Comp Building problems

[Istonian]

I am building a computer for my uncle and I came across a problem. I installed everything right and when I went to turn it on it beeped a long one and two short beeps. I have tried different RAM, different hard drive, different power supply but it still did not work. If it is the video card I can not do anything about it. I do not have another video card and my mobo does not have built in video. Help would be appreciated.

What BIOS company is it? Just check their website for the beepcodes, or have a look on the mobo manufacturers website for the beep codes. That will tell you whats up then you can go from there

yes, do what Raffaz said. and to quicly elimiate the video card as the problem, take it out and boot it up. if it does not beep, then you know what the problem was.

It is a phoenix BIOS so im checking on the site.

so wat if it beeps, can u run the comp? u didnt mention anything about not being able to run it.

 

[Istonian]

Yes it runs fine it just beeps and doesn't display anything. it sounds like a normal computer starting up. The processor runs and every thing, power supply works. Everything but the display.

this happened to me on my asus because i was using OCZ. when i switched to corsair it worked great..idk if that helped

 

[Raffaz]

so wat if it beeps, can u run the comp? u didnt mention anything about not being able to run it.

If it was running fine it would beep once to say it POSTed correctly, his never done that so theres a problem

 

[Istonian]

That is what I meant is it will turn on but wont post anything.

This guide i made helps most people with this problem



THE BAREBONES HARDWARE FOR VIDEO BY LAMBOFGOD

the only required parts you need for video are.

1.Motherboard
2.Powersupply
3.CPU
4.RAM
5.Videocard /unless you have onboard video

And make sure you have a known good working monitor and power cables for both the PC and monitor,
and make sure the monitor is powered on.

and before when even get down to it , Make sure you have a large enough power supply.
Dont even waste your time doing this if you are trying to boot a system with 2 X1950XTXs in crossfire, and 6 Hardrives with a 300 Watt power supply.


Ok Lets Start

1. REMOVE the motherboard, place it on a Plastic surafce/ such as a rubber mat, or a large square of packing material.

2. Start putting the ram, cpu & heatsink/fan, videocard (some videocards Need additional power make sure you are plugging power into these places as well). ONE thing at a time, double check and make sure everything is in place properly and plugged in I.E. CPU fan.

3. Plug the power supply into the board (some boards require additional power, make sure you are plugging the power into these places as well),

4. Take your case and move it by the board and plug the powerswitch onto the CORRECT pins on the motherboard.(consult your motherboards manual if you dont know where these are)

5. Also try hooking up the small speaker in your pc to the CORRECT pins on the mobo to get a diagnostic beep code. (consult your motherboards manual if you dont know where these are)

6. Hook up the monitor to the back of the videocard, carefully, its not screwed down so it can pop out easily. (if your using onboard video this step does not pertain to you)
If you have onboard video just plug it into the VGA port of the back of the motherboard.

7. Press the power button.

Did you hear any Beeps? any video?

If you still dont have video try this only if you have both onboard video and a Slot based videocard I.E. PCI-E/AGP/PCI pull the Slot based video card and try the onboard)

still none?

If you still dont have any video, Try replacing the easiest compents first, such as Ram, then Videocard, then PSU, then CPU, then Motherboard. Just ONE at a time and try booting and listening for beeps after each one.

Make sure you have known good working Componets your replacing them with as well, and make sure they are compatible.

That should narrow down what componet is causing trouble.

Good Luck, LambofGod
