I don't believe there's a similar thread.
I used to hibernate my Win 7 without problems. But 2 days ago, I noticed that the wireless internet connection became very poor and when I resume Win 7, I get the black screen prompting me to start Win in safe mode or normally. I thought it was a drive issue. I formatted the C drive and installed Win 7 again. The internet is working better, but I still have the same issue with hibernation. No other issues with the performance of the system.

Any suggestions?
