Computer getting slower and slower

What is the cause when my computer is runing slower and slower? Sometime it is processing forever.

I have scanned the computer with Antivirus and detected nothing.

Please advise. Thx

If you download a lot of stuff or install a lot of software that takes up memory, than you should consider deleting some things. My brother has Windows XP (I prefer Linux) and his computer suddenly slowed down after using it for like 6 months.

He downloads tons of things so I had to delete software he doesn't even use to free up space.

• Defrag your computer.
• Run a cleanup program like Ccleaner from FileHippo.com.
• Disable some of your programs that launch at startup by typic "msconfig" in the Run box in the Start menu and fixing the settings.
• Check system resources.

If all that doesn't help enough, backup all your data to CD or an external hard drive (or you will lose it), and run your Quick Restore disc that came with the computer. When it restarts, pick the "destructive" formatting option. It will wipe your hard drive clean and make your computer like the factory delivered it.

Wipe and reinstall Windows. If problems still persist after a fresh install then its going to be a hardware fault, and in which case its time to get some hardware monitors to test things like memory (MEMTEST86 if your using 32-bit Windows), hard drives, temps (Everest Home, or SANDRA), GFX (start, run, DXDIAG) etc etc.

It sounds to me like you have excessive load on your system resources. If your computer is locking up at the same point all the time or you are getting memory failed errors, then yes, your RAM might be bad.
