I moved my computer from a desk to a different position, all went smoothly and gently however when I restarted it the mouse didn't work and was accompanied by a 'USB device has malfunctioned' error message. I put the mouse into a USB on the front instead and it worked. I then found the keyboard wasn't responding either so moved that to the front USBs as well - both now worked.
The computer was unresponsive so I switched it off but when it started up it went to the BSOD which flashed up way too fast to read before being replaced by a Windows Error Recovery which gives the options of Launch Startup Repair or Start Normally. I went with Launch Startup Repair. This tells me it can't repair it automatically and gives the details of:
The Windows Repair Problem Signature
Problem Event Name: StartupRepairOffline
Problem Signature 1: 6.1.7600.16385
Problem Signature 2: 6.1.7600.16385
Problem Signature 3: Unknown
Problem Signature 4: 21199352
Problem Signature 5: AutoFailover
Problem Signature 6: 6
Problem Signature 7: BadDriver
OS Version: 6.1.7600.2.0.0.256.1
Locale ID: 1033
What I've tried so far:
Disabled autorestart to see the BSOD, just says runs Chkdsk
Starting in Safe mode - goes straight to BSOD
Run chkdsk from the command prompt. (It started in X: so I changed to C: which is my bootable) - 'Windows has checked the file system and found no problems'. I then changed back to X: but 'Windows cannot run disk checking on this volume because it is write protected'.
I've seen other threads that have managed to recover from this type of error eventually but is it less painful to just reinstall windows? There's no data on C: that I'm worried about - it's a 128GB SSD and all my important stuff is on other drives.
If reinstalling is the simplest way, how do I go about it? I have the product key (probably!) or could upgrade to Windows 8.
