Sorry to read you hae this issue but it's clearly in warranty so why not use the warranty and get it fixed.
Keep in mind you didn't reveal if the machine was subjected to anything odd like torrents or installed any new apps or virus.
I recently bought a laptop running windows 8, but yesterday i tried to start it and got bsod. I tried restarting a couple of times but it kept showing bsod. I get error code 0xc0000185. I wanted to try restoring it to just after I bought it, but I cannot even start it in safe mode to do this. Has anyone here had the same problem? How can I fix this? Do I have to restart windows or is there another way?
