Is computer clean now?
It doesn't seem like it. Still takes a good 10-15 minutes to boot up and then actually be ready to use and is still very slow doing basic tasks (especially things like opening IE).
But, I suppose without showing you guys a log or something it's difficult to actually know.
It looks like I'll have to pay out and give it to someone to give it a proper going over... Unless you guys have any more ideas?
PS - I should add, it's 4-5 years old and has a poor 256MB of RAM, but it has only just started being so slow. Well, since I installed a wireless network adapter and Sky Broadband to be more precise.
I would like to upgrade the RAM but don't want to do that until whatever the problem is, is fixed.
Thanks again for all your help.
