>>no post,no beep,lights up<<

What lights up?

Was this a sudden failure, or were there problems before it died?
Did you install or remove something from the motherboard? Card, memory, etc.?

>>i tested a bit and found a mosfet that has no power<<

Please explain what you did and how you determined that.

Is there any obvious physical damage to any components? Crack in MOSFET case? Blown caps? Discoloration of board or components? MOSFET looks like it slid off its mounting pad?

sudden failure (wouldn't boot). no post, no beep codes. all fans spin, and the hard drive spins.
tried different ram,video card and tested cpu in different board.
no caps look bad. i heard mosfets can blow and cause similar problems so i tested all of them with a multi meter. all showed voltage except one.

Re: asus m2r-32mvp

Try a different power supply. What PSU is in there? Brand/model?

If there is NO voltage on the MOSFET, then something feeding it is not working. If there was a short, I would think the PSU wouldn't even start.

Caps may appear physically fine, and be completely bad.

How old is the mobo?

"lights up"
In some parts of the world that means the same as "powers up" or "has power".

I'm sorry. I wasn't lit up.

i have tried several power supplies. board is 2 years old. oh and "lit up" means the power led on the board is lit.

RMA it back to ASUS.

Re: asus m2r-32mvp

Sorry for the late reply here I had a board like this one given to me to take a look at. All the caps and mosfets read ok so i tried resetting the bios well I thought i did anyway. As I said I thought i reset the bios moving the bios reset jumper for a fewseconds then moved it back.

This mother board requires you too
1) remove the power lead
2) remove the the cmos battery (I didnt do this part at first)
3) move the clear cmos jumper for 5 to 10 seconds.
4) Move the jumper back over to default position
5) put the vattery back in

After this the board came back to life. It might not be your problem but it fixed my problem. The problem happened when i changed my old dvdwriter with a new one. It must have done something to the cmos to stop the machine booting. I hope it something simple like this for you too sometimes its the simple things we miss.
