I got a Dell desktop before I started college, that was a few years ago. A couple months ago it got the blue screen on startup and I didn't care too much since I just use my fiancee's laptop. But today I pulled it out to see if I can get it going. On startup, before the loading windows screen even comes up, I get the blue screen. It says (besides the normal stuff) UNMOUNTABLE_BOOT_VOLUME and Technical information: ***STOP: 0x000000ED, (0X81EEBAD8, 0X0000006, 0X00000000, 0X00000000) If I hit F8 on startup, I try to start it in safe mode, but it still does the same thing. The last thing it does before the blue screen is when it's loading the drivers. The last one to appear on the screen is ...\system32\DRIVERS\AGP440.sys Then I tried something else. After hitting F8 on startup, I hit it again. That allows me to load windows with the last known good configuration, but it still does the same thing. I don't know where to go from here.
