Hi-I have an Acer Aspire 5920g laptop that is displaying a white screen on startup.The problems started a few weeks ago when no display at all appeared on the monitor after startup-just a blank black screen. I replaced the existing graphics card with a compatible Radeon Express PCI ATI Graphics HD 3650 HD3650 DDR2 512M / MXM II Video Card and now a totally white screen appears shortly after power on(after approx 10 seconds).The Acer logo briefly appears and I can get into the bios but the white screen appears almost immediately.I can hear the laptop powering up and the DVD drive will open/close as normal. There are no beeps on startup and all lights are lit as normal.
I have hooked up to an external LCD and can briefly get the BIOS page on the external LCD but then the signal is lost on the external display(after approx 10sec). I have checked all connections to the laptop monitor and all seems ok.I have tried reseating the memory modules to no avail and am now at a loss as to what is causing the problem..Any help would be much appreciated.
Thanks in advance
