I was on my computer this morning when sudenly it shut off. At first i thought it was because i had set my computer to turn off the hard disks after 30 min (sometimes i leave my computer on during the night and after so long it is done so i have it turn off the hard disks) I had been installing a pretty big game so would have been idle long enough. I also saw that green light near the power button flashing. It all seemed like the hard disks turned off. When i tried waking the computer up nothing happend. The light stopped flashing after a while. My computer wouldent turn back on. I tried for 5 min do everything i could. Finaly i looked inside the computer and a little green light is on, on my mother board. As allways it is glowing. After a few tests i notice when i plug my computer in (or flip the I O switch to I) my CPU fan twrils a tiny bit then stops. The same happens when i press the power button. My brother says it is power supply problem and i think it blew a fuse or something. Any idea on what happend?
Or what i could do?

The obvious thing would be to borrow a different PSU and test with that... but if that isn't possible then try getting hold of a multimeter and testing the outputs on the PSU lines (12v / 5v 3.3v etc...)

Also try unplugging all drives so that the PSU is just powering the mobo just incase it is an overload problem.

4.77MHz to 4.0GHz in 10 years. Imagine the space year 2020 :)
