    I know you tested the RAM, however have you tried a different stick or booting on only one stick?

    Tried a CMOS reset yet?

The video adapter uses shared memory. It very well could be the cause of the second POST code.

Twice beep sound is coming. Booting is not happening for my p4p800 mx/s board


Hello !
If you check out ASUS support, you will find this troubleshooter for the motherboard not booting :
1. Please clear CMOS.
2. Please take out your memory cards and video card, try to clean their golden connectors with a rubber, then reseat them back.
3. Please take the CPU cooler out, add some thermal paste to the CPU surface, then reseat the cooler back and keep the cooler tightly installed.
4. Please keep the necessary components(CPU, one memory) onboard for a test.
Finally, we would recommend you to replace a BIOS battery to have a test.
Also, by looking over beep codes I have found for AMI BIOS these problems for the 2 short beeps :
1. Memory parity error (Description : A memory parity error has occured in the first 64 KB of RAM. The RAM IC is probably bad).
2. POST fail (Description : One of the hardware tests have failed).
If you have done those and it still doesn't boot, let me know I'll try to find other solutions.
All the best !

Memory upgarade


Yes, it will work. Remember that all memory will operate at the speed of the slowest memory though so unless you're completely replacing the memory it won't increase the speed of the memory.

A7V400-MX will not boot


In such cases its practical to change the SMPS with a working power supply of the same rating and then trying it out. If with the new power supply it works fine then cange your SMPS. Also make sure that all cables are snug tight and generally ree from dust. The same applies to your RAM too................sodeep

ASUS A7v400MX-SE VCORE Unstable


Maybe this tip is helpful:

Some bios test at the beginning the speed of the cpu-fan.
If the speed is to low, computer is switched off.
So pls replace your fan by a higher speed type.

Have you:

Made sure everything is connected properly?
Reseat (remove and put back in) the components (Memory, Video card, HDD, cables)?
Run with only the essentials (CPU, Motherboard, video, RAM)?

Will the PC even power up?
