Screen goes black randomly

[Abd Allah]

Hello Everyone,
I have a problem with my PC
- CPU: AMD FX-8350
- Motherboard: Gigabyte GA-990FXA-UD3 (rev. 4.0)
- Graphics Card: Gigabyte AMD Radeon R7 260X (2GB DDR5)
- RAM: Kingston HyperX Blu 4Gb 1600 CL9
- Hard disk: Western Digital 1TB Blue
- Power supply: Zalman ZM600-GV (600W Bronze)
- Case: Corsair 200R

All new components except the screen 'ViewSonic E70-3'

and the problem is
1- Screen goes Black 'RANDOMLY' (keyboard is okay for a couple of seconds - Numlock is working)
2- keyboard and mouse after that is not working (lights are on but there is no response)
3- Cooling fans and lights of the case are okay, also CPU fan is okay
4- I have to restart the PC from the case power button
5- and everything is okay after the restart

Notes:
--> Videos from youtube is running and I hear the sound
--> There is a DVI-VGA converter

Thanks

You say it goes black "randomly". How long does it usually take? Two minutes? Five hours?

The problem is not with the monitor; it is the computer. Also, it could be the cable, but I think that is unlikely.

PC may run for a couple of days without a problem and may run for a couple of hours and then the screen goes black

Does this happen while you are doing anything specific? Like gaming, or doing something else that heavily uses the CPU?

i am sure its either the board or the psu or both.... i had exactly the same problem like yours and after couple of months my board totally died along with my psu....so check your pc with a different psu and if the problem persist then change the board or if you have the warranty use it ....

No, at all
Sometimes with only a casual browsing or running nothing but speedfan program

Once it happened while the CPU usage was about 10% or less

Then I agree with prit87. I would change the PSU, and see if that fixes it. If not, change the motherboard.

If you have another PSU lying around or in another computer that is powerful enough, you can try using that.

Here's a good PSU if you buy a new one (it's a good price in the US, at least):
XFX P1-650S-NLB9

Congratulations on your first thread, by the way!

I remembered something related to the motherboard

The North Bridge temp. is always higher than CPU temp., Is that normal?!!

Sometimes with a 20° C difference

 

[wolverine96]

What do Temp1, Temp2, and Temp3 stand for in the image? Which one is CPU, and which one is motherboard?

Temp1 is the motherboard's temp., Temp2 is the north bridge's and Temp3 is the CPU's

Okay. Those temperatures look normal to me for 100% load.
