Computer Won't Load Win98, etc

[.]

System:

P4 1.6GHz Intel
Intel D845WN Motherboard
256M RAM
Radeon 7000 64M TVO
Sony CD-RW
Segate 40G HD

System originally ran Win98SE. Guy who had it before me tried to
upgrade to Win XP when problems started. He said that when the machine
went to reboot during the upgrade, it would go no more. kept reporting
errors with the setup. He took it in to "Geeks To The Rescue" who
ended up putting in a new Motherboard. After that they got it to run
and u/g'ed the OS to XP. It ran fine for about 4 weeks or so, then
started rebooting itself, never fully loading into XP.

I've reformatted the HD to FAT32 and tried to load Win98 SE, but the
setup routine cannot load the installation files, let alone go any
further. Keeps reporting that "SUWIN has caused an error." Even tried
loading DOS 6.2, then u'g'ing to win98SE and keep getting the same
error (DOS 6.2 runs fine).

I've disconnected everything except the FD and HD, taken out the video
card and used an old Promise PCI card, swapped RAM sticks and power
supplies with ones I know that work fine in other systems swapped
HD's. I've updated the BIOS and disabled everything except what's
absolutly need, yet nothing I do will let load anything newer than the
old DOS OS.

Does anyone have any ideas, as I'm fresh out.

Thanks for any help anyone can provide.

Does it give an error number or mention a filename ? (e.g. "suwin has caused
an error in filename.xyz")
Are you overclocking ? (even if you're not, try lowering the FSB as low as
it goes, and running setup)

Also try slowing the memory (if it's running at CAS2, lower it to CAS3, etc)

SUWIN gives various error numbers, seemed to be different everytime I
tried.

Not overclocking, but I'll look into changing the CPU/memory timings
anyway.

Thanks.
