sounds like mobo just took a dump on you.
First off I want to apologize that I don't have my system specs. listed (at work). I can come back later and post or put in my profile later.
My problem is this; I powered off my comp. before Thanksgiving and when I came back on Sunday, I powered it up, started playing WoW and the computer crashed...all the way to OFF. I rebooted the machine and I loaded windows (Vista Ultimate) in the Safe Mode...crashed again. After that, I couldn't even get the comp. to boot to the BIOS. After resetting the CMOS switch, pulling and reseating the Video card, sound card, all 4 gigs of RAM and all cables, I still can't get to the BIOS.
Instead of ripping out the Mobo and sending it back, I'm trying to eliminate other possible causes. After reading many threads on this board, people tend to lean towards the PSU. I've got a call into the Vendor ATM to walk me through the steps of putting a multi-meter on it to see if that's the culprit. I tend to think it's not the PSU because all (4) fans come on with all the lights. But my ignorance in this field may cause me to think wrong.
It's an nForce 590 SLI board and I'm getting the LED code error of : 02. And the machine does not BEEP when it tries to boot. The techs at XFX couldn't tell me what the 02 code meant .
Anyway, these forums seem to be hopping with good support, so any help would be greatly appreciated.

Make sure the CPU heatsink is securely attached.
Remove all but 1 stick of ram, try and boot, if no love, switch that 1 stick for one of your others, and repeat trying all sticks.
Tks for the info so far. I now have sys. specs. in profile
I'd unplug all internal components except your CPU...and power up each time..see if you don't get the beeps. If no beeps or errors...start replacing components 1 by 1...vid card....RAM....hard drive...etc etc.

My bet is on the PSU, I have had clients bring me pc's that they have tested the PSU with a mutimeter and said it was good, I have a $20 PSU tester that said they were bad, replaced the PSU and everything worked perfectly. PSU go bad all the time, I would recommend Cooler Master PSU's such as the COOLER MASTER eXtreme Power RP-600, high quality that won't break the bank.
Again, thanks for the replies. I think I've decided on returning something (since everything is still under warranty) and I'm going to start with the Mobo. What if it's not the Mobo, will vendor just send it back and tell me it's good then I proceed to the next thing which will be the PSU and continuing returning stuff until problem is solved? What vexes me is there are computers that can diagnose a car and other devices. Why isn't there a device you can plug into a computer to check everything and say "Hey dummy it's your Mobo"?
Have you tried any of the suggestions?
Also, try a different known good video card.
Video is the first thing checked in boot up, and it seems it's not booting past that check.
Just a hunch....
I had exactly same problem couple weeks ago ....RAM was bad, both sticks.
I would try different RAM, borrow it from your friend, relative ...someone and see.1 stick will be enough.

It was the motherboard. So for future reference and to help anyone having the same problem I wanted to update thread.
Thanks for this Thread, I'm having the same issue though in XP pro.
It just Froze up, if it was playing and sound at the time it would loop the last note really fast.
This happened a few days ago and I rebooted fine then it got worse where to the point it wont boot.
Did the usual reset Cmos, removed refitted components, all lights and fans work fine.
It's a new built I put together about 2months ago, so I'll test the PSU on my other PC and send the mofo, sry bo back.
I'll let you know you if it was the same issue.
Mine too, send the board back and had a credit within 1 day, I think this is not the first time they have problems with this board, because in the clearance section they have about 7 of this model which tells me they've had repeated problems with this board (MSI P6N SLI Plat). so I go this one as a replacement: Asus P5N32-E SLI Plus
Anyway, keep this thread alive as it was a big help.
My configuration is:
I have already replaced the motherboard and still same thing. I looked at PSU and in the main power connecto4r 20+4pin there is an empty hole and no metalic thing like in the other holes. Is it bad or did it just come that way. I looked online for pixs of it but found nothing that would show it.
