Unless compaq displays that message when the computer goes into sleep mode, it could be a virus.

Reset or Clear CMOS because maybe it hang-up some devices that are plug-in to. You can do that by removing the Lithium Battery on the Motherboard. This tips are only technician can do that but to solve your problems like this, this is a tip. And also check your Memory Module.
Hope this might help you, good luck!

Disconnect all devices from the power supply EXCEPT the motherboard
Remove any extra cards including video etc.(plug monitor into the onboard)

If you hear any beeps these can indictate where the fault is.
either of these sites below will help you further with that

Beep codes Pc

More beep codes

Power up the pc and see if the fans are working.
If not then double check the power connections to the board.

If you still have no fans it is time to suspect the power supply as the probable cause.

If the fans worked then you should have gotten a display which told you there was an error and offering you a chance to go into the BIOS. ignore it and shut down the PC.

Now connect one drive only and boot again.

Repeat that until you identify the component that is giving you a problem.

Once you find the problem then remove or disconnect and carry on with the rest to see if another component might also cause a problem

If there is only one problem device then you may want to investigate that device further, Unless you don't mind replacing it
