Hi I was wondering if somebody could help me. I'm building a computer for the first time I have everything installed and connected in my case. I'm using

motherboard: Asus P5QL PRO
Processor: Intel Dual-Core 45nm, 6mb
RAM: A-data DDR2
Power supply: 500w
Video card: Asus 9500Gt TOP


When I start the computer the light turns on the front and on the motherboard. I also get power to the processors fan and the CD/DVD drivers work as well. I don't hear any beeps at all and no signal to the monitor. There is a cable that is connect on the video card that is connect to the OUT S/PDIF plug on the motherboard. Could I have fried the motherboard or Processor or is there something I can try. The manual with the motherboard said something about Jumpers, but I didn't think that I had to do anything with that to make it work. If anybody can help with this it would be great.

Short summary and focused diagnostics based on 's update and 's suggestions.

The fact that switching to a DVI cable produced a picture indicates the first “no signal” was likely a display/cable/output mismatch rather than a permanently fried board. The later freeze after changing keyboard/mouse is a separate symptom and needs isolation. Run the tests below in order; each step narrows the cause and keeps you from replacing parts unnecessarily.

  1. Power-down, unplug, and ground yourself. Move the board to a non-conductive surface and run a minimal bench build: CPU + cooler, one RAM stick (use the slot nearest the CPU), GPU only if there is no onboard video, PSU 24-pin and CPU 4/8-pin connected, speaker on the front-panel header, monitor attached. No drives, no USB devices, no front-panel LEDs. Power on and watch for POST/beeps or any display.

  2. If you get POST/display: add parts back one at a time (keyboard, one USB device, drive). If the problem returns when a particular device is connected, that device or its port/header is the culprit.

  3. If no POST/display in the minimal setup: confirm the CPU power connector is seated, try the other RAM stick or another slot, and clear CMOS (jumper or remove battery for a minute). If still dead, try a known-good PSU or test the board with a different GPU. Inspect the socket/board for bent pins, misplaced standoffs, or solder shorts.

  4. Keyboard-freezes that happen only after swapping input devices often point to USB/BIOS interactions or a short from front-panel wiring. Try a PS/2 keyboard (or a different USB port), reseat front-panel connectors, and enable/disable USB legacy support once you can get into BIOS.

If bench tests fail after these steps, document POST/beep behavior and consider RMA or having a local shop test with spare parts.

The only reason I can think of to plug a cable from motherboard to graphics card is for audio that comes through to your graphics card's HDMI out plug. I'd disconnect this cable.

Do you have 2 sticks of RAM? If so, try just using 1 in the slot closest to the CPU. If this doesn't work try the other stick. Try it in the slot furthest from the CPU also.

Check the Asus website to be sure that motherboard supports the latest 45nm quads without a BIOS update. If it needs a BIOS update first, you'll need a compatible CPU to do the update, which is a PITA.

Let us know how you get on.

OK well to update this issue. I have remove the cable for the video card, but this didn't seem to work. I switched the cable that came with my monitor with a DVI cable. This did work for some weird reason my monitor came on. The Bios got installed and windows as well and it was working, until I removed an older keyboard/mouse I was using, with newer ones. It seems to freeze windows when I plugged something into the mobo. I then started getting the same issue as before. No power to the monitor or anything else. I'm thinking that the mobo might have an issue. Any thoughts.
