PC not booting? no monitor output, no usb

August 19, 2012 at 01:48:18
Specs: Win 7, AMD
I left my pc off for six weeks while I was out the house.

Now when I start the machine the fans start up and the disc drives spin up but it does not send any signal to the monitor and the USB devices do not power up.

I know there are issues with ROM corrupting if you leave a computer off for a while but I expected that you would have to leave it off for months.

Is there. Strange that in twenty five years I have never know a ROM to get corrupted through being left off. I have powered up computers that have been idle for years without a problem

There is a possibility of the CMOS memory getting corrupted because the CMOS battery has died but I don't think that is you problem here. If that were the case you would at least get something on the screen even if it was CMOS Checksum Error.

I would first open the case and reseat all the memory, expansion cards and connections and see if that work. These things can creep, especially if the computer had been moved about.


If that fails I would start looking at the power supply. The fact that fans spin and disk drive spin does not mean that the power supply is functioning correctly.

U didn't bother list the system specifications.
