Thread: Video Card Blues | Forums

  1. #1
    Gentlemen, it has been a while since my last visit here, but now I find myself again in dire need of your help. I have not been gaming on a regular basis for a couple of years, save for some occasional gunnery practice with the QMB.

    Now, the other day I was having a session of just that when, alas, my trusty old 9800 Pro card, which had served me so well since the dinosaurs walked the earth, suddenly gave up and passed away peacefully, old and full of days. Fortunately, I had an old card that I could use for surfing and using office programs.

    So, I went shopping for a new card but since I'm still running AGP, the options were limited, but I found a nice Inno3d 7600 GS card that would suit my needs and not break the budget. I plugged it in, booted up and prepared to install the drivers. Then all hell broke loose.

    In short, the problem is that the screen goes blank at random times with the monitor LED blinking. It's like it doesn't get any signal from the computer, like when you forget to turn off the monitor after you've shut down the PC. This happens very often, and sometimes the signal doesn't come back, and I have to reboot.

    This happens regardless of which video and mobo drivers I'm using, but all the time when the rig is under load: boot-up, running antivirus or IL2, for example. It even happens without any drivers installed. There have been no artifacts and no crashes whatsoever. This leads me to believe that it must be a hardware issue.

    I suspect one of two things: It could simply be that the card is faulty and shuts off for some reason. Against this is that there are no gfx errors at all. The other thing, which I think is more plausible, is that my rig could be underpowered with the new GPU installed. IIRC, my PSU should deliver 18a on the 12v rail, and that might not be enough. It's 2-3 years old, mind you, so it could be spitting out even less.

    I trust the collective wisdom of this community and need your opinions on the matter. Thank you for your time.

    Regards.

    could be underpowered
    It could very well be... in my opinion...

    Are you sure the power lead to the card is connected correctly? Maybe try a different lead from the PSU?

    Good Luck!

    And I agree also, re the power situation.

    It would be good to know, though, what you did about the ATI drivers that you had for the 9800 Pro? Removing them entirely involves more than just using the ATI Uninstall utility, especially If you've switched to nVidia.

    Thank you for your response. I tried different leads with the same result. With physical changes, I can only make it worse, and that's by closing the cabinet. Maybe the fans have to work harder then and draw even more juice from the 12v output. I don't know.

    About the ATI drivers, I uninstalled them (in safe mode) with the Windows Control Panel and then used Driver Cleaner Pro to get rid of the remains. Is there any more I should do regarding drivers? I still think it has to do with hardware.

    Your driver removal method was correct, so I doubt that is the issue. It could be that:

    1. your PSU cannot supply sufficient power to your new card.

    2. heat build up issue, either the card fan is not working correctly or cannot draw sufficiently cool air.

    3. bad video card.

    Which driver did you install for your 7600GS?

    I installed the 169.21 driver which I got from Nvidia's website. However, the blackouts occur even without any drivers installed, so I doubt it's driver-related.

    I think I'll take the chance and invest in a new and more powerful PSU. Do you think a 550w unit with 33a on the 12v rail would do?

    That will work fine. I use a 580 watt with my 7800GS, 2 extra fans, 2 HDD's & 2 optical drives.

    If it's in your budget it's never a bad idea to get a better psu in these situations. Even if it's not the solution a good psu can be carried over to a new rig and will save you a little at build time.

    Thank you all for your help. I will report back in a couple of days when I get the PSU.

    Got the PSU, but still no luck. Exactly the same thing happens. Must be a faulty card then. Anyone having any experience with poor quality control with Inno3d products?
