RAM - how do I check RAM? Physically or 'PC' checking?

It could be nothing is running and it still happens.

There is no pop-up advising MS - it is either OK to terminate, or CAncel to debug, which then just freezes the pc up.

PC is not over hot, and occurs as soon as it is turned on.

Anti-Virus (AVG) & Spy Ware (MS & Adaware) both run OK
