What service pack are you running?? Are you using dail-uo or broadband??
If you're using DSL/Cable You should run an online VScan http://housecall.trendmicro.com
would be a good start.
Have you checked your device manager for bad hardware?
This might be a virus / malware on your system. You might want to post your problem in the software section.

 

I am on SP2 and am on broadband, how can i use device manager to check for bad hardware and i find some what do i do about it.

 

By use device manager to check for bad HW, he merely means when you open device manager do any yellow ! show up beside some of the icons.

Another good thing to check is temperatures. Get a program to check the temps on your CPU to make sure it's not over heating and causing the crashes.

 

Yeah i think i may have sorted it I believe it may have been the temperatuire of the cpu overheating it, as after a friend told me to check it turned out the start temp was, 49 C and then after it had crashed it was 72 C so that is what i have come to conclude i am buying a new fan as soon as i can I will let ya know if it works.

 

check the event log? in control panel, admin tools, event viewer

 

thermal paste spread very finally too
