I have an online friend who's computer randomly keeps freezing on him for a few seconds. When it happens the CPU cycles go up into the 90's (aka 91% or something similar). Anyways, I've started to diagnose the problem, but so far I'm not sure what is causing it. I have checked his startup items, and so far none of them look like they would be a problem. (Except I have no idea what reboot.exe is for) I have attached a screenshot of the startup items. He has run an antivirus check already. (probably several times -- I'm not sure) I've asked him to run adaware -- he plans to do that sometime soon. I've also asked him to keep an eye on the processes for the next time it happens - if I can catch the process in the act this would greatly help. Does anyone else have further suggestions for things to check or some programs to run like adaware?
