Hello,

I was using my computer, and suddenly my computer froze. I waited about 3-5 minutes, nothing. I pressed the turn off button, and held it for 3 seconds. I tried to turn on the computer, but the lights on the mouse and keyboard are not on. No input from monitor; "No Signal" message. I plug in other devices such as a usb hub, it received power (the red light was on). Fans are turning, the green light on the motherboard, dvd drive working, so is the hard drive. i did install inner devices: 256 mb ram and a network card, but the computer worked perfectly with them. the bios battery reads 3v. the computer is non more than 3 years old. Please help.

when we see 'no sigenal' it means there is a barrer between cpu and moniter link .ithink your cpu is working properly u can chek on another monitor. your vj wire or its pin may be damage look seriously. if wire damage elcronix tech. can corret it.
it worked just fine, then it froze... if it some thing with the motherboard, wouln't some usb ports not recieve power?

i just got the exact same problem :(:(
found a fix for yours yet?
Solution:
Motherboard went bad. I replaced the motherboard for as low as $250. You'll get a higher price if you need a better motherboard. How did it go bad? Don't really know. Several of my guesses are(in order of probability):
1) Static Electricity when I was upgrading the computer. It was possible that one of the screws that hold the Motherboard weren't firmly screwed in, resulting a touch with case, and a shock.
2) Old motherboard (5 years old?!)
3) It didn't want live.
