graphics card- purple lines HELP

green1 · 10-30-2005, 03:21 PM

hi,

Recently started having problems with my ATI Radion 9700 pro, i have the latest drivers installed etc. However, my pc sometimes starts fine and remains this way for 5 minutes, and then all of a sudden Purple lines begin to form accross my screen and it even sometimes becomes impossible to see the screen due to these purple lines. Then, maybe after a further 5 minutes or so the lines will disappear. I did recently however, change the fan on my graphics card, so the first problem i thought of was that the fan was not fitted correctly, so i have taken the fan out and put it back in again in various ways, as well as making sure the fan actually works when the computer switches on - and everything checks out fine. I cant put my finger on why all of a sudden this problem has occured.

I have managed to identify my graphics card as the problem by replaceing with with a friends, and having no problems at all

My pc is used mainly for gaming, so i also thought that stress could be an issue, but since the card has been working correctly for over a year, i dont see how this can all of a sudden be causing problems.

Any feedback/solutions to this is greatly aprechiated.

Asus P4C800 Deluxe MB
Intel P4 2.4GHZ @ 800Mhz fsb
768MB DDR3200 RAM

let me know if theres anything else you need..

I've just put an external fan to the side of my GPU and it seems to be helping, but i dont understand how the fan on the card its self isnt sufficient enough to cool the card, its pretty much the same fan as was on the card before i replaced it (the fan seems to be working perfectly)

EDIT: even though the fan helped maybe a little bit, it has far from solved the problem.

Important Question: Did you use Thermal Compound on the graphics chip *before* mounting the fan?

I was thinking it was a heating issue as well, because purple lines seems like Artifacts to me.. i dont think you placed the fan on correctly or like the person said above me did you put and thermal paste on the chip?

oh... purple lines...
mine was brown lines -- appeared severely on normal windows desktop, IE, Words, Photoshop...etc applications. first i thought it was my ATI 9600, but later discovered that it was my Samsung 795 monitor having problem.

good luck! :thumbup:
