Hi, my computer has been working fine for over a year now, I built it in September 2012.
But just this morning it randomly cut off. I tried turning it back on and now it turns on for a few seconds (lights on the front, lights come on with the dvd drive as well, fans spin including on the PSU) and after a few seconds it just turns off. A few seconds after it turns off it turns back on again, does the same exact thing over and over. I'm sick to my stomach now because of these problems. Any ideas on what to do? Thanks :)

For the most relevant answers, please specify your parts. Include the brand and model, not just wattage, of your PSU.
Possibilities that come to mind include a dead CMOS battery, or something has crawled into your case and died, shorting something. It is probably not the PSU, since it turns back on by itself; a PSU suffering effects of aging will typically just shut off. Also, make sure the power switch has not developed a short.

Thanks for you response.

I have a Corsair Tx650 bronze edition.

That makes me feel a little better knowing it's not the PSU. How can I test other parts? My room does get dusty but I clean it out every other week and it's usually dust free, nothing would ever be able to crawl inside and die in it though haha.
My GPU has been working perfectly, low temperatures and all. Is it possible maybe a virus or some other sort of software problem could be effecting my hard drive?

How can I tell if the power switch has devloped a short? It works fine when I press it to turn it on every time, no delay or anything.

This will involve using System Recovery. There are instructions on that site to tell you how to use System Recovery.

Thank you for your response as well, it makes me feel quite a bit better knowing random people on the internet are so kind. This sounds like exactly my problem. I just cant see it being hardware failure. I installed windows 7 on my computer using a flash drive though. Am I out of luck? Is there a way I can wipe the hard drive without the use of another computer? I have another computer in my house but it's pretty old and still running windows XP.

My gut is telling me its the hard drive or software related though. Any further suggestions from here?
Again, thank you so much.,
