Possible problem after Bios Update!

[Mitico]

Hello everyone,im new here,so forgive me if this is wrong section.

 

I updated my bios to 1.80 1 hour ago using instant flash and everything went fine untill i noticed that pc ramdomly freezes for 40/50 seconds it happend 3/4 times already in various situations.. Also,i saw that when this happens hard disk goes in 100% load but there's no noise coming from it..

My Pc specs;

 

Amd 965 BE

Asrock 970 Extreme3

Sapphire HD 7750 1 GB

Corsair 4 Gb (2x2) 1333 Mhz

Corsair Cx 600 80+ Bronze

200 Gb Hard Disk

Windows 8.1 32 Bit

 

 

My question is;this could be related to bios update or it can be for a different reason? I had this version of bios before update

Thanks for help!

That's for 1st Rev... you've the first revision, right?

On the motherboard it says "970 Extreme3 Rev. G/A 1.01"

ok, HDD with AHCI or IDE?

Its set on Ide.Its an old maxtor 6l200s0

 

*Edited*

 

What i can do? When i try to run it on AHCI it wont move from windows loading screen (i tried with aggressive link power management and other one with "Amd" something,never saw before,both enabled)
