Hello,
So over the past few days I have been experiencing issues with my PC in that it keeps doing really weird things and I have no idea why. 2 days ago when I tried to play games I would get massive FPS lag spikes every few seconds and it was really annoying. Yesterday when I tried to launch left for dead 2 I got some error and then the screen just went black. After, it flashed white about 10 times and then it closed all my programs and logged me out instantly. So I logged back in and everything was fine until today, when I turned my computer back on, I had a massive black border around the edge of my screen (usually it fills my entire screen but for some reason today it doesn't), the animations are all running slowly within windows 10, all of my games lag (I get about 10 FPS it seems) and one doesn't even open, my connection on the PC is dying (skype lags, downloads go really really slow and it constantly cuts out). I have no idea whats causing any of this but it seems to be getting worse each day.

Before these past few days my computer screen would occasionally just go black and then the PC would crash or it would come back on and give me about 20 errors but these last days have been wayyyy worse. I have scanned everything for viruses etc with norton and haven't downloaded anything fishy or gone on any fishy websites so I dunno whats going on.

If anyone could help I would very much appreciate it!
Thanks in advance!

to me it sounds like it could be a bitcoin miner, using your cpu and perhaps the gpu . try to open your task manager and look for your cpu usage. if check for a task that takes up a lot of cpu usage (20 percent and up)

Hey, thanks for responding.
I checked on the task manager for anything using a load of the CPU and nothing came up - the highest usage was 6% from any one program.
I am currently scanning the system with Malwarebytes and will update you when its finished. Thanks alot!
