Hi,
After trying to fix the problem I have on my own, I finally decided to post a message on this forum. Hopefully somebody will be able to help me.
I have an Amilo M1437G notebook with an ATI radeon mobility x700 video card. I've been using it without problems for 10 months until one day when the display started showing thin vertical lines. They were shown from the moment the notebook was started up. In Windows, the lines were more colorful and usually the notebook hanged or restarted after a few seconds.
However, it worked in Safe Mode (no hangs), although the lines were still there.
I took it to service and they replaced the video card. (although it took 2 weeks)
After a few months, the problem is back. The guarantee is over so I had to solve it myself this time.
I opened the notebook and found that the heatpads between the video card and the radiator were laid over the coils too (the coils are taller) so I think the memory chips and the GPU have not been in full contact with the radiator. I put them properly, added some heat transmission paste. Also, I'm using NHC with the ACPI option "Lufter Off-line" unchecked, so the cooler works more.
I installed the Omega drivers, I read that they are better than the default ATI drivers.
The problem shows more rarely now (every one or two hours), with the system hanging with a black screen or rebooting or showing a black screen and recovering with a different error each time.
Any other hints of what else should I try?
If the only solution is to buy a new card, where could I buy it online? The last time I went to service I had to wait two weeks for the card. Also, if there is a video card with less performance but more robust, I would like to have that one. I am a programmer, I don't need fast 3D nor high frequencies.
Thank you,
