I have a desktop computer that is/was running Windows XP pro. It was running off a 200 gig maxtor SATA drive perfectly fine for about 3/4 a year until yesterday, when a blue warning screen popped up, and before I could read it my computer restarted. When I try to boot up my computer, I get a black screen saying that windows could not start properly, and gives me certain options, (Start windows normally, use last working settings, safe mode, safe mode with network, and safe mode with command prompt) I've tried every one of these, and all that happens is windows tries to load and my computer restarts. I've called places for help, and my analysis right now is that I need to repair some windows files. When I try to do this, with my XP disk, I get to the point where windows is checking my drive, and then I get a blue warning screen telling me that windows was shut down to prevent damage, and it also says this, although I don't know what it means: DRIVER_IRQL_NOT_LESS_OR_EQUAL It also says viaraid.sys at the bottom, which I believe is the driver for my SATA drive. So, basically, I have no idea what I should do next, can anyone help me?
