Big problem with 8k5a2+ new problem

[Raedon]

For some reason the video output (both monitors) seems to now have these virtical lines that are just bearly noticable moving up the monitor. I thought it was the duel monitor but I disconnected the monitor on the DVI and i still have the problems with both my monitors.. it's getting worse, what could be causing it? it happens from 133fsb to whatever.. I re set the board and i still have the problem.. this is a fairly new GF4ti4200 and it's the first time i've seen these problems on any computer.

Could the Epox board have killed my gf4 card? If so they will replace it correct?

[Raedon]

no one have this problem before? where there seem to be like a light artifact in the image like some water was flowing up the monitor image?

No Manufacture will replace parts other than their own, at least I've never heard of one doing so. Very unlikely that your motherboard would kill you Video card. Even when my PSU blew and melted my motherboard at the main connection from the PSU my GF2 came through it fine and still works quite well.

While it's possible that your card is at fault, I doubt the mobo could have damaged the vid card.

Sounds like bad drivers. Have you tried different drivers yet?
Are you overclocking the video card or CPU?
Probably nothing, but do you have anything near by that could be sending EM waves... like unshielded speakers?

edit: this thread might get better responses in the video topic.

that's fine.. I could RMA the gf4 but i just confermed some things.. my problem is now this.. the gf4 works fine in my sever, no problems.. And I put an old TNT2 on the Epox and no problems.. I put the epox and the Chaintech gf4 together and I have problems.

The problem looks like.. Like if you overlayed a field of water over the monitor(s) and tiny tiny waves were flowing up the water distorting the image. I didn't notice it before because It's almost not noticeable at 1024x768 but as the resolution gets higher it gets worse. I changed to a 1200x1024 desktop and started seeing the problem. No I can see it even at 800x600 because I know what to look for.

Changing the refresh rate doesn't help. 60-100 refresh and problem is the same.

[Raedon]

can i get some Epox support in these forums?

[Ibn]

Did you try hitting the 'Degauss' button, or selection on your monitors? Should be there somewhere... You may have a wee bit of magnetic field effect occuring. If thats not it, try changing your refresh rates and see if the effect goes away.

good luck

please read my previous posts before trying to help, although it is appresiated.

I have changed refresh rates and degaused.. switching to an old agp card, i don't get the same problems with the exact same setup. Nor does the gf4 on a different computer exsibit the same issues.

From what you describe it sounds like you have a lot of RF noise in the cables. If you only use one monitor do you still have the problem?

I had what sounds like a very similar problem once and I solved it with just going with thicker, more heavily shielded video cables.

I should read more carefully :-) So you already tried one monitor only. Um I guess the question is does it look like its part of the signal or is it noise from some other source? Maybe trying to see if you still have the problem at a low resolution might shed some light.

I swear I can't figure out what it is.. I tried everything last night. New drivers for everything. Moving the computer to a different room, switching cards from computer to computer..

I can't get this Chaintech gf4 to work right on this 8k5a2+ I've even flashed every board bios to see if that helped.. ARHHH!!!!

[Uncle Bob]

Try setting the AGP to 2x in the BIOS and disable fast write and the 2 other options in the AGP part of the BIOS and see if that changes anything. Do them one at a time and perhaps you will be able to ferret out the culprit. My thought is perhaps it's in the BIOS. What version are you using, anyway? Try 2929 BIOS as this is an agressive one for memory timings.

Just a shot in the dark! I know what it's like to wring your hands and mutter at the PC!

Well i have the very same problem with mine I have Radeon 9700 Pro and I rma'd the video card to Ati and yet I still have this issue! I thought it was my Video card But I can see that it is not it now!

[Frank_G]

Well one more thing from the old days of Radio and TV Repair it looks like it is a capacitor leaking voltage but then it doesn't do it all the time on my machine either!!

Try this... take your entire computer and move it elsewhere in your home. That is, to another power plug. I had the same problem as you are describing and it turned out to be a power problem.

Also, try a different power supply. Something with more wattage, since you say that this problem dissapears when you change AGP cards from one that draws more power to one that draws much less.

[Raedon]

done the moving of the computer as it says above..

I have a 430w PSU in the problem system... the gf4 runs fine in a server with a generic 300w..

I'm out of things to do now but RMA..

[Doomer48]

Do you have a fan next to the computer? Or are your video cables laying across a power cord? It sounds like rf interference. It could be from anything plugged into the same power outlet or its electro magnetic interference. Do you have a case cover plexiglass window mod, that would let interfernce in as well as out. Try and isolate everything else from the pc and monitors.
