This problem is not very new, and I've experienced as long as I can remember having this laptop. (Only a few months, maybe 5 maximum)
I use Firefox version 3.0.9, and the problem I have is that it randomly decides to give lag spikes. I don't know exactly what to call them, and lag spikes probably isn't quite right, but it's similar in certain ways. Anyways, when doing absolutely anything on firefox, that is, it could be browsing any website, changing my preferences, even typing in a URL, firefox will stall for as low as 2, and up to about 7 seconds, with no activity at all, absolutely nothing on firefox moves at all. If I am in the middle of typing something, it stops printing letters, if I'm watching a video, the current image freezes, but the sound keeps playing as if the video were still going. After those few seconds, it is as if everything that should have happened during that time happened, only without showing it; the text that should have appeared while I was typing suddenly appears all at once, or on the case of a video, the video snaps back up to sync in with the audio, as if it never stopped. These spikes occur quite randomly as far as I can tell, it doesn't seem to matter what I'm doing; in firefox or out of firefox. But it generally can happen 2-3 times in one minute. In fact, it's happened at least 10 times while I've been writing this post (up to this point).
No other programs will freeze (up to this point in my testing), only firefox. I tried opening notepad and holding down a key, and only firefox lagged, not notepad. I tried opening two windows at once, and both freeze at the same time (I don't mean they freeze from the same, certain events; they just freeze simultaneously regardless of their current independent tasks.) I have yet to try using another browser to test this out, but I'm not sure if it's necessary to diagnose this problem. Firefox's CPU use will rise whenever it freezes, up from 20-30 to 50ish percent (while watching an animation in that example).
I've already tried an experimental fix, where I removed "HP Toolbox FX" from the system tray; I read somewhere that it can cause issues, unfortunately, it didn't solve anything.
I have limited knowledge of computers, though more of the software, not so much the hardware. But, I was thinking of purchasing some RAM, not because of this issue, but mainly for games. I don't know if this would the fix the problem in the least, and in fact don't know how much it would benefit me at all. I frequently play games of different intensities, and enjoy having lots of applications open at once, which I have heard is enhanced by a RAM upgrade. I believe it was 50.00 dollars for a 2gb stick, to put into my second RAM slot, in addition to my built in 1 gb stick (bringing the total to 3 gb). So if you feel like answering this as well, is it worth it, or not?
On a side note, I have not restarted my computer for quite awhile, and have kept quite a few windows and tabs open up for about a month, maybe more. I don't know if this is affecting any of this or not, but I do have a lot of tabs open in them.
And on yet another side note, the lags seems to have gotten much more frequent throughout the duration of this post. Now it seems to be happening at least twice as frequently.
I apologize for the long post, I'm horrible at getting to the point.
Thanks for your time.
