what's the temp of your CPU. Also if you can get ahold of another set of ram, try switching it out

"What kind of idiot are you?"
"I don't know, what kinds are there?"

my cpu is at about 40C all the time but since it's a T-Bird i think it's stanard

i don't have another stick to try out with but can anyone tell what's that program that can test if my ram is bad or not????

It sounds like it's encountering a problem with the registry, loading an older version of the registry, and rebooting off that. Have you loaded a new driver recently?

no i haven't been installing new drivers lately.... it started acting weird ever since i installed those patches from windows update......... also another problem is that sometimes when i try to open any program the computer say it encounter a error and closes it but if i restart it's back to normal really weird guess it's time to use the ultimate weapon .....
