Stop cycle of PC crashes
My PC crashed while I was updating Windows and a few other programs. When I rebooted, some programs failed to start and a window opened telling me that System32.dll had failed.
A friend suggested I replace the DLL file and use my Windows 7 disc to repair the hard drive, but the DVD drive won’t read, and an external DVD drive didn’t work either. My friend said the only other option might be to connect my hard drive to his PC and recover or reinstall from there. What did my PC catch?

It didn’t necessarily catch anything – sometimes updates just go wrong for no apparent reason. It’s too late for this now, but for the benefit of others, backing up with a tool such as Easeus Todo Backup Free ( bit.ly/easu446) allows you to restore Windows easily.
There are several possible fixes. First, go to Start, All Programs, Accessories, System Tools, System Restore. Here, you’ll find a list of restore points. Select one that was saved on a date before your problems started, click Next and follow the instructions.
Another possible fix is to go to Start, All Programs, Accessories, Command Prompt. Right-click it and select ‘ Run as administrator’. In the window, type sfc /scannow and press Enter.
A final thing to try is to press F8 just after switching on you PC to summon the Advanced Boot Options screen. Here, you can select either Last Known Good Configuration or Repair Your Computer. The repair option boots into a Windows-like screen with System Recovery Options. Try using Startup Repair and System Restore.
If all else fails, your friend’s suggestion of hooking up your drive to his PC as a second drive may help.
