Hello, I have the Asus p5q-e And just had my power supply burn out on me. I went and got another Power supply, Went up from 400 watt to 550 watt. Now there's power, but im getting a POST beep code. I cant seem to find my motherboard book to know which kind of bios, i need to look up to figure out what the beep code means. Though since i ended up here. Im getting a beep code of one long beep and three short beeps after. My initial guess is something happened to my ram. Ive reseated and moved the original sticks around within the different slots, Same beep code. Before i go out and buy new ram. Id like to know if its something else i should be looking into to fix my problem or what?"
To eliminate the possibility of a bad installation where something is shorting and shutting down the PSU, you will need to pull the motherboard out of the case and reassemble the components on an insulated surface. (cardboard box will work) This is called "breadboarding" - from the 1920's homebrew radio days. I always breadboard a new or recycled build, it lets me test components before I go through the trouble of installing them in a case.
Pull everything out of the case and reassemble the PSU, Motherboard and CPU/HSF.
You should hear a series of long single beeps indicating memory problems.
Silence here indicates, in probable order:
a bad PSU
a bad CPU
a bad motherboard
a bad installation where something is shorting and shutting down the PSU.
First step if you get silence is to swap out the PSU for the same setup as above and test again.
- At this point you have ruled out the PSU as the culprit.
If you still get silence, then go back to the original PSU and swap out the CPU.
- At this point you have ruled out the CPU as the culprit
If you still get silence, go back to the original CPU and swap out the motherboard.
- At this point you will have ruled out the motherboard as the culprit
Once you get the long beeps during any of the above situations, add a stick of RAM and Boot.
The beep pattern should change to one long and two or three short beeps.
Silence indicates that the RAM is shorting out the PSU.
Long single beeps indicate that the BIOS does not recognize the presence of the RAM.
If you get the one long and two or three short beeps, test the rest of the RAM. If good, install the video card and any needed power cables and plug in the monitor.
If the video card is good, the system should successfully POST (one short beep, usually) and you will see the boot screen and messages.
