BIOS is not running on power on

Posted on 2007-11-28
Last Modified: 2013-11-09

I've recently upgraded my P5LD2 SE/C motherboard to a P5LD2 Deluxe motherboard.  All of the PCI cards, memory, processor (Core 2 Duo, which Asus say is supprted), graphics card (PCI-E 16x) and hard drives are the same.

The problem I have, is that upon switching on there doesn't appear to be a BIOS, as all i get is a blank screen.  No system beeps or anything.  I've checked that the CLRTC jumper is correctly installed.

Anything else I should try before i send the board back as faulty?

Make sure you have connected both connections of the powersupply to the board (also the small square 4 pin one).

and test with all devices disconnected, leave only mobo + cpu +1 ram stick, video card, PS
if still nothing swap the connected devices
check also if your cpu is correctly installed

I will try your solution when I get home tonight.  My last motherboard didn't have the 4 pin extension plugged in, so I didn't plug it for the new board either.  How do you know whether to plug the 4 pin bit in or not?

Check which ports are open to the outside world. Helps make sure that your firewall rules are working as intended.

Those boards that have such a plug, need it, those that have that plug missing, don't need it.

I've found out that only version 2 of this board will run core 2 duo.  Mine is V1.02.  

Why my manual says it does support dual core processors I do not know!

Thanks for your help anyway
