Hello, I am going to start out by saying that I am not tech-savvy. I don't know much about computers. So I apologize if I sound stupid. So basically, it started with the computer freezing up. I woke up one morning, and moved the mouse to wake the computer up (I never turn it off completely...That might be something that caused the problem in the first place,who knows). The screen came on, and I could see the desktop and the mouse, but the mouse wouldn't move, and the keyboard wouldn't do anything. I tried to turn the computer off by holding the power button, but that wouldn't do anything. So I had to turn off the power manually. When it booted up again, it was fine. So I left for work. Then my boyfriend woke up, the computer was still fine. He played WoW, checked email, went on the internet, and then left to go shopping. I got home from work and moved the mouse to wake up the computer. The screen came on to only the background picture of my desktop. The icons and mouse were gone. Again, I had to cut the power to reboot the computer. It booted up again and tried to run a disk check or something in BIOS or DOS or whatever it's called before Windows starts up. It froze mid check. I had to reboot again. This time, it wanted to run a virus check in BIOS. Again, it froze. I had to reboot. When it booted up again, I declined for any checks to happen. Windows started up. I ran a registry check, and it was fine. Ran a virus check, and it was fine. Thought maybe it was just a weird fluke, so I went about business as usual, going on the internet and checking e-mail. I went to the kitchen to get a snack, and then came back, and the computer was frozen again (on the desk top, mouse visable, but not moveable, no response from the keyboard). I rebooted. Pressed F8 and chose to run Safe Mode. Froze up while loading. Rebooted. Pressed F8 and chose to Run Last Successful Boot Attempt. Froze. Rebooted. Much of the same as above, etc. Finally, one attempt worked and the computer loaded. By this time, I had to leave again for a friend's birthday. I came home late and just went straight to bed without checking the computer. This morning, I woke up to find a blue screen with an error message. I didn't writ down what it said unfortunately. Had to reboot. Now, every time I reboot, the same thing happens. "NVIDIA Boot Aget 249.0542 Copyright etc Copyright etc Port 01: Reset Port Error!! Port 02: Reset Port Error!!" "CLIENT MAC ADDR: 00 1D 72 A7 0F E9 GUID: FFFFFFFFF-FFF-FFFFF-FFFFF-DHCP......." And it just stays on this screen forever. My specs: ACER Aspire X1200 Windows Vista Bios version R01-A3 I don't know what to do. The only things my computer will allow me to do now are choose a different boot method (hard drive, NVIDIA Boot Agent or Plug-In/some other term) or go into Setup, which has options for BIOS and other stuff. I didn't want to fiddle with anything here because I don't know what any of it means. Any ideas? I don't even have the Vista CD to reinstall anything. Should I include any more information? Please let me know. Edit: So I just tried to start up the computer again. I let it sit for about an hour before trying to start it up again. It asked what mode it should do (Safe, etc, Normal) So I tried safe mode. It starts to try safe mode by Loading Windows Files, but freezes at avgidesh.sys I had to reboot. This time, before it could ask me how to load, it said "One of your disks needs to be checked for consistency" So I let it run a check. "CHKDSK is verifying files (stage 1 of 3)" and it's fine. Then, "CHKDSK is verifying indxes (stage 2 of 3)" and it freezes at 28 percent (261974 of 319480 index entries processed).
