Hello community, I have been experiencing a ridiculous amount of crashes in video games where the screen will simply freeze and go black or a random color with a glitchy sound playing endless in the background until I restart. This has persisted from the moment I upgraded to 8 gigs of ram from 4 that I originally had. However, these crashes would only occur during gaming so I had first assumed I had a video card problem. After RMAing my video card and getting a brand new one, I experienced the same crashes. More recently, my computer actually had a BSOD crash during gaming. A second BSOD crash followed up after I restarted my computer, and this time it happened while only using AIM. I removed 2 of my 2gig sticks of ram, and everything seems to be working fine now. I am okay now as long as my computer does not continue crashing, but would there be a reason why I would not be able to use 8 gigs of ram? I am using a QuadCore at 2.66ghz stock speed 6mb cache, 4(previously 8) gigs of OCZ ram (4x2gb sticks), an XFX GTX 260 black edition, and Windows 7 Ultimate 64-bit. My motherboard is an XFX 750i. Any suggestions or help would be appreciated!
