GPU fan randomly speeds up and down?

post #1 of 3
Thread Starter 
I just installed a Geforce GTS 250 in an HP machine I had. Upgraded the PSU to 600 Watts, and put in the GPU and the fan revs up and down on boot constantly, and nothing displays...anyone ever deal with this? The onboard is still working I changed the default video to PCI X16...once vista re-installs and I can get in I'll see if Windows even sees the card in the device manager. It's an GX626aa#aba part number. Thanks guys thumb.gif

Hi Tang87. Does the graphics card get detected after the Windows reinstall? What card was in the system before the GTS 250? Sounds like a power issue to me, so go through the system ensuring all power cables are connected and nothing is loose.

I got to windows and the GPU wasn't even detected. I shut down and re-seated the card and used the other PCI Express cable from the psu still no picture. Then I tried a gt520 I had laying around with the VGA and it worked. Then I wondered if it was the DVI to VGA I was using for the crappy monitor at work I have. I moved the machine to a DVI connection (DVI-D) and I got picture. I don't know if the card didn't detect a connection so never initialized or what, but now I see it in windows. I restored the Vista installation with the 2006 version so I'm going through the millions of updates for windows now, but appears to be working. Still getting really bad framerates on Diablo 3, but I knew it wasn't going to be phenomenal of a videocard. Half tempted to use it just for Physx in my computer and get a higher end GPU for this one. This was the weirdest video card issue I think I've had so far...
