I have Asus eee pc 900 ha/xp.can I upgrade to windows 7 0r 8.

You are able to download the Network driver by visiting http://support.asus.com/Download.aspx?SLanguage=en&m=Eee+PC+900%2fXP&p=20&s=1. I hope this has helped.

have you reinstalled the video driver? if you've done that and it still does it, the screen on the laptop may be going bad or the lcd panel display cable inside the laptop is pinched or bad. if the laptop is under warranty you have to contact asus tech support. if you're out of warranty, I recommend taking the laptop to a local computer shop for diagnostics/service.

Download the driver from

Good day sir/maam, if you look very close to the LCD, you can see something like windows, but its really dark? chances are your LCD just lost its inverter module that powers your LCD's backlight. visit a local notebook dealer to confirm the problem. Ask if they have sources of LCD inverters for your laptop model. the service and replacement also.

make sure the wireless switch is on you will find it either on the front or sides of the laptop, or can be located near the power button.

Can you use the keyboard? If you can then the mouse software is damaged. If you cannot use the keyboard then boot to safe mode. If safe mode is frozen then the problem is hardware.
