Been lurking here for awhile and finally decided this was the place to ask for help. Really like the HTG website!
Have an hp DV6000 series laptop running (well, not now ;)) Vista w/the dreaded nVidia GPU overheat issue (I think). I can get Vista to start, but after only a few minutes, the system locks up and the screen displays zig-zag or diagonal lines of various alternating colors. Then, only a hard re-start will get it going again. Have done a lot of research on this issue and seen many videos of how to "Re-flow" the GPU chip to the motherboard.
Since the Vista problem started, I decided to use my trusty Ubuntu Live CD to troubleshoot the system. Ubuntu runs this laptop flawlessly and I never have any graphics or freeze-up issues. Been using it this way for about a month now.
So, here are my questions:
1) If it's a hardware problem, why does the Ubuntu Live CD run the system without any problems?
2) Do any of you know if Ubuntu doesn't actually use the on-board nVidia GPU, but some other form of video emulator?
3) If #2 answer is Ubuntu does NOT use the on-board graphics, then can I make Vista run without using the on-board graphics? (This may be a question for the Vista forum.)
Thanks in advance for any help/advice you can provide.
