i have a copmuter my dad made like 4 years ago. cost him in the thousands (in those days like 1.5 GHz was fast!) its a 1.3GHz processor and dont know mobo. i got the comp. overclocked it to around 1.43 Ghz, replaced PSU, RAm, and CD drives. been 5 months. now that i run IE for a few hours it just closes, no error screens or anything, while im still using it! it gets pretty annoying...
