Looks like i wont get to test out the PSU theory hondaguy, my 79-t is acting up, im not sure whats going on with it. Was taking my wb off and a bit of glycol slipped past the oring onto the board, not much, and it was an easy cleanup. But some of it got underneath the heatpipe assembly that covers the nb/sb/fets, removed that, cleaned up the board, let it air out a bit. When i went to put the heatpipe assembly back on, i couldnt reuse the thermal gunk that was on it, put some as5 on instead, now im having problems booting. It will boot into windows for about 10 minutes, then it just turns off, turn it back on, and it'll load windows for a couple of minutes, then shuts off. Every restart shuts down sooner and sooner, until it wont post. If i leave it for a couple of hours, it will boot windows again for about 10 minutes and the cycle repeats. Im thinking its not anything to do with the glycol spill, as it wouldnt work period if it had shorted out and fried something. Im thinking maybe its not remounting properly on the other chips. I've mangled up the heatpipe a bit so that i could put a small ramsink on the sb to see if that mount was bad, but the sink doesnt even get warm, and i get the same shutdowns. My mb temps read from bios and windows are all under 30c, which im thinking is the nb temp, so thats not hot. maybe its the pwms? all seems kind of wierd, especially since i've seen pwms run naked before so they shouldnt go thermal with stock clocks and volts, but nothing i seem to do helps...
