"Dead" core in task manager

post #1 of 41
Thread Starter 
This has me stumped. Windows task manager shows core #1 (with the first one being #0) totally dead. Zero activity. have a look:



I have LCDSirReal on my G15 as well, and it shows that core's activity spiking, CPU usage says something stupid like 262% or -80% or 24.-5% and so on.

CPU-Z is reporting four cores, and if I run, say, IBT, the core comes good and gets some activity. As soon as I stop IBT, it goes dead in task manager again.

I do have CNC enabled.

What the hell is this?

Possible problem with Taskmanager? Use SpeedFan or AIDA64 and see if there is any CPU usage on that core.

It's a sign of the computer apocalypse.
Try to see if core temp gives you the same reading.

It could be corrupted files? try "sfc /scannow" in cmdpromt.

Or your CPU is degraded? try some more voltage?

Motherboard degraded?

Faulty BIOS? Reflash with update?

Lol broken. try a reinstall of windows on another drive or something to be sure its not a driver problem, try other monitoring programs... but yea.. maybe your core is dead?

Check your CPU "drivers" under Device Manager?
Once again...

I scan my HDD's every week, did it yesterday, all fine. As for degradation, I doubt it, this chip as not been over 60c, or gone over 1.5v for that matter. More volts wouldn't help with degradation I think. Though I was doing some "suicide" runs but failed to even get into windows, didn't want to push the voltage any more. Mobo is less than 3 months old. BIOS is on the latest version, too. First thing I did when I got the board.

Will do.

EDIT: Device manager says...



And as far as I know, it was working when I booted up, first thing I do is open HWMonitor and task manager

I guess I'll try rebooting for starters.
