No signal to monitor

Question: No signal to monitor

I have a pc build and have been using it for a few months now and for some reason signal is not found on my monitor. I have tried different cables and even taking out the graphics card. I?m not hearing any beeping and everything seems to be connected correctly. I have a gigabyte graphics card but can?t remember the name of it. I also have a MSI b350m gaming pro mother board.

Preferred Solution: No signal to monitor

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.)

Answer: No signal to monitor

Without a detailed description of the hardware(processor, graphic card, power supply, etc.) in your PC and a description of the monitor connected to it and what Windows version is running in your PC, you make it difficult or impossible to help you.

Sorry for the long text, I'm trying to send as much information i have.

Hello forums!
A few years ago i built a new gaming pc because i wanted to be able to play high quality games. But since day 1 i've had nothing but problems. Whenever i play one of my high quality games such as "Assassins Creed, Tomb Raider, Battlefield 3 or Primal Carnage" the monitor goes completely blank showing a "no signal to monitor" sign after gaming for between 5 minutes to up to 2-3 hours. The monitor sometimes also shows different color stripes either for examples: orange, pink or grey. The sound of my friends on skype usually keeps going for about 20 seconds before going silent, the sound of the game shuts off instantly or goes in a loop or starts with a loud buzzing sound. The fans and the LED's on my pc are still going but i can't control anything on the pc making me have to force restart my pc on the power button.
I've been on this forum before talking to this guy who is helping me but he's been quite busy lately so i need some extra help.
I've updated all drivers to latest, i never overheat, the GPU does not go over 51C when gaming and CPU never goes over 51C either.
I've upgraded my 650W powersupply to a 850W power supply and is one of the highest rated best performance power supplies you can find.
I tried to RMA my graphics card but they found nothing wrong with it and sent it back.

My monitor (ViewSonic VA720) is set to turn off after 20 min in the WinXP Power Options Properties. The monitor goes into standby correctly, but will will oftentime not come back on after resuming. It will just show a black screen and the lights on the monitor indicate it's in standby. Pressing the power button on the monitor seems to have to effect. When turning it back on it will say signal out of range, and then go back into standby. My system is:

AthlonXP 2200+
MSI 6600GT 128MB AGP (Driver 163.75)
Windows XP SP2

The only way to fix this is to reboot the machine, which is not always convenient. Any suggestions? Thanks.

Hi everyone
We've just picked up a second hand PC & Monitor that we saw booted up and working before we paid for it.
We've connected it with all the same cables that the chap gave us - but the monitor is saying that it can't get a signal (VGA no signal) and then goes into sleep mode.
It's a Compaq Presario - please can anyone give any idea as to what is possibly wrong?

Answer:just bought a PC and monitor - monitor can't get signal

Check the rear of the PC. You might have two connections there. You need to connect to the port that's on the horizontally fixed graphics card and not the vertical motherboard's connection.

I've suddenly gotten this problem: Return to my pc after a while and find that the monitor has gone black and pressing the power button gives the message "No signal". Moving the mouse or pressing buttons don't result in a wake-up. The hard disk lamp is blinking so it seems it's working (in this case video capture).
I have turned off the screen saver and I don't use put computer/HD to sleep.
Anyone having a clue?

Answer:No signal to monitor - monitor has gone black

I would probably say that there's a part that's burned out inside it. It's a specific part that I don't actually remember the name of. Don't know how long you've had it but I know that it happened to one of my Hannspree monitors. If I were you I'd Google the make of your monitor going black because it's not technically a Windows issue. As soon as I did a little research I determined that I could send it to the manufacturer to be repaired luckily it only initially cost me $50 and I made a mistake sending it Fed Ex.
**Actually. Can you get the menu up for the monitor pressing the menu button on the monitor itself? If not there's a problem in the monitor like I mentioned.
Having two monitors obviously is great because you'll know it's not the graphics card.

So at my friend's house, whenever it rains or bad cloudy day, there is no WiFi signal sending from main floor to 2nd floor. So I recommend them to install a Linksys RE6400 range extender to boost the signal, on the existing Linksys AC1200 unit, and the setup of that extender is wacky. It somehow works after a while, but w/o the 5GHz band. But the other day when they re-plug in that extender, there is no signal (even on a sunny day)

So today, I try to help them to re-initialize that RE6400 by going thru the instruction, totally no signal(on a sunny day). Now, assuming it's a defective DOA unit, is there some range extender that is high quality ? And has a nice and simple setup software? (just in case pushing the WPS button doesn't work)

And more importantly, should we unplug the extender when you don't use it? Or are you suppose to always leave it plug in? If you unplug it, would you lost all the setting on that extender?

Answer:no WiFi signal during rainy day and signal booster doesn't work, & what's the good signal extender?

Use a wire. Extend WiFi via remotely placed access points.

One day i get up and try to use the computer. I get a no signal floating from my monitor even though i still hear the post beeps my computer beeps after it sucessfully boots up. I reset my computer several times to no avail. I try reseating my graphics card and nothing. I take out the graphics card and try to boot with onboard graphics. I see the normal boot up text and beeps, but after that, the screen is just black. I borrow a graphics card from a friend and it goes back to the no signal onscreen.

Hey! i have been playing black desert online lately,which means that my pc have been going non stop for the last two weeks. it has not been turne off once. i have ofc put my pc screen(AOC) in "slumber mode",but when i pressed the keyboard it would turn on again. Now suddenly, i was playing, my monitor turned black and gave me the sign " no signal". i have checked the cable (HDMI) everything was fine,have tried different inputs,still does not work.

Should i just give it a rest for a while or is there some other issue perhaps?

Answer:monitor does not get a signal

If you have been gaming on it NONSTOP and haven't powered it off even once in the last 2 weeks, it's my guess something overheated and caused damage to the system. I would take off the side panel and see if you see anything that looks burnt/charred or if you smell anything "burnt."

Using win7 home premier for 2 months no problems. Went away for 30 days, came home and booted the computer (HP s3220n). After the windows splash screen, the monitor (Westinghouse LCM-22w3) read "no signal". Booted into safe mode & uninstalled the graphic device (nvidia geforce 6150se nforce 430 onboard) in the device manager and rebooted. Same result. Restored to a previous date. Same result. Installed Nvidia drivers, various dates, same results. Installed window driver for the graphic adapter, same result. Reset monitor. Same result.
Currently using VGA driver, can't obtain the resolutions I could with the correct drivers. Any ideas?

Answer:No Signal on monitor

Borrowed another monitor, started windows. Installed the windows Nvida driver.
Set the driver for low colors and low resolution. Switched monitors back to mine and rebooted. Video okay. Adjusted resolution and colors in small steps, rebooting after every change. After adjusting back to 1680 x 1050 32 bit color everything is okay.
I will not let windows update the video driver.
I will hold on to the borrowed monitor for a period of time.

Hi everyone,

Yesterday I reported that I had bought a new custom built PC but when I connected it up to my old monitor a 'No Signal' message was displayed when the PC was booted and then the monitor went into standby mode.

After a couple of hours work and some useful guidance from yourselves I got it to work. I'm not too sure how though! I then proceeded to set up the Internet connections and change the resolution of the screen. I also attempted to install some antivirus software provided to me by the company I bought the PC off. This failed to install for some reason and I then got a message saying that I had to restart the PC.

Upon doing this, I found myself back at square one with the monitor saying 'No Signal'. What is going on?

Somebody help me please!!!!!!!!!:cry

Answer:No signal on monitor (again)!

If your monitor lead connection is loose, at the video connection of your computer, that would be the first place I would start, as directed previously- if it does not screw up tightly, then check it out (still being careful not to overtighten)
As simple as it says - no signal,- is pointing to that. Your graphics card is new ? replacement, old one ?
As the monitor works elsewhere, I would recheck as advised before.

When I boot up my system, the monitor does not receive a signal unless I flip the rocker switch on the back panel at the power supply, off and on again, then it will receive the signal and boot up. However that is an improper shut down. I have tested other power supplies and the monitor, as well as checked the connections and pins.
Can someone please advise me?

Faulty Motherboard, I have seen this occur, if you flip the power switch before windows starts (most BIOS POST's in 10-15 seconds) then it isnt an improper shutdown.

You can swap out the PSU and ensure all your cards and peripherals are seated correctly, but I think the Mobo is a definate loss.

Hullo, my comp came back from RMA after 1 million years so I turned it on. Everything worked fine even my old data/games/programs were on the hardrive so I turned it off. Took out the PSU/GPU replaced them and now I get a no signal on the monitor. Everything powers up fans start spinning etc....I need help. This new computer has been a nightmare for me.

Also I replaced the old PSU/GPU and nothing there either


Answer:New PSU/GPU = No Signal on monitor

Just to be clear first - by "PSU/GPU" you mean you replaced the power supply (PSU) and also the graphics "card", correct? I say that because GPU means graphics processing unit and is the primary processing unit found on graphics cards, and integrated with motherboards using on-board graphics. There is no single device called PSU/GPU.

I have had an issue like that before, tho my issue was kinda stupid, but I share it anyways,

I have a game card installed in my computer, and found out that your monitor "HAS" to be plugged in to the game card and not the motherboard itself, otherwise it wont turn on, or you get a message sayin, please reattach to game card on screen, also check to make sure that your monitor cable lines arn't kinked in anyway and check the heads for any bent wires that dont like they are suppose to be. that would be my guess, common error for me lol hope this helps

But the monitor does work in another computer?
Some graphics cards will not work with limited memory... I would be sure you have 1 Gb, and preferable 2 GB, depending on what the new graphics card might be.
But we can assume you have thoroughly gone over the checklist that came with the video graphics card? And you installed the drivers from the enclosed disk?
Does the computer still work with the old video graphics card?
Do you have any red or yellow flags in the Device Manager?

In short I had just finished playing some gsmes on steam with a couple of friends and the the screen went to no signal. I could still hear them on Skype so the pc was still working. Now when I stsrt up the pc (Win 7) I can hear the fans start, see the gpu fan on and hear the hdd, but there is no post. Is there any easy way to find out if it's the gpu?

Answer:No signal on pc monitor

Sure. A quick way would be to pull the card and use the onboard or onchip video that is part of the 3570. This only takes a few seconds to do.

You left out probably the most important part; what pw supply you have installed.

Question: No Monitor Signal

Ok, I am new at building my own computer, but I have done just this. I properly attached all of the wiring and everything is connected right. My problem is that when I turn on the computer I get a no signal message. The monitor itself works fine, as does the card. The motherboard is a SiS 648FX, and the card is an ATI Radeon 9200 AGP. Should the system boot right up to bios on the first start, or is there somthing I need to do before I will get a visual? If it helps diagnose the problem, I have no keyboard lights, but mouse is on, and my reset button flashes the light, but doesn't reset the system. Could this be a motherboard or CPU problem, or am I just retarded?

Answer:No Monitor Signal

Hm...  What are the specs for the comp?  Well, I would advise you try running the computer with the integrated video card (If it has one), and see if you can get to BIOS from there.Oh, and yes, I believe you're supposed to see BIOS on your first boot.Btw, does your computer make any beeps when you turn it on?

The problem is that i'm not geting image on the monitor, it says "no signal". The problem is not from the monitor because it works in another computer.

It started happening after I changed several things in my computer. I have a Medion Titanium MD8383 XL that has a Nvidia Geforce 6610 XL. I changed the memory cards from two 258Mb to two 512Mb, and installed a new CPU cooler, Verax quattro I , and a new VGA cooler VF-700AlCu.

I've read a few of these threads I've seen but none of the solutions suggested haven't helped.

Midway through playing a game, both monitors flash black and display a "no signal" message. I've tried using another monitor with my computer with the same problem. I left the screens black for about five minutes before I decided to reset, and now I simply can't get anything on my monitors (both of which work on another system in the house).

Is there anything anyone can suggest that may help?
I've tried:

Cleaning my base unit.
Testing monitors with another system.
Testing another system with monitors.
Despite seeing no image, I tried to boot into safe mode.

Unfortunately, the only system specs I can remember are that I'm on Windows XP 64-bit and the graphics card (which I think may be the issue) is an Asus GTS250 DK/HTDI/1GD3 (Details from it's box).

Answer:No signal to monitor

Video input problems can be caused by many things, but to me it just sounds like your graphics card died.

To identify the problem (I assume the computer still 'starts'), please tell me:

Do the monitors work on another computer?

Do you have a computer in which you can try the graphics card? If so, please do and share the results.

Have you had any heat related problems before?

Does your motherboard produce any beeps on startup?

Heat crashes mostly happen during long gaming-sessions, or when the computer is on for a long time.

If the motherboard produces (a) beep(s) on startup, see this for info on the problem.
If the monitor(s) work on another pc, they obviously aren't the problem.
If the graphics card works on another pc, there's probably something else that has died, like the cpu.

I hopes this helps you along (if still necessary ofcourse)

Andy!

Answer:Help! No signal on monitor!

a problem with the graphics card, or the cable to the monitor. (In my experience, the cable is the likely culprit!)I'm assuming you don't even get to see the BIOS stuff doing it's check during startup??The easiest thing would be to see if you can borrow/swap a monitor and a cable. If you still can't see anything it suggests the grahics card is where the problem lies.The process of changing a grahics card is quite easy... providing you do actually have a seperate card and not "onboard" graphics, (which is where the graphics card is built into the motherboard).See if you can arrange a temporary swap first, and report back.Good luck,Regards,simsy

Answer:No signal to monitor

First thing I would do, is (if you have not had this pc on and working before) check which video output socket that your monitor is plugged into.
Is the pc using integrated graphics, or does it have a separate graphics card?
Be sure you have monitor attached to the correct socket, i.e. for integrated graphics you use the motherboard blue VGA socket.
It's possible if there was a previous owner, they used a different setup to what you expect.

HDMI input on my TV/Monitor showed no signal during boot. Typed my password in without a picture, waited until the tower was finished working then cut power. Rebooted and all was well. Anyone have an idea what happened here? I've seen it once before as well. Is it akin to how sound sometimes doesn't work after a boot? (Had that problem more than a few times.)

Thanks as always.

Question: Monitor No Signal

I have tried searching for how to fix this problem but wasn't able to come up with anything. I am not computer illiterate but also not a whiz at this. I am getting a no signal on my monitor which was working before I tried to upgrade my cd-rom to a dvd-rom. I have tried the montior on 2 PC's with the same effect. I know the PC's are booting up as I can hear the start "music" from Windows booting up. The monitor had been changing to a weird sort of blue color for the last several months. Is it likely that now the monitor has just given up or should I be trying something else? I hate to spend the money on a new monitor if that is not the issue. The monitor is an LCD ProView and is only about 3 years old. Thanksf for any help you can provide.

Answer:Monitor No Signal

Make sure your connections are tight. To your PC and monitor.

Could be your inverter going bad. Try shining a flashlight at the screen, at a 45* angle. If you can see the desktop, you need a new backlight.

My computer specs are as follows

12gb DDR3 corsair RAM
Intel i7 2.6 ghz
750 gb HD
1000 watt modular PSU
2 nVidia GTX 260's running in SLI

The issue I'm having is my monitor is not receiving a signal from the graphics card, which leads me to think that the gpu is damaged. However the power to the gpu itself is working fine. I have also tried taking the cards out of SLI and just using them separately including swapping the cards places. Nothing...

I then tried removing components that may directly effect the gpu such as the ram and other peripherals, I cleaned and inspected each and replaced them into their slots, still no luck.

The only thing I have not done is remove the CPU or use compressed air to clean out the pci-e slot, I will be trying the compressed air, however I don't see it as a likely solution so I am posting for some help.

The reason I believe that it may be an issue other that my graphics is because I would think it likely that both my graphics cards would fail at the same time, especially when the computer was running just fine minuets before the monitor lost signal and powered off

I've tried various other small things such as remove the battery from the mobo, switch dvi cables, all connections tight on my modular PSU, I have had similar issues in the past, however they seemed to fix themselves faster than I was able to troubleshoot the problem.

So it may still work on its own, however unlikely. Or I have a faulty component, either m... Read more

Im having a slight problem with my computer, heres the run down:

i turn on the computer as one would normally do, i then turn on the monitor (green light on), i get "no signal" shown on the monitor before it goes blank (light changes to orange). The computer continues to go as though it was going normally (all the same sounds, keyboard lights show up at the usual time) but nothing shows on screen. i then turn it off.

i repeat the process of turning it on and off when nothing is happening, until after several repeats it starts perfectly, with no errors.

once its on, and the screen working, there are no problems at all, it continues to run as normal (i'm using the same computer to write this post now after repeating the initial process many times)

I have tried the monitor, cable and power cord for monitor all on a different computer and they work fine. ive also tried plugging the monitor into the motherboard slot (rather than the graphics card slot) and it still doesnt work.

the computer had been working fine before this started. Also the problem only seems to happen when i cold boot. Also i dont have to repeat the top process as many times if i have only just turned it off when trying to turn it back on (maybe something to do with the temperature with it being on for a while before hand).

Any help would be appreciated. Not an urgent problem as it gets working eventually, just annoying, especially if im in a hurry to do something.

That means that i get the led from Mobo,led from GPU,all 6 fans are working perfectly and even the led on RAM's is on so that means that my RAM's should be fine isnt it? Anyway. No beep,no nothing and no signal. Do you know what is that supposed to mean? Im really dissapointed because i gave already 900 euros for all this and i get nothing from the pc. By the way the monitor's led works fine as well but no signal at all.

Ok I went on vacation for a week came back and my PSU was fried. Powered on for about 10-30secs then killed the boot up sequence. No big deal $150 and almost an extra 200W of power later I have a new 750W PSU installed awesome all problems fixed! Not exactly. I go to boot up my computer after plugging everything in and everything fires on like it should minus my VCs aren't outputting any signal. I have 2 EVGA 8800GTS and both are plugged in just fine but no signal from any of the 4 outputs. So my computer stays on as it should but I'm getting no output signal what so ever. Thought it kinda curious that the problem would flip flop on me after I install the new better stronger PSU. Any tips would be appreciated.

Answer:No Signal to the Monitor

Try one video card at a time, in other words, remove one and try it then remove the other and reinstall the first one and try it. If you have on board video, try that. Double check that EVERYTHING is connected properly to both power and data cables. Double check the memory sticks: remove 'em and reinstall 'em... clear the CMOS while your at it.... oh yeah, be sure to unplug the power cord from the PSU every time you start pulling cards and jumpering jumpers and checking cables and such....
Good luck!

Ok I bought a computer off ebay which came with a P5VD2-MX-SE MoBo. It hard an external PCI-E GFX Card (Can't remember model) NVIDIA I do believe. Since I've had this computer it repeatedly crashed at random times/Applications crashed (with the windows reporting error) and randomley froze.

I managed to narrow this problem down to the graphics port on the actual mobo been the problem due to onboard graphics working perfectly when I used that, the graphics card itself worked perfectly in another computer and I purchased a new graphics card EAH3650 I think, and the thing still crashed etc. Occassionally it would say the VPU had to reset or something because it failed to respond to commands (when I was using the PC)

A month or so ago I had problems I think it was that the monitor would display anything OR it wouldn't get past the Windows Loading screen and finally I removed the secondary RAM stick and the computer started working fine again.

My desktop posts fine, one beep as usual, keyboard light blinks once, optical drives check for inserted media, and the hard drive chitters away for the usual peiod of time until it gets to the log on waiting for my input which obviously I cant see at the moment. I normally have the monitor connected to the grafics card using the digital connector, but have tried the DSUB connector too (monitor supports both - ViewSonic VX24 (I think that model number is correct but not sure) LCD) with no joy on the desktop.

Hello. I bought a new PC today, everything went fine when i connected it up to the point where i needed to connect the monitor. I didn't get any signal, everything was connected correctly. Then, while taking a closer look at my old pc (using it right now) I realized the problem. My monitor only got a signal when the VGA was connected to a lower socket, Which the new PC case lack. I know, it may seem a bit idiotic, but, that's how it is. now.

Answer:Can't get signal from monitor.

When there are 2 vga sockets it means that there is the onboard graphics (built into the motherboard and can't be removed) and the other vga socket is from a separate graphics card that is plugged into the motherboard and can be taken out - and replaced with a new updated graphic card that has been purchased.
Were there any messages on the monitor? Did it say 'no signal' or somesuch?
Which pc have you got and what are the connections on back for graphics? is there VGA (blue socket), DVI, HDMI ??
And on the back of the monitor what connection ports are there? has monitor only the vga?

Good Evening!

I was wondering if you fine folks could help me out with a no signal issue I am having to my monitor.

It's a recently put together rig that I built on my own. The issue is that calling me an amateur would be a compliment and I really can't troubleshoot on my own. So when I ran into a problem, I was literally clueless. But the rig is brand new, I haven't even been able to install an OS yet because I can't get any image up on my monitor.

I've already replaced the motherboard and everything else seems to be booting up just fine. The heat sink is running smoothly, the video card boots up and seems to be running fine. I've checked for loose screws in the case, tried putting the video card in other available slots, tried removing a stick (and both) of RAM before booting. A few other things I have tried but don't remember them off the top of my head.

Anyway, my components, if they are needed....

that power supply sux. It's not even in the approved list for power supplies for that video card, you'll need a 650W at minimum and a name brand with a good reputation. I can not say that is the main problem, but it is contributing to your problem.

Here is a list of approved power supplies for your video card from AMD

A method that can help you determine your issue is removing the board from the case, then pull everything off the is not required to get it to post (Power On Self's usually the screen you see just before windows starts)
Just leave the cpu/fan/heatsink, video card, mouse/keyboard, one stick of memory and properly connected power supply of good standing. Place the board on a non-conductive surface and test it out to see if it'll post

A few weeks ago there was a power surge that killed my old PSU. I just got a new one today, I put it in, and now my monitor isn't recieving a signal. It's not the monitor because the monitor works fine with another computer. When I turn the computer on, everything else seems to be turning on right, it makes the beep noise that it's supposed to when it starts, and the video card is running as well. The new PSU is 500w, same as my old one. I even tried unplugging and starting again, or turning off and on the PSU switch, but that didn't do anything either. Anyone have any idea what the problem could be?

Answer:Monitor has no signal with new PSU

maybe the surge did something to your graphics card too? It's not likely, since there would usually be some sort of beep code at POST. However, i stress the word "usually" because it's still possible. Try changing the graphics card, or if the card is integrated into the board, get a PCI card.

If you currently have an AGP card in it, test it with another AGP card.

If you currently have a PCI card, or integrated graphics, then test it with a PCI card. With many computers, if a computer is set to start on the integrated controller, it will ignore the AGP card until you change the settings in the BIOS. It will, however, see the PCI card and use it instead of the integrated controller. (I'm almost certain about this, but almost isn't completely)

Answer:No signal to monitor

Check that the monitor cables are correctly and firmly inserted first - if this isn't the answer, then check the graphics card for proper seating.

My setup is currently a 1280x1024-1920x1080-1920x1080, the small monitor is an acer and the two big ones are both asus. So recently i have had the problem that the monitor on the far right keeps losing signal, it turns black for a few seconds, then it comes back on and the HDMI source logo thing comes up on the page. It happens a few times in a minute then it stops for a while then it usually comes back.

If there is anymore information i can provide then please say so.

I have a second monitor plugged into my computer. I'm using the first one just fine, but my scond one isn't detecting anything at all. I should note that I use this:
My card is one from the Intel 4800 series, powerul, but old. Can someone help me troubleshoot?

Answer:I have a second monitor, but no signal.

Hello and welcome Instant mate have you updated the driver for the card? I cannot find a driver for it and I suspect this is an age related problem.

Also mate we need some system specs to work with as you have listed the OS as California and I am guessing it is Windows 7 of some version. So please let us know the specs.

I'm getting no signal when I connect my monitor. The port is connected to a ribbon and then connected to motherboard. I have tired disconnecting the ribbon on reconnecting. I was not having any issues with the monitor before I disconnected it and reconnected it.

Could it be the ribbon that is bad or am I looking a bigger problems?

Hi, I recently bught a 1GB memory of RAM for my PC.

I went to a website and it did a system check and told me what RAM I need. I got one (DDR2 3400) off the net, and plugged it in.

I have 512 mb instlaled so I wanted an extra 1GB with 3 spare memory slots (4GB in RAM in total available)

When the RAM is connected the monitor doesnt recieve a signal - but when i take the new RAM out the computer works fine?

I have read that problems could be with power supply. Is their anyway of getting it working, or will i need to get a different sort of RAM?

Hey there I'm sure you have dealt with plenty of this but I've tried everything I can think of to get my new build to at least show video. This is my new rig:

Video Card: GIGABYTE GV-R465OC-1GI Radeon HD 4650
Ram: OCZ Gold 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800)
Hard Drive: Western Digital Caviar Green WD10EARS 1TB 5400 RPM
Mother Board: ASRock M3A770DE AM3 AMD 770 ATX
CPU: AMD Athlon II X4 630 Propus 2.8GHz

Now the problem is that I had plugged an old monitor into the vga slot on the video card but I don't get a signal to the monitor although everything else including the graphic cards fan is running fine. Please if anyone can help I would be greatful. Also let me know what you think of the rig. Thanks.

I am having trouble with my pc starting up, yesterday i went to turn it on and got no signal to the monitor although i can hear it boot up and makes sound from windows start up but no signal was detected on both my monitors, the graphics card fan is running extremely loud so i thought it might be that,
so i switched to an older card and that seemed to boot up fine but was told it was running lower since not enough power was getting to the card,
my current card is a 9800gtx+ and it requires 2 separate power connections my older card doesn't so it's less power hungry by a long shot.

so where is the problem lying would you suspect my mobo is toast or the psu?
it's not a new pc btw has been running fine for 2 years and psu is more than capable of running it.

Answer:No signal to monitor

Hi kitaz.

If your system works fine with your older card, then your motherboard is not "toast". What are the specs of your older card? Also, what PSU are you presently using? Also ensure that both power connectors are plugged into the GPU.

Before putting in the 9800GTX did you uninstall all previous graphics drivers?

I have the problem that my monitor sometimes does not recieve a signal. It appears that the computer has powered up and i can hear the PC working and all the mouse and keyboard lights are up and running. I have switched monitors and sometimes the second monitor will work fine, sometimes not. Sometimes rebooting works, sometimes not. I haven't changed the system physically in any way eg. added RAM etc. I removed the extra cards and vaccummed them. Thought i had solved the issue. But now a month later it has started happening again. I suppose i would like to deal with this situation whilst i can still use the computer and access the internet and before it stops, maybe, completely? I did hear, i think, one long peep on booting up. It just caught me by suprise and sounded different than normal. Oh! and when my daughter was using it the other day, it just blanked out and there was no signal.Thanks

On my daughters Acer Aspire T310-3970 Celeron D335, she suddenly found "no signal" to her monitor, after a complete freeze. She rebooted, but after that she got no video to her monitor. She is using on-board graphics.I thought it would be a simple case of fitting an ASUS PCI graphic card I have, but no signal from that either. The graphics card works fine on my other old PC.Switching on the PC, I don't hear the hard drive clicking into action now, with no associated flashing HDD light. Does that sound like a power supply problem, or could it be she's accidentally changed some settings or other? Help!!!

Hi - hope someone can help! My son has a problem with his PC. He was using it one day, when it crashed. He started it up again, thinking it would come on ok, but it didn't and he got a message on the screen "No signal". He has checked that the cables are all securely fixed, but it has made no difference. Any suggestions for what else he might try?

My problem is that I have an ASROCK K7VT4A+ mobo and an AMD Sempron 2600 cpu from which i get no signal from the agp.

I have an LC235 atx 240W psu in the tower and a 64MB agp graphics card.

Could it be either the psu is not powerful enough for the mobo or the agp port which is goosed (I hope not)?.

Recently i've attempted for the first time to build a computer, but i've had several problems and am afraid that I will never get it to work.
My problem is after I install the parts to the motherboard and power up the motherboard and CPU I get "No Signal" on the monitor.
I have litterally tried every solution to fix this problem the the problem still exists.

These are some of the solutions I have tried so far
. Build outside of the case
. Keep the essential parts on to test ( CPU + Fan, 1 Stick of Ram, Graphic Card )
. Tried to use the onboard graphics ( Taken the graphic card out for meantime )
. Tested the ram in different ram slots
. Clearing CMOS

Just to add that I have had 2 motherboards, 2 CPU's and 2 kinds of 4GB ram, since I was convinced they were the ones faulty but obviously they weren't ( Replacement for the 1st CPU and a refund for the the 1st motherboard then got a different motherboard, DDR2 ram for first motherboard then I got DDR3 for the next motherboard )

Here are the specs:
( Original Motherboard ) Sapphire PC-AM2RS790GX Socket AM2+
( Orginal RAM ) Corsair DDR2 4GB RAM
( Current Motherboard ) Asus M4A79T-E Socket AM3
( Current RAM ) Corsair DDR3 4GB RAM
AMD Phenom II x3 720 ( Socket AM3 )
Corsair 750W PSU
Asus HD 4870

So far I have tested 2 motherboards and 2 of the Phenom 720's but still the fault exists.

I have asked around on some other forums but I have had useless answers which did not fix the problem, I saw th... Read more

So last night before I went to bed I was on my computer everything was working fine. I come back to use it this morning and my monitors aren't doing anything. The lights are blinking as if they are in sleep mode or something. I have tried plugging the monitors in to my laptop and they both work fine. I have tried another video card in my computer and nothing showed up with that one either. I got it to start up and had signal a few times but now don't seem to be having any luck at all. I also tried putting the video card in to the second slot that I have and that didn't work either. Would this be a motherboard issue or maybe a power supply issue? I'm running out of ideas here.

Thank you for any help!
