"When I had My DFI I Flashed a p BIOS means Performance. When i did that and came back into windows seemed i had some weird video stuff going on. EG. Once XP is Loaded under the "current BIOS" then U load up SLI drivers etc.. NOW heres the catch Freezing guyz, Cuz I just freezed also, lol Once U have a Loaded XP etc. with a BIOS and IF u FLASH OR CHANGE the PEG etc. then U WILL have a LOCK UP ... I just did like my main poster here. So the conclusion is Did u Flash or change BIOS setting WHILE yer vid drivers were loaded ? YES u have to do a CLEAN intall to fix the FREEZING, Seems the Newer BIOS's have major PCIE code upgrades. That Conflict with just like APIC or whatever. So If u Have Lock-UP's in SLI once a game LOADS then this is the KEY. BTW:1007-004 will NOT load a clean isnstall of XP with RAID0 as main. nice bug it has.
