Random kernel 32 dll errors

I have a computer that I have been working on for a relative. it is a P 200 with 96 meg of ram 8 gig hd and a tyan mobo.... she started getting alot of errors with it so we decited to reinstall ME I fdisked and formatted the drive. and windows found all of out hardware fine.... set up the nic for the cable modem and sent it back to her.... well i get a call tonight she is getting kernel 32 dll errors like mad... some will just randomly appear when she isnt even near the computer... mostly kernel 32 dll errors in msinm and word pad mfc42.dll errors... a am beginning to suspect some hard ware failure but not quite sure where to begin. i am thinking a power supply may not be up to snuff..but not sure.... it is an older at board with the 72 pin ram Thanks in advance

Actually I would think the RAM is bad (getting overheated etc..)

try this
http://www.tweakfiles.com/cgi-bin/dl...docmem1_45.exe

it will create a bootable Floppy that will check the RAM.

Sounds like Overheating. Random errors or blue screens is a result of overheating. check heatsinks etc.
