Well I got a Geforce 7800 GS, 650W PSU, and an extra 512 MB of ram to run Oblivion, since my 5200FX wasn't cutting it, and needed the extra juice for the 7800. Anyway, Oblivion froze, in a manner of freezing I never seen before. It cut the video signal and sound, the monitor light went from green to orange, yet the PC still seemed to be running fine. However, I wasn't able to do anything since I couldn't see anything, so I had to hard reset the PC. I was running with 84.21 drivers. I upgraded to some beta drivers of 84.40 and now Oblivion runs no problems, I played 10 hours in a row one day and it ran fine, no problems, and no freezing. My other games are now having this issue though (Sims 2, VTM: Bloodlines, Doom 3, Civilization 4, etc.) where after playing for a while, they freeze in the exact same manner as above. Everywhere I read suggested the PC is overheating but the fans are running great on everything (checked with case off) and I cleaned out all the dust from the case. Somebody told me that I needed to upgrade drivers, bios and firmware, and I have, but I haven't run any games since I did, so I dunno if it fixes the problem or not, haven't really had time to run games recently but will soon. Anything else I should make sure to do before resuming gaming? Anybody else know of solutions to this kind of problem? And on a related note, if it is overheating, will a PCI Slot Fan placed next to the graphics card be a good idea or what?
