i bought a used laptop and it was great until today when it went to a black screen and says it is not genuine. Read some threads and mtk 2.4.3 and it says can not activate product. Any ideas? c
If it was me I would wipe the HDD and install a brand new OS. Then you know what's installed. Then for you I would suggest to use Daz's loader. There are plenty of threads where you can find links to download a clean untouched Win 7 image.
