"After I pressed the Power button..."

Nothing happened
• Check mains plug switched on at wall
• PSU may have its own power switch - check this is on
• Check PSU-to-Motherboard cable(s) are correctly connected
• Check front panel power switch is correctly connected
• Check Reset button is not stuck 'in'
• Check mains cable fuse

There was a loud bang (possibly with smoke) at the back of the PC Case
PSU was faulty or set to incorrect voltage for mains supply system. Replace PSU.

PC is on but monitor shows no display and a sequence of beeps emits from the PC
·  Check fitting of CPU, RAM, Video card, sound card etc. If necessary, remove and refit these components
·  Check the motherboard manual and perform a BIOS reset procedure
·   This may indicate a faulty motherboard.
