My laptop has been the best, trouble free computer I have ever owned. After 3 years, it is now showing its ass like my old computer at 1 year old. It is slowing down a lot, pop up blocker only catches some of the pop ups etc. I cannot afford a new one. I am running Windows Vista (yeh, yeh I know, but that ain't the problem). I use Firefox browser and Avast virus protection. This has just started lately, and I do not think it came with a reboot disc. I can't find one, so I don't think it came with one because I am anal about saving that stuff. How can I restore, reformat, make like new again or is it forever lost? I can deal with it if I must, but it sure could use some help. I have run the disc cleanup on it regularly and also used a program called C Cleaner. Gurus, any ideas? what about Ubuntu? How do I clean this one up and install it?
