Desktop Computer Dead Help !!!

  Wirral Bagpuss 00:42 19 Sep 2009

ARRRRRRRRRGH !!! My computer wont start. it was fine this morning but now it is dead. No power, nothing. The monitor is fine. I switched power cables and that did not work. So i guess it is the computer itself. Any ideas as to what has caused it not to work at all? Can this be repaired or am i going to have to buy a new pc? I have stuff on that PC that i need to get back !

Can anyone offer advice ?

have you checked the fuse for a start?

I would look first at the PSU . fairley cheap ( under £50. ) and replaced fairly easy

Thanks for your replies. I did change the plug/cable to the PC so i know it is not the fuse in that. That was the first thing i thought of ! Still no joy. No beeps or lights, nothing !! What is a PSU? I am waiting for the computer repair shop to collect my PC and hopefully fix it. They said it might need a new power pack which they can fit for roughly £35. Not too bad. So if it is not that what else could cause it to die on me ?

I am so glad i have my laptop but i do hope my PC can be saved as i have so much on the hard drive. I know i should have backed up. I was going to invest in a portable hard drive for that purpose actually and then this happens... *cries*

£35 and fitting that's a cheap PSU that might not last that long.

If renewing a PSU check:

1. The physical size of your PSU, some are hard to replace due to being a non standard size.
2. The amount of power need from the PSU don't skimp.
3 The correct connections for your equipment

1. Physical Dimensions

Besides the specs and form factors, the physical dimensions are also important factors in selecting a compatible power supply. Here is an outline of the physical dimensions of most standard power supplies:

# ATX: 6x3.5x5.5", HxWxD. Most common. Uses 4 mounting screws.
# Mini-ATX: 5x3.5x5", HxWxD. Rare size. Uses 4 mounting screws. Can be used in a regular ATX case, but often not the other way around.
# MicroATX: 5x3x4", HxWxD. Use 3 mounting screws. Not interchangeable with ATX or miniATX.
# Flex ATX: Even smaller than Micro ATX. Various sizes according to case specs; often not interchangeable.

Use the data above to determine if a particular power supply would fit your case.

The quality of a power supply can be estimated by its weight. While this is not a true scientific or thorough measurement of the power supply reliability, it is nevertheless a very simple and easy way for ordinary PC users to estimate and compare the quality of a power supply.

3. Correct connections
Some boards have 20 pin connectors others 24 pin
There is often a 4 pin plug required to power Intel CPUs
Molex D plugs for IDE HDD and CD/DVD drives
SATA power connections for latest HDDs and DVD drives.
