I have a 2 year old laptop. The model is Sony Vaio SVE1511W1EB.
I never encountered any serious problems with it until now. However, last week I plugged a beamer into the laptop and did a Powerpoint presentation. After the presentation, my graphics card started acting weird. Mainly while using Skype, Firefox or at the start of a Youtube video, thin grey and glitchy lines started flashing randomly over the screen (horizontal).
They flash more and more until the screen freezes for a few seconds. Then the screen blacks out for about one second. After that, my graphics driver notifies me of a graphic driver crash. I can usually work for another half minute after that before it happens again.
After a few crashes it stops for a few hours. And then it happens again, completely out of the blue, while typing some text or scrolling through a page.
As if the problem wasn't bizarre enough yet these are some things I noticed:
- When I removed the graphics driver, the problem stopped, but flash player crashed at the very moment I opened a new website in Firefox.
- The problem doesn't occur in full screen games (even at the highest graphical fidelity)
- If I put my screen in the expansion mode (for use with 2 screens) the problem doesn't show at all.
- If I duplicate my screen to the other screen, the other screen (lower resolution) gets the same lines.
- If I change my display settings to show colors in 16 bit, the problem occurs less frequently
- If I change my display settings to show colors in 256 colors, the problem stops occurring.
I can temporarly fix the problem by constantly telling the laptop to work in expanded desktop mode (even when there's no screen attached), but I want a more definitive solution to the problem.
Here are some more details about my computer:
AMD Radeon HD 7550M/7650M Graphics [Display adapter]
PnP-beeldscherm [Monitor] (15,3"vis, januari 2010)
- Catalyst Control Center Version 126.96.36.199 ATI Technologies
- Catalyst Control Centre Version 188.8.131.52 ATI Technologies
I hope someone will be able and willing to help me.
Thanks in advance.
