Help ;(

My system:

Motherboard: Nforce A939
CPU: AMD 3200XP
RAM: 2gig DDR
Power Supply: 420 watts ATX 12v
Graphics Card: Nvidia 6600GT
Hard Drive 150gig (IDE)
OS : XP

Problem:
My computer appears to power up and everything spins but nothing appears on the screen and i get 1 long beep 2 short

I have tried this so far:
Purchased new MOBO (GA-EPS31
Purchased new RAM 2gig DDR2 800 hz Kingston
Purchased new RAM 2 1gig DDR Corsair
Purchased new CPU Intel Dual Core E7400 2.8 ghz
Purchased new Video Card Nvidia 9800GT

I have also tried swapping screens from flat screen to CRT,tried a different hard drive and tried a different case. I have also tried swapping RAM slots of course.

Results: no change in the problem, computer powers up, nothing comes up on the screen and i get the long been 2 short beeps

RANDOM INFO:
I have no extra power cables to my video card, do i require them and what are they / where are they. There is a 6pin slot on it. My other video card didnt need have / need any though i believe.
I have the giant / tiny cable together onthe MBOARD and the CPU power cable connected.

I'll probably have to withdraw from my study if i cant fix this, been 2 weeks trying so far.

I'm some what confused as to what system you actually have together. As it seems you completely bought all new parts. However , one long beep followed by 2 or 3 short beeps in computer language is typically a video problem.

The very first machine you have listed isn't posting , which means it could literally be any component , usually a bench test will reveal which component is causeing the problem. Normally it's a card or drive.

The seceond machine you have listed isn't posting because the video card NEEDS the extra 6 pin pci-e power connector connected. The card also require a quality 600w or higher power supply with 26amps on the 12v rail. 420w isn't enough.

Your psu is too weak to handle the pc.

Antec
Corsair
of atleast 550 to 600 watts

Cheers, i'll try a new PSU today.

Hopefully they come with a new connector.

Go with a corsair or Antec power supply unit

There's actually no antec units we recommend anymore. Stick with corsair , thermaltakes toughpower , coolermaster , silverstone , pc power and cooling , ect..
