Why does my hard drive run constantly - even when I am not in a site or doing anything on the computer.....?

Try doing a de- fragmentation. Then go and clear all the temporary Internet files out. You may find that you have a spy ware programme on your comp. Do a spy ware check with yahoo Anti spy. It may help. I have a registry cleaner on mine and that takes a lot of disused stuff out as well. McAfee should have stopped any viruses, worms or trojans So I cant see it being that.

maybe its due to slow or faulty ram or you have used up all your hard disk space

Your hard drive has nothing to do with the internet since it's always spining even if you're not on line,the noise you hear is probably the hard drive is wearing out,eventually the noise will get worse and more constant,maybe it's time for a new hard drive

Sounds like Spyware. Download Both Adaware and Spybot Search and Destroy, install them and run both and see what pops up. \n\nThen after it runs defrag your hard drive and you should see marked improvement.

It may be that your harddrive is starting to encounter problems. However, the usual case is just what it said: low space. You can backup some info you use infrequently to another hD or Disk (cd or dvd). If you haven't run a Spyware check u might want to do it as well. I recommend Spybot Search and Destroy. Just don't forget to UPDATE it before running it. Good Luck

run scandisk and make sure you check the option to scan the surface area for physical damage.  If your computer seems to be running slower and there is a kind of grinding noise coming from the drive, it's probably time to replace it before losing all of your data.

There may be many reasons for this problem. I can give you a link that deals with hard drive problems. Some hard drive problems can be easily fixed yourself by using easily available tools. I found the info at http://fixit.in useful

I think you may just need to clean out your PC.\n\n1. Defrag your PC.  (Start > Programs > Accessories > Systems Tools > Disk Defragmenter)\n2. Give your PC a good spyware cleaning.  Use Windows Defender for this (http://www.microsoft.com/athome/security/spyware/software/default.mspx)

Is it a old computer?  How much RAM are you running?  Could be that you have spyware and malicious programs running in the background that you are not aware of.

There is a very strong possibility that this answer could be wrong!\n\nHigh usage of the HD indicates that some programs are running on your computer.  Even if you are not doing anything on the machine, programs could be running in the background.\n\nCheck your task manager to see what is active.\n\nIf you are running winXP then check services.\n\nYou may also be using too much memory.  Again check task manager.  An over active HD could be page swapping to use virtual memory.\nYou may need to buy more memory.

Scan your computer often for adware, spyware and viruses.\nAlso use a firewall... and to prevent it slowing down, defragment your hard drive every so often.

Sounds like your hard drive is gettin ready to take a dump, burn all your files that you want to keep before it does!

1. You probably have too much crap running in the background for one thing. Check to see whats running in startup. Most people dont understand that having these things run eats up valuable ram! If you have things running you dont use then shut them off! The more ram you have available the faster your system will run. \n2. You may be one of the many users who insist on downloading free music. Believe me nothing is free! I have found , bearshare, kazaa, limewire, etc. all are infested with adware, spyware, trojans, hijackers, and viruses! Anyone who tells you they arent is an absolute idiot!\n3. Online games, porn sites, gambling sites, etc are also infected with this crap! \nDownload yahoo antispy and run it. I am betting you find tons of this crap! Once your computer is back to par dont go back to these sites!

have you deleted files , scaned your disk , did a disk clean up, defragged lately.. those things can slow the comp down, if not done weekly.. maybe you need more ram.. did you update before you ran your virus scan.. sometimes all you need 2 do is reboot.. bummer eh

You can also do a disk check. Go to My Computer-C:Local Drive-right click on it-properties-tools-error checker.  Check both boxes in error checker. You will have the option of closing windows now and run the disk check, or the next time you start your computer. Do this when you are not planning on using your computer for awhile, as this process takes up to 1-2 hours. You will not be able to use your computer, but the screen will let you see the scan process for your files, etc. I do this at least twice a month. Also you should scan for adaware,viruses, etc. daily. They too can slow down your computer. Good Luck

Do you have an up to date anti virus prog installed ?\nHave you anti spyware programs installed.?\nDo you know how to Defragment your computer ?\nDo you know how to use disc clean up ?\n\nIf you answer No to any of these questions then  there is a big possibility you have either a virus or spyware or overloaded hard drive.that is causing these problems.

not very often only whenyou absolutely need to... try running a defrag to improve performance.
