Strange system instability

About a week ago something really off happened while gaming. Mouse, keyboard, headsets everything stopped working and appearently shut down. My screen froze and never responded and i was forced to force reboot just to experience somethign even worse. I could hear then fans working, i saw the fans from my CPU and my GPU along with the light and the fan of my PSU working but nothing happened no beeps, no boot, nothing.

Today i tried to turn my pc on after a couple of days of not touching it and somehow it worked just fine but when i turned it off and tried to turn it on again same thing happened.

Im not sure what could cause this but it is just odd. i feel like it might be the PSU, just a hunch but i ahve no experience to trust on it.

By the way, sometimes when i turn it on, everything turns on for a couple of seconds then shuts down and once again goes on and boots in just fine.

MY PSU is a Super Flower 700W sf-700k14a
Gpu XFX HD Radeon 6870
CPU intel Pentium Dual core 3.0GHZ
MOBO G41M-VGS3 R2.0/G41M-VS3 R2.0
 
Solution
As I said earlier the main suspect is PSU, other than that the MB or GPU could be faulty. Try to borrow components from someone to test.

When booting no beep means the MB is dead.

Now im not so sure about what is causing it. I tried using another PSU, a generic one which came along with the original pc. It had a 400W capacity but it is suppsoed to be enough to run the system without my GPU. I removed the GPU and tried but yet same thing happened.
 


So that leaves you with the motherboard, CPU, memory and hard disk drive(s) to test.

From the start that's what i thought as well. But like i said i was able to turn it on just fine, beeped and booted perfectly. Maybe its not entirely dead (But obviously its just screwed).

I will have to assume that it is the MOBO and perhaps there might be some issues with the PSU as well.

Anyway thanks for your help.
 
You are welcome. Try to test those components before buying new ones. A local tech will help you to troubleshoot the exact faulty item if you have no spare components on your hand. Good luck. And I would suggest you to buy a good/rated PSU. Like XFX, Corsair etc.
