I've put together an X2 AMD PC with following components:

Optical Drive: COMBO LG|GCC-4522BK 52X32X16X
CPU: CPU AMD|A64 X2 3800+ AM2 2x512K
RAM: MEM 512Mx2|CORSAIR TWIN2X1024A-6400
CPU THERMPASTE: ARCTIC SILVER5
Video: VGA BIOSTAR 7600GS 512M V7602GS51
PSU: PSU THERMALTAKE | W0070 430W
HD: 250G|WD 7K 16M SATA2 WD2500KS
PCI Net Card: WRLSS-G PCI ADAPTER|LINKSYS WMP54G
CASE: THERMALTAKE|VA8000BWS
MOBO: GIGABYTE GA-M55SLI-S4 NF4 SLI AM2

Followed the manuals as much as a male possibly can. Two connectors (HD LED and something else in that mobo region) were not connected right polarity-wise, which I fixed and reconnected.

Turn on the PSU (has switch in the back) - nothing. Press the ON switch on PC - nothing. Noticed a hardly noticeable "click" inside PSU and also hardly noticeable current disruption in overhead lamp when switched PSU on. There was nothing at all - no fans running, no LEDs turning on, no beeps - total cadaver of a PC. NO smell of burning or smoking, either.

Took out the PSU, connected to power, tried turning it on by itself - still nothing. So, at this point I thought - it's PSU. Went out and bought a 600W this time. Connected it to the PC - same case scenario.

Now the PC is in the local "dude-shop", where they will run diagnostics on it.

QUESTION: What could be wrong based on this information? Spent over $1K on the parts for this thing, it's anything but generic!

STEPS TAKEN ALREADY: *Reset the PSU by pressing power button in with it unplugged for 10 seconds - did not work**Disconnected the Reset wire from mobo - nope*

Much obliged in advance.

I would started at being sure the connectors were seated,then connected only the MOBO to PSU to see if board lit up. Board may have been bad to start, it happens.. I know it happened to me right out the box.

By far the most common problem that I have with new installs is seating the connections. It never seems to fail, no matter how much care that I use, but one of the connections always seems to be the problem!

Past that, it could be any of a number of things. It could be a bad mobo, video card, NIC card, processor, PSU, etc (stuff happens! :thumbsup:

OK - found out what the problem was. Apparently, the front panel audio connector was shorting out the board. Uplugged - everything works without it, and the computer is as good as... well, it is new. Anyway, hope this helps.

Thanks for cutting out the bad link there "Trial".

I was just about to do so as you did it.
The only easy day was yesterday.
