Is the laptop well maintained?
That is, you give the vents a blast of air every year to expel lint and dust bunnies.
I have a Toshiba Satellite M35X-S349 that is very sick. It runs Windows XP Home, with a Intel Pentium M processor 735, 80GB, 512MB laptop. I had been having problems with it being slow, so I decided to reformat the harddrive, which I have done a couple of times before. This time though, it was in the process when the power went out. The power to the computer wouldn't stay on long enough to quickly finish. It would start, then crash. Finally I got it going, then the dreaded blue screen came up, when I turned it off and back on. It would finish running chekdisk, load, then crash. Blue screen again. Same thing over. Now I can't get it to stay on long enough to load. I bought a new power cord, thinking that may be it. It wasn't. The laptop is 4 years old and in constant use until now. I hope someone can give me some idea of what is wrong and if it can be fixed without costing me a lot. Thanks.
