Alright so last night I pulled on my headset coord with too much force and it pulled my entire computer tower over, it hit the ground on the side that the motherboard rests on with some strong force.

So it killed my ram, I knew that since I was originally getting a BAD_POOL_CALLER seconds after startup, so I replaced the ram boom I thought I was good to go. Nope.

Now after about 5 minutes of using internet explorer I got another blue screen SYSTEM SERVICE EXPECTION. No fuckin idea. Also upon restart I receive this message:

I have attempted to repair the computer and it didn't detect any problems.

I'm not sure if this is because of the shitty version of windows I'm using or what. Also when I attempted to install Firefox it said something like "this is not a valid windows 64 package" or some bullshit, don't quote me on that because I can't remember the exact message.

Help would be appreciated!
