hi all, this being my first post hopefully you all can help me. The problem: BFG Technologies Geforce FX 5700 OC 256mb (card is OC from factory) http://www.bfgtech.com/5700OC_redux.html my system: Processor: AMD Sempron 2500+ 1.75GHZ MOBO: MSI mainboard with via chipset Model# KM400A Memory: 1gb(2 sticks) of PC3200 400mhz Power source: Antec 430w true power Hard drive: Seagate 7200rpm 60gb Sound: SB Live X-Gamer 5.1 I have a Card cooler on the video card (the twin fan thing held in place by a pci slot, no connectors to PCI slot runs of PS lead) I have 2-4" case fans, processor fan. Problem: Playing World of Warcraft causes the entire computer to completely lock up after about 30 mins-1hr of gameplay. This lockup is reproducable with any graphics intensive game i have. (including C&C Generals) I have been through 7 RMA's with BFG. the 5700 was an upgrade from my Ti4200 (which worked perfectly except that the fan stopped working every 6 months and required a new RMA to fix the fan, hence the upgrade) the lockup dosent give a Blue screen or any errors it simply freezes everything and the in game sounds stutter and replay then stutter again. but the mouse, keyboard etc... are all frozen. The 3 5700's BFG has tried with me ALL have had the same problem. Any ideas?
