There are a *lot* of possibilities for what is causing this problem. The fact that you did a fresh install with Windows 8.1 points back to this being a hardware issue. When BSODs are also happening, it often means a memory issue. Fact is, tearing down your system to ship off the motherboard and then building it back up *can* result in damage, no matter how careful you are. I would suggest that you try testing with the board out of the chassis using the minimum possible hardware. Try using a different memory DIMM or, if you don't have access to any, try testing with only a single DIMM installed. If this proves to not have any issues, install the other DIMM, by itself, and then test for issues again. If this too is OK, try testing with both DIMMs. If this causes problems, we can then think about the motherboard having an issue and whether another replacement is necessary. You are a ways from knowing that this is the case, however...
Yeah but i've ran windows memory diagnostics and memtest+ nothing shows up..it doesn't detect any hardware issues...instead of going through this much trouble i think i'd rather take my HDD out and try to install windows from another PC.. if i can install windows like that then its definitely a hardware issue like you suggested.
spearson I've actually found out the problem! thankfully it was just the HDD error! i replaced it in another PC and it still gave the same error and then i ran windows error checking in windows explorer and it fixed it for me..
I can't believe this WORKED! i've tried running the same CHKDSK from command prompt and windows recovery console and i still got the error but when i did scan from windows explorer somehow it fixed the error!
