Just something to put in your "bag 'o tricks"...
ALWAYS check that little slide switch on your power supply !!!
(unless you have one of those "universal voltage" units)
I should have spotted it right away; but I was complacent and frustrated at the
same time. I'd been snagging and scrounging new and used parts for about six
months to build a machine. One of the bits was a decent case/power supply was
on clearance; it was the display unit .
I put in an almost new K7N2 mobo (MSI)that I pulled from an upgrade (owner
wanted the SATA and Dolby output of the G model for sound editing) ; an XP1900
tbred that was "probably good" (came out of a machine that fell off a shelf
while unpowered that had severe cracks in the mobo) ; known good ATI 9700Pro;
known good memory and the usual stuff..
CPU fan ran; no post !
Took it "down to basics"; mobo on a wood board with only CPU; memory and an old
PCI vidcard that I trust....STILL no post!
Thinking that the 1900 CPU didn't survive the fall; I went out and bought a 2500
Barton (which I probably would have done eventually ;} ). Still -- no post!!
Dug out my homebrew AT/ATX power suppy tester and voltmeter; everything seemed
OK on the rails; 5v and 12volts within spec. My loads are pretty small -- maybe
a half-amp per rail .
I walked away from it ; went on vacation for a week ; came back to it.
Damned if the white-on-black *220V* wasn't screaming at me !!.......
The BEEP was like a miracle... seeing the BIOS screen was akin to a religious
experience!!
It's a good thing my 'mains' is Yank 120v; no damage. If I was somewhere else
and it was 240 mains and the switch was in 110 ....... smoking hulk !!
Still working out some small things but it's great--
