computer just shut off and won't turn back on

sethovahea · 09-29-2009, 10:53 PM

Ive had my newly built system up and running for about a week. All of a sudden while using it, it just turned off and wont go back on. There is a red light on in the front but I get dead silence when I try to turn it on. Could be my power supply went bad already? The case/power supply combo cost $35. I think its a 400 watt supply. I got it from geeks.com.

A power supply that cost $35 by itself should be highly suspect. One that costs $35 WITH a case is guaranteed to be the trashiest trash around.

What are you running?
Motherboard
CPU
RAM
Graphics card

System Specs?
Brand & Moel of Mobo-CPU-RAM-Graphics-PSU.
Totally agree with Phædrus2401 about the PSU. A $35 case/PSU combo has to include a junk PSU.

intel915 motherboard/3.0 cpu. 1gb ram, windows 7. The green light on the motherboard comes on but the comp wont turn on. Im going to use a friends power supply and see what happens. Im at work so I cant remember too many system details. dvga(or something like that) 9400gt. Im at work so I can't remember too many details but those are the basics.

just because the green light comes on doesn't mean the power supply is ok, it only means that your motherboard is getting power.

So I guess my psu to a crap that could choke a donkey? Could it be anything else?

it could be a combination of things but unlikely start with the power supply,550 is low by todays standards so you may be able to borrow one to test with but it needs to be a quality 80+ with a min 550w

update: It was the power supply!!! Now I need to find me a nice quiet one, along with a 120mm quiet fan. IF you guys recommend any that would rule. I'm new on this site so I don't know if I'm posting in the right forum.

corsair and seasonic are the best power supplies along with pc cooling ones.

Like the one Dai mentioned above with a link
