hi! i'm a techspot newcomer, and i'm posting here my first problem.

I have a quite old acer aspire 1300 with win xp home installed. When it was new, it worked good. but since last year, it started slowing down. so i formatted it, and reinstalled the os. but it is still too slow.
and then, sometimes it shuts down suddenly; i think it's an overheating problem, but can this even cause the slowing down? and if not, what causes it?

please, help me... thanks before

Overheating could likely cause your CPU to throttle, which, in essence would slow things down yeah.

If you feel that's what the issue might be, take a can of compressed air to the inside of your laptop .
