First, right click on My Computer, properties, and it will tell you processor and RAM. If the OS (Windows XP, I assume) recognizes the RAM, it is using it.
RAM increase (bump from 512 to 2GB) will work if your PC was full of cruft (polite word) and was swapping pieces of memory to the pagefile.sys due to lack of RAM. I have seen a lot of PC’s like this. What you want to do is minimize the crap on your PC. I find a lot of stupid programs like:
HP Advisor - notifies of updates to an HP PC;
Samsung updater for DVD-writer, tells me when updates are there for the drive’s firmware(??!)
Update notifiers also for Java, Adobe Reader and Flash, ITunes, etc. Even WIndows Update.
Windows Firewall - turn this off when on your home network with a firewall/router (for a laptop, leave it on when you out at Starbucks!)
Stupid add-ons - Google or Yahoo or other toolbars for IE (IE - Manage Add-Ons); do you really need a toolbar ofr browsing?
Stupid extra programs - i.e. some people love Snag-It and other copy-and-paste programs.
Any other background processes that gobble memory and processing.
Look at the icons in the tray on the lower right, by the clock on your task bar. How many of those functions do you really need? (I.e. Safely Remove USB hardware - yeah, keep that…) Figure out how to get rid of the unnecessary ones.
Task Manager will show you running processes and how much memory they consume.
When in doubt, search google and see what 4 or 10 others say about whatever process before stopping it.
Go to Trend for free Housecall download or Malwarebytes or similar anti-spyware scanner. DOwnload the freebie scanner, and be sure your system is clean. Then uninstall the program; if necessary, keep the installer you downloaded and reinstall to do this check every few months.
(Note - nothing is both free and easy. Except Suzie Mitchell, but that’s a different thread… Read the page fine print while downloading and be sure what you click on. They will try to convince you or trick you into downloading the paid/trial versions, or running extra add-ons. You just want the free scanner tool. )
If you do not have an anti-virus program, AVG is free and does a good job. Good enough that the pay programs tried to convince us that it was useless…
If you are not computer-savvy, research carefully before killing any process that may be critical to windows.
It’s not surprising boot time is still slow. Basically, all this crud loads from disc, so no matter how fast your processor, the disc is still slow. Maybe you can find a substitute disc that is much faster than 2006, but the R/W speed may also depend on the controller chips. Plus, then you need someone to copy the disc image across.
I ran across an issue the last 3 years or so - if you have windows updates on, your boot may be painfully slow; even if you have “download but ask me when to update”, Windows Update will catalog your whole software configuration and determine what has outstanding updates - every time you boot. Someone with a 2006 machine may wait for 15 to 20 minutes before they can do anything useable after boot, especially with WU checking every install and your anti-virus scanning each of those files as they are opened. You click on a program and 2 minutes later it starts to open… Turn off all updating and just do it manually every few weeks when you can go make a cup of coffee while waiting.
