A couple weeks ago, I was getting c0000221 errors and I had to reformat. I got them today but checkdesk fixed it when rebooting.

Now, my computer runs slowly when browsing the internet. Its "choppy". Its more of a scrolling effect that has snags rather than smoothly going through a webpage.

Am I explaining my problem correctly? Its strange. Everything is new as far as components. There is literally no software on the computer except microsoft office.

And now Im back to random reboots

Event viewer is showing following errors

Several times ntfs
