Hi, my Mobility Radeon HD4670 has started recently to display weird artifacts (screen1, screen2, screen3, sorry for the low quality).
When this artifacts are visible Windows cannot boot in normal mode it displays BSOD with message "Attempt to reset the display driver and recover from timeout failed", only safe mode works. Sometimes this artifacts dissapear after some time.
Any idea what may cause this artifacts ?
