The other day I replaced the CPU fan and heat sink in my computer because the fan was rather noisy. It was not overheating or anything, it was just a noise issue. After replacing it, I started having problems with my display. It would blank out once for a few seconds after the Windows startup screen and then again after logging in. At this time I would see an error saying that the display driver was not responding, then shortly after the monitor would go blank for good. The PC appeared to be running, but there was nothing I could do to get the display up.
I went into safe mode and removed the drivers, which were already current, and reinstalled using a clean installation. No fix. I located a Microsoft support article, http://support.microsoft.com/kb/2665946
and that didn’t work either. I swapped out power supply cords and even tried a known working video card (9800 GTX+) and the result was the same. Completely removing it and using the onboard video worked fine. My temps were all good and otherwise everything looked to be in order. Then I tried moving the card from the PCI-e x16 to the x4 slot. Works perfectly. I tried switching it back and the problem came back again.
I assume that the slot is damaged. I am wondering what kind of a performance hit I will see in games now, and could this be the start of a mobo going bad? I am saving for an upgrade, but it won’t be until early next year so I am hoping that maybe it can hold out for that long so I don’t have to spend on a new board in the meantime.
