[TLAM Strike]

I posted a while back about lock ups in full screen 3d games and video. It still keeps poping up. I think its my PSU.

These are my voltage values:
Voltage Values:
CPU Core 1.39 V
Aux 0.03 V
+3.3 V 3.33 V
+5 V 5.03 V
+12 V 11.80 V
-12 V -12.12 V
-5 V -7.61 V
+5 V Standby 4.95 V
VBAT Battery 3.22 V

I highlighted the one I'm concerned about.
