If the number error message are the numbers which include many zeros, well these change depending on where the antivirus programme I am running freezes.
Yes, usually a combination of zeroes and maybe an x and other numbers.
Being a complete computer novice makes even looking for the Hard disk space a challenge.
Click the Start button. Click the My Computer entry up on the right. My Computer should show disk drives. Right-click on the C: drive. Choose Properties from the bottom of the menu. You will now see a small popup window with a pie chart and it will tell you how much disk space you have, and how much disk space is used.
Also can I find chkdsk on my system?
Yes, the same way. Now that you've got the C: drive's Properties window open, click on the "Tools" tab, and you'll see two main choices: "Error Checking" - this is chkdsk, which is a vastly improved version of the chkdsk in Windows NT and a close cousin to Scandisk from Windows 95/98/ME.
Below that, you'll see the disk defragment tool.
If you don't have enough space on your hard drive to run error checking, you may find yourself in a continuous loop and unable to get back into Windows. It will also limit the ability to use a pagefile, which is the NT/2000/XP version of a swap space on the hard drive. This is necessary to run programs, start Windows, and so on. That's why you need to check space first. If this is a relatively new computer, you might probably have 80% or more of your hard disk space free. If this is an older computer that has been upgraded to XP, it is quite common to have very little space left because the drive is smaller and it doesn't take long to fill it.
In error checking (chkdsk) there are two choices:
Automatically Fix File System Errors, and
Scan for And Attempt Recovery of Bad Sectors
If you choose the second choice as well as the first, it may take a very long time, because this checks the entire hard disk for bad sectors. It depends on the size of the drive and the speed of the computer. This check can only be run when you restart the computer because it will not work while Windows is running. It will ask if you wish to run when you restart, and you say yes. (If you've already checked your space and found a sufficient amount. I would personally like to see about a gig of free space, though you could get by with less.)
It's a good idea to run the recovery of bad sectors sometimes, especially on older drives, which may be starting to fail.
When chkdsk runs, it will only have a blue screen with white letters and will report the progress of the various parts of the scan, then Windows will restart.
After running chkdsk, you can go back and run defrag. Depending on how often you run it, how fast your computer is, and how much data you have, it can take from minutes to hours to complete. If it's very fragmented, there will be a lot of red showing. If not, it will show a lot of blue. Analyze first, then defrag.
The blue screens you're getting could be the result of corrupted files, or they could mean bad memory or a hardware conflict. This is where the error codes can help to diagnose. Also, there is something called the event viewer that may shed some light on your problems. Go to Start, Control Panel, Administrative Tools, Event Viewer.
Click on each of the items in the left pane to view errors in that particular area. In the right pane, you can double-click on the errors to get more information about them.
