How do I delete my operating system?

I have a pirated version of XP Professional on a Dell Inspiron 5000 with an Intel Pentium III w/597 mHz and 320 mb of ram. I have been getting an lsass.exe system shutdown message regularly and just want to clean house and start over with a licensed operating system. How do I clean everything off of my computer after I've saved everything that's important. Please help. Thanks.

Since you aren't giving the computer away, you don't have to go through a long procedure of erasing all your data. Just pop in the legit Windows XP disk, and install it. The installation software will walk you through it...just make sure you select reformat when prompted.

Hope this helps,

Hi , I am very new(newbie) at computers and retired as well. My question of you is off topic, quite often I see people refer to bios settings and to read or change them. How does one get into the bios screen?
I'm having an unrelated problem with ram and was told to change some bios settings, but I don't know how to get to the bios section??

Yes if he didn't enable emailing

In reply to: OK thanks ...BUT

in his profile.

What you can do, using search, is in one of his most recent posts, Just advise him/her about enabling email in his/her profile.

In the same message you can make your comment. Then that thread will pop up to the top of the first page of that forum, and it might be read by the person.

Many people simply don't take time to update their profile, may be afraid that someone will get their email address [which they won't] and don't know that they can limit the numbers of emails that they will accept in a month.

Computer Bios

In reply to: to Frank

Hi Jeff, Been away from the computer all day so I just now saw your post.

You can enter the BIOS setup usually with one of the following keys or key combos while the computer is starting to boot:
Usually when you are first booting up, the first screen will display in text which key(s) to press to enter setup.
On some machines, you have to hit ESC first to clear the manufacturer's logo.
For an AMI BIOS it's usually DELETE
For an Award or Phoenix BIOS it's usually CTRL+ALT+ESC, F2 or DELETE
For a Compaq BIOS it's usually F10

You do need to be carefull of the changes you make as it can cause problems, just remember them so you can go back and re-do them if need be. Any changes made need to be saved.

That is what I needed to know. Things like this are easy for people involved with computers, but being new how does one learn? But this is off topic and I will shut up for now, on this string at least.

No problem

In reply to: THANKS

When you get into the BIOS, navigate with the up/down arrows and make changes with the +/- keys. after the changes are made press the ESC key to return to the main menu, you may have to use the Enter key to enter sub menu's. Post back if you need more info.

To reinstall Windows...

In reply to: to Frank

1.In Windows XP: Plug in a flash drive or external hard drive (or a floppy disk if you really want to). If you want, you can also use a blank CD-R , as long as you have a CD burner(CD-R/CD-RW).

2. Open the My Documents folder, as well as any other folders that you have files stored in. Open My Computer, and find the HDD, floppy, or flash drive you want to use. If it's a CD, then double-click it to get to a blank burning folder; XP can burn CDs.

3. Drag and drop all files into the folder from My Computer.

4. Click Start>Programs and make a list of all programs you have installed.

5. Make sure you have the driver install CDs handy, they should have come with the computer.

6. Insert your legit XP disk. Restart the computer.

7. When the DELL(tm) logo appears, start hitting the F2 key repeatedly until the Dell screen disapears and a screen like this one appears: (pic here

8. Push the arrow keys to get to the Boot menu. Press the indicated keys to move the CD drive to the top, then the HDD. (pic here

9. Push F10 to save changes and exit the BIOS.

10. When the "Press any key to boot from CD..." message appears, press any key (or just whack the keyboard like I do, as it'll hit a few random keys).

11. Once your computer gets to the screen "Welcome to setup" press ENTER.

12. Look at the license agreement and push F8 if you agree.

13. You should now be at a step for partitioning. Push D to delete the partition, the L to confirm. Then push C to create a new one. Push Enter. Choose to format with NTFS (Quick) and push enter.

14. Wait a while. Your computer will format the Hard drive, copy files, and then restart. When the "Press any key to boot from CD" message appears, DON'T PRESS ANY KEY. The computer will say "Microsoft Windows XP" like the startup screen.

15. The computer will now boot into the second part of second. Here you have the graphical interface and mouse. Follow the steps, they're pretty obvious. For the TCP/IP networking one, leave it at the default. Know that your computer's name CANNOT be the same as the user account's name.

16.For the workgroup or domain, leave it at the default workgroup unless you're sure of what you want it to be. this can be changed later if necessary.

17.Your computer will restart.

18. If asked about screen resolution, click Ok, the ok again.

19. Finish the rest, then click Finish.

(pics )

20. Restart the computer. Press F2 to enter the BIOS as I said earlier, go to the boot menu, and set the HDD to be the first boot device. Remove the XP CD. Press F10 to save and exit.

21. You computer should load XP. Login.

22. Insert the driver CD, and install drivers as indicated here: (

23. Plugin the flash drive, external HDD, floppy(s), or CD that you used earlier for your data. Open My computer, or use autoplay if it comes up to get to the drive. Copy all of your files back to the places they were like My Documents.

24. Look at your list of programs that you made, and download or install them from the CDs.

You should now be finished reinstalling Microsoft Windows XP!

Can you re-post?


Posting in this old thread and many members will 'walk on by' when they see the age.

Your best bet is to create your own thread, describe your system as requested in the red note above each submission window, explain the problem, then others are sure to try and help.

Good luck.

when the setup prompts you for partitioning, MAKE SURE TO DELETE ALL PARTITIONS AND THEN CREATE ONE NEW ONE (NTFS quick or FAT quick) RATHER THAN LEAVING THE EXISTING PARTITIONS OR INSTALLING OVER ANOTHER PARTITION!!! It is critical that you do so to make sure you do not end up with multiple Operating System Installs on the computer!

How can I delete one of the Operating System?

In reply to: How do I delete my operating system?

Just a point the lsass shutdown that pops up normally indicates that the system has a virus, probably one of the 'Blaster' versions. So make sure that you fully format the disk and if you have backed up any info, check it for viruses before reinstalling it!

In reply to: How do I delete my operating system?

There is a useful utility called KillDisk which you can download to a floppy which, which automatically runs on boot-up and wipes everything off you drive. The change bott-up to run from CD and install your new XPpro and then spend ages downloading/installing Microsoft's security and SP2.

Isass virus

In reply to: How do I delete my operating system?

I have Norton and AdAware. I run both regularly and nothing is found. Norton updates frequently. However, if I have to use Windows Task Manager to stop a program that stops working I see Isass.exe as one of the programs running, 00 CPU usage, 1080K, and USER NAME "System". Does this mean I still have the Isass after I paid a chunk of money to have it removed? I, too, am thinking of changing my OS but this worries me now.

When I try to install XP get to the licence agreement to agree press F8 try to press key board won?t no response I have a USB KB and a old connection. When I press esc to abort install key board works no problem. Any help would be great. Reg JA Basically I want to do a complete clean install.
