I am not sure about hardware in this case. It sounds more like something running in the background causing processor overload. Did Gateway install any new software? Does it completely lock up or does it eventually come back?
About 30% of the time, if I don’t try to move the cursor much, it will return.
The rest, locks up.
I’ve assumed that . . . others . . . have stuff on that watches keystrokes or some such but I have good antispyware etc.
Gateway may have installed some locks on 2 extra hard drives designating them only reserve reboot drives. Sigh. Have yet to fix that.
