Computer keeps sort of turning itself off

[LapX]

Hey guys, I got an issue with my second computer that my mother is using.

 

When idling, the computer keeps sort of turning itself off, what I mean by that is that everything seems to keep running, but the screen is black and I have to cut the power via the PSU to turn it off, then back on because the reset and power buttons doesn't work while it's in that state.

 

The issue is not heat related, neither caused by bad components, I've been running the everything except the GPU and PSU in my primary computer for 3 years without and issue. I built this one with the parts I didn't need anymore.

 

Specs :

 

CPU : Intel core i7 930 @2.80GHz with stock cooler (I once had it running @4.0GHz with an H100i)

Mobo : Asus P6X58D-E (LGA 1366)

RAM : 3x2GB Kingston value RAM

GPU : Asus radeon 7790 DirectCUII

PSU : Corsair CX500 80+ Bronze

HDD : WD Green drive 2TB (I took it from an external hard drive)

OS : Windows 7 Family premium (or w/e it's called, I got it in french)

 

I got a couple ideas for that behavior, but before I start testing I'd like to know what I should do first/is more likely to cause the problem or maybe you have a solution I didn't even think about. I'm writing them in order from more likely to less likely.

 

1. HDD is an environement friendly drive so it turns itself off when idling and can't turn itself back on.

2. HDD is too slow.

3. RAM is broken/corrupted.

4. PSU has too low wattage for the components it's powering.

5. Some weird standby os settings.

 

I appreciate any help, thanks for taking the time.

I'm sure this probably isn't the issue, but what are your power settings for sleep/hibernating/turning off the displays?

I turned every sleep option off (that I know of) as I always close everything I need when I'm not using a computer.

do a test with another GPU if you have one lying around and see if the black screens appears again

 

if you suspect RAM trouble

 

do a MemTest

 

use HDD Crystal Benchmark software to check HDD health status

Try using Spare working RAM if you have one laying around or borrow from friends / family.

Sometimes in rare cases MemTest can't detect any problem yet the RAM is actually broken.

I already ran memtest86 with the 3 sticks in, it had no error, you guys really think it's the ram ?

well we can't tell either but it worth to give it a shot

 

test your PC with borrowed RAM and GPU

Well you got nothing to lose. If borrowed ram or GPU doesn't fix it. then you know that your RAM and GPU are not the problem.
