Dimension 8200 PC Desktop: my computer is slow and it says the virtual memory...
There are many reasons why a computer may lag in performance. You may not have enough computing resources to handle your current computing tasks. Each year, software vendors add new enhancements and security updates to their software packages. The more robust a software package becomes, the more resources (i.e., RAM, and hard drive space) it consumes. So, even with a perfectly healthy computer over time the performance may lag due to increasing computing workloads with no change in key hardware components.
My company builds custom computing systems. I tell all of my customers that the single most computing resource, in my opinion, is RAM. I always encourage them to buy at least 2GB of RAM.
Hard drive space is also very important. As you begin to fill your hard drive up with files and applications, performance may also drop due to a phenomenon called virtual memory.
So, here are my recommendations:
1. Add more RAM to your system. If you're running 512MB or 1GB of RAM, upgrade to at least 2GB. If your motherboard will accomodate 4GB, you should upgrade to 4GB. RAM is very inexpensive these days. Retails prices are roughly $50-$60 per gig. Maybe lower depening on where you source it.
2. If your hard drive is more than 85% of capacity, you should remove unused programs and files. If all these programs/files are critical, I suggest having a local IT provider install a second hard in your desktop chassis.
3. Windows hard drive properties - One of the easiest ways to boost performance of your PC is to use some of the included Windows utilities. If you right click on you "C" drive, you will see multiple tabs. on the "General" tab, you should do a "Disk Cleanup". The disk cleanup is an automated tool that shows you items on your computer that could safely be removed. After doing the "Disk Cleanup", go to the "Tools" tab. Run a "Defragment". After the defragment, you should check your hard drives for errors by clicking the "Check Now" button. The error checking will require you to immediately reboot your computer before the error checking will start. Once your computer comes back into error checking mode, it takes a long time. Roughly, it will take 45 minutes to an hour. When I have customers that have some program working improperly, this is the first thing I run and it has a pretty high success rate.
4. This last option should be done in lieu of number 3 if you have some time on your hands. Backup up all your data and reinstall everything on your hard drive. Most manufacturers have recovery tools built into your system. Or they supply you with recovery DVDs. Its a lot of work installing everything again, but your machine will run like new.
5. There are many 3rd party tools that claim to optimize your PC, but I don't have any first-hand experience to give a recommendation.
