Hi,
I hope that someone out there can help...
I'm working on a friend?s computer that seems to have blown. Everything was dead. Checked power supply and the fuse was blown, replaced and still nothing, just re-blew the fuse. Everything, all fans, components, heatsinks were all buried in dirt and lint. Cleaned everything out, replaced power supply from the 400w to a new 450w. Still nothing, bridged psu and fans kicked in. I suspected the motherboard. Replaced the gigabyte mobo with an Asrock 775i65G Motherboard, put new in heatsink and fan with application of new thermal paste and still nothing. Tested psu and all ok. When everything connected, turned on and nothing, however, when turning off from the switch at the back a slight backward sounding chirp type noise, comes from the psu. The question is, where to next?
Any and all help would be extremely appreciated, at my end of my tether!!
Computer is a P4 3ghz, 775 with DDR 400 (1gb) 160gig HDD.
Cheers and all the best.
Rob

Unplug all cards and drives to see if that lets the P/s start. Then start adding items one by one to see what faults the P/S.

Hi mjd420nova,

Thanks for the prompt reply it is extremely appreciated. Did as you suggested, removed all connections to the drives and pci card. Tried to fire it up and... nothing. Although the psu did make a slightly different noise, tho very faint. Had a look around and the only other thing left on the board, besides the cpu, heatsink+fan and ram was the USB 2.0 header, disconnected that and hey presto, away she went. So then I reconnected everything back up, including the pci modem and then... nothing. Removed the pci modem and away she went. GREAT NEWS! Thanks guys, very much appreciated. I think that this makes the two front panel usb ports dead, but hey, the board has 6 usb ports on the back anyway... and besides how many usb ports does a fellow need anyway? So it looks as tho whatever it was, spiked the motherboard, psu, usb 2.0 header and the pci modem, not a bad effort hey!

So thanks again and all the very best.
