Hi Jelly Bean, thanks for helping.
I don't know what graphics card I have so I used the Belarc Advisor but under the 'Display' section it said "None detected".
It stopped working after I re-installed Windows last year.
I have a Compaq Presario 2500 laptop which runs on XP Home SP2.
The graphics driver I need is the ATI Mobile Radeon but there's so many different versions that I don't know which one to get.
Any help anyone could offer would be really appreciated as I've had this problem for nearly a year.
If anyone could give me a link that'd be great as the website I found confused me.
Thanks
