Here's an interesting scenario: Since it got warm where I live, I've been having heat-related issues with my computer. Ok, fine. So I take it all apart, vacuum it out, put it all back together. Except... Now Windows XP won't boot! It keeps giving me a Blue screen with the error message that's in the subject line and says that Windows Startup has been halted so that the computer wouldn't be damaged. And it says to remove any new hardware from my computer and to disable all caching/shadowing in the BIOS. Ok, so I do that. My computer is nothing but a motherboard, processor, some RAM, a hard drive, and a vid card at this point. And the darn thing STILL won't boot. I've tried repairing it with the Windows XP CD, and it kicks me back to that screen. The hard drive is formatted in NTFS format. The computer is saying that the Ntfs.sys file is the cause of the problem (except when I go to repair the installation, then the computer won't specify what the problem file is).. Any ideas? <edit> Changed the name of the error to the correct one.
