I was recently donated about 50 p3 800mhz and 800x2mhz p3 servers.. woot

just got another windfall.

a donation of about 40 p4 servers..

i knew ahead of time that at least half would be iffy, as they were pulled from production for some reason or another (could have just been a failed hdd).. the company was pulling old servers if they had ANY issue and moving the customers to new servers. over time they accumlated a bunch of stuff and elected just to donate them..

So I'm the tech going through the donation.

I already have about 15 P4 2.2Ghz-3.0Ghz motherboard/cpu/ps combos that boot up just fine to a point they complain about not having a boot disk. I haven't stress tested them yet (or ram mem test), but I'm trying to seperate the "probably goods" from teh faulty servers.

I have a pile of about 12 machines (same p4 array) that will power on, even start to post BIOS, then shut off... they spin up for a few seconds, and go down.. i have to reset the power supply, disconnect the cable, and wait like 10 seconds to get them to poer back on.. just hitting the power button after they go down doesnt spin them back up...

I'm wondering what the problem is.. I'm thinking it is either bad power supplies, bad cpu's, or maybe even just a bad connection between the cpu and the heatsink (maybe need to redo the thermal paste)... I'm going to go through all the PS's tonight with a tester

Any ideas?

Like you said, probably the psu/connections have gone bad. Could just try swapping the PSU in 1 system and see if that fixes the issue. Best to use a multi-meter in this situation I suppose.

ahhh. good point, i guess even if a PS tester shows the PS is good, it doesn't speak for all the individual connectors, which could be a problem.
