Different types of computer crashes

Hello!

In recent months my computer (2.5 years old) shows three different types of "crashes" and I have no idea what causes them, maybe someone here knows how to trace the source of them; not sure if they are all related.

1) When I leave the computer for a while while turned on the monitor will sometimes go inactive (stand by? screen goes black, ON/OFF-LED light blinking) and the PC is still on (LED on). It will not react to any kind of input from mouse or keyboard and I have to reboot it via the ON/OFF button.

2) Usually during gaming but also once while browsing the computer stopped accepting any kind of input (about 7 and 1 times respectively in the last 3/4 months maybe). The screen doesn't freeze, games will keep running, audio playing, people hear me on skype, I just cannot move my mouse or type. Again I have to reboot via the ON/OFF button and I do see how the PC exits all programs while it's shutting down.

3) This is the newest type of crash I encountered and the most frequent one recently. Usually in somewhat heavy use (by no means too heavy for my system though; for example 1-2 videos open and few tabs (max 8), 0-1 game, 1 music player) the screen will refresh (go black and back on) and I get a popup saying "Display driver AMD has stopped responding and has recovered". Some open windows and sometimes the task bar tend to have some minor graphic bug so I have to minimise or close the windows or change the user to get the display right again.

I'm not really sure what could be wrong, the PC is not that old but it seems graphics card related to me? I did update its driver but don't know much about computers and am not too keen on replacing hardware to find the source this way when the crashes only occur maybe once every 1-2 weeks.
My system consists of i5-3570k, Sapphire AMD HD 7850 (both never overclocked), MSI Z77A-G45 (one circuit has a scratch but it was one for the sound I believe and everything was running fine for two years), Corsair CX 500, Corsair RAM and some hard drives that I changed and the crashes occurred before and after I did this.

Thanks for any help!

Since you have an integrated GPU on that i5, try uninstalling all AMD Drivers and running off the integrated graphics, that may help eliminate a couple things. (It's 11PM here in Australia so I'm off to bed, hopefully someone can come along and pick up where I left off, good luck!)

Well, these crashes only happen once or twice a week (and only force me to reboot) so I wouldn't see if this fixes everything except if I use the one from the CPU for a longer period which isn't really an option, I need a better graphics card for my uses.

The crashes are an annoyance but not enough to make me spend 200 quid on a new one, so I'm just wondering if the graphics card is indeed the (only) problem (I listed three different problems and as I said above, I am not sure if they are all related) and if there is anything that could help other than buying a replacement.
