After installing Windows 7 updates, I got an onscreen message that an update was available for Adobe Air. Was not familiar with this program, so checked it out; it seemed valid, so I installed the update. Shortly thereafter, I got a BSOD. Restarted the computer in safe mode, tried to uninstall Adobe Air using Control Panel Programs & Features; got an error message to the effect that I could not uninstall without Administrator privilieges (which is very strange since I am only user and AM the Administrator. My husband suggested just going into the C drive in My Computer and deleting it the old fashioned way, which I did. Also deleted Air from Recycle Bin, so it should be GONE. At first, it seemed to solve the problem; computer started up as normal, and I was able to go into other programs. However, BSOD returned. My husband restarted and ran Norton Quick Scan, then restarted; again, computer started up but soon returned to BSOD. On one of these forays, I noticed something about a corruppted driver, but it did not stay on the blue screen long enough to determine what it said. Now computer turns on, but even Windows open screen does not come up. This is a brand new Lenovo X1 Carbon 20A7 (one without actual FN keys -- these are the adaptive type, so not really sure that "clicking" on repeated F8 is leading to Safe Mode; in any case, computer appears to turn itself off after a couple of minutes.
Now I really don't know what to do -- I would suspect a defect in the computer, but it seemed to be working fine prior to update of Adobe Air. Right now, I'd be satisfied just to be able to get into Safe Mode. Any ideas???
