Original Title: code 52
I was on youtube and i noticed weird white line flashing on the screen so i closed Google chrome next i opened Minecraft and it said "bad video card" i read on the internet that it had to do with with my video card or graphics card driver and it had to be updated so i opened device manager and went to display adapters and saw a yellow triangle and an exclamation point inside it. the yellow triangle was beside "AMD RADEON HD 7520 G so i clicked on it and pressed the update button and it said allready updated or something like that. then i saw that it said
" Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)"
also when i turned of my PC and it was on the black screen a small square the color of my start screen background (blue) appeared for like 2 seconds and then my PC turned of. i turned my PC back on and shut it off again and it kept happening. First time this happens. does it have to do with the video card problem.
is this something i can easily fix or do i have to go best buy toget it fixed or buy anything

It sounds like your video card got damaged for some reason
Toshiba should repair it for you for free if it's under warranty
Also if you want to update your drivers in a future time
Device Manager may not always detect the latest drivers
You should download latest drivers for your graphics card from AMD.com
Or use AMD Driver Autodetect and it'll install the driver for your computer
See if you can run System Restore via the Advanced Repair options and use it to get back to when things worked.
