Following the advice below I have closed my original post and added it here.
I have Win XP SP2 and Office 2003 to sp2 loaded. Despite closing all other programs I experience jitters with the computer: When I am watching or playing music on the machine, or even typing this, every few seconds the machine freezes for a split second and carries on. How do I stop this as it is very annoying.
Thanks for the responses. I have AVG anti-virus software installed. NVIDIA graphics card on an AMD SEMPRON 2600+ motherboard with 512MB of memory. I agree it sounds like a memory issue but need advice how to sort the problen out. Running programs comprise AVG, MS activesync 4.1 and the WLAN utility for the WLAN my machine uses. I use the machine with two other user accounts which have limited access only. My account is the only computer administrator. I have no idea how to check what proportion is put aside for graphics.
512mb should be enough to run XP smoothly even with a few apps loaded - even if memory were getting low, it shouldn't actually stop momentarily all the time just work more slowly overall. Your graphics memory is usually only shared with main memory if you have on-board graphics, though the NVidia Turbocache cards do use some main memory to keep the cost of the card down. Indexing/Fast Search may have an effect, My Computer, right click a drive, untick "Allow Indexing service", or switch it off globally (click here). Disable some of the tasks that start with Windows and see if there is any improvement; with a bit of trial and error you might find the culprit. click here
