Hi everyone
I have Toshiba Qosmio G20 laptop which i have had no serious problems with since purchase about 3 years ago and this morning it went crazy on me.
Before i start explaining my problem i apologies if i dont make sence, its quite complecated to explain, anyway so here i go.
The problem that i am having is that when i boot up my laptop the Qosmio logo appers fine and then it goes into the password screen (this is the hard drive password NOT the windows login screen.) The password screen normal is a black screen asking for the password but now the whole screen is full of white pixles and about 3 M letters where it ask's you for the password. When i enter the password it then goes into the windows load up screen and on this screen there are various green/blue virtical lines on it. When it finally loads the screen just goes black and nothing happens but i can see the hard drive working. I then have to do a hard shutdown since there is nothing else i can do.
What i then decided to do was login using safe mode. Once i had entered the hard drive password i pressed F8 and was presented with the screen where you pick how you would like to start windows. This screen was again filled with white pixles all over the screen and the letter M was all over the place as well. I could not make out which one was safe mode but i knew it was the first one so i selected it had loged in. It went to the windows load up screen again with green/blue virtical lines and then it went into the login screen. It seemed to work in safe mode but there were still green/blue vertical and horizontal lines which can be seen. I then restarted the laptop again and pressed F8 but this time i decided to login using the Enable VGA mode.
When i done this upto the windows login screen it was the same but when i loged into windows there was no green/blue lines and it seemed to be working fine but the max resolution i could go to was 800x600 and if i did select this the screen would blink every 5 seconds or so.
After a bit of googling i updated my BIOS, display drivers, scanned for viruies but nothing, i just dont know what it could be. I initally thought it would be the screen but it works fine in VGA mode so now im thinking that its the video card but im not sure. And also when i rub the back of my screen it feels weird like its vibrating or something but thats only when i have the AC adapter in, any ideas?
If it is the video card can i replace it? if so how much would it cost?
Thanks so much in advance for any help.
