I posted earlier about this Powerleap not holding cpu settings... and it was the error control not working... but now, the computer locks after about 5-10min in winxp. I changed the multiplier to x11 instead of x12 and it still locks but after 10-15min. Is the CPU overheating? Powerleap advertised it at 1.2ghz when replacing a 300a. We have a full tower case with plenty of fans. The other components are a Creative TNT vid card, SB Live, 2 sticks of pc133 256mb ram and 1 stick of (i guess pc100) 128mb ram, 8gig WD hard drive, 40gig Maxtor hard drive, yamaha 20x cdrw, creative 48x cdrom, and.... I think that is it. Could it be the pc100 ram? or the vid card? Also, what exactly should the bios settings be set to on that abit bh6? Like the user defined cpu settings, the ram settings, etc...
