computer just turns off

[argoldst]

I had this problem before (about 2 weeks ago) where it occurred for about 2 days but didn't happen again until now. I cannot get it to repeat iteself so it is very hard for me to troubleshoot.

My computer just turns itself off and will not turn on again (or turns on for about 3 seconds then turns off again).

I have tried to make sure all the cards/ram are seated right and they seem to be.

Once this happens, if I hit the power button sometimes nothing happens and other times it will start up and last anywhere between 1 second to 5 seconds. (it doesn't even get to load up windows).

It is not temp as I just turned on my computer this morning and it was off all night.

My system is:

535W Enermax power supply
amd 4400 cpu
asus sli premimum mb
2 1 gig ocz platinum
2 xfx 7800 gtx in sli
hitachi sata II 500 gig hd
creative x-fi

Any ideas? I have a three year warrenty with monarch (but I do not want to send away my computer for 2+ weeeks).

All I can think of is that it is a problem with the PS, mb, or case (with a short somewhere). What do you guys think? Is there anyway to narrow it down to find the problem? If I can, I can just rma that one part and only have a short down time.

Please help.

Thanks.

Looks like a very good system.

My first guess would be a minor problem with the power supply. Might try another if that is possible - would have to be a fairly high-end supply to support that hardware.

But first you may want to investigate the seating of your heatsink on the processor. You may want to call Monarch for their instructions on whether to try this yourself and if so, how they would have you go about it.

Also, did you try taking out the CMOS battery, wiping it off with a very soft cloth and then reseating it in the socket ?

You might consider resetting CMOS via motherboard jumper but I would not do this unless Monarch suggested.

Good luck.

Sounds like a major problem with the power supply. Contact Monarch.
If this is your psu it should be more than adequate for your system.
