Hello and thank you for your time, I have just done a basic overhaul on my pc. I have slapped in a biostar m7viz km400 ddr v/s/l/sata, athalon xp 3000+ 333 fsb oem 512k, zalman cu-flower socket a/7/370, kingston kvr 512mb pc3200 cl3,radeon 9800 pro 128mb ddr crt/dvi/tv and a 5.25" dual fan bay system cooler. and now to my problem I tried running 3dmark and some pc games and my computer will now shut itslef off and not allow me to turn it back on for a few minutes.. a few people have said it was a driver issue so i replaced the driver MSI game me with the one form the ATI site.. that appeared to fix the problem as i got through a full test of 3dmark without my pc shutting down.. then today i play "Vegas Tycoon" for a few hours and my computer shuts itself down again. A few other people say it may have been an overheating problem so i installed a program called speedfan and here are those results http://www.emuxhaven.net/forum/index.php?showtopic=4679&st=15&#entry56317 so if anyone could help me with this i would really be appreciative.. also on another subject the processor is only running at 2.16 shouldnt it be at 2.5?? i switched the jumpers on the motherboard to the 3rd row at 166 just as the manual said , is there something else i missed?
