The screen went black. The computer will not power up.


suspect a failed Hard drive or a fuse for the power supply unit
some have a small fuse near the power cord inlet socket
if the power supply fan is spinning, then it most likely will be a HD

My computer went blank when turning it on


1) Computer isn't working, due to the Processor isn't working, due to a bad Power Supply.
Weak voltage power rail.

Enough power perhaps to light LED lights, and maybe spin fans, but not enough power to turn the Processor on.

Computer Power Supply's are rated in Wattage.
Volts times Amperes = Watts.
(Average computer power supply in a fairly new computer, is rated at around 300 Watts)

A) ALL of the LED lights combined, use less than 1 Watt of power.
B) EACH fan uses 2 to 3 Watts.
C) A typical Processor may use 51 to 125 Watts.
Depends on what Processor it is.

Power Supply with a weak voltage power rail, can have enough power to light LED lights, spin fans, but not enough to turn the Processor on.

Solution?
Test the voltages of the Power Supply,

Or, use a KNOWN to be good Power Supply, that has the correct amount of power cables, the right kind of power cables, the correct size, and shape of the case, and enough Wattage, for a test unit..

A bad Power Supply is one of the leading causes of computer failure.

The computer does not turn on


First--does it do anything at all? No lights, no fan, no hard drive spinning up?
No?

Then your power supply most likely is bad and must be replaced.

EMachines T2824. Does nothing but light on mainboard coming on...


This is a motherboard problem. You'll need to replace it. Although, it may be cheaper just to buy a new PC (eMachines are never very expensive, or well-made for that matter)

Tower will not turn on


I am in no way an expert on computers but after hours of research, of course starting at fixya.com, and trying everything short of buying power supply and motherboard, i found a post that suggested to use a blow dryer and blow hot air over the area with the blinking light for about a minute. I was really reluctant to try this but am glad i did. In less than a minute i could hear the comp powering up and the light went and stayed solid, so far that is. I always use fixya.com for everything and wanted to put what helped me on here in case it can help someone else or save them hours of research. I hope this help some. Good luck.

No power light when on but can hear running, no screen image


First make sure the monitor is on and connected to the PC.
If the power light is not on you could have a bad power supply, it could also be that the onboard video went bad.
If your PC has four trouble lights in the back, let us know which ones are lit, this can pinpoint the problem.
The noise you hear is the drive spinning up and the CPU fan.
Good Luck.

Hello, My name is James. I have a problem with my 2050 GB Toshiba External Harddrive(Cypress AT2LP RC42). My copmuter can't reconaise it no longer. Can you guys help me out?


Check the power supply. Re-install the drivers if applicable. Can you hear the hard drive spinning, does a light come on? Also try a different cable from the device to the computer. Go into Device Manager and see if their is some info there. Check the bus that it uses (USB, Firewire, etc) in Device Manager. If you know how, remove the hard drive from the case and install it on a bus inside the computer case. If it works this way you know the problem is with the external case or power supply.

I went to turn my pc on and the hardrive hase stopt spinning wot do i do


if you see no lights on at all, no fans going or any sign of life, it may be the power supply that has died.
if you see lights on but the pc does not boot up (turn on) it could be one of many problems , we need more information
as it could be:
  • bad cpu
  • bad motherboard
  • bad memory chip
  • bad hard drive
  • fluctuation power from the supply
as you can see more info would be good, as that is the only guide we have .

good luck
