I am very confused, my pc went under some reconstruction after i had to install a new psu, i have had some problems when i installed it, and got it to work.

It worked for about a week when all of a sudden it turned on for about 3 seconds, then turned off...i was very suprised about this because it worked fine earlier in the day....then after 5 more seconds it turned back on again.

Now it stays on, and all of the fans are running fine, the video card is working and everything seems normal. But the monitor does not respond, nor does my MERC stealth keyboard luminate.

Any ideas on what i can do...and reminding people that it did work fine before

this seams to me like a BIOS issue. when something is wrong in the bios the computer will turn off and on repeativly in an attempt to reset the bios. this is a common feature in newer motherboards. did u tinker around in the bios?
