I have an AMD k6-2 450 Mhz system ,with 32 MB ram and 8.4gb HDD. It all started a few days ago when the system suddenly crashed and when restarted it went to scanreg and repaired. Then again after a few hours it crashed and the crash was VMM page fault at ...! I checked for signs of any trouble and nothing. NO changed files, no registry errors. nothing. Then the crashed became too frequent and the CD started openig up automatically. i reinstalled windows. same errors. used SFC, but nothing. Then the system after crashing, it gave me a warning, INVALID command interpreter. I restarted and it booted fine. I reinstalled again and reformatted. But again, same problem. I removed RAM and reinserted. NO change. I checked RAM with NU 2000 and RamExam by qualitas. I checked my HDD with scandisk and NDD with NU 2000. No errors absolutely. Even did a complete surface scan. Nothing. Still continues. Checked for a virus, using NAV 2000 virus defs dated 17/03/2000. Nothing. I tried everything I knew. But nothing again. My system doesn't show any errors anywhere, in device manager, troubleshooters etc, or with Norton Diags. I solved many problems in various mesage boards, but I find mine the toughest. The BIOS shows no problems. The motherboard has an Evaluation ROM as it says. Does that make any difference? It says not for sale. The MB is a month old. VIA apollo board. THe HDD and RAM are 1 month old. No errors whatsoever with any utility. But the system crashes are very frequent. Please help.
