Windows Vista is and always has been a "memory hog". Meaning, it uses "ALOT" of memory just to run.
When Vista was new, alot of manufacturers put the "Recommended System Requirements
", as listed by Microsoft, in machines. These machines ran decent in their native form. That was without all of the extra programs that you as the user
installed after purchasing the machine. The best thing you can do to help your computer is install more memory in your computer as cryptodan and keny111111 have both suggested.
I would also recommend a Defrag and Temp file cleaning as you have probably accumulated some extra unneeded "stuff" over the years.
I myself have used MyDefrag
and have had very good success with it on my Vista machine and also run TFC about once a month to keep the cobwebs cleaned out.
Directions for TFC are as follows:
Please download TFC
(Temp File Cleaner) by Old Timer and save it to your desktop.alternate download link
* Save any unsaved work. TFC will close ALL open programs including your browser!
* Double-click on TFC.exe to run it. If you are using Vista, right-click on the file and choose Run As Administrator
* Click the Start button to begin the cleaning process and let it run uninterrupted to completion.
* TFC will clear out all temp folders for all user accounts (temp, IE temp, Java, FF, Opera, Chrome, Safari), including Administrator, All Users, LocalService, NetworkService, and any other accounts in the user folder.
If TFC prompts you to reboot, please do so immediately. If not prompted, manually reboot the machine anyway to ensure a complete clean.
Note: It is normal for the computer to be slow to boot after running TFC cleaner the first time.
Hope this helps,
