Gpu code 43 on boot need help

[ProfessorX]

Hello, Im a new member of the forum but first I gotta say that I love your comunity !

 

Ive been having some trouble lately with my gpu, here is my full system specs :

 

Cpu : amd fx-8350

Mobo: Asus m5a99x evo

Memory : 2 G crucial 1866 mghz

               4 G  mushkin redline 1866 mghz (I know its not recommended but its been working fine since 2012)

PSU : coolermaster rs-550-pcar-e3  http://www.coolermaster.com/powersupply/extreme/extreme-power-plus-550w/

GPU : Zotac GTX 770 amp edition.

1 SSD

3 HDD

OS: Windows 10 Education

 

I have been having random problem with my peripherals since I upgraded to this gpu, I wasnt sure exactly what was wrong.

Lately it got worse as I was doing an update on Windows. The screen started being laggy for half a second before the

lock screen appear while booting Sometimes even with artefact. Everytime this happens, There is a code 43 error on the gtx and i have to go uninstall the driver, search for plug and play components and windows automaticaly reinstall the driver and voila, the card is working very well, I can even game on it.

 

When the problems began I also changed the setup of my fans and plugged them directly on the mobo in the CHA_FAN ports.

I have narrowed the problem to either the psu fails to supply enough amp to the gpu, or one of the compatibilty updates of windows 10 is causing

the problem alone. The Gpu has a minimum of 600 watt and 44 amp on 12v rail, so i bought a 750 watt with 64 amp on the 12v rail, just to

be comfortable to expand more if I want to.

The gpu has been working fine for a few months already so I dont know what triggered the problem.
Do you think my current psu could be the issue ?

The other problems I had were hard drive related, somethings the drive would crash while im on the computer and when I restart,

the only way to get it back to show in the bios is to unplug the sata cable on the mobo and change ports. Then it almost always come back online.

I will receive my new psu in a few days and I will keep you updated.
Thanks for your help,
