My laptop was working fine last summer until the Windows Genuine Advantage kept popping up telling me it wanted to verify if my OS was valid. I tried to shut it down or disable it and windows started to behave strangely to the point that it would not load at all. I purchased the laptop in December 2008 from Micro Center in Houston brand new. I have the sticker on the laptop that tells me the OS is valid. Lenovo did not ship with the rescue and recovery disks, instead it has a rescue partition. The rescue partition would not restore the laptop. So I tried the rescue and recovery DVD I created. Somehow it did not create the product recovery CDs. When I called Lenovo about this problem, they belittled me and then charged me $50 for the set of Product CDs. I thought my troubles were over, wrong! After installing the CDs windows almost loaded and then it went to the blue screen of death. This happened a few times. I tried reinstalling the disks and everytime I would receive a different error message, it is missing drivers, it can't locate a file, etc. Today it returned: The application or DLL X:minint\system32\umpnpmgr.dll is not a valid Windows image, Please check this against your installation diskette. Product Recovery could not find file Z:\UBREC.CMD I called Lenovo and again, no help. I am at a loss. My laptop was fine until the Microsoft Genuine Advantage pop-up kept showing up. And Lenovo is not providing any support for the faulty CDs they sold me. Can someone help me?
