After I updated my windows 7 32 bit to 64 bit, my computer worked smoothly and perfectly fine. However i couldn't play games on it after the update since 0xc00007b error keeps popping up. So i asked my friend and he helped installed a Driver Pack solutions into my computer. From then the frequent freezing problems started. For eg. When opening windows or when i open task manager when an error occurs or after i quit an application. But on the bright side, i could finally play the games on my laptop again. I tried anti virus softwares and uninstalled the driver pack solution application but it does not solve the freezing problem. What should i do?
