White Screen on Laptop but External is Fine?
My windows 7 professional 32bit on my laptop has a problem. Everytime I turn it on, my laptop screen is white (and fades in some hints of black) and nothing shows up. However, sometimes I am able to get a display on an external monitor.
Before my computer loads my desktop it does a startup repair. What ends up happening is that it does a system restore and my computer is able to boot up normally on my external monitor (laptop screen still white). Once everything loads, my computer automatically looks for and installs a VGA controller driver (at this point I am suspecting something may be wrong with my graphics card because I no longer have the windows aero theme).
Once the VGA drivers are installed, my computer says it has to restart so that changes can be made. After the restart, everything is back to normal with my laptop screen working again and now I have the aero theme again. What is the problem? I've been trying to fix this for weeks. It should be noted that I can't always get the display onto my external so I have to keep on force restarting (holding onto the power button) until I can get it on the external.
I installed a new driver for my graphics card and it hasn't fixed the problem. I know there is a virus on my computer (file is tdx.sys). I am going to replace that file with a new one following some instructions from another forum but I don't want to do that yet because I am currently writing exams and not much of a tech savvy person. I don't want to mess around with system files until at least after my exams so I can back up everything. What I am hoping for is maybe another way to fix this problem because the virus may not have to do with this. Would love to hear some suggestions!
Thanks everyone!
