***All links lead either to the products page or the newegg page of said product. I've had serious issues with my computer but have no idea what's causing it. My original setup consisted of the following: XFX 680i LGA 775 MB http://www.newegg.com/Product/Product.aspx?Item=N82E16813141003 Intel Core 2 Duo E6550 http://www.newegg.com/Product/Product.aspx?Item=N82E16819115030 2 Gig sticks of Corsair Memory 1066 PC8500http://www.newegg.com/Product/Product.aspx?Item=N82E16820145043 EVGA GeForce 8800 GTS 320MB Video Card http://www.newegg.com/Product/Product.aspx?Item=N82E16814130038 WD Caviar 80GB HD http://www.newegg.com/Product/Product.aspx?Item=N82E16822144102 ASUS Optical Drive http://www.newegg.com/Product/Product.aspx?Item=N82E16827135156 BFG 650W Power Supply http://www.newegg.com/Product/Product.aspx?Item=N82E16817702003 After putting this rig together it lasted about 4 or 5 months before I started getting crashes and video glitches whenever I played a video game or tried watching video. I assumed it was my video card. Actually I ended up assuming a lot. The only I actually had go bad that I knew was the RAM. To make a long story short I RMA'ed a whole buncha crap. My video card, MB, and RAM. I replaced the HD with a confirmed good one. I tested the PSU with this: Rexus Digital Power Supply Tester http://www.newegg.com/Product/Product.aspx?Item=N82E16899705003 Everything came up green. The only thing I didn't replace/test was the CPU. Well after RMA'ing everything getting it all back I assembled it and everything was working fine for about three months. All RMA's resulted me in getting the same product back except for the motherboard which actually got upgraded to: XFX 780i SLI MB http://www.newegg.com/Product/Product.aspx?Item=N82E16813141005&Tpk=XFX%2b780I And now I'm getting the same issues. I can surf the web all day, check my email, etc. But the moment I try to play WoW, Simcity 4, Doom 3, or Supreme Commander my computer crashes. I just ran Memtest and it came up with a error. So now I'm assuming my RAM is going bad again. The only thing I can think of is that maybe my PSU tests good but under load it gives the RAM too much juice and starts to fry it. Is that even possible?! I'm kinda shooting in the dark. Last symptom I get is after a crash, I do a restart and the computer boots in BIOS safe mode. Yes, I have reinstalled drivers.....multiple times. (Even used Driver Cleaner Pro in Safe Mode.) Yes, I tried with a fresh copy of windows. Yes, I have flashed the BIOS. No, this isn't my first computer I've built. Built my wife's and its working fine. She can play WoW all day.......grrrr. BTW, using Windows XP SP3.
