Asus p5kpl-cm boot problem

Test your PSU or replace it if your power supply units fan is not working your PSU is faulty

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up a computer hard drive

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your MOTHERBOARD TO YOUR HARD DRIVE make sure they have a secure connection and are not faulty or just replace them they could be faulty

make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electrical extensions or just replace them they could be faulty a computer needs its connections to continue its cycle and have an end so any faulty leads will end up with a computer error

even something as small as a faulty electrical extension or fan lead can cause you problems

computers need all of the data and electrical current to travel through every working device and to have an end to be able work properly

motherboard and a hard drive any leads between them will fail before your motherboard or your hard drive if its a flat ribbon 40 pin type IDE replace it this will be the first to fail

check all electrical power input and extensions make sure they are securely seated even the cd/dvd floppy drives need to have current go through make sure these drives are working

also check the Cmos battery and computer RAM modules make sure they are securely seated with no dust built up or in the sockets on some motherboards cmos batteries are soldered in

check you CPU make sure its securely seated and has thermal grease

hope this helps you

Try updating BIOS and Intel Chipset

your bios driver is likely to be faulty.
so download a valid driver then update your bios again.
if it doesn't work, intercept all of cables of your PC case and even power cable of your monitor.
evolve battery of bios then wait for 15 minutes then connect all of cables and try turning on your pc:
1- with battrey of bios
2- without battery of bios
it should work.

Sounds like your on board graphics has went bad. since you have a PCI-e expansion slot your can buy a PCI-e graphics card to fix the problem.

The problem is with your memory installed try inserting other RAM on your computer or if you have two memory installed try removing the other one and see if it works.

well where u attach the front panel leads there is a jumper behind that with theree pins it is in the 1 2 pins change it to 2 3 and try power on after that set it back to 1 2 and then restart your BIOS settings will be refreashed. set to builtin vga again.

Disconnect all devices from the power supply EXCEPT the motherboard
Remove any extra cards including video etc.(plug monitor into the onboard)

If you hear any beeps these can indictate where the fault is.
either of these sites below will help you further with that

Beep codes Pc

More beep codes

Power up the pc and see if the fans are working.
If not then double check the power connections to the board.

If you still have no fans it is time to suspect the power supply as the probable cause.

If the fans worked then you should have gotten a display which told you there was an error and offering you a chance to go into the BIOS. ignore it and shut down the PC.

Now connect one drive only and boot again.

Repeat that until you identify the component that is giving you a problem.

Once you find the problem then remove or disconnect and carry on with the rest to see if another component might also cause a problem

If there is only one problem device then you may want to investigate that device further, Unless you don't mind replacing it

make sure you didn't forget to plug in the cpu-power-cord (4 pins, squarish)
