AcerPower 1000 -- VERY slow loading

Your machine is old, there's not much you can do. Remove any programs you don't use, stop programs from starting-up with the OS, and increase your RAM: http://www.crucial.com/index.aspx

Start the computer.
Select the "old" system, and then repeatedly press F8,
until you see the Windows Start-Up Menu (white text over a black background).
Choose Start In Safe Mode with Command Prompt.
At the command-prompt, enter 'FORMAT C:' to "wipe" 100% of the files from the disk-drive.
When it completes, turn the computer off.
Turn the computer on, and boot from those original "System Restore" CDs.
It will load Windows onto your now-empty disk-drive.

There are a couple possible solutions to your problem. If the computer will still turn on and load windows, and I assume you are using Windows XP, you can try doing a system restore. To do this, go to Start, Programs, Accessories, System Tools, and select System Restore. If system restore is enabled, you should be able to choose a date in the past when the laptop was working properly and restore the computer to that date. If you want to completely reload windows, you will need a Windows XP installation disc. Load the disc in the CD or DVD player and reboot the computer. You should see a screen asking you to press any key to boot from CD, go ahead and press Enter. You will now enter setup where you can reformat the hard drive and reload windows XP. Follow the on-screen instructions to delete any old partitions, and then create a new partition and format it using NTFS. The windows XP installation will continue after the hard drive is formatted. If, when you reboot the computer with the installation disc in the drive, you are not prompted to boot from CD, you may need to reboot and press F2 or F12 to change the boot selection to the CD or DVD drive so it will load the CD first before it tries to load your original Windows installation.

You need to completely reinstall Windows...

first of all why are you seeking to restore windows?? if it is because you want to restore all settings well just go to:

START>ALLPROGRAMS>ACCESSORIES>SYSTEM TOOL>SYSTEM RESTORE

then select the date of which you want to restore your installation..

but if you want to restore your windows because of a recent crash or recent virus activity i would not recommend doing so cause it would be only a tempoary solution, that the problem would arise again sooner or later, a complete re-format would be a good choice

mostlly this happens when you downloaded a corrupt file, anyway let see if we can fix it using the restore mode, if you're already familiar with it try to restore it using the date before the game was installed if not follow these instruction.

1. upon bootup press "F8" and wait for the option that lets you select some option such as safe mode, safemode with networking, etc, etc,

2. select the "safe mode", your pc will load with only minimal option a popup box will appear asking if you're going to use restore mode. (if your pc crashes before it loads the system stop rigth here, your system needs to be reformat, otherwise pls proceed)

3. click "START", "Program", "Accessories", "System Tools", and then "System restore"

4.popup box will appear select ok or continue until you reach the calendar option that will let you select the date you want to restore in an earlier time, pls select the date before you install the game ex. you install the game on 10/15/09, then select the 10/14/09 or later then select ok or continue until it reaches finish.

5. reboot the pc, this should solve your problem

Boot in safe mode

hmmm... try turning it on then while it's booting windows forece the computer off.
then turn it on again and select launch startup repair. you can try everything from there.
hope this helps!
