Okay... I'm in a serious pickle here. I just went into my BIOS and tweaked my NB to 2600 from 2300 to match the HT @ 2600... Also I changed my CPU Auto Fan to disabled so it would run at 100%. Upon saving, the PC auto rebooted as usual but this time my monitor is stuck in sleep mode. It's not even giving me a "NO SIGNAL" error. I've force rebooted about 15 times to no avail. Let it sit off for 15 minutes, nothing. Let it sit on w/o monitor working for 20 mins and nothing. Changed from DVI to HDMI to no avail. There was one time I got it to turn on (after unplugging power and switching off power switch) but it was stuck on the GIGABYTE Splash screen where it shows the hotkeys. No keys responded. I can hear the CPU fan that changed to running at 100%, all other fans running, but it still won't boot up. No typical Windows login sound either... Anyone have any ideas? I really wouldn't think a NB Tweak or CPU fan adjustment would cause it to freak out like this and especially not blow the CPU...... Really confused here. Is a CMOS reboot in order here? Anything to get this thing running again... Just started Arkham Asylum and GTA IV.
