BSOD + random freezing - Windows 7 Ultimate (mostly ntoskrnl.exe)

I have been experiencing quite a few BSOD's and freezes over the past week or so, at first I passed it off as a once off until it became more frequent (both BSOD and freezes)
I'm not sure if it would have anything to do with it but it started a few days after I started hosting a terraria server for myself and one friend; i recently (about 3 days ago) stopped hosting terraria, and began hosting starmade

just today I clean installed windows 7 and updated all of my drivers through "Computer>Manage>Device Manager" and still got another 6-7 BSOD's (some of which weren't in the minidump folder)
I might add that the blue screens tend to occur more while i am playing games (terraria/starmade) and the freezes occur during start-up, shortly after start-up, but rarely more than 10-15 mins after start-up.
my computer would also get into a routine where it would begin starting up (i would hear the fan turn on) but the screen would remain blank and it would automatically shut-down, and restart on its own. i would usually try to break this by turning off at the power point and waiting a short while, it would sometimes work, sometimes not

i don't know much at all, but by looking at the .dmp files most of them appear to be caused by ntoskrnl.exe

i have attached .dmp files from before and after the clean install

Any help or feedback would be greatly appreciated
