Hi, the title sums it up, but I'll explain. Yesterday, my family got a USB Mobile Broadband Dongle (3 is the network) for our computer. We'd never had broadband before on this computer. Anyway... Today, I was helping my younger brother make a Facebook profile when a message popped up saying something like 'Windows has applied an update, and requires restarting the computer in order for the update to take effect'. I chose to restart later. A few minutes later we'd finished, and the same message popped up once again. Since we'd finished, I said 'Fine, just restart it now..'. When I did, I got a message saying something like 'Windows did not shut down successfully.' (I can't actually remember what it said, but was given several options of starting Windows). I chose 'Start Windows Normally'. I was then greeted by a blue screen reading- Code: A problem has been detected and Windows has been shut down to prevent damage to your computer. If this is the first time you've seen this stop error screen, restart your computer. If this screen appears again, follow these steps: Check to be sure you have adequate disk space. If a driver is identified in the stop message, disable the driver or check with the manufacturer for driver updates. Try changing video adapters. Check with your hardware vendor for any BIOS updates. Disable BIOS memory options such as caching or shadowing. If you need to use Safe Mode to remove or disable components, restart your computer, press F8 to select Advanced Startup Options, and then select Safe Mode. Technical Information: *** STOP: 0x0000007E (0xC0000005, 0x8053616C, 0xF7A31508, 0xF7A31204) I'd used Google to look around for a solution, and was lead to a page on this site. I can't currently find any disk that came with the computer, but upon accessing the Recovery Console... C:\WINDOWS>chkdsk /r... The bold text being what I typed. I waited for that to finish and got a message along the lines of 'One or more errors has been found and corrected', amongst numerous values for volume, or something. However, still nothing. When I restart, the same Blue Screen is there. My friend recommended uninstalling the Broadband Modem, but I'm not sure how to do that from the Recovery Console (as I can't access regular Windows XP). I really need serious help with this, please- sorry if I shouldn't have posted this. Also, though a format would be a drastic step (in that everything is deleted), would I be able to start again with my PC, as the day I first started it up? I just need to make it work normally, really, but preferably without having to buy anything extra or something- however, I wouldn't rule that out. Please, could somebody help me fix it? EDIT: I'm so sorry, I noticed the BSOD section just now.. On my mobile screen earlier I hadn't noticed it, so... Sorry for the waste of bandwidth, guys.
