The problem is as follows: I just got my dad's computer and have (had) a bunch of MBs, AM2 processor standing out.
His AGP slot had some problems and the computer refused to start with a video card other than the on-board card.
1 week before:
- MB1 - processor 1 - power 2 => perfectly working
- MB2 - processor 3 - power 3 => perfectly working
- MB3 - processor 3 - power 2/3 => perfectly working
Replaced his MB with a mb of mine (MB1), but left his power supply (which to be honest, apart from the 24-pin connector had another one with 4 pins connected to his MB) and tried it.... The results are as follows.
MB 1:
- processor 1 - power 1 => smells burnt and make annoying sound (possibly mb voltage regulators)
- processor 2 - power 1 => same
- processor 2 - power 2 => same
Replaced MB1 with another MB of mine.
MB 2:
- processor 2 - power 3 => smells burnt and runs for a couple of seconds
- processor 3 - power 3 => smells burnt
- processor 2 - power 2 => same
- processor 4 - power 2 => smells burnt instantly
And finally changed everything except the power 2 (which was perfectly ok 1 week before)
MB 3:
- processor 4 - power 2 => smells burnt
Is it possible that power 1 burnt MB 1 which in turn burnt processor 2 and power 2 which in turn burnt MB 2 and 4 and processor 4?
I know it sounds crazy, but is it possible to get them burnt in chain???
I'm very curious what I got wrong, because I now have 4 MB, 4 CPU, and 2 PSU apparently broken, and I don't want to burn the last ones.
Are you sure that the surface you are using isn't conductive? You can test power supplies without having to have a motherboard attached, google for more info (it usually involves attaching a hard drive for some baseline load and bridging two pins on the ATX plug). – Ruairi Fullam – 2011-07-06T14:27:14.607
I'm testing on the carpet – Andrei Zisu – 2011-07-06T14:31:34.490
Carpet = static electricity = fried components. I would at this point put everything down and solicit the services of a professional. – LawrenceC – 2011-07-06T15:37:50.130
It's hairless carpet... It can't generate any... – Andrei Zisu – 2011-07-06T17:14:36.113
Does your mainboard has some configuration jumpers for cpu bus ratio and stuff like that? – Sean87 – 2011-07-31T17:45:25.557
