Question about Computers & Internet
2 Dead popped capasitors on main board: C124 and C126 470uF 16v Replacement did not fix. PSU making a hissing noise near the transformer when plugged in. No power what so ever. Once turned on a white screen. (usually blue for no signal / idle) Noticed badly darkened part on soldering side of the PSU. Item verification number Q601 item barcode: D F / R W. No idea what part to look for.

SOURCE: psu shut down
99% TIME IT IS A FAULTY FAN GOING OUT.
REPLACING THE FAN INSIDE THE POWER SUPPLY WILL RESOLVE THE PROBLEM.
P/S ARE CHEAP, JUST BUY A NEW ONE OOR REPLACE WITH ONE YOU HAVE ON HAND

SOURCE: No picture on N3250W viewsonic
I just had a viewsonic supply all apart with a blown capacitor, I believe c36. q7 a surface mount npn transistor on the solder side of board was shorted. Replaced cap and transistor, set works fine. Also, check all your electrolytics on this board as they sometimes swell and go bad.

SOURCE: PC will not power up
Check that the ram memory hasn't come unseated from the mobo. If you are using an above board video card also check that it is properly seated as well.
The clicking noise from the PSU is kinda perplexing though...
