I've been experiencing random crashes for a little while, especially running games.
Error: (01/03/2020 07:09:09 PM) (Source: Microsoft-Windows-Kernel-Power) (User: )
Description: 4
It was suggested it may be a PSU fault. However the bios reports the psu voltages as 3.3, 5 and 12 all within spec.
Now I see my mobo BIOS reports the cpu voltage as 0.98V which seems very low.
COuld it be a faulty regulator or cap on the mobo - and if so is it economically repairable?
 
What PSU and how old is it?

Could always pop in a new CMOS battery (CR2032 lithium coin) as part of maintenance on old boards.

What CPU voltage is it supposed to be? i.e. When you set a manual Vcore and save and exit, how much is the difference?
 
the Microsoft-Windows-Kernel-Power error just means the system rebooted unexpectedly, unfortunatly it doesnt does tell you what caused it, what is your system spec and are you overclocking?
 
Cpu is normal at 0.9v when idle,it'll jump to around 1.2 to 1.35v when stressed

Random crashes could be an unstable overclock or memory related

You need to list your pc specs
 
Thanks for all your help; I discovered if I set the cpu voltage as fixed at 1.2V the pc was more stable; I didnt know it would drop on idle,and my feeling was it was dropping a little too much at times.
The PSU in question was a 530W Hiper HPU-4M530 V2 SLi Ready B - which I've now replaced with a Corsair VS450. Glad to know the ASUS P8Z77-V LX2 mobo is OK.
The BIOS has had me puzzled - until I discovered it does not report a drive as present unless it contains a boot sector!
And Danny - while working on it I took your advice and replaced the BIOS battery!
 
Turned out the mobo WAS faulty; ran mprime in linux for 24h straight, same with memtest86+; then would not even show bios screen at startup; just flaky.
At seven years old not realistic to repair or replace it so the whole lot has gone - i5 3600, 8G RAM and the mobo.
 
Mobo might have well died because of that Hiper explosive torturing it.
Don't think there was any single good part in those PSUs and ripple and voltage regulation might have been far out of spec.
