Computer shuts off and turns back on suddenly
This has happened to me a few times already. The first time was in February. Then it happened yesterday. Today it happened again. The symptoms are always the same.
The computer would suddenly shut off without warning. The power light would go out completely, but then it would turn itself back on. The computer would make a weird noise. Hard to explain. It's like it's trying to run something. But it's not the usual "whirrrrr" sound I typically hear when it's busy. I wish I could explain it better.
Looking at the Event Logs, I noticed this for each of the 3 times it blacked out like this:
ACPI thermal zone ACPI\ThermalZone\THRM has been enumerated.
_PSV = 323K
_TC1 = 4
_TC2 = 3
_TSP = 6000ms
_AC0 = 323K
_AC1 = 0K
_AC2 = 0K
_AC3 = 0K
_AC4 = 0K
_AC5 = 0K
_AC6 = 0K
_AC7 = 0K
_AC8 = 0K
_AC9 = 0K
_CRT = 393K
_HOT = 0K
_PSL - see event data.
Could this be an overheating issue? Or maybe a power supply issue?
