Sounds like you have a virus or other malware infection

computer freezing

I also forgot to mention when i restart my computer a box pops up and it says error loading c:\windows\mshtonte.dll the specified module could not be found so what do i do to get rid of the problem

Are you in the USA?

yes i live in the united states

That error comes up as "nothing found" in Google. What antivirus and antimalware programs are you running? While you are at it, what are your computers complete specs?

i use malwarebytes,sybot s&d and avg 2012 also have superanti spyware pro but don't use it often specs are emachine EL300G-02w windows xp home edition with sp3 amd athlon 2650e processor nvidia geforce 6150SE intergrated 160GB hard drive 1GB ddr2 memory

This is an old eMachines so all bets are off... I suspect that the motherboard is failing. I have a 2 year old eMachines on my bench right now, it's motherboard was bad. It is up and running with Windows 7 and a new motherboard... sorry for this info
