This is going to long winded with a load of questions, so I'll post my spec.

When I built the computer I had a ton of problem with freezing and crashing. In the end it turned out to be the graphics card and I was given a replacement. After doing more research I wish I had never bought the Gigabyte GPU.
Another problem I've had is that I've never been able to run my RAM in XMP mode, the machine can run fine for days but then crash.

Machines been fine for months but it seemed a little slower in games, could have been my imagination. But I decided to give the RAM XMP another go, but before I did I made sure my BIOS is up-to-date (F50a).
Machine ran fine for around 7 days.
Then 1 day, I was playing a game and watching a friend steam a game through discord, suddenly everything slowed down and froze.

I did a BIOS reset to get everything back to default but I kept getting problems, the machine was trying to boot into Windows but was taking ages and then would just sit at a black screen, monitor would say no signal.
This went on for best part of 30 min, me completely powering down the system and trying to get back into Windows, even went inside and pulled out the BIOS battery.
Finally got into safe mode, but Windows froze once I put my password in.
I had practically given up, but for some reason it booted into Windows normally, though it took a long time.

Machine continued to work afterwords, but still had an insanely long boot up time of 2 minutes 30 seconds. A minute and a half of that was spent on the BIOS splash screen with nothing happening. Also my Blu-Ray playing was only working intermittently, sometimes not being recognised in Windows, or take over a minute to eject.
I went inside, checked all the connections, turned the machine back on and it booted into Windows in under 15 seconds.

That was about 5 days ago, today I did a fresh install of Windows, since it's been about a year.
Straight away, I had the slow bootup problem again, but checking the cabling once again fixed the fault.

So I'm back in Windows, downloading all my stuff and I could use some help and advice.

I've downloaded the AMD drivers for the motherboard (AX370), latest Radeon graphics driver and all the Windows updates. Windows seems to have all my other drivers easily enough, is there anything I should be downloading?

Regarding the latest craziness I had, what do you think could be the problem? I put it down to overclocking the RAM, but once the BIOS was reset, everything should have gone back to normal?
I was ready to blame the graphics card once again but I'm not sure anymore.

With the RAM and XMP, I know XMP settings aren't guaranteed, but after paying £200 for RAM, I'm more then a little disappointed that I'm stuck at 2400.
Would a newer motherboard be a sure fire option? I've been looking at 470 motherboards.

Is there a benchmark I can use to check that my machine is running at full speed? After all my problems, I'm a little paranoid that it's slower then it should be.

I'm still new to the world of dual monitors, I use the MSI Optix for gaming because of the higher refresh rate, but I'm not sure that some of my games are playing in full screen mode, even though I have it enabled. If I pause a game, I can still move my mouse cursor from 1 screen to another, is that normal?
