The Motherboard is also new, (and might be the problem, too) and it is the MSI Z97-G45 GAMING motherboard.
The RAM is 8gb]
The Disk is toshiba DT01ACA100 (1TB)
I did have an add-on graphics card before, and do now (nvidia geforce 750 ti)
I am trying to run a variety of games, such as Counter-Strike: Global Offensive, TERA, Dark Souls II, etc
I am running windows 10 on top of all that,
The only thing that I have messed with in the BIOS is the boot option of Legacy and UEFI because it wouldn't start in UEFI mode.
Have you updated the BIOS? Since you have a Haswell refresh processor, many of the motherboards that support this processor required a BIOS update.
I found two entries for your board: MSI Australia
Look for the latest bios for your board at the link above, and update your BIOS using the recommended procedure for updating your board. As always, you should make certain that your data is backed-up.
I seem to have encountered yet another problem.
When i try to update my BIOS through the MSI Live Update 6 program, it does not update.
I have tried to update through windows, and had to wait about 30 minutes until realizing that nothing was going to happen.
When I tried to update through the USB, everything seemed to have worked fine, but when i went to check if i still needed to update, it said i still had the previous version.
