Power outage, now pc will not power up at all.

The problem is the power supply it will need to be replaced.

HP Support & Drivers

It sounds like you have a board that is not booting at all. Remove everything from the board except the system RAM and CPU and switch it on. If it boots now, shut it down and then replace each individual item one at a time, booting the machine after each item is refitted/connected until you fit something that prevents the machine from booting. Pay special attention to system RAM sticks by removing them/it and refitting it as bad connections in the RAM socket can also cause a boot failure but removing and refitting the sticks usually cures this issue.

Sometimes when this happens the motherboard shorts out. You will need to replace that.

On HP computers, I believe that this means that the power supply or the motherboard is bad. I assume that the outage was due to the thunderstorm and you may have received a surge. In your manual, there should be diagnostic light codes where they will outline the exact meaning. Again, to the best of my knowledge, this means that there is a bad power supply or a motherboard.

hello there

as silly as this may sound, have you checked the fuse on the PC power lead.

Many thanks

OK FIRST A POWER SURGE PROTECTOR WILL ONLY PROTECT YOU 7 % OF THE TIME, WHICH YOU JUST REALIZED. SO YOU NEED TO BUY A BATTERY BACKUP ALSO KNOWN AS A UPS.... I CANNOT STRESS THIS ENOUGH. BRING YOUR PC TO BEST BUY AND THEY WILL TEST YOUR POWER SUPPLY, IF IT TESTS OUT OK THEN YOU BLEW SOMETHING IN YOUR MOTHERBOARD. GET A BATTERY BACKUPS/UPS!!!!!!!!!!!!!!!

You media center have a hardware error. If you know how to open your pc, open it, remove the memory of your pc and reconnect it.

if you can open your desktop..try to replace the ide cable of the DVD/Cdrom it might be deffective.before you open your pc just make sure that the power is off.after changing the ide cable of your dvd the system will automatically detect your drive.if you got same problem again try to consult your hardware vendor to claim your warranty parts and service.good luck
