Hey guys,

A little backstory with this pc. I built it 2 years ago and have had never ending problems of bsod, corrupted files, hard drives disappearing randomly, extremely poor fps drops during gaming etc. I have had to have warranty done on the gpu and motherboard and the ram has also failed and needed to be replaced most recently.

Now to my new problem, my pc was randomly shutting itself off. Not often, not underload of gaming or anything just at complete random times. Sometimes id have to wait 5 minutes before i could turn it back on. Last night however it turned itself off and is not turning back on. However when plugged in mobo lights are on and lights on the gpu are on but when i hit the on or reset button nothing happens and the fans dont spin up.

I have also replaced the psu with a brand new one and tried multiple power cables but nothing works.

This pc has literally given me nothing but trouble since i built it and i honestly have no idea how or why. Any ideas would be much appreciated.

Thank you.

Edit***
Forgot to mention if i boot without the button using a screw driver it will light up and fans spin for about 1 second then immediately shut off.

No post, no fans on gpu spinning or case fans. The lights are on the gpu just show that it is correctly plugged in and receiving power thats why i mentioned it but no fans spin up or anything like that.

Update*
Ive gotten it to turn on, fans spin up but no post and then the system restarts itself and repeats. This happened a month ago and i had it repaired. They said they had to replace the ram. Surely the the ram couldnt fail again this soon something has to be causing it?

On a PC that works download Memtest86+ and burn it onto a blank CD and then test the system RAM in the computer you are having problems with.

The first 3 diagnostics (antivirus, memory, hard drive) are bootable (as softwaremaniac stated).

I actually have a separate page with just them:  http://www.carrona.org/initdiag.html

You can also use this page to help rule out other hardware bits and pieces:  http://www.carrona.org/strpdown.html

 

Good luck!
