CMOS ERR

[DUDE9087]

so here is what happened, me and my buddy are in the military and he let me borrow his computer while he was gone for awhile. It couldnt be more than 3 months old, built by him. So i Hooked it up, and turned it on. While i was plugging the audio in i accidentaly hit the clr cmos button. Now when i try to boot it back up, the lcd poster says "cmos err". I'm not even getting a boot screen, it just says "no sync signal". Can someone tell me what i can do to remedy or if i just f***d something up big time.

If you have,, or can download the manufactures manual follow the cmos clear procedure,usually involves removing the on board button battery and resetting the cmos,,,,again,other than that ????...
