<human>: saved up for months to upgrade my woefully underpowered gaming rig. I spent over $300 for a new CPU, motherboard and RAM so I could play all these games i've been wanting to play but couldn't. 

Now I can't play ANY games. After 3 days diagnosing a faulty memory stick I got Win 7 x64 installed as I planned to use 8gb of RAM. Now it seems all of my hard drives are not working. I do a scan with auslogics and it says in the disk errors section "critical" I try to fix it but nothing.  

Windows won't update, it keeps saying it has to revert to previous settings. Nearly everything I install gets an error when trying to start or just gets the error "this program encountered an error and had to shut down" 

I am infuriated and frustrated beyond reason. My computer is what keeps me sane and a $40 part is standing in my way. I'm depressed from taking care of my mom who has Lupus and a prosthetic leg and not having a life or job of my own. Thus why it was such a big deal to be able to save up the money for my computer. I enjoy being able to spend some time with my friends online and pretend i'm not a 25 year old failure who is living at home and taking care of his mother who get a little worse every day and there is nothing I can do to stop it.

Can you provide a brief overview of the text?
