First off, let me post the system spec for you all... AMD64 3500 clawhammer core MSI K8N Neo2 Platinum 2x Patriot 512mb PC3200 RAM at 188.8.131.52 timmings BFG 6800OC 128mb SB Audigy2 ZS WD 80GB SATA Maxtor 120GB PATA Antec Truepower 430 WinXP Pro SP2 Now onto the problem. I had been using the BFG card in my system for about a month with no problems whatsever. I upgraded the fan assembly on the card to a Zalman VF700-CU to help the card run a bit cooler and to quiet down the noise. I installed the Zalman unit as instructed and gave my system a quick run through to make sure everything was working correct as I was taking this system to a huge LAN party that same day. Well, everything ran fine so I packed up my system and went to the LAN party. When I set up my system at the LAN party my graphics seemed to be causing major system instability. CS:S would work for about an hour before I would get graphical glitches and my system would either freeze up or I would get the BSOD. BattleField 2 did the exact same thing. Well, after the LAN I plopped in my old tried and true ATi 9800pro. I cleaned all the Nvidia video drivers and installed the Catalyst drivers. Now, my system tends to do the same glitching/freezing/BSOD thing with my 9800pro! To top it off, now whenever I play BF2 I get polygons that stretch and glitch out on moving objects. The HUD even disappears from time to time. I've tried reinstalling BF2, Steam and HL2 and those didn't work. When I was moving the computer to the LAN party it did get jossled around a little bit, but nothing harsh like banging into anything. Could this have causing my motherboard to get damaged? Could a damaged AGP port be causing this problem? I would greatly appreciate any help with this. Thank you!
