Update: installed vista 64, no LAN cable hooked up. Let sit for 20 mins, locked up. I had to literally disconnect everything inside to get it to bootup, but still locking up.
I dont quite understand how unplugging things, and then re plugging them in, gets this machine to bootup?
whats causing these lockups?
I think it's safe to say that something at the hardware level is broken. As you said, the fact that a different PSU changed the behaviour, at least temporarily, is very telling. The fact that it (sometimes?) won't even show video during the POST cannot be caused by software.
As a suggestion, don't attempt to boot to Windows at all, but instead stay in the BIOS configuration menu for extended periods of time. Use that as a gauge of whether any changes you make have improved matters.
While the machine keeps on freezing in the BIOS menu, it's absolutely borked at a hardware level.
Seems the common denominator is all testing so far as been the memory modules?
It seems to be if I leave the computer and it hibernates when I turn back on they keyboard is dead so is mouse so is all output even video and sound even resetting has not brought it wound this time.
