Any Ideas on KT7 Problem?

[L3]

I have an Abit KT7 w/ latest Via 4in1 drivers. It sits on an UPS, but last night after some storms moved through (with system powered on) it began to act strangely. At power on or reset, it posts the processor speed and then hangs. It won't scan memory, won't let me into BIOS, it just locks. Repeated resets will eventually result in memory scan, whereupon I can access BIOS or let it proceed to boot. So far I have:

CLeared CMOS
Tried to post at processor default speed
Updated BIOS to ZT
Bumped core Volts to 1.85 (was 1.825)

Any suggestions would be much appreciated!

Bump for help

Whats your cpu speed? is it set to default or you overclocking it? Check you mem settings turn them down to see if that will help. Could be lots of things. If you not over clocking it you should use the default voltage setting for the cpu. But give some more info, CPU, mem, mem type (cas2 or 3 100mhz or 133) Harddrive, vid car, cd, sound any other.

OK, the details:

Duron 600 oc'd to 1 Ghz (tried default, no joy)
Memory was 384 MB, 1 256 MB Micron PC133 dimm, 1 128 MB Apacer PC133 dimm, running cas3
Norton Diagnostics said 256MB dimm bad, running just 128 MB now, still fails.
Radeon LE 32 MB hacked to Radeon 32 DDR
SoundBlaster Live Value
CenDyne 16x10x40 (TEAC) CD-RW flashed to 1.0B
No name 50x CD-ROM
WD 20 GB 7200 rpm ata66

Nothing has been changed in days, system has been rock stable for months!
Haven't had trouble, then all of a sudden...
Thanks in advance for any ideas

Try setting the mem to pc100 if you have not already. If the 256 craped out the 128 may not be in the best shape either. If set 100mhz already try moving mem to a different bank. your 256 133 may work at 100 again may. My best guess is its your mem running oc the way you are you need rock stable mem. Mem is cheap right now so if it's you mem won't cost you an arm and a leg. Good luck
