I have a client that has an older PC with a IDE hard drive in it. Wehn powering up the system she got the above error. So I took into the shop anticipating a bad drive. Not the case. I cloned it to another drive with no errors reported during the clone. Installed the clone drive and the system booted and ran just fine. OK so it looks like it is solved. 4 days later she turns on the computer and the same error happens. Once again in the interest of getting my client running I just cloned the drive and put he clone in.
Now I replaced the IDE cable reseated the power connector etc. Reseated the memory modules and all adapter cards.
BTW I ran a virus scan adware scan etc and verified a clean system.
Thinking there may be a problem with the power supply I ran a test on it and found high and low voltages so I installed a new power supply. The system ran fine for a week, with her turning the computer off at night and on in the morning. Bam Friday morning the same error. Once again a clone and back up and running.
Any ideas as to what is causing this?
