If you have a Acer Aspire One laptop and it freezes suddenly, this post can help you :
Machine : Acer aspire one D257 with 1 GB RAM, Windows 7 Starter preinstalled.
CPU : Intel Atom N570 (1.66 GHz, 1 MB L2 cache), 1 GB DDR3 memory, 250 GB HDD.
The machine hangs when installing Office 2007 through wireless. It froze again at the second attempt , at a different point.
You must manually power off the laptop by pressing the power button for a few seconds. Windows complains about not being shut down properly. No errors found in Event Viewer. I also used memtest to check the RAM.
After a brief search , i found a solution in this forum : the wireless adapter (or at least it’s driver) – when it’s used for large file transfers it causes the computer to freeze.
I tested this by copying a movie over wireless and it froze again. I couldn’t try to repair the laptop because the owner said it won’t use the wireless for large transfers.
But my suggestions are : use another wireless driver, test using a Live Linux CD, play with settings for the wireless adapter in Device Manager. Maybe try an upgraded version of Windows 7 (32 / 64 bit Home / Professional / Ultimate).
If you solved the problem i expect feedback.
