System Specs:

• Gigabyte B760 Gaming X DDR4 (rev 1.0)
• i7 14700k/4070 Super/32gb corsair vengeance
• Windows 11 64 bit

Problem:
Switched from Windows 10 to Windows 11 and now experiencing system-wide crashes and instability. Apps randomly crash with error codes like:

• -2147483645 (0x80000003)
• -1073741819 (0xC0000005 — access violation)

Everything was completely stable on Windows 10 — no crashes at all.

What I've tried:

• Clean installed all chipset drivers from Gigabyte (Intel INF, Management Engine, LAN, Audio)
• Disabled Memory Integrity / Core Isolation
• Disabled GPU hardware acceleration
• Tried both old and new GPU drivers
• Changed UAC settings
• SFC scan
• Multiple different driver versions

Nothing has fixed it. System was rock solid on Windows 10. Considering going back to Windows 10 LTSC.

Has anyone else had system-wide instability after switching to Windows 11 on a B760 board? Any suggestions before I give up on Win 11?
