA and got a replacement 300GB that ran warm, but not as hot as the prior drive that failed. This replacement refurb drive lasted over 2 years without issues.

Hi there.

Recently I have noticed that whenever I run a graphically intensive program (such as a new-ish game), my framerate will decrease over a five minuite period.
Before this problem occured I could run the the same games perfectly smoothly.

I had a similar problem to this a few months back, in which I found that the large vent on the side of my computer was almost completely blocked. Cleaning the dust away from that vent returned my computer to normality.
However this time the vents on my computer are still clear, and opening up the computer revealed virtually dust-free innards.

Could this problem be related to over-heating like last time? I have no way to read the temperature of my computer (that I know of), it doesn't have an external thermometer.

I don't know if this'll be any help, but here is a screenshot of my CPU usage while running one of the aforementioned games running a rolling demo. The rolling demo loops around every 2 minutes. I did not touch the computer during this time. I've marked the time when FPS drops become very noticable (from ~30 to jumping between 5-20) with a red line.

On the same rolling demo, I took screencaps with the FPS counter showing every 30 seconds from starting the program.
These were the results:
Time - FPS
0:30 - 53
1:00 - 62
1:30 - 65

Question: Grinding noise?

Hello. I've been hearing a grinding noise for sometime on start-up on my PC. Occasionally, the PC will pretty much hang at the windows XP logo. When this occurs i just hold in on the power button and go through the boot process without any problems. However, the grinding noise that comes at the start is very loud and doesn't sound healthy at all. I've opened the case and there's no cords in the way of the fans. What could the noise be? Should i have concern? My computer runs fine after the noisy few seconds into the boot but becomes normal after it passes the windows XP logo.

First of all, let me say you need to back up this drive immediately unless you want to risk the chance of losing all your data. This drive might be ready to bite the dust, so get that done.

I would go to the drive manufacturer's website and download the drive utility and run it on this drive to see what might be the problem. You need to get tha done quickly while the drive is still operational.

Question: Grinding Noise

I have an Everex Explora, AMD Athlon computer and at the start up and when I am searching for info it makes a grinding noise while it is loading the information. Also twice last week after typing and searching for what I wanted I heard a loud grinding noise. Not knowing anything about computers I have no idea what is the problem. Any help would be appreciated.

Answer:Grinding Noise

Hi lag
Grinding noises aren't good. It sounds like you hard drive is going. I would back up your important data NOW. You can run a scandisk (surface scan) and defrag to help test out the hard drive. Many manufacturers of hard drive also have utilities on their web sites you can run to test out the drive. Is your system under warranty? Many hard drives come with a three year warranty.

Question: Grinding noise?

can someone please help me?
just a few minutes ago i was simply browsing and heard a loud grinding noise from my pc, i checked all the fans and it seems to be from the gpu, i restarted pc and still goes on. i left it off for now but i cant seem to find the cause, nothing is hitting anything

Answer:Grinding noise?

You wouldn't be able to see anything. The grinding noise occurs when the ball bearings go ( at one point the balls start showing wear and don't run "round" anymore, causing the fanblades to tumble.)
Simple solution: you need a new fan. In cases of emergency (like you can't get your hands on a new fan anytime soon) there is a way to prolong the life of the fan a little bit. You get some graphite powder from your automotive supplier, peel back the fan label and carefully put a little bit onto the center of the fan.
I really mean CAREFUL the stuff is worse on cloth than laser toner
Make sure to put the label back on and don't use any form of will only cause a mess.

The story so far....

Came home from a week abroad. Kids had been looking up game cheats (suspicious). System (HP desktop, 3 years old, upgraded from Vista to Win 7 Pro x32) was running slow and coming to a gradual freeze. Had been working just fine before I left town, and for the last few months since I upgraded.

I get home - system is now at the stage where it will boot to the login screen - I can login but immediately freezes once all the icons have loaded. I can boot in safe mode, manage to run AVG 9.0 scan, no problems found. I try a system restore - no joy - freezes after a while. The problem gets worse. Can no longer boot in safe mode, PC now gives me two options - boot normally or do system repair. Try the latter - it loads files, but then goes to a blank screen and hangs. If I attempt norml boot, I get to the windows 7 logo, but it just stays there for hours.

I do have recovery disks. Tried booting from them (after altering th eBIOS to boot from drive), again loads files,and get the loading bar, no logo this time, but then, again, no further progress.
I can get to the BIOS, F10 Setup and F11 System Recovery (which gives same result as above) - no option for safe mode anymore, just system repair/normal boot options. F8 doesn't get me anywhere.

I'm stumped - any ideas?

Answer:Win 7 Grinding Halt

It could be a hard-drive failure - have you tried running scandisk?
try scandisk /autofix
/autofix - This option will fix any errors it encounters without prompting you first. By default, when you use the /AUTOFIX option, ScanDisk will save any lost clusters it finds as files in the drive`s root directory. If you want ScanDisk to delete lost clusters instead of saving them, include the /NOSAVE option. Using the /AUTOFIX option, ScanDisk will also prompt you for an Undo disk unless you include the /NOSUMMARY option. The /AUTOFIX command can be used in conjunction with the /CHECKONLY and /CUSTOM options.

Question: Grinding To A Halt

My laptop is relatively old in PC terms, purchased December 2002. I recently reinstalled Windows, etc, to try to eliminate the problem I will outline, to no avail.

The laptop boots into Windows nice and quickly. If I don't do anything too intense, it will run fine for days on end without rebooting. However, there's two pieces of software I run quite often which use all of the CPU power. These programs will run fine for about 3 minutes, then the PC will grind to a halt. The pieces of software in question are:

Mixed In Key ( which scans MP3 and WAV files to detect BPM and key.
dbPowerAmp ( which is used to convert music files from one format to another (usually ripping from CD to MP3).

I have the latest versions of both of those pieces of software, and all the updates for Windows XP. Even when not running any other programs (aside from Zonealarm firewall and AVG Free anti-virus), and only one at a time, they will function perfectly well for a couple of minutes and then suddenly the performance will drop off. For example, re-encoding MP3s from one bitrate to another should yield a rate of 4x or greater throughout, which it used to do. However, after the first 2, the rate gradually drops to a much more disappointing 0.2x - yes, a fifth of the speed.

While running these programs, I've monitored CPU usage using TaskManager, and they continue to use maximum CPU, but their RAM usage drops considerably, often just aft... Read more

Question: Grinding Noise

Hello, I have recently heard what sounds like a grounding noise coming from my computer. I usually only notice it when the computer is searching for something (say a Google search), and I seem to especially notice it while searching on e-Bay. Once the site or page is found, it then stops making that sound. Is this something I should be concerned about? Is there anything I can do to stop it, or repair it? Does this mean the hard drive is about to crash? I have a Dell Computer, and Windows XP system. Thanks for the help.

Just to be on the safe side do a back up if you havent done.Open the case and try to isolate the noise.

Hi, can any one advise me? I have been getting a grinding noise from my PC roughly monthly since I obtained it in Nov. 2004, I think it may be when I push it a little??could this be the hard drive protesting ? it`s a pentium 4 3000ghz, asrobs.

Answer:GRINDING noise from PC

Some hard drives can get noisy when there is a lot of disc activity.......I have an IBM Deskstar 80GB drive which sounds a bit like a boiling kettle when working hard.It has done for the 3 years since I got it.Also some fans will speed up when temperatures rise and can become very loud.If this noise is infrequent,only happens when you are working the pc hard and most importantly not getting worse over time then I would be inclined to ignore it.If it's annoying you then you will need to track down the culprit and consider replacing it with a new quieter version.

I normally operate with Firefox. I am told that I should have a memory usage on Firefox of around 120000K. Over the last couple of weeks my PC is grinding to almost a standstill with a memory usage of nearly 400000K! At this point web pages take around a minute to change. The only way I can get over this is to reboot the computer, but within 45 minutes the MU has risen dramatically.

I also cannot use Windows Explorer or AOL browsers.

I also keep having a message stating that applications are failing to start '..........because MSVCP71dll was not found..' A souple of taps on 'Enter' clears this.

Question: CCNA + ?

Hello all-

I have a (military) background in aviation electronics. I graduated from an extended campus (military base) of Embry-Riddle with a 4 year degree and two minors. On a side note, I am only a private pilot. My degree qualifies me for a job in airport management, not 747 piloting. I won't get into my electronics based day job for fear of making this a rant.

I will be starting the CCNA classes here ( Note: check the IT certificates at the bottom) in March. Also, I'm working with just under 1.5 years worth of career changing time. (PM for any needed details on my sob story/strange life) I originally considered using my extra time/money to take the Linux/UNIX classes in parallel for a Linux cert.

I have a 1.5 year ticking clock, a great ability to study, learn, and take tests (Go Navy!!), and an unrelated degree with no IT experience. My question is this: Should I use my extra time and resources on the Linux/UNIX classes or one of the other programs? Maybe the MCSE? Finally, if so encouraged, I could possibly pull off 3 programs.

The results of these classes/certs will be a dramatic career change. I know that I will not start off making top dollar, or even middle dollar given the above information. I'm mostly looking for the most bang for my upcoming time in school.

Answer:CCNA + ?

Interesting. My opinion would be to try to get your foot in the door now. See if you can get a networking position, even if it is part-time. From what I have learned, companies value experience over certifications. If you can go into an interview and say that you have your CCNA, that is good. However, if you can go into an interview and provide your certification, along with a list of all of the real-world situations where you applied your skills, that will be even better.

Also, chance are, if you get into a network position, that the company will want to hang on to you after you prove your worth and get your certs.

I hope this will be at least some help, if any!

what is your general background with computers? just a user? enthusiast? administrator? regardless, to be fair, you could probably just dive right in...

if you want some hand holding, and depedant upon your timescales and finances, one way for you to achieve it would be through the cisco academy... (the other advantage of doing it this way is that a) you get to meet people along the way and b) they will have a decent lab of kit for you to play with).

alternatively, get yourself a couple of books, a few bits of kit of the bay, start to play - and then ask lots of questions!

I graduated with my BS in comp sci last may and I miss learning already, so I figure why not go for some certs. (all the compTIA ones seem pointless and too easy, cisco / MS is next)

I figure I might as well buy my own practice lab and materials, so i check ebay and craig's list. I found this setup

and the price fits my budget. I looked into taking the CCNA boot camp at new horizons and it would end up costing about $4500

Is the CCNA something I can tackle with some dedication and hard studying on my own? Or are the classes worth the price?

Also, Would that setup have everything I need to pass the current CCNA test?

Question: help me with ccna

iam preparing using todd lamle book for ccna and hotcerts.
com ccna guide , will i be able to go through the pass exams .
i heared its reall beast . wanted to know ur guys opinions

Answer:help me with ccna

Lammleís book is pretty good, but I wouldnít just read one book Ė read several. For example, in Toddís 5th ed Study guide, he has very little info on NAT. You may get questions or even a simlet about NAT on your test.

Another good book is the CCNA ICND Exam Certification Guide by Wendell Odom. Itís a bit dry but he does explains subnetting thoroughly. You then can use the short-cut tricks Lammle teaches you about subnetting to really be prepared.

By the way, if you donít know subbnetting very well, you will fail.

Finally, you need a router for some hands on training. In the past you could probably pass without it, but now those simlets will kick your ass without real hands-on experience. If you canít afford a real router (check ebay) your next best choice is a router simulator from Boson or Network Visualizer v5 from Lammle.

Use any list of exam type questions you get (hotcerts?) to simply test what you know; do not use them as a brain dump or as a study guide.

Just to repeat, if you canít do subnetting pretty much in your head, you will fail.
Good Luck!

Question: CCNA

I've heard the new test is pretty hard, but someone on the forums said it's mainly subnetting. Which is totally easy.

I've been cramming wtih the Dummies CCNA second edition, and i've already taken semester 1-4 in Cisco's Academy.

Is the hands part a full router configuration? Or small objectives, like install an ACL or RIP.

Any words for advise? Does everyone over react about how hard this test is?


There is a lot more than just subnetting. Routing, serial interface setups, ACLs, etc.

The sims are not complete setups; they were mostly "here's a network, host A can't talk to host C, fix it" and you had to either 'no shut' an interface, or assign a correct IP, or enable a routing protocol, etc.

Question: Ccna

Well I want to do my CCNA and would like to know you guy's opinion on it along on what book I should use. I started using this book last year but never finished studying for the exam seeing that I had to do my SAT's.
I hear everyone saying how challenging this thing is and scaring me off. I know it would not be as easy as the Network + but to make it so like hell?

btw I am A+ and Network + certified but have no experience with networks beyond 25 nodes or Cisco routers. guess I will need a good router sim.


heres the books i own.... all cisco press...
CCNA 1 and 2
CCNA 3 and 4
CCNA Intro Self Study Exam Cert. Guide
CCNA ICND Self Study Exam Verty Guide

also the self study guides come with a decent network might want to look into some night school type thing to get some hands on with the routers because the labs that the books come with kinda suck... the books will get you past the test but not the real world trouble shooting stuff....

Question: Url Ccna

Can someone provide me with an URL of a free tutorial site for the CCNA course? Thank you

Answer:Url Ccna

I am currently enroled in a CCNA course. I'm just about half way towards my CCNA.

We do all our work at the Cisco Academy online. And you may register for free I believe at this link. However, this is only the written information. You don't get any hands on experience.

But you may also find some more information at Cisco.

I may be able to answer some of your questions as well...

Good luck.

I have a Dell DImension Desktop (not a big Dell fan, but it was free, it's my only PC). Anyway, lately at startup I've been hearing a terrible grinding noise from insode the computer, it usually quiets down a bit later after startup, but a grinding/buzzing noise is always there to some degree.

I immediatly figured it was a HD problem, that the HD was grinding. I went to staples and picked up a new 80GB maxtor HD and installed it (removed the old one entirely). I re-installed windows at that point but the grinding noise IS STILL THERE! The noise is basically identical so I am starting to think that it was neve a HD issue, if it wasn't what else could possibly be grinding like that!? Maybe a fan somewhere? I'm not completely computer illiterate, but I obviously have no clue what's going on, please help me!


PS_ if it helps im running off of a GeForce FX 5200 256 MB Vid Card (ya, I know it's not the greatest), I havea GIG of staple's RAM and that's a bout all I think you'll need, plz help me out here!

Answer:GRINDING/BUZZING it the HD or..?(HLP!)

A fan is the only other moving part unless its a floppy or cd in the drives

Hello, now before anyone posts,
"oh, the ball bearing is broken" or w.e
hear me out
as we all know, its cold outside and when i came home today to turn on my pc, the card started to grind for no reason. i restarted and same thing. i noticed it was around 30C on the card, and i started up sc2 to see if it still worked.
i noticed, as the gpu got hotter and hotter, the less sound it made. at about 41C it completely stopped making any noise. i then turned off sc2 and still no noise. ive had this happen before. my question is. could the metal inside the card be contracting that much, that the fan actually comes in contact with it? i swear, the hotter it got, the less noise it made and vice versa.
anyone familiar with this behaviour?

Very weird indeed mate.

I've heard of cards suffering from whining capacitors and such (only happening when the card is put under extreme stress or when pushing VERY high frames per second [200 plus]).

Have you tried messing around with a fan profile? Like putting it all the way up to 100%? to see if the grinding gets worse or....

For the past few months my netbook has been running slower and slower, I dont know if its just Windows doing its stuff and slowing the computer down or if it is actuly Malware. So I ran the programs as it explained in the FAQ so please find attached the log files. SAS didnt make a log file but I guess that is because nothing was found. For some reason RootRepeal wouldnt run so I have also attached a zipped document with screen shots of the error messages. There was also an error with MGtools but it appeared to complete successully though, I have added this error to the document too.

Hello. Currently i Have in my PC:Q6600 2.4 ghz8800gts 312 DDR32gb of ram500gb WD sata HDDSound Blaster Audigy500watt PSUAlright so my computer has up and decided that it hates me. For about three months it worked without any major issues. I noticed some absurd artifacting with my GPU but decided i'd just replace it eventually. My problem is that recently my computer has gone nutty. Whenever I decide to do anything (open photoshop, install programs, ect) it starts to give me laggy sound. Windows itself takes about 5 minutes to get past that initial loading screen and then 1 or 2 minutes to actually load my user. Under a normal circumstance I would just guess CPU but it's stranger. Once photoshop opens it gives a GPU error, whatever, I get it, it's broken. Yet it works fine, no lag, nothing. I render videos, and nothing. I open fallout 3 and it lags until it gets to the menu and the sound is fine for the rest of the game. It seems to only lag on loading screens. About an hour ago I started hearing loud grinding noises from inside my case. All of this leads me to believe it may be my HDD. It seems that the sound skips any time the HDD is accessed but I'm not sure. So I wanted to get a second opinion.I ran a CPU stress test and it never got above 60C at 100% for 3 hours. I ran a ram test for 20 minutes with 0 errors. My GPU gets up to 72C with artifacting almost nonstop In games there are specific models that seem to make the oddest thing ever occur. Giant tr...

Answer:strange grinding noise

Two problems at the same time:1) Hard drive is going bad.  If the grinding noise is coming from the hard drive, that's means it's about to crap out on you.  Back up your data as soon as you can 'cause you may not get another chance...2) Video card.  99% of the time artifacts on the screen mean a video card problem.  The other 1% of the time it's drivers. have your marching orders.  Replace both the hard drive AND the video card.

Hi, I have the same/similar problem as dude 1234. Firefox using 100% CPUI didnt want to steal his post so I made my own.I have doing a bit of research on different things for browsers, this amongst them. (Well I dont know that its the browser actually).Every now and then my computer seems to just grind away, fans rev to their limit, windows wont open and the whole system drags for ages then to a total stop.It seems as though it is a memory problem, but having read that post, I wondered if it was my browser? I have a Pentium 4 CPU 3.00 Ghz 1.5GB of RAM. My computer doesnt always play up like that but it has its moments.The easiest way to get past it is to close everything and then restart F/F, this does cure it but is really inconvenient if I have lots of windows open.Can I do anything to cure this phenomenon please?

Answer:Same as dude 1234 CPU Grinding away at 100%?

Well your computer is better than mine and, anyway, I have investigated and determined its not a processor or memory problem. Try using Opera browser and see if you think that eliminated the problem. I'd be interested to know."Browser" is the name of the software you use to download and display web material. Examples of browsers are:- Firefox, Internet Explorer, Opera, Chrome.In case you are not familiar with the term "software", it means a computer program. Computers have hardware (all the electronic bits), and software (all the instructions that are given to the hardware to make it do something useful). My apologies if I have over-simplified this, but it sounded like you needed to know.

Hi, fairly new W10 install based on W7 upgrade.

Stock drivers for everything.

While playing computer games recently (particularly DOSBOX ones) I experience that the system simply grinds to a halt after a certain time.

Even trying to get a Task Manager/Process Manager running (ctrl-alt-del) then takes ages and nothing will close and I can only reboot the system.

There is no hard disk activity during that time. Memory is always around 2G (50% of 4G in use).

During this "system slowdown" any sound that is still playing in the computer game is then also "fragmented" or "slowmotioned" (the hagging, intermittend sound). Almost as if it is caused by audio.

I have no clue what this could be. Also during these slowdowns usually from what I can see there is no high CPU consumption.

I believe also sometimes after a while it restores itself, ie. some YouTube video playing in a browser will resume playing normally without all the delays and hickups.

Simply crawls to a halt. Do you people have any idea what this might be? And how to diagnose it, if in any case?

Currently I'm having to reset (reboot) this laptop time and time again. I did install a few audio tools / enhancers like "DFX" and another one (that I just removed) but I don't think this is related to those installs (?). I'm seriously... I believe I have no errors like this (the dragging of the computer and the audio) unless I'm playing a DOSBOX game.

And every DOSBOX game has it (t... Read more

Well, my HD has been making some weird noises... i cant tell if its the sound of grinding or if its the platter arm bouncing/getting caught somewhere...

The thing is, my hard drive works perfectly up to that point, and my computer only seems to do it under high stress for a long ammount of time. (as if the computer heating up might make a difference?) Ill be running a system-wide virus scan from Panda Antivirus Platinum, and at some random point it starts. This doesnt happen all the time it could happen at any time, like maybe installing a game after my computer has been on all day.

Its like a "(click, click.....................bwaAaaaaAAAAAAaaAAAAa)"

Not quite grinding its hard to explain

The drive's a Seagate 30gb.

My Hypothesis:
1. My $chitty power supply (a Deer 300w) at some point has trouble powering the drive, like maybe a jump in voltage... the the drive's internal parts would not be where the drive thinks they are, or maybe a lower voltage would cause things that are normally synchronized to get out of wack...

2. My ECS mobo installed in that particular system?
3. Could the drive be heating up too much? How could i test this?

Well anyways, if it starts to happen i have to completely turn the system off, as "restarting" via the button in the front doent acutally restart everything, and the problem would still occour.
Even after turning it completely off, i have to let it sit for about an hour before i can ... Read more

Answer:Odd Drive noises etc, grinding?

Your drive is dead. I've had this happen several times. before you use it again, i would suggest buy another dirve, copy the bad one to the good one and then have fun pulling the old one apart to see how it's broke. if you keep using it you'll lose all your information anywhere from a week to a month after it started making the noise.

This laptop was taking over 5 minutes to boot and even after it finished booting it would pretty much grind to a halt after running the internet browser. This laptop was only really used for facebook so there wasn't a lot installed on it and not a lot at start-up either, using process explorer I couldn't see anything using a stupid amount of memory or disk read/wright at all, so I was at a loss as to what was causing the slowness. After booting into safe mode and seeing that it was running as expected I figured there must be something running in the background causing the issues. So I ran through your README thread and Malwarebytes did remove some threats. This seems to have fixed the issue but the laptop still isn't responding quite as quickly as I would expect so I would appreciate it if someone could take a look at my log files to see if there is anything left behind?

I've only had my laptop for 3 months, and I've had the grinding sound for maybe a month now. It's mostly when I turn it on. But it also resumes grinding at a constant pace every few seconds, it grinds for a part of a second, even as I type this. It's a very low sound, though, unlike when it starts, it's a bit louder.

I've also been having slowdown issues, as I'm sure that's relevant.

My Dell Inspiron 1525 laptop fan is making off-and-on grinding sounds. What could cause this. I bought another fan, but cleaned out the old one and a clump of dust came out. It still makes that sound. Maybe I should replace the fan? Is this grinding noise dangerous?

Answer:Dell Inspiron Fan Grinding

Try cleaning it again, but if you have the new fan in hand, you are better off replacing it. Laptops have a hard enough time keeping cool when everything is working never mind when a fan is malfunctioning. I'm sure it is not pushing the amount of air it is supposed to.

I have four fans in my computer: one in the power supply, one in the processor, one on the back of the casing and one in my video card. At least one of them is making a horrible grinding or whirring noise when I switch it on first thing in the morning. It goes away after the computer has warmed up a bit and doesn't come back for the rest of the day, even if I power off for a while and power back on a bit later. It'll be back next morning though.

I've tried opening up the computer while the fan is making this sound and having a good listen but I can't tell for the life of me which fan it is. Does anyone know if there's a technique to find the dodgey fan amongst many fans? I tried searching on google but it always just returns results on how to fix fans or what to do in the case of discovering a noisy fan (but not how to distinguish which fan it is). My friend suggested sticking the end of a pencil in each fan while they're spinning to test and see if the noise stops but I don't like this idea, it sounds dangerous. I don't want to get electrocuted or damage the fans.

I did also try removing any dust from each fan (impossible for the PSU fan because its inside the PSU) in case that was the cause but nope, it still happens.
