Huge stuttering problem with new computer
Alright, so I recently bought and put together a new computer. Here are the specs.
Sapphire 4870 512mb
Biostar TP45HP Mobo
Vista Ultimate 64
OCZ Ram 2x2gb
Corsair 550w PSU
Samsung DVD Burner
The main problem I'm having is a HUGE stutter with the games I've tried (Oblivion and Bioshock). There isn't constant stuttering, just one large stutter that lasts for about 30 seconds and occurs quite frequently in my games to the point where they are unplayable. I O/Ced the processor to 3.4ghz last night, and ran Prime95 overnight. No errors, everything stable. I just flashed my mobo to the latest bios from the website as well, although I believe I was already up to date.
Are there any known issues of this happening with any of these particular components? I've dialed back everything to default values in the BIOS, stutter still happens. Looking for any help at all, thanks guys.
