Please, please, please help me. My new computer is having a very strange problem ever since i put on easy tune pro 5.0 and nVIDIA nTUNE on it. I put these on it because i was getting strange flashes of white across the screen when i was playing games, which ultimately kept crashing my games when i was playing the games. So i thought it might be a graphics card problem (i have a nVIDIA GeForce 7800 GT). After i got these i went on them had a snoop around them and then when i went onto Easy tune and some weird thing said motherboard fan going into cruise mode - you must restart computer i so i exited that pop-up and then i went to bed. the next morning i turn it on and it freezes at the logon screen. so i restart the computer and it does the same at the windows bootup display. So i am getting confused and i restart it again goes to the very first gigabyte logo (i have a GA-8N-SLI PRO motherboard) and it freezes. so i hold down the on button and turn it off. i check the wiring and all that - nothings wrong here, so i turn it on again does the same thing at the windows bootup display (freezes) so i restart it again and it asks if i want to go into safe mode and i try to move the highlight up but the keyboard isn't working! so it automatically goes into normal mode and it gets to the logon screen and it hasn't freezed yet but the mouse and keyboard don't work. i reconnect them to different usb ports and all that but still nothing! So i use an adapter so i can plug them into the ps/2 ports - the lights flash on the keyboard a couple of times (when booting up gigabyte thing and when booting up windows) but they still don't work. so i am really in need of help, please help me.
