Intermittant failures reported, now what?

[DarthLoki182]

I have run PC doctor  multiple times on a computer I am working on, about half the time, PC doctor passes it, the other time, it fails. 

Screen, when it fails is garbled.

Which PC-Doctor product are you using?
What environment are you testing in (DOS, PE, Windows)
Which test(s) are you running that are displaying the intermittent failures?

I am booting from the 7.3 flash drive.  Test 5 Motherboard/video test failed.  Unfortunately the display was too garbled to read.

It passed the short test both times.  Upon reboot, everything appears fine, there is no garbled screen any longer (it was even garbled on the welcome screen). 

I have rebooted six times, no problem evident.  (tested in DOS, because I could not get into windows)  I will be trying the windows environment next.

The garbled text could be a result of loss of video memory, which would also result in a failure.  The failure can be intermittent if the video memory block with the issue is not hit every time during testing.

Thank you, that turned out to be the problem
