Check the following in BIOS:

RAM Voltage against RAM manufacturers spec (e.g. 1.8V)
Timings against RAM manufactureres spec (e.g. 4-4-4-12 or just CAS 4)

If you are not sure then post back what RAM you bought. It's usually fairly easy to look up.

If those are set correctly then download memtesti86 (click here), unzip and burn to CD.
Reboot your PC with your CD drive as first boot device. This will test the installed RAM to make sure it isn't defective. Takes around 30 minutes.

If the first two checks above are ok, then feel free to post back with the specs of you mum's computer. It might help with determining the cause of the error.

how do i do the 2 checks ????

Depends on the PC. Most PCs as you switch them on will say 'Press(a key) to enter set-up' or 'Press(a key) to enter BIOS'.

Usually, but not always, the key is Del. Could also be F2 or F12.

What PC is it?

Where did you buy the ram?

Is it low or high density.

have you checked the manual to see what density of ram it can take?

Compatible speed, cass latency and voltage are one thing but if a machine will not accept high density memory, you've just got a heap of trouble.

how do find out about high denisty or low denisty??

  OTT_Buzzard 12:43 19 Apr 09

The memory you bought is the correct type, you now need to make sure that the voltages, frequencies and timings are properly set up in BIOS. Did you manage to get access to check?

Note: the above assumes that the RAM you bought is unbuffered, Non ECC.
