First crashing and now BSOD (DPC_WATCHDOG_VIOLATION)?
well damn...check/scan all your drives, check you SATA/IDE interface/drivers, try updating/reinstalling chipset/ssd drivers.
What Is DPC Watchdog Violation Error?
DPC Watchdog Violation (error code: DPC_Watchdog_Violation) is a common issue in the Windows operating system.
It’s occurred due to some specific reasons, like unsupported SSD firmware, old SSD driver version,
hardware incompatibility issues, or system files are corrupted.
This is not modpack issue...you have issue with your OS/Hardware.
