Once in a blue moon my acer aspire one likes to turn off when it gets to the main window screen. This is the second it happened, I tried rebooting it, unplugging the power cord, and removing the battery and putting it back in. But somehow there's no change.

There is a good chance of still getting a blue screen with a OS upgrade. You should try a clean install. Then try testing the RAM. Leave one DIMM at a time and swap to one slot at a time. This may help identify a bad one.

Hello download or renew the missing drivers here at acer:

http://support.acer.com/product/default.aspx?modelId=35

Please select your windows system.
Unzip the file before you install the driver.
Reboot after the install is done.

Try to renew the screen card driver.
Blue screen of death is always a faulty driver.

Good luck

You can use a torrent site like isoHUNT, to download a copy of the Acer OEM vista disc, this is a little illegal, but if you use your own Windows key from your COA sticker, it should register and activate ok.
You may have to download your drivers seperatly from from ACER.
You will need a torrent client like UTorrent, and the download could take a day or so

That "Blue Screen" is also known as "Blue screen of Death".

The problem is due driver compatibilty or unstablity.

Try to boot your system to "Safe Boot" by pressing F8 during startup.
Select "Last know good Configuration that works"
Check if it can take you to desktop.
Unstalled the wi-fi driver and reboot.

If the above procedure fails, again
Try to boot your system to "Safe Boot" by pressing F8 during startup.
Select "Safe boot"
Check if it can take you to desktop.
Unstalled the wi-fi driver and reboot.

Now create a restore point  and download the lastest version of your WI-Fi driver and installed.

This should work fine.

Otherwise Backup all your important data from your hard drive (mainly opearting system file installed drive usually C:\) and go for a new Installation.

try resetting bios by unplugging computer, hold power button for 30 seconds and try again, update and I will try to help [email protected] rate me please

When you boot up start pressing F8 and you should get a Windows startup page with more options. If you do select Safe Mode
When windows has loaded, goto MSConfig and select Diagnostic Startup. Ok and reboot
See if windows boots normally.

If it's still under warranty call Acer, it sounds like a bad hard drive to me.

check whether the hdd is detecting on bios

You may have a corrupt driver, go to this site and down load vga driver, as i cannot see a grphics driver for your system http://support.acer-euro.com/drivers/notebook/as_1400.html
