Hello roc64, Welcome to the forum try this; http://www.sevenforums.com/tutorials/700-system-restore.html If possible go back to a date b4 the problem started

good idea

lol i dont know when it really started but i know when it got annoying thanks thou
maybe if event viewer where made more like other windows program search it would be easier i still dont understand no right click option on event viewer but hot keys suck for a reason there to many of them to remember but i will do some research and try to figure out the date thanks man
