Yes, now I temporary live in Cambodia. It's really not far from Vietnam. Neighbors...
Today evening I'll check Win 7 according to your suggestions and inform you about results this week.
02.07.2010: I checked the C: disk- no results. SFC/ Scannow I didn't try, because both the Windows installation disk and Windows activation code I leave in Belarus. Here I have only laptop with installed Windows. So I'm worry that after SFC I'll need to Activate Windows again.
As I understood I don't have easy options for repairing without Windows Installation disk. So I will try to update video driver
and if the problem still ocurr again- I'll keep my laptop as is. And will return to repairing after come back to Belarus. Correct?
Thanks for your care,
