Hi there eddiehazel,
Firstly, welcome to
CompuForums. I hope that you can visit our forum often in the future and post - rather than just receiving our help and advice, and then never visiting again. We provide our help for free, and all we ask in return is that you participate in our forum and refer your friends, or consider a premium membership.
The best thing to do would be to reformat the computer [and install some decent antivirus software as well, other than the default Norton / MacaFee]. Do you have any of the original disks that came with the laptop?
