I have an old computer with Pentium 4 and not much RAM. What is dead?

I turn on my computer, first time I get 3 beeps and then I take the plug out and put it back in I got way more. I just replaced the power supply with an Antec 650w earth watts power supply that could be what wasn't working. I then replaced the power supply with one I thought worked still doesn't turn on. Anything I can change?

You will need to find out the motherboard brand and model to find out the meaning of the beeps as they vary from one BIOS to another. For example, in this picture, the brand and model are printed under the CPU: Gigabyte GA-H55M. You will need to go to the manufacturer's web site and download the manual for the specific model of the motherboard. The beep codes are in the troubleshooting section of the manual.

For instance (this may or may not apply to you),

  • AMI, 3 short beeps: a base 64 KB RAM failure;
  • Dell computers, 3 beeps: motherboard failure;
  • IBM, 3 long beeps: keyboard controller error.

Hi. How can I tell if the motherboard on my ASUS S551L is dead?

Hi. How can I tell if the motherboard on my ASUS S551L is dead?. I have tried: Removed battery, hard drive and RAM. None of which I can see as being the problem. The power light comes on along with the caps lock light and number lock light but that's it. I think it was caused by: The fan was turning when I took the cover off

My PC simply went dead. I thne had the PSU tested. Its OK?

PC is still dead. Mobo is an ASUS M5A99FX Pro 2.0. It has 3 or four colored lights that come on during boot up to show progress. Green light is on. . . I do believe my Mobile is dead. Inexperienced and sometimes careless, I had plugged a sound card and a video card quite possibly into the wrong slots. Everything was functioning OK.. I could see the screen and hear audio.. . CPU: AMD FX8350 8-Core. Video: Cheap Old XFX GF4 MX440. Audio: Low End ASUS. I have tried: Tested PSU a Fry's. Its OK. I think it was caused by: MOBO Shorted out due to badly placed Audio and Video Cards in wrong slots?

Is my motherboard of my Dell PC dead?

Two nights ago, I accidentally put my headset point in the USB port of my PC, I heard a minor noise which sounded like static electricity, and it immediately went off. I tried rebooting it by taking out the battery and the charger and holding the power button for 30 seconds, it failed. Even tried holding it for a minute, it still didn't come on.
