Hi, I'm so maxed out. Bought a new Mach Speed motherboard with Celeron D 351 processor in it. I installed cpu, dvd burner and hard drive. The norm. When I get to first screen booting up and push DEL key to enter set up. I have to try and reset boot sequence or what ever I choose to edit. Must hurry because 2nd entry if not first before saving the bios locks up and I hav e to reboot the system. I tried reseating the RAM, CPU and all other components one by one. Tried different video card and RAM chip. Nothing is working and very frustrated. Hoping to get this resolved. Someone, please help and let me know if I missing an obvious something. I even tried a different keyboard and mouse and hard drive. Still no go
