smeghead103, thank you for your e-mail, sorry for the delay in replying to you, but I have been busy today. This is the best place for help though as many more people will see it and there are some far more knowledgeable people here than my self.
What exactly is the error message you get on bootup? You may be able to download a driver or fix from the internet.
Is it win 98se that you are using? post back with more details, also if you are on 98, then press Ctrl/alt/delete keys together and see how many programs you have running in the background.
Have you emptied your temp. files recently and also cleared out your Temporary internet file folder.
In the sys.tray, lower right of screen, where the clock is, how many Icons do you have in there? That should keep you going for a while, post back with answers to these questions, and I will see if I can advise further.
