I, recently upgraded my Acer system seven to eight months ago. It has an Intel Core 2 Duo processor, 2 GB DDR 2 RAM, and 320 GB hard drive. It was working fine for the last seven months, but all of a sudden it starts giving "Generic Host Controller" errors while surfing. Using the DOS window, Windows closes in just five to six seconds. I can't run C++ compilers and environments.
To overcome this problem, I formatted my C drive and installed a licenced version of Windows XP and also activated it. On the second day, the same problem occurred. So, I tried enabling system restore, but it is shown as disabled by group policy. I have tried to enable system restore using the gpedit . msc command, but it doesn't work. I have formatted the system again. At present, the system is running normally and system restore can be done also. I have checked for virus also. System doesn't have any viruses. I have created two system restore points, but it is of no use in case "system restore disabled by group policy".
