Hi Jane,

You either have a loose connection, or a bad inverter board. The inverter board acts as a power supply for the lcd backlight, and is located behind the Acer logo at the bottom of the lcd. So.....when the screen flashes off, can you see if there is still an image on the unlit screen? If so, it's very likely the inverter board. Inverter boards are not expensive (in Canada, an Acer service centre pays less than $10 for the part). If you cannot see any image on the unlit screen, It's likely a loose connection, or the lcd is on its way out. Let me know if you can see image on the unlit screen........

Regards,

Joe

Hi there.

All you should need to do, is download and install the Chipset drivers for your laptop. You can download them from here:
http://www.acer.co.uk/acer/service.do?LanguageISOCtxParam=en&miu10einu24.current.attN2B2F2EEF=3734&sp=page15e&ctx2.c2att1=17&miu10ekcond13.attN2B2F2EEF=3734&CountryISOCtxParam=UK&ctx1g.c2att92=122&ctx1.att21k=1&CRC=2980211862

Just select your make and model of laptop, then just underneath that, select your version of XP. Then it will list the drivers underneath. The Chipset drivers should be about second from bottom, click the orange icon to the right, and then click Run. Reboot your system, and now check to see if it's all sorted.

Hope that helps

Tim
