I'm sorry if I've missed a solution to this problem - I have been looking for a few days, but I'm new here. I have a potentially serious graphics card problem that I could use some advice on. Sorry for the epic length.
I used to have a dual boot Windows XP/Edgy laptop, but after buying a new laptop I abandoned Ubuntu for awhile. (I say this so that you can know that I was never a pro, and I'm a bit out of date, but I'm not completely unfamiliar with this stuff.) This Christmas I have a bit of free time, so I've been drifting back. I started by installing Wubi and Hardy Heron on my Dell Latitude D630, which runs Vista.
My graphics card is an Nvidia Quadro NVS 135M. I installed the Nvidia drivers available in driver manager. Specifically, I installed 177, but I found that it pulsed my fan strangely, so I switched to... 173? (These numbers are out of my head, hope they're right.) That one seemed to run fine.
That evening, I was booted into Linux, watching a DVD on my external monitor while my laptop charged - so probably running a bit hot - when the computer locked up. The screen froze, the mouse froze, even the indicator lights froze. When the computer booted up, I had two grainy, low-res displays on my laptop screen, one stacked on top of the other.
Vista ran startup repair a couple times, then made quite a few changes through chkdsk (unfortunately, I didn't take notes) and finally booted with normal display. Stupidly, I took this to be a problem with Ubuntu, and uninstalled Wubi. Even once my display looked normal, I wasn't able to play DVDs in Vista - nothing happened when I told VLC to open disc.
The next morning, everything, including DVD playback, was fine. But that night, while I was again watching a DVD and charging my laptop, this time in Vista, exactly the same thing happened.
So, I figure, this is a hardware problem. I now know there are big problems with my Nvidia card, so I figure it's failing and call Dell tech support. They encouraged me to update my driver and BIOS, and then try to provoke the same error. If it still crashes, they say they'll send a tech to replace my graphics card.
BUT now everything is running just fine - I ran a DVD for two hours, four times as long as last time, while my laptop charged, and it didn't even stutter. So here are the possibilities, as I see them.
1. The card is failing, but its failure has been slightly delayed by the new BIOS and driver, which run the fan more. It is entirely coincidental that it started to fail right after I installed Ubuntu. I should replace the card and reinstall Hardy Heron with the 173 driver.
2. The card is failing because, for a day or so, I ran an outdated Nvidia driver that didn't run the fan enough. Because my card has high failure rates, this slightly higher-than-normal temperature wrecked it. If this is the case, I need a new card, but I also need to be careful in my configuration of Ubuntu. If this is the case, I need to figure out a way to run the 177 driver without going insane - maybe I need a utility to take over and slow down the fan, but not so much that my computer overheats.
3. My outdated BIOS (it was version 3, now it's version 15) was the problem. This is why I had the same error in both operating systems. My card is still delicate, but not permanently damaged, and it should run fine under the new BIOS on both systems, though my battery life has taken a hit.
I welcome any (1) guesses as to which of the three scenarios I'm in, (2) alternative scenarios, (3) suggestions on how to proceed.
