Various PC issues possibly linked to MoBo

[DestroKek]

Hello bit of a longer post because there is background to it,

Yesterday after cleaning my PC from inside with compressed air can (cpu cooler and fans) I have started to expirience various issues.

At first my monitor didn't register any signal coming from the PC nor did the other monitor/tv recognize it.After bit of search I found out that taking out and putting back in the battery or CMOS as people reffer to it does the trick and it did so PC booted as per usual.

After it booted I opened HWMonitor and task manager to check is everything in order and unfortunately for me my VCore voltage despite being set to 1.235V in Bios was 1.36V,my RAM worked at 1600MHz despite being set to 1866MHZ and it started working in single channel mode instead of dual channel (2x8GB sticks).Furthermore in task manager I could see it saying DDR3 16GB but utilizes only 8 and doesnt allow it to go beyond 8GB usage.

Doing anything in Bios doesn't transfer to windows aside from AHCI disk mode

CPU Load line is disabled,voltage control is set to manual with values within tolerable rates.

Any help is valuable and appreciated!

Specs:
CPU:AMD FX 8350 4.0 GHZ
GPU:MSI R9 390 8GB
RAM:Corsair Vengeance 1600MHz 16GB DDR3
MoBo:AsRock extreme 3 970 r2.0
PSU:Cooler Master 750W 80 Bronze plus

As you know, removing the battery reset all BIOS values to stock. The fact that getting your PC to boot after just doing a cleaning with canned air by resetting the BIOS indicates that BIOS setting were somehow corrupted. When you say that BIOS settings are not transferring to Windows, does that mean you have gone back into BIOS and lowered VCore again, changed memory profile, etc, etc and when you get to Windows those changes have not manifested? If you reboot and go back to BIOS are the values the changed values or are they back to factory? This is what it kind of sounds like, your BIOS setting are not saving.

Can this be fixed? [strike] If it is a physical fault (something has come loose) then it might be possible to solder it back to down ... if you can find the spot. If it is instead damage to EEPROM (the chip that has you BIOS on it) then flashing a new BIOS might fix it (or kill the MB). All in all, a fix is possible, but unlikely.[/strike]


***** EDIT **** I was just checking your MB user manual and it still uses a CLRCMOS jumper (this is less common today). If you blew that jumper off, then BIOS setting will not save. Look near your SATA ports and you should see pins labeled "CLRCMOS1". There should be a jumper between pins 1 and 2 with pin 3 uncovered.

Yes I have went back into BIOS and changed everything back to what it was.The values remain in my BIOS no matter how much I reboot but don't manifest.I can still see the jumper and it seems firmly attached.I was able to fix the memory issue by putting my ram sticks into A2B1 combo instead of A2 B2 or A1 B1 combo.

So another thing I am noticing RN after swapping the RAM combo is that my small CPU overclock test (4.1GHz) that I made to see would it manifest before doing the RAM thing is now actually working and my voltage has gone down from 1.36V to 1.25-1.27V (I set it to 1.25 manually) Idle:0.8-1.25V Under load:1.26-1.272V

Very very strange. You can try to flash the BIOS, but I can't promise that won't kill your MB.

Edit **** Since you are back to pretty close to where you want to be, I might not mess with it any more. Is dual channel memory working?
