Computer turns on and off rapidly non-stop

[Zinic]

My computer is turning on and off (every second). It shut down while I was playing a game then this happened. It wont turn back on!! Lights on my case, motherboard and graphics card blinks during this on and off period.

I have an evga motherboard. What am I supposed to do???????

 

[Qdos]

Could be a worm of some sort... could be badly seated RAM or cards, could also be an inadequate or failing PSU for that matter...

 

[Zinic]

I dont have viruses. Computer has been running fine before. I didn't hit it or anything. So its not the ram. Failing PSU? But how? It seems fine.

we need more info. When did this start happenning? You say it turns on and off but then you say when it shutsdown it won't turn back on, which is it?

 

[Zinic]

It shut down then turned back on then off then on then off... When I press the power button, nothing happens. I have to unplug it. It just started happening like 5 min ago.

 

[Qdos]

Get your PSU tested, it sounds like it's giving up the ghost...

 

[tw33k]

Sounds to me, like qdos said, your power supply is either under powered or failing. Is there anything of interest in event viewer?

 

[Zinic]

It has been saying Power-Kernal-processor event ID 35 error. How do I check my PSU?

 

[Qdos]

Everything suggests PSU failure to my ears... you can get it tested at any PC repair shack, and even if it tests OK examine the power requirements of all the onboard components to see whether you might actually need a PSU with more juice than the one you're currently running...

 

[Zinic]

My PSU has been running fine for almost a year. It has plenty of juice. 650 watt.

 

[Qdos]

Everything runs fine until it starts to fail...

I've read a fair bit about that error and it seems to occur often with that particular mainboard and chip. Is your PC under warranty?

 

[Zinic]

OK it turned back on BUT.

When I turned it back on, it turned on for about 2 and a half seconds. Then it shut off. Then it turned back on again and the screen said "CMOS error, loaded defaults" or something. I entered the BIOS and exit it and my computer shut off again for about 3 seconds, then it turned back on. In Event Viewer, Everything seemed normal but for the critical error and warning error saying that my computer shut off expectantly. I still get those warnings: Event ID 35, Kernal Processor Error. I shut off my computer myself. Now its off.

EDIT: I don't think its under warranty. I built it.

You have a hardware failure of some sort (PSU or otherwise) We can't help you other than to say, unless you have the skills, to put it in for repair.

"CMOS error, loaded defaults"

Turn the pc off. Look on the motherboard for a circular silver disc in a plastic holder/container with a metal clip you can push on slightly. That's the cmos battery. Carefully remove it from the motherboard for at least 10 seconds. Place it back in and try to boot. Adjust bios if necessary but try to boot after putting the battery back in and not altering anything.

How important is this? I can't get it out. Too much cords in the way making it impossible to reach it with my hands.

Clearing the CMOS won't solve your problem. If you don't have the skills or the tools, you need to take your pc to someone that does. Seriously, you have a hardware problem and need to work out which component is failing

Probably the difference between a working machine and not. Do what you have to.

(We can pretend the post above me is not there and give this a real shot of being repaired easily.) Also unplug the machine from the wall while doing so.

Absolute nonsense and fiction. The CMOS battery will not produce the symptoms the OP describes, it's already been discussed sufficiently to show that the problem has shown every indication of being a PSU issue.

Depleted CMOS cells do not cause the PSU to shutdown spontaneously as the OP reports. A flat CMOS battery would not cause a five second delay in the PSU kicking in after the power button has been pressed either...

The reasons I would like the OP to try my suggestion out is apparently over your head. This is not an insult and is fact.

Could it be a faulty psu? Of course. I have never spoken against it. My attempt to do something here in this case is extremely simple and should be followed by all means.
