I have a Dell Studio XPS 1645 laptop.
(Basic configuration: Intel (first generation) Core i7-QM quad core processor @1.6 GHZ, turbo upto 2.8 GHZ, 4 GB RAM, ATI Mobility Radeon 4670 w/ 1GB DDR3)
One fine day, doing nothing particular, my screen went all crazy, with all sorts of lines on it, gave me a BSOD that was barely visible, and crashed. And crashed again and again for the next two dozen times on boot. Even the splash screen had those lines. I got some pictures to illustrate, have a look.
I later viewed the contents of the BSOD, didn't convey anything in particular.

Subsequent attempts to boot all result in a BSOD, as shown above. I did, however manage to boot in safe mode. Although, it looked like this.
Also, when I disabled (and also uninstalled) my ATI graphics card drivers, I could boot normally, but with the crazy lines, so basically, the graphics card is what was causing the BSOD, although the issue still persisted, indicating the cause was something different, possibly the on board graphics processor.
Also, I really don't think it's a software issue, since even at the splash screen, the problem persisted.
The second image above, the appears when the screen ought to have been blank.
And another peculiar fact. After running the diagnostics tool, with the weird lines, on the next boot up, at least from sometime the problem seems to have disappeared. Although, the diagnostics screen looks like this:
This problem appeared the first time about a week ago. I did some massive graphics drivers (that time only the ATI one) uninstalling/reinstalling etc. By the time I did this, and ran some integrity check, my computer just powered off during the reboot, but that was because it was really really hot. I let it cool down, and on the next boot it booted just fine, I reinstalled all the drivers, and it ran fine for about a week. And then today it happened again. As I said, after the diagnostics, it runs fine for a while, as it is now, when I'm typing this in. Could anybody tell what the problem might be, and what could be done? Any help would be greatly appreciated.
P.S. The on-board graphics cannot be disabled, at least not from the BIOS. No such options exist.
