GPU & CPU Usage Drops & Bios Changing it self

Question: GPU & CPU Usage Drops & Bios Changing it self

Okay so my computer is manly for playing games, but I've been having a problem for quite some time that I can't seem to be able to fix.
During gameplay at some points, totally randomly I start to have huge freezes, both CPU and GPU usage drop insanely, and following same do the fans, this usually happens for 1 or 2 minutes, sometimes even longer, a simple relog from the game fixes it. This also happens if let's say.. I go AFK from my game about 5 minutes or so, when I come back it's freezing ALOT.

I looked further into trying to fix this problem, I tried almost everything, until I had the idea to check my bios since I had previously overclocked my CPU (not overclocked atm) and surprise for me when I did a bios reset for default settings, this is what I saw:

That is changed by itself every boot.
And that is what is causing my GPU and CPU usage drops, I have no idea why that is changing by itself, at first I though it was AI Suite software from Asus that I had used before to overclock my CPU, but even with that uninstalled, it is happening.

I also thought about reinstalling my windows, but I would rather wait for Windows 10 to go public.

My Specs:

- Windows 8.1 Pro - 64 Bit
- Evga Supernova Nex650G 80+ Gold
- Asus Z87-Pro Socket 1150
- Intel Core i7 4770k 3.50ghz (3.9Ghz Turbo)
- Corsair Hydro H60 (2013)
- Gigabyte Windforce R9 280X 3GB GDDR5
- 8GB G.Skill Ripjaw-X 1600Mhz DDR3 (Dual)

PS: All drivers and software are always updated.

Preferred Solution: GPU & CPU Usage Drops & Bios Changing it self

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.)

Have you tried changing the cmos battery? The bios will not hold settings if the battery is bad.

After 20 min of gaming every 1 minute (IMAGE INCLUDED) gpu usage drops to 0% for 1 sec.VID drops to 0. Fps drops from 50 to 1fps. Gpu clock drops from 1137 to 1072 MHz. CPU usage drops from 40% to 15%. Voltage seems ok. It appears for 1 sec and after that it's working fine for ~1 min.
Played Outlast 2 everything was fine. Games with less requirements as cs go are working properly. FPS drops in Hitman, Sniper Ghost warrior 3, Mass Effect Andromeda.
ITS NOT TEMP ISSUE. PC is stable (benchmarking for over 30 mins). Drivers up to date.

Specs : (DxDiag INCLUDED)

What I tried:

Underclocking, undervolatege/overvoltage, forcing fan to 100%
Update/reinstall drivers
Opening case (PCI slot, cables, dust etc. check)
BIOS (fixed voltage (tried auto also), C1E is disabled, turbomode disabled)
Diagnostics - mdsched (ram), dxdiag, viruses

So for a couple months my PC has been relied annoying me so basically every time I play a game I get random fps drops and they aren't normal drop e.g. Going from 60-50 fps I go from 100 fps to 10 for a couple seconds I don't think it could be anything to do with my hardware because none of it is very old my CPU is an AMD fix 8350 which is a good CPU the only other component that I think it could be is my motherboard which is Asrock 970 EXTREME4 but I have no idea what i could be. I have also looked at maybe some software that could be the problem, but every time look at task manager while playing something but there is something that is affecting the CPU. So this where I don't know what to do, do I get a new CPU and motherboard or something else any ideas would be much appreciated

Answer:Cpu usage drops in games

Very likely a software issue. Something is running and using the cpu.

You can watch Task Manager as you noted. You could also disable everything not essential to the PC operation. After you confirm the problem stops, enable them again one at a time. When the problem reoccurs, you will then know what is causing the problem.

Am not sure if I'm posting in the correct area, if not please suggest/or reroute my submission to the correct subheading. I've attempted to resolve this cpu usage problem with little/no success. A few months ago I noticed my system freezing, stalling and video streaming and playback would stutter, freeze and or stall with latency issues in abundance. I also noticed Windows Task Manager at start up revealed: Processes = 61, CPU = 0%, Memory= 41% I've vacuumed the system exhaust vent and use a house fan to assist airflow. Though I read many possible solutions, most were a bit more complex than I am comfortable with or were for XP or Windows 7.

Am not a gamer. I've ran numerous a/v, systematic defrag, registry, junk file, etc scans. I don't know how to “shut down” or turn off processes nor reduce the cpu usage which in some cases red line. Any and all assistance is appreciated and gratefully accepted. PS: Am a beginner at this so please go easy on me!

I recently upgraded my gpu and now I'm playing some games. I played Chivalry medieval warfare, no problems. Now I'm trying to play Total War: Rome 2 and when I'm in battle the game freezes for a brief moment, and it does so constantly. I was curious about what was happening so I opened up msi afterburner to see what was happening to my gpu when this freezing occurs. It seems to be that the gpu usage drops to 0% every few seconds inexplicably and the gpu usage never even reaches 100%, it just hovers around 50-60%. The temp goes to a maximum of 75 degrees, so it can't be overheating. I was curious what would happen in other programs so I used kombustor and even when at 100% usage and 75 degrees, this freezing doesn't occur. So is it just the game? Do I need to do some tweaking with afterburner? It is all on defaulted settings so I didn't mess with anything. I doubt it is the hardware itself because it works fine elsewhere, perhaps it's just the game? Any help is highly appreciated.

As well as a number of other problems my GPU (GTX 670m) has been causing(My thread in the sound part of the forums..) It has also come to my attention that while playing any sort of game, from cube world to more demanding games, randomly the GPU usage will drop from 70%-90% to 10% which causes me to go from 60fps to like 5 fps.

I've tested this with and without over clocking and have no idea what is causing it. I dont think its the temperature of my GPU as it remains in the low 60s(c) while in game.

System info:
OS: Win 7 Home Premium 64 bit
GPU: GTX 670m
CPU: Intel i5 2430 @ 2.4ghz
Ram: 8gb
Model: Msi GT780dx

Answer:GPU usage drastic drops while gaming

Monitor your CPU usage with RealTemp while gaming. Make sure to select log file while gaming. Then look a the log file to see if the "MHz" suddenly dropped to 800MHz while gaming. If it does, it's throttling due to excessive heat. Then you can clean the heatsink and fan vents to make sure CPU doesn't get hot enough to throttle itself.

My network connection works fine with normal internet usage(my internet speed is less than 10Mbps).
I Also have setup Samba (home network sharing) and an Apache web server (both only is used in local network) .
When I use Apache or Samba to download/upload a large file on my local network (100Mbps full speed) after a few minutes or even less than a minute my connections drops suddenly. And both my local and internet access will be gone until I disable/enable network adapter or restart windows.
Yesterday I installed a clean copy of windows 10 AU , Problem is not solved.

Okay, well, here are a lot of details:
•My Specs, as complete as they can get (

•The computer was bought in Dec 2008, the video card was replaced in Aug 2011. The previous GPU was an ATI Radeon 4770 HD. I wiped all the drivers from the old one, and I double and triple checked for leftovers.

•All of my drivers are up to date.

•Disk fragmentation is not the issue - I defrag on a weekly basis.

•I thoroughly uninstall programs that I want to uninstall. Usually there's no registry leftovers.

•While we're on the topic of the registry - it's pretty clean - I don't think the issue lies in there.

•Temp files are wiped on a weekly basis.

•The problem started about a year and a half ago - in late 2011, or at least that's when I started noticing it as a reoccurring thing; I did not install something new that triggered it, I did not remove something either, as far as I know. It just kind of started happening.

•I play games often, but this happens when I've surfed the web for a while too.

•What exactly happens is the following: I start up the computer, let's say in the morning. Everything's fine, everything is running smoothly. I start up a game, let's say Fallout 3 (I know it's a glitchy game, but this has nothing to do with it, it's just a recent example.

I'm trying to run an old game, zoo tycoon 2, on windows 7. Apparently this game doesn't like it if you have more than 4 GB of ram; my laptop has 6.
I am able to go to msconfig and lower the max GB usage, but it's not worth it changing it every time just for this game.
Is there any way I can change the way this specific program runs so it will think I have less ram? Thanks

Answer:Changing memory usage

I don't think there is any way to do what you want.
The first thing to try with incompatible programs is compatibility mode, accessible from the programs properties. You could also try XP mode if it is supported by your edition of Windows 7. Failing that you could install and older OS, such as XP, under VirtualPC or VirtualBox.

What was the exact error message you were receiving?

Can we assume you are running Windows 7 64 bit? A 32 bit OS would be unable to use more than 4 GB of RAM.

A friend is having trouble with a desktop PC. I don't have all the info yet but here is what it is doing. If you open the Windows Task Manager and look at
the CPU usage it goes: 2%, 4%, 75%, 99% or 100%, then 75%, 4%, 2%,
and repeats constantly in about 1-2 second intervals at each percentage. It does this with no programs shown running.

Is there something particular to look at when I go to get more information on it?


Answer:Processor usage constantly changing.

In Task Manager, click on the Processes tab and then click on the CPU usage column to sort by % of processor usage. This will tell you what process(es) are causing the jump.

Is the unexplained jump in CPU usage resulting in any symptoms such as system freeze ups or slow performance? If not, I wouldn't be overly concerned about the issue unless symptoms develop.

Although this is not a complete list, here are a few of the things I've run across that can cause the CPU usage spikes you're describing:

* Certain antivirus programs (such as versions of Norton and McAfee).

* Two or more avtiivirus programs running at one time. In layman's terms, each thinks the other is a possible virus; this slows down the PC.

* If you get extended (<15 second at a time) CPU spikes to 100%, this can sometimes be a sign of either a corrupted Windows install or an impending failure of the hard drive.

Hope this info. helps.

since I changed my HDD to a SSD and reinstalled Windows 7 with 64bit on it, my system frequently runs into 100% CPU usage caused by the kernel module acpi.sys, as I found out with process explorer and confirmed by recording an ETL-file.

This problem occurs once an hour in average, sometimes after 10 minutes of system operation and sometimes after two hours, regardless which programs are running and if I am actively using the computer or not. When I notice a hanging and see in the process explorer window that 100% kernel cpu are in use, I allways need to save my work (what might take some minutes) and reboot the computer.

I could live with it, but this is quite nasty. My bios is up to date (version 2.70), as well as my other drivers (no errors and no viruses detected). In other forums I read, that such problems might be avoided, when changing the energy saving settings of Windows to something like never go into standby of the SSD, but this doesn't work in my case, as I deactivated all energy saving options in Windows and still have this probelm.

Is there maybe a not official bios update which could fix this problem?
I read in another forum, that an unofficial bios update from Dell fixed a similar problem of a Dell-computer.

Can anybody help me to solve this problem, please?

Details from Process Explorer:
The thread with TID 160 and start adress:

Similar problem like in this forum described for a Dell PC:

If, in contrast to the Dell-problem, there is no suitable bios-update for me, you might help me if you could tell me how to stop the kernel module (if it starts hanging or even before). Then I at least could avoid the frequent reboots.

A few weeks back, my C: drive started mysteriously filling up to the point where it was running out of space completely.
I would run CCleaner, organize things, clean out my downloads folder, and in some cases even delete some of the games I hadn't played in a while to make more room. A couple days would go by and it would be filling up again!
I finally figured out that my System Protection maximum disk usage was set to 50%, and Windows 7 was graciously creating many restore points every time I made any sort of change to my system (removing a game, for instance or installing a new one) and it was filling up my hard drive quickly.
I don't know how this got set to 50%, I certainly didn't do it as I didn't even know this existed. It is supposed to be 10% by default.
I changed it to 10% and deleted the old restore points. Things were back to normal for about a week, and then I noticed it was filling up again.
I just not checked it, and it was set back to 50% again! I changed it back down to 5% and again deleted the old restore points.
I have run Malwarebytes' Anti-Malware, and I have run a full scan using Avast! Free, and I have run a full scan using Spybot Search & Destroy, and none of these have caught the culprit. Could anyone help diagnose why my system protection settings keep getting changed to 50% maximum disk space being available for system restore points? I would like to set this to 5% or 10% and have it stay there... Read more

Answer:System protection maximum disk usage changing itself to 50%

The easiest (and best) solution is to completely disable system restore and begin using disc imaging software on a regular basis instead. It's more reliable, all encompassing, and infinitely better protection.

Hello all,
Got a new one. (For me anyway!)
On a couple of old boards I have it's possible to remove the BIOS chip from the board.
My question is, is it possible to switch these chips around from system to system?
Ie. A system that has BIOS that wont really let you configure the CPU speed, switch this BIOS chip with one that fits into the slot, but that would let you change these settings.
If so, what things to be aware of, peculiarities, setting changes, etc?

If anyone has any experience with the BIOS software then please let me know!

Oh and here are my specs if u need them:

AMD Phenom II X4 955 (AM3, 3.20 GHz, 8MB Total Cache),
Standard Heatsink & CPU Fan,
1000GB S-ATA 7200RPM Hard Drive,
802.11G 54mbps PCI Wireless Network Card

Kind Regards,

Question: Changing BIOS Logo

Could there be a more cumbersome process to get a new logo in there? 1) They don't have the size requirements in the readme...  just that when I run it, it'll tell me if it's too big or not.2) When you do run the tool, it tells you that the compressed size limit is 8192 bytes and does some unknown compression to get it there. It does say what the compressed size of the file you submitted is, though, so you're not completely clueless.3) I have to resize a black and white logo down to ~150x150 to get it to fit inside the 8 KB. When displayed on the screen, that puts it about the size of a business card. How can anyone see that?  Any tips out there for making this work a bit more as expected?

If I change the hdd from ide to ahci does that change any data on the hdd or just how the bios reads the drive?

Answer:Changing HDD from IDE to AHCI in bios

It doesn't change any data on the drive.

Be aware that if your going to change from IDE to AHCI while Windows is installed. Your going to get a BSOD.

Search google for the registry edits necessary to make Windows boot after the change.

How would I go about this. It took time and digging but I found a proper bios upgrade for my PC to allow over clocking and modding. But I know in the past you had to use a formated floppy to flash or upgrade bios.

Is there a way to do it otherwise as no PC i own has a floppy drive anymore.

Answer:Changing bios without floppy

It depends on your motherboard. Many new motherboards will allow you to flash BIOS from within Windows.

I have an Asus board with EUFI and cannot boot a Linux OS form a stick for trying out the VMware with Mint MATE.
Now it has been suggested that maybe the EUFI boot set up is not allowing the machine to boot from the stick the ISO is on and to change the BIOS to legacy.
Now I have seen a few things in Youtube and some mentioned reinstalls and such and there is somewhere I don't want to go right now in case I cannot get back the EUFI and as for a reinstall I have just done one and also do not want that.

So what is the go with the BIOS I thought the boot order could just be changed as the old system use to be - or can it?

I just type this all in and then it wouldn't post.

I received an M-Audio Delta Audiophile 2496 audio controller card from a friend so that my son could record some of his own music. I installed the card in a PCI-slot and upgraded the driver through M-Audio website. After a day the computer would no longer boot up. It would freeze before it got to the welcome screen. I changed PCI slots and it booted up 1-2 times and then froze again.

When I removed the card, the computer booted fine. As my son was anxious to use the new sound card to record with, I went to M-Audio website and tried a few things - none of which worked - from the FAQs.

One FAQ suggested updating drivers for the VIA 4-in-1 chipset. I downloaded the update and installed it. When I rebooted, the computer would get to the welcome screen and I'd choose my icon and then it would stall at the point of saying "loading your personal settings". It didn't freeze as the mouse pointer moved. I tried rebooting a few times. Then I tried a system restore, which didn't help.

I went into the BIOS and checked loaded 'failsafe defaults'. Now the computer just makes one long beep every 5-10 seconds. The hard drive LED remains lit. The CD and DVD drive LEDs light up. The wireless card LED sights up. But the computer doesn't even get to the first screen.

I would try clearing the CMOS by moving the appropriate jumpers on the motherboard CMOS pins. Your motherboard manual illustrates what to do. If you don't have your manual handy, go to the Biostar website and download the pdf manual or click here. See page 12.

I recently got a new Dell Dimension 9100, and it came with a DVD-Rom and DVD-R/RW. I'm not sure about the information for the DVD-R/RW, as my BIOS is currently not recognizing it. I am using a Netgear 54 Mbps Wireless USB 2.0 wireless adapter, and it is somehow causing my DVD-R/RW to not be recognized by the BIOS.

When the wireless adapter is plugged in, upon booting the computer I'll be told that it "cannot find Drive 5." I looked in the BIOS, and the DVD-R/RW is Drive 5. I have to take the wireless adapter out and reboot one or two times before the BIOS will recognize it. When I boot it up and the drive works, I can put the wireless adapter in and both will work. But then I shut down the computer, and when I reboot with the adapter in, it won't work. When I reboot with the adapter out, I still get that "Drive 5" message, but I only get it after both the DVD-R/RW and wireless adapter were used.

This is frustrating. My father doesn't know what to do, and I haven't been able to find any information that could help me. Is there any way I can change the DVD-R/RW from Drive 5 to something else and maybe solve this? If I've managed to confuse you, I'm sorry; just tell me and I'll try to explain.

Answer:Changing the name of a drive in BIOS?

Try playing around with IRQ and plug an play settings. Try toggling legacy USB/USB interrupt, plug and play BIOS, APIC, disable VGA interrupt. Disable any devices you don't use in BIOS - turn off parallel and serial ports for example.

My master boot drive is on Ch0 (IDE) my SSD is on Ch4 (SATA) in the bios. How do I get my SSD to Ch0 so it's seen as the Windows Boot Drive (Master) for Windows to Boot, it is just a matter of it plugged into the right SATA port on the board ? I've had situations like this before, forgot how to solve

Answer:Changing HDD Channels in BIOS

There is no priority or hierarchy to drive position in SATA. All hard disks are treated as equal drives and it is the OS that determines the boot priority. But if you want the SSD to be recognized in the BIOS as ch0 then be sure to plug it into SATA port 1 on the motherboard.

I'm curious that you have one drive in legacy IDE mode on a SATA controller with an SSD drive. It is recommended that SSD's be run in AHCI mode on SATA controllers. This does not address your problem, but it makes me wonder if you have a PATA controller on the motherboard and an old IDE hard drive connected to it?

If there was an operating system installed on the "IDE" drive previously and you have since installed an OS on the SSD then that may explain why you are having the problem. A better description of your system and what you have done would help. If you could post a screenshot of your Disk Management window then we could see what is going on in a second.

Next day (26th December 2015) in the morning i switched on my laptop. After switching it ON. My display said that the there is a problem booting. So after going into BIOS. The INFROMATION showed that the Hard Disc is not DETECTED. So i made a complaint in the customer care (LENOVO). So one of LENOVO'S officials came to examine my laptop. The first thing they did is replace my hard disc with a new one. After restarting the laptop it still couldn't read the Hard Disc.

I'm using a prehistoric BIOS circa 2001 on a computer that lost it's WININET.dll file for XP Pro.

I would like to boot from a slave drive which has XP Home. The BIOS sees these all drives, but I want to know if I can simply change the BIOS to boot from the slave drive, INSTEAD OF physically changing the jumpers to make it the master drive. (I've opened this computer too many times already).


Answer:Change BIOS without changing jumpers?

A lot of BIOSs have the ability to boot from whatever hard drive you want (usually displayed by the name, like ST310086). I don't know about your specific BIOS, but you sound like a guy that can work your way around a BIOS interface. You should be able to find it.

It is safe just to swap it, I'd prefer turning the power off before doing it CMOS won't propably clear within the couple of tens of seconds it takes at most, and even if it would clear, you'd just need to set the settings back.

I have changed a setting that says top performance in the DRAM menu of BIOS. It changed the latency from 3 to 2 I think. Nowhen trying to start the PC there is just a continuous beep and nothing else. I there anyway to get back into the BIOS to change it back?

Answer:PC will not start up since changing BIOS setting

It could be a duff connection either card to mobo (remove and replace carefully and firmly), or monitor to motherboard. Check these before you switch on again.If the card has really failed and there is integral video in the mobo, you could try removing your MX400, change the monitor lead to the other video out socket at the back of the mobo and hope your computer will accept this by default.Perhaps you can update us with the result if no one comes up with a cast iron idea!

I bought the top-rated budget computer at the end of last year (the Eclipse Elite i675n86gt, obviously before reading consumer reviews) and have had a problem with a red tint on monitor since it arrived.Under advice I have changed the chipset under BIOS to point to the graphics card on the motherboard - by changing from BIOS chipset option "PCI" to "onboard".This has fixed the problem or at least provided a workaround.However I'd really like to use the £50 superior "256MB PCI Express Sparkle nVidia GeForce 8600 GT" !!My question is I noticed that as well as PCI and onboard there was a third chipset option: PCI-express.Since the Eclipse Elite i675n86gt "256MB PCI Express Sparkle nVidia GeForce 8600 GT" is clearly described as a PCI express card can the problem be that my BIOS has just been specifying the wrong sort of card ?or does a red tint simply suggest the card is broken ??sorry if this is an obvious question ?I am nervous of simply switching my BIOS to the PCI express chipset in case this isn't the problem and I completely lose my monitor - the problem would be hard to fix with a blank screen !thanks in advance

Answer:changing chipset under BIOS to fix red tint

Firstly, why are Eclipse not fixing this problem??Your 8600gt is certainly PCI-expressAre you saying you've had to switch to using onboard graphics, and connected the monitor lead to the video socket on the back of the motherboard rather than the one on the graphics card?Is the graphics card still installed?

Answer:Bios Keeps changing boot order...

When you reinstalled with the single HD, did you change the SATA controller to AHCI or IDE mode? Or is it still set ot RAID? Check all BIOS settings related to SATA, IDE or RAID drives controller.

How many HD's are connected? Try booting with only the Win7 HD plugged in.

You say that "SONY" is listed as the First boot device. Sony what? Can you be more specific as to what device this is? Try setting the HD upon which Win7 is installed as first to boot if it's not.

Next try resetting the CMOS: Clear CMOS - 3 Ways to Clear the CMOS - Reset BIOS

I seem to be having a problem with either my CPU or my Motherboard or my BIOS or somthing. Somthing on my computer keeps changing the cpu speed in the bios at seemingly random times to 533.3mhz speed, when it should be 2.4ghz. I originaly thought it was Ntune because that has the ability to change bios settings without having to restart, but after i removed it and the problem persisted i thought maybe the processor or motherboard or BIOS is damaged. Every time the cpu gets set to 533.3mhz i start experiencing extreme lag and eventualy the computer locks up completley with the sound looping if anythings playing. SOmetimes but rarely it will give me the Blue screen but then close before i can read it. Every time this happends i go into the BIOS and it says the CPU is operating at 533.3mhz and the CPU multiplyer is 2x.

I am having trouble with the instillation of some application/scripts that are coded for Windows 7. After many days of testing, the error appears to be related to the Helix BIOS entry under Preinstalled OS license. This attribute is set to Win8 Pro, the OS that the system was shipped with.

The "preinstalled OS" info on the BIOS screen does not include windows7 stuff. If you have win8 pro installed, you have downgrade rights, (stored somewhere you cannot see), but those downgrade rights only apply to windows 8 professional installed from Lenovo recovery disks. If you started with win8 pro, you will have an SLIC 2.1 segment in your BIOS that will allow OEM win7 to activate automatically. For windows7 enterprise, you need to manually enter the key associated with your license

Hello Joe and welcome to Seven Forums.

Since the BIOS is part of the motherboard, I think it's very possible that even computers from the same manufacturer could use different motherboards and different BIOS. (As of May 16, 2012 Microsoft recognized about 60 different BIOS manufacturers.)

Since each BIOS probably has its own specific way to access changeable parameters, I'm not sure that a command line or batch file approach would work. Perhaps some more knowledgeable Forum members will jump in with a better suggestion.

Answer:Changing From BIOS Motherboard to UEFI

I don't know how likely that is.

Before you try any transplant, I strongly recommend that you image your HD. I've used Acronis True Image, although it's not completely foolproof.

You may be able to simply swap motherboards, Windows 7 detects the hardware changes, and off you go. You may have to install a few new drivers.

If that doesn't work, you may be able to use the sysprep utility on your WIndows installation, with the "generalize" switch. That's intended to allow producing a generic Windows installation for diverse hardware. (Drivers are removed.)

If all else fails, re-install Windows. I hope that you aren't using an OEM copy of Windows. Microsoft may not be willing to activate it on a new system.

Will updating my BIOS changs the date of installation? If not, does the BIOS need to be replaced for this to occur? I am trying to apply to a job but their software is telling them my computer is too old. I've checked and the date they are showing is the BIOS date exactly. Can this be fixed without exorbitant cost?

Answer:Changing BIOS date of install

They're scanning what now? They have asked you to install software so the can scan for the date of your BIOS?

Is this a job with the NSA? Do you mind telling me what kind of Job requires you to do this? You're running Windows 8.1. How new do they want it?

I just purchased a few upgrades for computer and before i replaced my RAM i went into the BIOS to change the settings of the RAM to 1600, which was at 1333 and did a reset before i changed anything out.
After the reset it went to a black screen and the monitor brings up the amber button,and after a few times of resetting, a black screen with a flashing cursor came up, this was without even changing any of my new pieces in yet. I looked into my computer to see and my graphic cards fan wasn't spinning, so i replaced my graphic card and the fan began to spin but still getting a black screen with nothing on it, not even a cursor anymore.
I decided to do a bench test to figure this out and just used the essentials of CPU, graphic card, 1 stick of 1333-2gb RAM, PSU, and the MOBO. Made sure everything was plugged in, including the 24 pin, the 4 pin, the graphic card, and the CPU Fan. Everything is getting power, the CPU fan is running, graphic card is spinning, the MOBO has the green light indicating its on, but still the black screen of death.
Ive tried 3 different graphic cards, different monitors, different RAM(2 & 4gb), a different PSU, and still nothing. I made sure all my jumpers were on correct, removed the CMOS battery, swapped the battery out, did a jumper reset, and im not getting any beeps, but still.... nothing

I'm currently looking for a way to change all of our Laptop & Workstation (Approx 250+ machines) BIOS passwords using a remote tool if possible. The majority of laptops are Latitude and the workstations OptiPlex although most of the laptops have BitLocker activated.
We also use Empirum software to push out software if this would be of any help.

I have been looking around and into using the Dell Client Configuration Utility and also the OpenManage tool although I'm not too sure if they would work for us due to us using BitLocker.

Any help would be much appreciated.

Thanks in advance.

I just recently had to upgrade to a 880gm-ud2h motherboard after my old one died (an older model, also updated the RAM and Processor, but not the hard drives or video card) but now that I've done all this, something has messed up with Windows.
Whenever I start the computer, windows will seem to start normally, then a BSOD will flash for less than a second before the computer reboots and demands that I run the System Repair thing for Windows. After running this three times without effect, I decided that I was better off installing a new OS (I lost my repair disk), and created a USB bootable for Ubuntu.
However, with this USB boot drive plugged in, hitting F12 during boot up brings up the BIOS boot order as normal, but no matter which option I choose nothing changes.

Can anybody help me with this problem?

Answer:Boot order of BIOS isn't changing

Well for some reason it finally decided to work, but now the computer won't go past a black screen that says "Loading Operating System..." and it sat there for about fifteen, twenty minutes,.

I was just wondering if it's possible to change from award bios to ami without changing the actual chip?

Answer:Can I switch bios without changing chip?

I have to say that I seriously doubt it, but I do not know for sure. I don't even know how you would go about that. I mean you need the bios to boot up and run your computer so how can you simply override all that information. Your best bet is to take a blank chip and program it with the new AMI bios and use it.

I'm sure other people know more about this than I do, but this is just my opinion. Just curious, but why exactly would you want to do this???

Hi i am putting in a new processor K6 550MH if i need to update the bios do i update with the old processor a 350MH still on board or update after i replace with the new?

Answer:changing processor and updating bios

If you are certain that you need to update the bios to accomodate the new processor speed - you might want to check the motherboard manual first - then my preference would be to do the updated with the old processor in place. That way you know you have a known good configuration. You can then change the processor out and on boot up see that it has been detected correctly.If you change the proceesor first and then something happens on boot up you may be forced to go back to the old processor.

How can I update my bios to allow booting from a USB Flash drive. My bios is American Megatrends 6.07, 5/4/2011 and the only options are CD, Hard Drive, floppy. Is there a way to change this? In testing the Windows 10 Repair Disc I created, my system froze at the 'choose keyboard layout' blue screen. I could not use the usb mouse or usb keyboard. As a result, I had to recover my system back to windows 7 using my Norton Ghost recovery disk and the backups I had made before the downloading windows 10.

Answer:T520 - Changing Boot order in BIOS

Hi rsbonini,
I moved your post here from an old thread that was about managing UEFI BIOS boot order with scripts...
I wonder if you're being tripped up by the same thing that got me with my T420:  The ">Boot" line in BIOS -> Start Up looks like a heading for the rest of the page, but it actually links to an expandable menu. (That's what the ">" is indicating, I guess).  This got me and a few of my friends.
Highlight that ">"Boot" line and hit enter, and you should get the boot priority list with instructions on how to change it in the right pane.
Apologies if I've misunderstood,

Hello! I was just wondering what were the effects of changing the BIOS time on Windows 10? I've heard it can do some damage to files and programs (specifically antiviruses, I've heard those can be broken). What are such effects and are they reversible by putting the BIOS time back to the proper time? I only intend to change the time by a couple of hours or so.

Answer:Effects of changing BIOS time on Windows 10?

I've had to do it before when on deployment and not connected to the internet for weeks at a time to keep some of my games running. When I did finally connect to the internet I forgot to change the time to the current date/time and all I experienced was a lot of webpage errors until I figured out I needed to update the date/time.

I don't run third party anti-anything programs though.

I have an IDE removeable hard drive. After removing it, the BIOS changes the boot sequence and attempts to start from a drive that does not have an OS on it.

What I want to do is to find a way to, at least, nail down my C: which has its own partition on one of the two hard drives that are permanently in the computer.

Likewise, it does the same thing all over again after I re-insert the removeable hard drive into its slot.

I'm reformatting my cousin's Dell Inspiron 1520 laptop, but need to change my BIOS settings to hit the disc drive first. Here's my problem.

Unfortunately, the LCD is cracked. In some way to spite me, the left side of the screen still works. Just enough for me to see the first letter of what I'm on.

I need help with anyone who has the same laptop, or knows how to navigate the dell BIOS. I need to know which field will allow me to change the boot order. After that, I need to know, from how it's set up from the factory, how to change the order and how many times I need to press the button to change the boot priority to CD-ROM first.

Basically, what I'm asking is for you to walk me through this, cause I'm going in completely blind on this one.

Answer:Changing Dell BIOS settings blind.

Well if the screen is cracked you are going to have a really hard time reading it depending on how bad it's cracked.

You may want to hook up a external display.

When you first turn on your pc you should get an option like Push F12 for boot menu and then select your cd rom drive.

My keyboard is not working. The easy answer for the moment would be to use a USB keyboard, except that option is disabled in the BIOS.

Is there any way to change or reset the BIOS without a keyboard?

Answer:Satellite L100-113 - Changing BIOS without a keyboard


Try to boot the Windows OS and start the Toshiba Assist.
There you can find the Toshiba HWSetup. This tool contains some options which could be changed in BIOS too.

So I think there could be a option which enables the USB keyboard support.
I think this should be possible using the USB mouse.

Hi everyone, here's my problem. After changing my BIOS settings, my computer hung on a black screen. I removed and reseeded my battery to reset the CMOS, and I got back in. But my default settings set my processor at 1.24 GHz, when it should be at 2.08 GHz. This is because the FSB speed in my BIOS is set at 100MHz. Setting it to 166MHz would put it back to normal, but everytime I do it, it hangs on a black screen at reboot again. Forcing me to ressed the battery again to get anywhere. Any help would be absolutely fantastic!

For some reason, yesterday my D: disapeared! I tried to do add hardware but it wouldn't detect it! So I went into the BIOS and I think the problem is that my Hard Drive is the Primary Master and my cd rom is the secondary master. Shouldn't my cd-rom be the primary slave?? If this isn't the problem, what is? Thanks.
edit: There are no other cd-rom drives in my computer, I'm running Win98 and the cd-rom is a plextor. It just disapeared from windows. My BIOS recognizes it mut windows doens't. Please help. Thanks.

Hi, I bought a Lenovo Thinkpad Edge E320 with 128GB SSD but without OS. I installed Windows 7 and ubuntu and had issues with dual booting because of the UEFI. So I decided to change from UEFI to legacy mode in bios. After that I cann't enter BIOS any longer. If I press F1 on start I get "Entering BIOS Setup" but the BIOS doesn't open instead immediatly Windows starts. The same with F12 to select the boot drive selection the message appears but the menu doesn't open instead Windows starts. How can I enter again the BIOS or reset the options? I tried BIOS Update with BOOT Cd from Lenovo support site but it didn't help. Thank you for advice Best regards bubbas

Answer:Edge E320, can't enter bios after changing from ue...

Hi bubbas and welcome to the Community,
This is a long shot, but take out the hard drive, the battery and unplug the ac adapter and hold the power button down for about 15 seconds.
Then plug in just the ac adapter without the battery or hard drive and start the machine and see if you can get into the bios.
If you can, reload the defaults and reboot.  See if you can get in again and you might want to check the F12 to see if that works.
