    Ok so this problem is driving me nuts. I use an old Compaq presario 2100 laptop with an amd processor. In the last 2 weeks this computer has been running like shit. Internet is slow as hell and the computer in general just lags. My cpu fan is always on, and the task manager says my CPU is at like 80-100% when I am doing nothing.

    So far I've:

    Installed spybot and ran a search and there were no infected files found

    I've re-installed the OS.

    I run a pirated version of windows XP pro that my buddy made. It has been working great for the last year.

    What could the problems be? What else can I do? Possible hardware problem? HELP!

    Spybot is pretty much obsolete. Follow this guide http://forums.majorgeeks.com/showthread.php?t=139313
    If you've reformatted your system already and the problem's still there, then it's probably just the old hardware reaching the end of its life.

    Thanks. Exactly what I was looking for.

    I'll give the guide a shot, but I fear that it's simply due to the old hardware failing.

    If the fan is always on it might be an idea to try and get dust out of it. Could be packed in there pretty thick.

    Do this.

    Laptops will build up a ton of dust in the heatsink and a quick shot of compressed air will usually fix it right up.

    I took it apart and cleaned it and blew the old dust away with my compressor. Still runs like shit. I think it's just time for a new laptop. I read somewhere that old hardware performs bad because of corrosion or the humidity takes its toll. I fucked up my space bar in the process as well.

    What do you guys recommend for a new laptop?

    I just want to surf the web, play some online flash games, look at porn, type papers for school. No hardcore gaming.

    I have the exact same laptop at my house (presario 2100, amd 2800+, 512 ram, Windows XP, etc)! I just did a reformat (for the first time ever) about a month ago. It's running pretty good again.

    I still have about 1.5 hour battery life on the darn thing too!

    I get through about 75 minutes of a movie on Windows media player before it shuts down :bowrofl: This thing wont die!

    How did you initially start the re-install?

    Did you turn on the laptop with the CD already in, or put it in after it had fully started up?

    I put the cd in,
    restarted,
    booted from cd,
    deleted the old partition,
    re-installed windows xp on the blank partition.

    The task manager doesn't say which process. Under the "performance" tab it says that CPU usage is 80-100%. There are lots of processes that are running. I tried deleting some of them and the computer started acting funny.

    So should I just reformat? How do I do that?

    .

    What is using the processor? Something is using it and you should be able to find out.

    A few things here. It sounds like you have already reformatted your computer. If you deleted the partition, created a new partition and then installed XP onto that, then you have reformatted.

    If you get into the task manager, go to the processes tab, and sort the CPU amount by clicking on 'CPU' at the top. Then you should be able to track what is using 80-100% of your computer!

    Once you do this, post up what it is and then we may be able to help you get rid of it or fix it :)

    Also....if you did a new install of XP onto this machine, chances are you did not install the necessary drivers for your computer. This machine (2100) has an ATI onboard chipset, LAN, audio, and other drivers that will not install correctly when you reformat. I remember when I did mine, it could barely even scroll through a simple text web page!

    Go to this website (http://www.compaq.com/country/cpq_support.html) and click on 'software and driver downloads' and input your computer product number (tip: its not just 2100, look on the bottom of your laptop and there is a service tag that will say something like...2108US *this is what mine says). Then download AND install all of the drivers on that page.

    Post up if you have questions :)

    Ok, got it. The one that is using about 80-90% is called "System Idle Process". The username is "SYSTEM". Mem usage is 16K.

    I have no idea what this is. What should I do next?

    Oh and yes, I have downloaded the correct graphics driver already. The audio didn't need a driver, it works fine.

    well if you reformatted it looks like you're fine. "System Idle Process" is a windows program that runs when your system is idle in order give accurate measurement of CPU time that the rest of the processes use. It has the lowest priority of all threads. Looks like you should be in the clear now and everything should be running alot better. Next time look in taskmanager and find out what process is using the most cpu time besides system idle and look up how to remove that process which will usually be a virus/worm. It will save you a reformat.

    edit: reset i meant reformat

    My old work lappy did the same (Dell inspirion 6400). replaced all removeable hardware (mem/hd/etc) and it still would use idle @ 95%.

    I used it as target practice and got a new laptop.

    The system idle process exists because a CPU isn't able to do nothing, so the OS gives it the system idle process to run when it has nothing else needing to be done.

    Run HDTach and HD Tune on the hard drive and see if it's reporting a bunch of errors or dropouts in transfer speed. Bad hard drives can bog the shit out of a computer.
