Default Something New (for me at least)

OK,

-HP Laptop
-Windows XP 32bit
-2 gigs of RAM
-Intel Dual Core
-250 gig hard drive

A customer brought this in and told me it got hit during the storm and proceeded to reboot itself. After the reboot it would blue screen right after logging in. When I fired it up, the blue screen was so fuzzy I could barely read it. Hooked it up to an external monitor, same thing. I was able to make out a page fault error. Fired it up in safe mode with no problem and saw that the ntoskrnl.exe was the root of the crash. I replaced the file and all is good.

My question is with this distorted blue screen. Just to make sure, I stress tested everything and there were no errors. I also uninstalled/reinstalled the video card driver to play it safe. Is it possible the corrupted ntoskrnl.exe file was messing with the video driver causing the distortion or could there be something else? A Google search provided no help

ntoskrnl.exe loads system drivers, which include video drivers. If the video driver didn't load, it was probably running in 640x480 resolution.

Right, but it wasn't in 640x480 resolution. It was in standard resolution but all fuzzy.

Perhaps it was the refresh rate. I seem to recall a similar problem (fuzzy screen) with bad drivers that defaulted to a bad refresh rate. But it's too early to for "remembering"

Most likely when the kernel crashed, it also corrupted the video card driver (in memory). Since you replaced ntoskrnl.exe and the video card drivers you should be fine.

If you wan't to make sure - you can crash the system on purpose using NotMyFault (download link here: http://www.technibble.com/forums/sho...3706#post53706

Very nice; reminds me of NTest, which I used for years when repairing monitors.
