I'm having an issue with my (new-ish) work laptop. Every once in a while it will freeze up - but not in the usual way. The keyboard and mouse work. Any applications that are already open will continue to work - I can send emails, flick between applications etc properly. However, I am unable to open any new Explorer windows (ie. clicking on the Recycle Bin, or Computer in the start menu does nothing). I can't start any new applications. I can't even tell the computer to reboot. Task manager refuses to open. What on earth is going on!
I have checked the memory (memtest86+), run
chkdisk, system file checker, and uninstalled all but the most essential applications. What can I do now? I've tried "Process Monitor" but I'm not sure how to use the logs to find the fault.
Laptop is a Core i5 Lenovo W530 running Windows 7 (x64).
