Do you have a HP Computer problem? Does your problem relate to slow performance, freezing, random error messages, blue-screen error, or is it booting automatically. If the answer is “YES” then I highly recommend reading this HP repair blog.
Understand the type of problem. If all was well a while back, and the problem started just after the installation of a new software or driver then say “No” to the change. Uninstall those there can be compatibility issues. However, if it doesn’t bear result then best is to go for system restore.
It will restore system files to an earlier point without affecting your files, such as e‑mail, documents, or photos. Do it as: click the “Start” button. In the search box, type “System Restore”, and then, in the list of results, click “System Restore”. Enter administrator credentials, if asked for.
Windows Memory Diagnostic Tool will be the right one to check and fix memory related issues. It brings notifications related to errors, and you can double-click those to fix instantly. Action Center available with your Windows 7-based PC is a good platform to address security related errors. Use Disk Clean up and Disk Defragmenter tools to fix disk errors and keep everything organized on the system hard-disk to enhance accessibility of program and files.
If you are a real performance enthusiast, then I will suggest disabling features such as UAC (User account control), Aero, Windows 7 Sidebar, Aero Peek, Windows 7 Password Protection, unwanted system sounds, and uninstalling unwanted Start Up Items, etc.
Hope, this HP help information will give you relief in difficult situation.
