basically my computer has stopped working for the last 2 weeks. all of the sudden 1 day it froze and than when i rebooted it it would not load in normal mode.i noticed that when this problem started there were strange green lines in the background of the screen which had never been there before. when i load in safe mode they are also there.
i dont know a whole lot about laptops, but from what i have found im starting to think this is a hardware problem. when in safe mode all the images are much more pixalated and glitchy, along with the strange green lines in the background. so im beginning to think this is a video card problem. but i just dont understand how that can be the issue when 1- my computer stopped working for a week, than worked for a week, and than stopped working. i never changed anything this all just happened out of no where. 2- why would my graphics card stop me from running windows regularly. 3- why would i be able to run in safe mode if my graphics card was the issue?
ive had my laptop for about 3 years now and never had any major issues. no viruses or anything. and as soon as this issue started i ran everything i had to see if that was the problem, but i found no infected files.
any thoughts or ideas on whats going on would be greatly appreciated
if that is the case, how much do you think it would cost? i think my laptop costs me around $1,000+ so i mean i have to imagine unless replacing the motherboard/video card cant be as expensive as buying a whole new system.
ive heard that most laptop videocards are intergrated, but im not sure if mine is. im currently using a sony vaio model vgn-ar670 and my videocard is an nvidia geforce 8400M GT.
