Hi.
The below is some advice about the currently installed memory on your Father in Law's machine...
Random Access Memory Advice:893.76 Mb Total Physical Memory | 109.20 Mb Available Physical Memory | 12.22% Memory free
Though Microsoft claims Vista will run with a mere 512MB or 1GB installed depending on the version of the Vista Operating System in use...in my humble opinion a minimum of 2 GB is far better.
If you wish to upgrade the installed memory,
Crucial have a small scanner(CrucialScan.exe)which is perfectly safe to download and run. Which will advise if the system can support any upgraded memory modules. They cater for the US/UK and Europe.
Next:Going back to the Taskbar issue, try the advice on this page...
Unlock and move the taskbarIf still no joy check Quick Launch is not active and if it is remove the feature, then try and move the Taskbar back to it original position. To remove the Quick Launch feature...
Right-click on the
Taskbar >>
Toolbars > >>
Quick LaunchFinally if still unable to move the TaskBar, reboot the machince into Safe Mode, then back into Normal Mode and try again.
How to boot into Safe Mode:Restart the computer and as soon as it starts booting up again continuously tap the F8 key. A menu should come up where you will be given the option to enter Safe Mode, do so.
If any problems refer to this
