Hi guys, just to add to this... I had exactly the same problem and tried the cmos wipe method (which I came across first) a bunch of times to no avail. This method worked the second attempt. But when it worked the pc just kept beeping, didn't restart, and next time I turned it on it was all sweet... so if this method doesn't work, keep trying with slight variations until it does! Edit: changed a setting amd it's beeping at me again. Guide above not working tjis time... either beeps 5 or 8 yimes. I'll post my solution if I can get this working again. Amazed that this thing doesnt auto reset cmos on boot failure :s Edit edit: further to this I got it working, but had to remove the cmos, and battery etc, hold power 45 secs, put all bk together except battery then power on whilst holding fn. This gave me 5 beeps... so I turned off and on again and it was all good... fun! I'm trying to disable the intel graphics fyi.
