Screen is blank and computer won't boot

Start by defining what the beeps mean.

Here is a link to a Tech Republic download list of BIOS beep codes.

Continuous beeping usually means that the monitor is bad or unplugged, or that the video card has failed, or is partially out of it's socket.

So, try a different monitor, then try re-seating the video card in it's slot.

I tried swapping out my video card with another system and I have the same problem. I also checked out the beep codes for my BIOS (Phoenix) but it doesn't have the code my system is giving. It is a beep that lasts a second with a second of silence, and it repeats over and over. I also reseated all my cards and cables and it had no effect.

Do you get the POST messages coming up at all? Does it hang halfway through, or do you just get a blank screen?

It's worth reseating all your components, (video, RAM, sound, power plugs, CPU etc) and cleaning any dust out of the CPU fan and the box in general.

I've seen PC's beeping when the power supply is failing, and not supplying enough power.....

I've also seen them hang up at boot for no apparent reason, and if you disconnect the mains power, and reconnect after 30 sec it's OK....

Long beeps over and over again usually mean memory problems. The memory may have gone bad or come unseated. Try to remove the ram and reinsert it. You can also test to see if that is the problem by removing the ram and powering up, if you get thesame result, the memory is the culprit.

Sure sounds like a memory problem to me too. If reseating the ram and the CPU don't fix it try removing 1 stick of ram and try to boot. If that doesn't fix it remove the next stick and replace the first stick. Keep this up until all the ram has been pulled with the previous stick put in it's place. You can also try putting the ram into a known good system. If you have another system you can swap out the CPU too.

I suggest clearing CMOS in between swapping each part ...the MOS can get confused or hold the old setting.

I reseated my RAM and still no luck. Also, the monitor isn't getting a signal. Wouldn't the BIOS flash up on the monitor even if the RAM is bad? You were right about the the signal not changing though. It still has the same beep even without theRAM installed.

The beeps are a post code when screen is black it is usually memory or the video card. Your MB manufacture should be able to provide the exact audible error code (just an example) 3 beeps is a video fault. Try reseating memory and video cards. Make sure you unplug the power cord before attempting to remove any hardware.

check your bios settings.. set them to default.. when my board is set to AGP turbo mode, it beeps like that...
