Well, my harddisk is working and working and working, and everything is really slow.
All the time, I hear the computer working in the background. I've tried to restart the computer twice, but it doesn't fix it...

I think the harddisk is working instead of the RAM, but I have no clue why...

Anyone knows who to fix it?

By the way, when I was about to click the submit button, firefox stopped responding, and I had to wait 15 secs. (and then I wrote this paragraph)

Hmm, it sounds like you have some kind of process eating up your cpu power and harddisk usage. If I were you, I would try to scan for adaware or any other malicious spyware/software/program that might have been recently installed without your consent that might be starting up with your computer. Then, you may want to run a disk defrag. It is possible that you might have not done this in a while, but sometimes just running helps things be put back in order. If you need any help, please post back. I am sure that I or somebody else here will be more than willing to help you. Good luck!

Virus?

Try and see what processe(s) is taking up the most CPU in the Windows Task Manager>Processes tab. Maybe that bit of information can help the more technical minded ones here.

I've already told you that my CPU and RAM are fine, the program that uses most RAM now is Firefox (19MB) and the used CPU never goes above 10%.

Ohhhh ooops I actually forgot to tell you that.... But now you know it anyway

You said that it could be that your HDD is being used rather then RAM, that sounds like a possability, or that your page file is set to dynamicayl resize as it sees fit, so my fisrt question is, DO you have enough RAM? and two what OS are you running, I'll tell you how to check your page file on Win XP the process varies slightly for other OS's

1)Go to the control panel, the precess varies depending on your start menu layout.
2) I use classic view in the start menu, so on winXP for the time being swich to classic view
3) Select the system icon
4)I have SP2, and can't remember if this changes with the update, Choose the advanced TAB
5)In the preformance area choose Settings
6) Choose the advanced tab, and at the bottom choose the change button, I use the set memory option, general rule of thumb set the max and min value to 1.5x your current ram, unless you don't have near enough ram then doubble or tripple it, (make sure you set enough, if you don't the computer might not come on!)
7) okay out and then restart the computer

As good as that sounds you may want to try the spyware scan, that does sound like the better option

ameribass' suggestion for a diskdrive defrag should be on your priority. also, might as well clear out your harddrive for unnecessary files, in case you are running out of disk space and it would surely slow down your PC. but in the likelihood that you are using a drive with huge space still available, maybe you can consider the possibility of partitioning it into smaller partitions if you can (be careful on this one, as partitioning is supposed to be done most effectively on a clean/newly-formatted harddrive; otherwise you may lose precious data. backup, backup, backup.).

Well, I have 512 MB ram. That thingy you talked about was at 756MB, so that shouldn't be any problem. But I don't think it's a spyware or virus or something like that, as I already said, the program that used most RAM was firefox, and my CPU usage never goes above 15%. So something is probably wrong with my system, which is a Windows XP SP2.



Yes, I have only used about 10-15GB of 160GB, so it shouldn't be a problem.

Oh I wasn't able to split the harddisk into smaller partitions when I got the computer, I don't know why though.

And merge these triple posts

Would you post your computer spec? That would help if you post what OS, what AV do you use? An misconfigured Avast! could use your harddisk all the time generating VRDB.

PS: Does your Harddisk work when the computer is idle
