computer reboots - unexpectedly & inconsistently
have done:
- ram test 10 passes (6 hours...): no faults
- hard drive test: passed
- stress test: 27 minutes - didn't fail

was doing a defrag - rebooted & wouldn't acknowledge the hdd

any thought of what to check next
realized haven't scanned for malware - will do that now

any other thought?
Thank you

Will it boot into safe mode / safe mode / networking without rebooting? Go into the BIOS, does it recognise the hdd?? If it doesn't try replacing the cable to the hdd. If that doesn't work its probably dead

Looks like TFSysMon belongs to threatfire. Uninstall it. The other 2 may belong to Stopzilla. Uninstall it. Run tddskiller on it (http://support.kaspersky.com/faq/?qid=208283363). And do a full scan with something like malwarebytes

Couldn't find either threatfire or Stopzilla to uninstall it.
Ran tddskiller on it: clean
Full scan with malwarebytes: Clean

Those entries that you posted may still be in services then. Or in device manager, Go to device manager / select view / show hidden devices. What version of windows is it? If it's XP, click on non plug and play devices, I think it is, find those names then delete them. Then reboot.

Or if ccleaner is installed, see if any of those names appear in startup. If they do, highlight them then delete the entries

If it is XP, the entries may have an X or ! beside them. Dbl click on them. It should show the names of the drivers you posted

I wanted to report back & close this thread.
I found the culprit was a faulty sata cable
when I replaced it no more problems
many thanks to everyone who helped
