Possible causes::

1. Virus / Spyware / Malware
You may have a virus or spyware not wanting you to change your firewall settings and thats it's way of saying no.

Run "Malwarebytes Anti Malware" and make sure you let it update first/

2.> Corrupted files / data sectors on your hard drive
You may have some lost allocation units or bad sectors on your hard drive and it just happens to be where some of the files to access the expert settings of your firewall are sitting..

tell your system to run a "chkdsk /f" at a command prompt, your system will tell you the drive is in use and cannot run would you like to run at next startup.. tell it yes and re-boot alowing it to run the scan in it's entierty.

DELL INSPIRON 1410 idle process takes high processor usage and heats up my pc

If running Windows OS - there could be several background processes running causing this higher CPU usage.
Hitting 'CTRL/ALT/DEL' will bring up the task manager (Win98/WinXP) or a Menu which has task manager (WinVista/Win7/Win8), you can then see what background programs are running.

Keys keep freezing when writing fix for free

I am assuming you are using windows XP?
Go To processes...
Check the CPU usage at the bottom

If you have no programs running, the cpu usage should be around 3%

if the cpu is low and not over 75%
the next thing you need to check is the space left avaialble on your hard drive. at least 15% should still be avaialble. on a 80GB it would be good if you have about 15 to 20GB free.
to check click my computer... from the start menu
click on drive C:
right click on property and check the space available.
Once I have more input from you about these 2 issues, I can direct you to a working solution.

High cpu useage

Open the Windows Task Manager - you should be able to right-click on the bottom task bar to do this or else, you can use Ctrl + Alt + Delete keys to invoke it too.

In the Task Manager window, select the Process page tab, then click on the CPU column header and sort the list of running processes by the amount of CPU being used - this should help you understand what is consuming high CPU on your computer.

Slow running of window vista

There are many things that might cause your PC to run slowly or restart at time and then. It could be a fragmented disk; fragmented registry; a virus, Trojan, or spy ware; high CPU and/or utilization due to too many programs running; high disk I/O; or something else.

To check your CPU and memory utilization, run Task Manager. You can start Task Manager by pressing CTRL+ALT+DEL and then clicking on the Task Manager Button. In Task manager, click on the Performance tab and check CPU Usage and PF Usage. PF Usage is an indicator of memory usage. If one or both of these is high, click on the Processes tab, and sort the columns by CPU or Memory to see what processes are consuming the resource. If you are not sure what the process "Image name" is for, Google the name and you should find what the process is for.

If your CPU and memory usage are reasonable, then you may have a different issue. Even if you running anti-virus software, it may be beneficial to scan your PC with another scanner to check for viruses. Here is a few good virus scanners that you can run to check your PC:

I am on my own laptop but need to burn a disk with some form of laptop doctor so i can load it onto her laptop to work out why it is freezeing after 5 minutes

Start the laptop, and as soon as windows starts, hit the
CTRL-ALT-DELETE , buttons, this will bring up task MGR,

it will be on the process tab, click -show process from all users at bottom, Now watch the percentage usage of all the process's, its best if you make this full screen so you can see all of them, something is probably running and causing it to freeze, now at the bottom it says CPU usage, if this stays under 20% and the laptop freezes, something is wrong besides a program or windows program, usually.

You should do this first, its probably a program spiking the cpu and causing this.

Most disk's that you are asking about are for a specific problem.
They might not help for a freeze.

You can wait for someone to post something.

If you find the one that is causing the spike of CPU, restart it, and do this again, but this time right click on the process and pick end process, this will stop it from running. If you post what the process
is, we can let you know what it is and how to correct it, hopefully.

Sorry, That I don't have some cure all disk for windows, if there was one they would be the richest company along with microsoft.

My HP dv6700 freezes up after I have signed on from the password window. It works find in the Safe Mode but will freeze up after a couple of minutes sitting idol or if I try to work on any program or on...

I would advise to bring up the task manager (right click on the Windows bar across the bottom of your screen and select task manager) then click on the Processes tab. From there you can see the percentage of the CPU being used and Memory being used. System Idle Process should be high for CPU usage, but if you have anything else that seems abnormally high, look up that process online and see if it's safe to kill it. You can also sort the CPU and Memory columns by clickingon the column at the top.

If a process is holding you up and not essential to Windows. You may want to kill the process and uninstall the program that the process belongs to.

Gaming issues

I would make sure you have the latest bios, and video drivers to start. Make sure you have all latest updates for windows. Make sure your hard drive is defragmented. Also make sure your computer is clean and that it is ventilating/cooling properly. If that fails I would just format and reinstall windows.
Hope that helps,
