Hi all plz help if you can. My specs. mobo - Asus cusl2-c Intel 815 EP chipset cpu - Intel P3 1 Ghz ram - 2 x 128mb Kingmax video - 32mb Geforce 2 mx h/d - Quantum fireball 13 Gig cdrw - sony 32x8x4 sound - s/blaster live value I was running win98se with no probs. Went to upgrade to XP Pro with error: Stop - 0x0000007e (0xC0000005, 0x80845B83, 0xF9E853D8, 0xF9E850D8) Happens in same spot all the time. fdisked and reformatted to go back to win98se but new error comes up as : MSGSRV32 caused invalid page fault at kernel32.dll etc etc etc. (detecting h/ware and s/ware 18 minutes to go.) Funny thing is I can install win98 1st edition no probs. I've tried swapping h/drives vid cards and ram around with no luck. i saw a previous post with similar probs. I suspect my mobo but can ne1 confirm my worst nightmare. many thx in advance.
