T2x problem reloaded

[synchromesh]

Ok, here is another problem I have with a different T22 I have.

Basically it all started when I removed the original 900MHz processor. I haven't tested it extensively before that but it seemed to work ok. After I removed it and upgraded to 1GHz strange stuff has been happening.

It boots up just fine, detects all of the attached hardware fine (CDROM, hdd, etc) and then when I start installing Windows or try to boot from Linux live CD at some point the screen goes blank. The CDROM drive LED lights up once in a while but with same intervals and in same pattern. I can hear the hdd being accessed, also in a particular pattern. And that's it. It doesn't respond to anything, sometimes not even the power button to turn it off.

It feels almost like a thermal problem. I tried various CPUs (couple of 700s, couple of 1GHz, and the original 900MHz). Same difference. Tried 2 different heatsinks, the original T22 and one from T21. Same thing. Of course I applied gobs of AC5 on all processors and made sure the ZIF screw is in proper position, so that's not it. Tried all of the connections, etc.

Any other suggestions?
