Dell c521 won't start blinks amber


A possible power supply failure has occurred. The system has not received a Power Good signal from the power supply. In other words you either have a defective power supply or a device in the computer (i.e. sound or video card) is shorting out the power supply.

I have a emachine that powers ou, power pack fan, cpu fan but not the hardrive. It shut down and now won't start up. No beeps


Unplug from AC, open the case, clean if necessary, reseat the memory mods, use Electronic Contact Cleaner spray on contacts, plug in, push the on/off button. Does it begin to start, and in a few seconds completly shuts down? No LED's , no fans, nothing? Sounds like a PSU failure. Mine went out in 6 years.

My dell inspiron 1545 won't shut down went i click on the shut down icon it won't turn off .


Hold down the power button for 10 seconds. That will hard-shut the PC. Once that is done, fire it back up, and try again. Somethimes, windows will act goofy shutting down. Especially Vista when it is left on too long without shutting it down.

My Medion MT6 desktop has developed a problem. When I power it up, the fans power up then shut down immediately. They then power up for a couple of seconds longer, then shut down. The process continues...


take it into a computer repair shop for a proper diagnosis
could be a faulty power supply or failing mother board
check that the power lead is properly connected top the pc

What will happen to the hard drive in power failure?


Power failure as in whole house power failure? Or the computer's power supply failure?
Whole house failure, nothing, the computer will shut off and require rebooting, at which time you may receive a message the computer was not properly shut down, just continue as normal.
Computer power supply failure, same thing, nothing, except the computer will not reboot as the power supply has failed.
