27-06-2008, 07:07 PM
just installed this mobo Asus p5kpl-cm, everything plugged in correctly turned on no post, no bios and tried XP disk that I know works nothing screeen stays blank. Any ideas?

Is the graphics card an integrated card or a dedicated (PCIe or AGP) one? It may be a faulty card.

Lights? Fans? Beeps?
Board shorting out against mounting spacers?, (too many fitted?, easy to do ;)).
Cards pushed in/lined up with slots? (video and ram, have had boards not line up correctly with case backplane/slots and cards pulling out).
Take board out of case and connect everything, if it still doesnt boot, try disconnecting or substituting until it does, if still not, maybe is DOA.

Its intergrated even tried my old working PCie card and still nothing. I removed the RAM and got no beeps either

How much ram is installed?? / how many ram slots are filled?

According to the ASUS FAQ for this mobo

For some reasons, my system just refuses to boot when loading four DIMMs onto this motherboard.

System works like a champ when installing these DIMMs onto the motherboard separately under one or two dimm configuration.
Is this normal?

Yes, this is normal.

Due to Intel G31 chipset limitation, this motherboard can only support up to four banks of DIMM in total.

Installing memory over this limitation will result in system fail to boot completely.

Please use all single sided DIMMs if wish to occupy all four DIMM slots on this motherboard.

This applies to your mobo, the P5KPL/C-1600/VM

Yes its a 24 pin and the 4 pin both plugged in correctly just off to the garage for another poweer supply

27-06-2008, 07:45 PM
this mobo only has 2 slots and saccording to the manual should run double or single sided RAM

Hmm youre right

Whats the speed / specs of the CPU??

The BIOS on the system may not support it

If the CPU is

Core 2 Duo E7200 (2.53GHz,1066FSB,L2:3MB,65W,rev.M0)
Core 2 Duo E7300 (2.66GHz,1066FSB,L2:3MB
Core 2 Duo E8300 (2.83GHz,1333FSB,L2:6MB,65W,rev.C0)
Core 2 Extreme QX9770 (3.2GHz,1600FSB,L2:2X6MB,rev.C1,4 cores)

You need BIOS update 0509

Or this

Core 2 Quad Q9450 (2.66GHz,1333FSB,L2:12MB,rev.C1,4 cores) 0512 beta

Other CPU's should work with the BIOS that's on it (0305 the first BIOS release) according to the ASUS site

I would go here and see if its listed (http://support.asus.com/cpusupport/cpusupport.aspx?SLanguage=en-us&model=P5KPL-CM)

There's a lot of 3 ghz CPU's there

27-06-2008, 08:18 PM
%@#%%^*& mines the P4 519 and it's not listed %%$^@# again guess I'm going shopping again.

You could try getting the BIOS update (http://support.asus.com/download/download.aspx?SLanguage=en-us&model=P5KPL-CM)

Take the system into the shop see if they can put a lower spec CPU in it then flash the BIOS.

Then put yours back in, and see if it works

Then you'll see whether the CPU is still working or whether the BIOS update will fix it with the CPU you've got
