Been running beautifully since I gut my old tower and put this stuff in a couple years back until tonight. I use it primarily for media and the occasional game or two and I consider myself somewhat tech savvy enough to troubleshoot software problems but I'm stuck on this one, which I believe is a hardware issue.
As of this evening it crashes in any game that I boot up using 3D graphics (for example Bioshock 2, Europa Universalis III). Initially it runs fine in the menus but as soon as I try to actually delve into the game where the heavier stuff is being rendered it causes the game to freeze, twitch all kinds of colours in the background, glitch the sound (inside the game or from other programs running) and lock-up the system altogether requiring me to manually turn off the PC. For older 2D games it seems to run normally throughout, for example I tested good old Diablo 2 on it and it seems to be doing fine.
Could it possibly be the Power Supply? it's about 5 or so years old now and predates the current set up I've put into the tower. Essentially everything has been replaced (disc drives, HDD's as well). But all these changes were done over a year ago and have been working fine.
Could it possibly be the GPU? Is it just dying on me?
All software/drivers are up to date for the system and outside the horrible crash it experiences in these games it runs everything else perfectly fine. I'm even writing this post with this PC at this moment.
