I have a Gateway MX6920 running WinXP MCE 2005 with SP2. that has been crashing. I first had this type of random reboot on 11/24/07, and have been having them somewhat regularly since. As far as I can remember, it's always been BCCode 77. The BSoD would only flash for a second before the computer reboots, and when Windows would load up again, there would be a dialog: "Windows has recovered from a serious error" with links to the minidump files. After some research, I came across the "Before posting your minidumps, please read this" guide on this forum. I ran a disk check (today's check said the volume was clean), ensured the RAM contacts were clean, ran Memtest86+ for 13 passes or so with no errors, ran Everest today (hardware report attached, not sure how to interpret the information on power supply or temperature), and have cleared my pagefile twice since the errors started with an accompanying defrag to no avail. The only thing I noticed was that the Everest report includes the following in its Overclock section: Code: CPU FSB 266.06 MHz (original: 133 MHz, overclock: 100%) I don't remember ever going into the BIOS to set this up, and I'm not sure whether that can be the culprit. Any help will be greatly appreciated. Thanks.
