I built this system about a year ago and I have had this problem since the beginning. I have a ATI Radeon HD 4850 by MSI I don't think they make it anymore, all I know is that it had a special heatsink. It was an open box product bought from Newegg, and I can't find it there anymore either. It works well and doesn't heat up too bad (I can't tell you idle/load temps). I'm running windows Vista 64 (OEM for sys. builders), 8GB of RAM, 1TB of memory (2x500 GB).
I have a problem running all kinds of games:
and a couple others that are just freeware
My question is, Why won't these games work? Is it my video card? Is it a DirectX issue? Is it Windows Vista?
*don't do that until you specify how the games are not working exactly*
The games all launch perfectly, but after I start playing for about 5 minutes the screen does one of two things:
-Or goes gray
I don't know the significance of that
also, I used CCC (Catalyst Control Center) to turn my GPU's fan to 100%, also I used the software you recommended and my idle temp is 55C and my load temp is (I don't know if this is right, but) 106C. Not unless I read the graph wrong.
