Re: What would cause my comp to always just lock up at random times?
Are you getting any beeps when it locks up? if so check your ram like Raffaz mentioned, run a program like CPU COOL for a constant time like 1-2 hours just to see if you computer temp does spike at all, also take your side case off and clean out any dust inside your tower being careful not to scratch your motherboard circuits, clean your CPU fan and heatsinc as well, if after all that its still playing up then try running your Anti virus and spyware programs to see if you have any nasties, if no try checking your graphics card.
