Hello. Got that issues since few days. System restarting itself. I have checked windows logs and found that RPC is doing that for some reason. So i have tried to change the options in Remote Procedure Call in control panel. But all the options are grayed and and i can't do that, even when im administrator. I remember i did that in Win Xp and Vista but cant do it on Win 7 x32. I wanted to change option, so he doing nothing if he find any issues. Restarting system is so annoying. Any advice is appreciated.
