Compuer won't turn on

PizzaD · 09-07-2011, 07:35 PM

Ok, i was using my computer to type a Microsoft Word Document and my computer randomly turned off without warning. I opened up the computer and found that the little green light on my motherboard was lit. so i waited a few minutes and tried to power up again. when i pressed the power button the fans would start but only for a few seconds before shutting off.

I keep trying and i only get the same result

CPU: AMD Phenom ii X4 925 @ 2.8 ghz
RAM: 8 gb ddr3
OS: Windows 7 Home Premium 64-bit
GPU: AMD Radeon HD 6870
PSU: Corsair 550W

It could be that your computer is overheating. Have you tried to turn it on since you posted this?

PizzaD · 09-07-2011, 08:35 PM

I have. everything inside the machine is cooled down and the problem persists. i aslo checked that my connections from the psu are tight. also i removed the graphics card and put it back in just in case. i also used a CO2 duster to remove any dust from the machine.

Check if any of the mobo's capacitors are bloated or leaking.

What do you mean by bloating or leaking? can you describe it?

habibjp · 09-07-2011, 10:34 PM

If they are leaking, yellowy stuff will have oozed out, and will be visible around them. If they are bloated, the top/bottom of them will have become rounded (as opposed to flat).

i looked and i found no evidence of the capasitors failing/bulging/leaking.
i went to corsairs website and they told me to do the paperclip test and i did it and the only thing that happened was that the psu fan started up but after a second or half a second it stopped. like when it was hooked up

ok, i discovered the problem and the PSU is dead. i am calling Corsair tommorow for an RMA.

Good to hear the problem is solved.

What is the paperclip test btw?

using a paperclip to short the contacts for the power switch, to rule out problems with the power switch.
you can also use a screwdriver.
do it wrong, you short out the board (i've done that once, and sent it in for warranty

)
