clock_watchdog_timeout Error?

[HeyLookItsRed]

I've got a Pentium g3258 and I was playing tf2, and I needed to open another program, so I opened tekkit and my computer crashed. So I restarted my pc and booted back into windows. I started up Tf2 and relaunched tekkit and the same blue screen opened, and it said something about clock_watchdog_timeout. So when I rebooted I went into the BIOS and underclocked my pentium g3258 from 4.5ghz @ 1.39v   to   4.2ghz on the Automatic Voltage ( What it had been on before since I built this PC ). I went into google and just searched "clock_watchdog_timeout" but couldn't really find anything, but I saw the words " Deadlocked CPU", and I do not know what this mean, can anyone help?, Thanks, any response will be greatly appreciated.

Your overclock isn't stable. clock_watchdog_timeout is always an overclocking issue.

Yes that BSOD is CPU related. Normally means the CPU has locked up due to unstable OC/ Not enough volts. This is essentially what it is  'A watchdog timer (WDT) is a hardware timer that automatically generates a system reset if the main program neglects to periodically service it. It is often used to automatically reset an embedded device that hangs because of a software or hardware fault.'
