Yes it sounds like the power supply is shot, you can get a replacement at any computer shop for around $40. i would put in a 400w or 450w that way if you add another hard drive or opitcal drive it wont be a strain on the new power supply

Computer will not turn on. green light blinking


Try replacing the power supply, a blinking green light usually means the power supply is missing an output voltage. If you do that and you still get a blinking green light then the motherboard will need to be replaced.

Profile 3 won't power up, green light on power brick blinks when connected, green light steady when disconnect from computer. Is the problem in the power brick or the computer itself? Thank you.


You can daignose if the problem is with power brick or computer itself, by connecting any other electorinc device from power brick. See if the green light continue to blink. Further there is a chart given on the power brick, which indicates which lights should be ON for normal state. You can also try replacing the phuse on power brick, if faulty.

Hp desktop wont start


I think you have more than one problem there. Take it to a local PC repair shop and have them check it out. Five years is a good age for a computer though so you may want to think about buying a new one. Best of the Irish Luck to yer.

Hp pc m7640n won't turn on and power supply light is out


OK, this can be a hard thing to fix. Most of the time, the power supply is the first thing to go on a PC. However, when you stated that the motherboards LED came on after you unpluged the PS from the motherboard, it leads me to believe that the motherboard is the issue but the power supply might be outputting higher voltages and the motherboard might be shutting down. Since the power supply is cheaper then most motherboards, I would recommend getting a new one. Check ebay for a new power supply. It should be about $20 with shipping. If the same thing happens, then you need a new motherboard...

Computer will not boot up after i disconnect power


If the component with the blinking green light is on your network card, it has nothing to do with your problem, but does demonstrate that *********** board is NOT fried or there would be no voltage available to make the light blink.

Something on your board may be fried, but not the entire board.

Unit needs board level service, so obtain an RMA, if available and submit the unit for bench testing and service.

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...
