Just built a new SFF PC (shuttle SB83G5) put all components together everything is plugged in and in the right place, been checking for hours, even put it together again, and every time i power up all fans and lights are on but no BIOS on the monitor, just says no signal, iv heard of this before and ive tried running the monitor off both the internal GPU and my 6600GT but to no avail, ive tried taking the battery out to wipe the CMOS but when i boot i get the same problem, im running out of solutions and starting to think ive broken something. Any help would be greatly appreciated. Thanks
