BIOS resets after complete power off

[rayanbaydoun234]

Hello everyone!
I recently replaced my old corsair cx 750 with a thermaltake toughpower 750M psu. Being new to modular psu’s i installed the motherbaord 24 pin cable incorrectly from the psu side , connecting only 1 of 2 plugs that should be in the psu.
After 2 failed atempts to start my pc (psu was on but the motherboard wouldnt turn on) i realized my mistake and rectified it. Now the pc works normally except that the BIOS resets after completley shutting down my pc and disconnecting it from power (detaching psu power cable from power outlet).
Edit: to describe its behaviour , after booting from a complete power off (having no electrical power), the pc turns on then off , then on again with reset bios.
If i shut down and keep power alive , this doesnt happen.

replace your CMOS battery

Change your computer's CMOS battery. Its on the motherboard somewhere. It looks like a watch battery.

I can't find the Toughpower 750M on their website...

http://www.thermaltake.com/psu.aspx

Can you confirm from that site which one you have.

 

[gdmaclew]

I agree. Change the battery.

If the pc worked properly before, I find it unlikely that the cr2032 battery should fail after the psu change.
It is cheap to replace the battery, but they usually last a large number of years.


Why did you change out your corsair 750w psu for another one of equal capacity?


Were you having a problem with it?

@bajgur,@ehmkec i will try that as soon as i can
@gdmclew the site is http://www.thermaltake.com/products-model.aspx?id=C_00002989
@geofelt i was trying to solve an earier issue about poor performance with the gtx 970, thought since the psu has coil whine while gaming , it could be the cause

So it was a Toughpower Grand Series. That's why I could not find it.
