New Computer Build Help

[Ry3Lamp]

Hello all;

I just pieced together a new computer with the following main compontents:

evga-GeForce 7800GT graphics board
MSI K8N Diamond Plus motherboard
AMD Athlon X2 4400
2 gig OZC Memory

The problem I am having is there are horzontonal lines (not one, but many) across the whole monitor. It is very distorted and hard to read or see anything in any detail. When I connect to the internet and scroll the mouse, the whole screen gets so distorted, nothing is legible.

I know the monitor is fine. I have used it on another computer with no problems.

Have any of you run into this problem before and know a fix for it?

Thanks for any help.

Ryan

Could be bad dvi or vga cable? Might try isolating power cords away from the display cable.

If that fails check your temps. How many fans do you have and is your video card fan functioning? Maybe you forgot to hook up the power cord to the video card? Do you have enough power in your rig? (PSU, power supply)

Yes, I have enough power, 500w PSU. ALl my fan cables are plugged in too.

If it matters, the display was distorted when I was installing windows, at first, then it cleared up, then it distorted.

This is very strange to me.

What is the name of the manufacturer of the PSU? A no name PSU brand would get its *** kicked by a antec true power wiht lower wattage.

I have an Antec Neo HE 500 PSU.

I fell that I have pretty high quality components, so the quality shouldn't be an issue.

On a side note, the distortion is also present when I am in the BIOS.

Thanks.

I called eVGA product support and they said I need a PSU that outputs 18A on the 12v rail. Has anyone else heard of this?

According to the card packaging, I meet all the min. requirements for this card. I would hate to have to go and drop another 100 bones on another PSU.
