my system is unbeleivably slow???

I was running xp prof sp2 with 1 gb of pc3200 memory on an asus k8v mobo, with a 2ghz processor, and was consistently getting lags, my windows would take forever to open up and when typing the letters would appear a few seconds after typing them, stuff like that, I removed the memory I had because it was paired when i purchased it and I bought 3 1gb sticks of pny pc3200, I still have the same issues but now it is worse, I have run spyware(spysweeper, adaware, and spybot, and I have kaspersky av installed, does anyone have any idea what could be causing this. thank you in advance

 

thanks, I have a 750gb HD with 250 free, I am running firefox instead of IE, I increased the pagefile to the max of 3072mb I have disabled the unnecessary startup tasks, I will run the online virus scan and update on results, thanks

 

When was the last time you installed your operating system fresh? Pete's suggestions are all great but there could be countless things that could be causing the problem. If you haven't done a fresh install in a couple of years, it's possible that your OS is pretty "trashed ".

Chances are, as in most cases, your problem is software-related and there's a very good chance that a full reinstall of your OS would solve your problem. When I say a full reinstall, I mean wipe the partition and start completely fresh just in case you are "infected ".

I would see what virus scans say about your machine first though, of course.

 

os was installed fresh about 6 months ago, funny thing Is I removed one stick of ram giving me 2gb instead of 3 and it is running better

 

no I have checked the memory requirements of the mobo and the pc3200 is fine, in fact pc3200 is what has been in it I just upgraded.
