Lately, on mine, I had been having some tcpip.sys errors. Basically, it gets you a blue screen and then the computer had to restart. Anyway, after upgrading my system cleaner to premium, it has stopped. However, I'm wondering if there was a connection. Anyway, I'd have to say that repairs on a computer, due to simple things, keep repairpeople with a job, but isn't good for your wallet and time.
