Re: Packard Bell B2218uk Problem
Hmmm. It's not possible to be certain with a fault like this but my best guess would be a failed motherboard. There's a slight possibility that it could be power supply failing but it's a tough one to diagnose remotely.
It may be worth trying a pull and remake on the system. With mains disconnected remove all items slotted into the motherboard such as ram or graphics card, brush out dust and crud from slots and refit. Check all cables are firmly in place, both power and data before trying to power on again.
If that fails I'm afraid it will need expert diagnosis.
