Games work for a while then crashes

I downloaded Microsoft security essentials. I'm worried if I buy norton anti virus I will still have a problem. Error codes suggested I put in windows DVD n upgrade so I'm currently doing that and waiting for it to finish
 
I only have security essentials installed. Any program u reccomend I install?

Upgrade finished n when windows loaded back up. A Microsoft .Net Framework box opened up mentioning setup has detected .NET Framework version 4 needs to be repaired. Do not restart until setup is complete.

It's been on this setup window for the past 30 minutes
 
Its going bad. I ended task for the setup. Went and downloaded .NET Framework for site. Ran a repair install and it failed to repair.
 
I'm afraid that this isn't a memory issue. The update problems point to the "real" issue here. Is your copy of Windows legit?
 
I had a tech store install it for me and they discounted me mentioning a problem with Firefox randomly crashing. He was testing it the morning I picked it up and said it hasn't done it since. He also mentioned that he thinks its the ssd. But according to you it's not. And I think you have a better idea what's going on than that tech store I went too.

I was gonna buy a new ssd from them and they said they would clone my ssd for free.
 
You have a nice system... This may be a simple bios setting. Is the SSD connected to a SATA 3 port and is the SATA controller set as AHCI?
 
Yes both my ssd and hdd are in sata3 ports and set to AHCI. I just shutdown my computer instead of restarting and now it has my updates installing before shutdown......
 
Manually restarted since it wasn't installing. Booted up with no desktop background n no Internet n eveything looked old fashion so I did a system restore. I give up already, I should just throw this Pc out the window
