I am new to this scene and built my first machine. Coolermaster Cosmos, Q6600 GO revision with Zalman 9700 cooler, Asus Striker Extreme mobo, 2 8800 GTS 640 mb in SLI, seagate barricuda HD 1x 750 gb for media and 2x 320 in raid 0 for vista 32 bit and games. My problem is that all was running fine until I was messing with the Asus provided AI tuner tool in windows. I increased the fsb to 296 and had 2.66 with no problems and all was running fine. processor temps were 37 degrees while playing Half life Episode 2. I made another small adjustment in the tuner to 306 fsb and it locked up. The mobo manual says that rebooting using this tool returns the default settings. I checked the bios and all settings are at there original settings. However upon leaving the bios all i get is a black screen and the hard drive and power lights go off. All fans are still spinning and the computer is still on. I know I screwed this up as i am a total newbie to this and need to do more research on overclocking and not listen to the manual when it says just reboot. If someone has an idea on how to get this back to the stock settings and run as it was i would be greatly appreciative. Thanks in advance for all your help and I look forward to learning alot from all you guys in the future.

Even though the settings under BIOS are back to standard settings, I would try taking the battery out and clearing CMOS and start over again. Just to make sure that the simple things are out of the way first before you start taking hardware out and swapping.

on the bottom area of ur motherboard their is a 3 pin with a conecting bridge on two of them. switch it to the other side and turn on ur comp, it should reset ur bios to factory setting then sav e and exit wait 3 seconds after u leave then instantly turn off ur comp, switch the plugs bak over and ur good to go

Please do not ever use anything to overclock from the OS. Always do it from the Bios. I've read many and so many bad things happening due to overclocking from the Os.

I think Gigabyte is the only company that makes good overclocking software.
