Drastic Slowdown in Windows 7, Windows XP and Windows 7. PLEASE HELP

[Snacks]

Hello. I noticed some slowdown immediately after startup on my laptop. I tried installing 3 OSes, all with the same results. After a couple of days, the computer will work for a couple of minutes, then DRASTIC SLOWDOWN that makes the computer unusuable.

A quick note: When I went to install each OS, even that was slow (I.E. the install windows were slow to come up, overall slow) I suspect hard drive failure.... Please help, as I'll be needing this computer for school soon.

The HDD speed is 5400RPM.

And what OSes did you install and in what order?

It came with XP Pro. Since I didn't know the pass, I did a fresh Win7 install. From there, I couldn't make my mind up between Windows 7 and Ubuntu, and was switching with a fresh install every 2-3 weeks for a few months. I first had slowdown in Ubuntu, tried reinstalling it, then Windows XP, then 7. I managed to get XP on it right now, but it's still having that problem.

Snacks,
do you have Win 7 DVD? Yes/No

Run this program on your computer and tell me if it says that all is perfectly oK or conditionally or not at all.

I don't even think I'll be able to get to that, but I'll try.

The last time I installed Win7, it worked perfectly, everything was perfect.

Again, I'm currently running XP.

The test came back and it's all fine. All hardware is compatible.

My recommendation:

Install Win 7 and only Win 7.

You have zero need for eXPired.

After you get a stable WIN 7 only system AND you have used Win 7 Backup and Restore to create a System Image, consult the tutorials here BEFORE installing UBUNTU.

I'd take this advice, but there's one problem. When I go to install Win7, the install windows come up very slowly and I've yet to get it installed since I tried to install it after I experienced slowdown in Ubuntu.

Null Problemo! We have numerous tutorials on making a clean install covering every possible situation.

Supposedly the motherlode of these tutorials is:

the approach is going to be to first wipe the disk clean and then perform the install.

[FONT=&quot]CLEAN A HARD DISK PRIOR TO WINDOWS 7 INSTALL USING YOUR WINDOWS 7 DVD[/FONT]​

TURN OFF THE COMPUTER WITH THE DVD TRAY OPEN
Ø Turn on your computer.
Ø Open the DVD door.
Ø Turn off the computer with the DVD door open.

BOOT FROM YOUR WINDOWS 7 DVD AND GO TO A COMMAND PROMPT
Ø Insert the Windows 7 DVD and close the DVD door.
Ø Power on your computer.
Ø When that very first dialog appears where you would normally push the NEXT button, then use the SHIFT + F10 key combo to get to a command prompt.
Ø The command prompt will be X:>


USE THE DISKPART PROGRAM TO “CLEAN” THE HARD DISK
Type the commands shown, hitting the Enter key after each.

Do not proceed to the next command until the current command is finished.

· DISKPART (the command prompt will change to DISKPART>)
· LIST DISK (this will list the disks present)
· SELECT DISK 0 (assuming disk zero is the desired hard disk)
· DETAIL DISK (this will show you info regarding the disk you selected)
· CLEAN ALL (this is the command to write zeros to entire disk)
This can take half a day for a 2 Terabyte disk.
· EXIT(this will exit you from the DiskPart program)
· EXIT(this will exit you back to the Windows 7 install program)

===============================================================

Now that your back in the Win 7 install program, you can continue with the install like normal. All signs and traces of everything is gone from your disk since each and every byte was overwritten with zeros.

That simple procedure is how I perform a clean install of Win 7.

Test your hardware before installing: run HD Diagnostic extended CD scan for your make, followed by RAM - Test with Memtest86+ for 5-6 passes.

To prepare your HD you can get by with Diskpart Clean Command since it provides the only therapeutic benefit by overwriting the boot sector, while Clean All is only needed to make data unretrievable by most forensics.
