It there malware about that will completly disable the BIOS and PC? The fans are working,the light is on but the hard drives are not spinning. Has my mobo died? Naesby.Good to be back on the forum.

not malware (although it can happen)

most likely PSU died, fans and LEDs require little power

more than one drive unlikely for both to die at same time although a dying PSU can take everything else with it.

To test the motherboard, disconnect all drives (Including hard drives, printers, USB's etc and try to start the machine. What you should get is the BIOS boot up screen, and then a message 'cannot find operating system'. If you get that your MB and BIOS should be OK, if so reconnect just the main drive and try again or insert (if you have one) a system disk and see if you get any response.

Check the CPU fan to see if it spins freely and there is not a build up of dust, also check memory (is it in firm) and look for any 'burn-discoloration' marks on the motherboard.

If all else seems OK the chances are the the PSU has died.
