Hello everyone. I hope this is the correct place to post this.

My PC has been dead for almost two weeks already but was too busy at work to get back at it.

First and foremost, here are my PC specs are as follow:

Intel Core i7-3820 3.60GHz
NVIDIA GeForce GTX680 2GB
750W Delta Electronics PSU
16GB DDR3 SDRAM(PC3-12800/4GBx4/4channel)


Got 2 HDDs

SATA3 2TB HDD
Samsung 120GB SSD (840series SATA6Gb/s) (Windows is installed here)

If you need more specific info, let me know.

Now, regarding the actual issue... it all started about 2 months ago, when my PC suddenly decided to shut down. I tried to turn it on and it would go into an endless loop without even reaching the BIOS screen. Sometimes I could even hear some sort of scratchy sound.

After a few tries it came back to life but it happened again a month ago. Again, it came back to life. Last week it happened again and I tried booting it without any USB nor anything connected, and no luck. It came back one but turned itself off after a couple hours and now it's been dead for a week.

When I turn it on the fans start, the motherboard lights go on (the little + and - buttons and something else), but the keyboard doesn't even turn on and after some 20 seconds or so it just dies and restarts again.

Having done some research it seems like the HDD or the PSU could be faulty, but then again it might be a completely different issue..



Anyway, if you guys can help me out here, I'd appreciate it. I'll be paying attention to this thread to give as much info as possible. Thank you!

Adding some extra info:

I checked this thread http://www.tomshardware.com/forum/275856-30-gigabyte-guide
And went through the LOOP parts and the "'Power related' boot loops" seems to be the closest to the symptoms on my PC. I went to the Power Supply - Basics and read what they said but I don't have that meter, and the other system with the paper clips seemed to be quite... complex.

What would be a good way to test if the issue is with the PSU?

Still searching but can't find anything. I guess my description of the issue wasn't good enough so it's hard to help?
If there's any extra info I can share, let me know.
