Desktop randomly shut off

  1. Hello again everyone!

    I wish I could return upon a more happy note, but in the middle of my Dragon Age: Origins gaming, my computer had just randomly shut off. No shutting down message, it was as if I had just flipped the switch on the PSU. Now, whenever I go to turn on my system, it will give a couple of LED lights (I have Led lit fans and a led lit graphics card) for about 1 sec, and then go back to its stubborn, self induced coma. I don't know why it had a computer heart attack, but it did.

    I think that it may have something to do with a power surge back a couple months ago while I was out of town (my father informed me of this). Had an other PSU (600 Watt) that gave my video card a d1601 overheating error, which was pure blasphemy. I hadn't even turned it on that day. Sooooo, I switched over to a 650 Watt PSU (I used the 600 Watt for convenience of 2 12volt rails for my GPU). The problem then had been fixed, but now, with the new PSU, I can't even get more than a second of boot - I don't even hit the BIOS page.

    I'm not too sure why it did this at this time, as I have had Dragon Age (among others) for quite a while and my computer is more than capable of running it for days on end if I wished. Any insight on what may be going on will be much appreciated! :D

    If I need to post any more information, give me a shout and I'll respond as soon as possible! :D

    Are there any LEDs on the motherboard that stay on? You could just check whether the PC boots using a separate PSU. If not, then it's likely that the motherboard is fried.

    The Green Led which indicates that the board has power (SBPWR) stays lit, however, when I switched PSU's, I had a different effect. One PSU had powered everything but gave my Video card a d1601 error, inhibiting me from viewing anything on my monitor. The other, however, gave me no power at all. This I do not understand however, I am working on getting it ran into a specialist shop. However, as you have said, there is fear of the motherboard being fried. Well, its been a good six years with it, I guess I'm going to have to see if it can be fixed, if not, an upgrade will be needed. Thanks for the reply! Sorry it took so long for me to get back to you too, its been much fun getting my classes set up so that they collaborate with college ones as well.
