Hi, Thanks for the post! Please enter the Safe Mode to check if the issue persists. If the issue disappear, use Clean Boot to find the culprit. If the issue is still there, please use System File Checker to find whether the system is corrupted. 1. Insert the Windows 7 installation DVD into the DVD-ROM; Click Exit if the auto-menu pops up. 2. Open an elevated command prompt. To do this, click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator. If you are prompted for an administrator password or for a confirmation, type the password, or click Allow. 3. At the command prompt, type the following command, and then press ENTER: sfc /scannow Regards, Miya This posting is provided "AS IS" with no warranties, and confers no rights. | Please remember to click "Mark as Answer" on the post that helps you, and to click "Unmark as Answer" if a marked post does not actually answer your question.
