Multiple programs have started acting up, can't find root cause

OK, first build, almost a year in. No problems until recently, but I can’t seem to pinpoint what is the source of these problems. And they seem to be happening more frequently. Please read through this and give me your best shots. I’ll be very grateful!

Thank you guys for your replies. I am sorry it took me so long to get back, but I have had to work.

To answer your questions, yes I have checked my SSD with chkdsk, but the results were normal. And the problem persists. Also, I have been told that SSDs don't really need chkdsk, but I ran it anyway.

Any other ideas?
