"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.
