What causes the video card failure?

  1. Hi guys,

    Im having trouble on my desktop for a week, one day when i turned on my pc, after running it for 30mins, the monitor turned black but the cpu has lights turned on. I reset it, then it asked me to open it on safemode or normal windows, i chose normal windows and it started. After a couple of minutes, the monitor turned black again. I've tried to turn off and on the monitor switch but it didn't help. So it makes me wonder what the problem is. I press the reset button again but I have a suspicion that it might be the monitor that has a problem. when the window started, I open my media player and play continuous songs, after a minute, it turned black again BUT the song continuously playing, then after a minute the song stoped! So im am sure t is not the monitor.

    I tried to open it in safemode to do some investigations, and it was not shutting down even for an hour. I made some diagnostic tests and all hardwares have passed. I've tried to re-seat the memory card and video card but when i run it in normal windows, same thing happened. I had a suspicion that it could be virus, so i reformat it 2days ago. after reformatting, same thing happened, but this time lines started to appear on the screen, the graphic looks weird, it almost have 8-color display on it. I've checked the video card in device manager, and it says it is not functioning. So my video card got broke.

    Now i am wondering, during the past few days, the graphics look good, but as i am trying to troubleshoot it myself again and again, the video card is now broken. As i remember 5 days ago, when i made a dell diagnostic test for hardware parts, everything has passed, but now it is saying that my video card is not functioning.

    Any idea that its really my video card got broken, or are there other hardwares mulfunctioning causing the problem and hit my video card? What causes the video card failure? I do pc gaming, I do 3d modeling, but i use my machine for an average of 4hrs a day.

    It was so dissapointing because my desktop is just 15mos old. It is Dell XPS 420, with nvidia geforce 8800gt 512mb ddr2. And unfortunately the warranty is expired.

    Any help would be really appreciated.

    Thanks in advance!

    Video card failures can happen by bad installation, power issues, or by dust dirt and general overheating.

    If you have integrated graphics on your mobo, you can always remove your video card and plug your monitor in to the alternative vga socket on the back of your pc. If your problem stops.. you have your answer.

    Is your case dusty at all, you say you've had it for 15 months. If you havnt checked it within that time your case temps could have risen causing the average temp of your components to increase, causing failures.

    So you've booted up in safe mode correct? Have you had any updates recently, maybe driver changes that may have been broken.

    Two things..

    Bad RAM (one module could go and you never know)
    Bad PSU (these always goes on you when you have issues)

    If the video card can work then on the next reboot don't work. Most of the times video cards just go quick. Nvidia Geforce I had 5 of them go on me not at the same time but they did go. Make sure next time that card is getting enough cooling and don't bother to over clock it either that shortens the life of it.

    Hi Guys!

    Thanks for your advices!

    I've checked the fan and memory, they are all fine.

    I can't say it has wrong driver because i just reformated it days ago, after reformatting, the windows started fine, but it crashed down again after a minute. Until now, it has a very bad graphics, the device can be detected but it has an error sign and i am sure that the video card has a problem.

    My fear is that my psu might be causing problem as well and it hit my video card and broke it. I am afraid that if I purchase a new video card, it might get hit again, IF my suspicion is correct.

    I'll see the technician tomorrow, then lets see what is really causing the problem. So if any of you might encounter the same situation as mine (hopefully not), we all know what to do :)

    Did you try to use the onboard graphics vga socket? If you have one of course.
    Remove your card first. This will answer all your questions.

    Good luck.

    Hi there,

    I dont think I have an onboard graphic.

    Anyway, I just got my desktop fixed, dell changed my graphic card, they said those encounters I had were symptoms of dying graphic card. They said, it might be the attached cooling system on the graphic card is not functioning... whatsoever.

    Thank you guys for your support! ;)
