Okay, so here's the problem when i start up my computer it switches ON for like 7-15 than it switches OFF by itself than it switches ON by itself than switches OFF by itself.... This cycle will keep going on unless i switch OFF the PSU....
So when send it to the shop they said it was my motherboard and that the problem was due to my SOUTHBRIDGE on my motherboard so what i did was change my whole motherboard and the same problem happened again. It is definitely not my power button or my PSU i diagnosed those parts already and i m pretty sure it isn't due to my RAM so that only leaves my processor.

So my Question is "Could my processor cause the problem of my PC switching ON then OFF by itself if not... what else could cause this kinda problems"?

Yes, the CPU can easily cause these problems. You should definitely replace the PSU (antec, XFX, Corsair, Seaosnic) as it could likely be the cause of the CPU failing. The only real way to test this is to put it in another computer.

The RAM could also be at fault. I would test that first.

You should give more detailed information about your system, motherboard,cpu, psu...
Anyway i had a similar problem 3 weeks ago. My motherboard didnt support my cpu out of the box but needed a bios update first. Maybe that's your problem. If not, the power supply is the next thing i would check out.

I m using I3 540 LGA1156 socket, Gigabyte H55M-USB3, 4 GB RAM, (i dont know exactly what you want to know about my PSU but i will just put the name and the full specs
output capacity: 550 watts (peak) 500 watts (continuous).
Input voltage: AC 100-240V (Auto range).
Input Current: 6A at 115Vac / 3A at 230 Vac
Input Frequency Rang: 47 - 63 Hz
Hold up time: >17 ms
(on the front description that say PLUS 80)
but the thing is all the specs i'm using is compatible because i have used it together before... accept i had to like change my PSU but otherwise everything is the same and working

That PSu is complete junk. VERY low quality and likely only makes about 400w max.

It is not officially 80+ certified. It is from a low quality OEM. It only makes 17a on each 12v Rail. I have a 450w PSU which makes 36a on the 12v Rail. this may be 550w but you couldn't even run a low end GPU on it without running into all kinds of problems. Put simply, it is not a good PSu in any way.

ok...?
but you're not answering my main question you're simply criticizing my PSU's cheap build. let me tell you this if i had money i would gladly spend a few grand on my system but guess what??? I Dont have a few grand i dont even have a few hundred bucks, i m broke and in debts so i went with the most reasonable option i had at that time,,, so i don't need someone who thinks he has the most awesome system i m just trying to get my system working and get the most of it. can you please consider how other people feels if you suddenly just degrade their things... i found your previous comment awfully crude and down right demoralizing and in no way did it answer my question

The PSu could be the issue here. The PSu is the most important part of a PC and the last place to try to save money. My system is by no means at all the most awesome system, nor do I act like it is. I am just giving you the facts as to why your PSu may be the cause of the problem.

Poor quality PSUs can cause MANY issues, this being one of them. They have very un-regulated voltage fluctuations which can damage components. This would be the reason your CPU is fried, if that turns out to be the issue.

how recetly have you taken apart anything or changed components.

one thing to try is to disconnect ALL the fans, HDDs, DVD, drives and try to boot. Also, try one one stock of RAM in each slot one at a time.
One thing to try
Also, do you have a GPU?

i have tried several different PSU (one of them being cooler master but i cant remember the detail of that PSU) but the same problem persisted and i only use a single 4GB ram stick and i have dissconnected my dvd drive but the same thing is still happpening
i have tested everything in the book
so the only thing left is my processor so my question is "can my processor cause such problems"?
