Anybody run a Maximum System Load test?

[Thinker]

Hi,

I have run the Maximum System Load test on PC Doctor 2.0 (DOS) on my "new" Certified Used T23, but the computer hangs. It won't even respond to Ctrl-Alt-Delete, so I need to push the power button to have it shut down. This is the 5 minute version of the test.

Also, I have noticed that the fan doesn't kick up on startup (as the previous T23 that I had did). I thought that the BIOS starts the fan for a second or so as a test on startup, and mine doesn't do that. Is it possible that the Maximum Load test is failing because the CPU is overheating? Anything I should be concerned about? I wish there were a way to test that everything is OK. Incidentally, the Windows version of PC doctor included with the T23 doesn't report any errors. However, I can't find a Maximum Load Test there, and I can't find a fan test either.

I would appreciate any suggestions.
