[SOLVED] CPU voltage too high. how can i decrease it?

[magirator]

Hello. I had some troubles with my pc for last 3-4 month. It was turning off by itself, i gave to the service and they told me that my psu is too old, they adviced me to buy a new psu. After i changed it the problem still remains. It turns off by itself and sometimes in bios in right bottom part i see voltages in red colour. today i first time saw high cpu voltage. it went up to 1.77. now its about 1.5. is there a way i can decrease it? i have no idea how to do it through the bios.

may it be because of the problems with electricity at home?

Are there any 'one click oveclock presets' applied in your BIOS?

Remove BIOS battery, clear CMOS, apply defaults, set back up XMP profile for RAM, and see what voltages seem selected/applied in BIOS...

Now check WIndows and HWMonitor for voltage indications...

If high (above 1.27V or so) , look for possible BIOS offset options...
