Hello all,

I just got done building a new system. I have been building systems for 5 years and I have never run across this problem. I have the whole thing put together and when I turn the computer on I get the "Bios CheckSum, defaults loaded press f1 to continue or del to enter setup". This is usualy normal when you havent set any settings in the bios, correct? Also, the keyboard does no work when plugged into the ps port. No light comes on, no keys work ect. ANd yes, I have it in the right spot 🙂 (plus I tried both ports for girns and giggles). When that didnt work I figured maybethe keyboard was bad. So, I used my keyboard which is USB and it wouldnt work either, no lights cam one and no keys worked. My mouse is usb and the optical light powered on. I plugged the keyboard into the same spot the mouse had been and it still gets no power. I tried the new keyboard (Ps2 one) on my current desktop and it works fine. Does anyone have any clue as to what the delio is? I am assuming the mobo may be bad or maybe some crazy jumper setting? The board is an abit IS7 HT board and the processor is a p4 2.4 ghz HT chip. Please help, thanks 🙂
 
Yes the bios checksum is normal since it set the bios at the lowest cpu the bios can run. The only thing I can thing of is one of your jumper is in the wrong setting. The two jumper that comes to mind are: CMOS set on clear or normal? +5v power to mouse? maybe there one to the keyboard? I have that board big brother, IC7. It scream with those P4 2.4C. Ihave mine running at 3.4 Good luck.
 
Try a different ps/2 keyboard. You could also try swapping cmos batteries because many times they are dead even when the motherboard is new.
 
What about the case-to-motherboard power connectors? Any chance they are not installed correctly? Any chance the motherboard is shorting somewhere on the case? Have you tried removing it from the case and running it from the bench?
 
I recently had the same problem with a system and it turned out to be a short. I wasn't able to use the motherboard in the new case I bought. I had to put it in a different case.
