Troublesooters!

1.Overview of the problem
--------------------------------------------------------------------------------

Computer simply won't turn on.



2.Full description of the problem and symptoms
--------------------------------------------------------------------------------

I built this system about 10 months ago and it ran like a champ. No OC'ing, nothing out of the specs. It literally was fine when I left (on stand by) and when I returned it was dead. I hit the pwr button - nothing....no fans, not even on the pwr supply.




3.Did it work normally at one time, or has the problem always existed?
--------------------------------------------------------------------------------

Rock solid for 10 months. Nothing new installed (the last thing I did was bring a folder of mp3s from a jump drive onto the desktop - hadn't even peeked inside yet.)



4.I already tried these steps:
--------------------------------------------------------------------------------


Took the RAM and the pwr supply to Fry's and asked them nicely to check them out -both were good.

Outlets good too -and all the switches in the 'on' position. Also checked to make sure I was getting contact (pushed in all the cords.)


5.My software:
--------------------------------------------------------------------------------



◦Windows XP Media center Edition with everything up to date

◦Don't think other software details would be relevant to the issue

7.Other information that might be relevant
--------------------------------------------------------------------------------
I've already established that the PS is not the issue (and already tried another PS just in case Fry's was wrong.)

I have another mobo but it's not compatible (and neither then would the cpu be.)
