no power to monitor or keyboard

  hargranules 18:24 27 Aug 2006

hi trying to mend my mums pc, packard bell windows 98.

When pc is powered up the monitor remains blank and there is also no lights on keyboard. Standy - by lights are on monitor and Pc makes normal noises, like it is booting up. If i put a cd in I can hear it spin.

Tried a different monitor but as i say no lights on keyboard either.

Any ideas????

2. remove and refit graphics acrd and reboot.

No Beeps probably you need a new PSU

Don't mean a thing when it comes to powering up Hard Drives etc

PS the Mobo could be gone but PSU is cheaper to try first

At present I have fortron / source model no: fsp235 - 60 gi

Looking on net i found that atx 300w replaces it as long as i check dimensions.

Anything else i need to check before i buy?

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

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.

Symptoms sound similar to what happened to my computer a few years ago. Found out that the modem was faulty.

If it has a modem remove it and try rebooting again.
