My pc keeps giving me blue screens

[MegaMasterMike01]

Since I built my pc I keep getting blue screen probably once a day and some of them say. “Irql not less or equal” and “pfn list corrupt” and “critical structure corruption” and what I thought was the issue was my ram witch didn’t work in slot 4 and I tried another stick in that slot and it did not work ether so the slot and stick are bad so I did not use them and now I can not use my pc for like 1 hour without it blue screening what’s going on? And I tried reinstalling windows to windows 7 thinking it could be a corrupted windows and could be windows 10 but that did not help. Pc specs

how sure are you about your OC being stable? maybe turn it down to stock settings.
