Sheapy

I bought an eGPU roughly 2 years ago that worked great with my Lenovo t410 till yesterday. The power supply blew up and I had to replace it. However afterwards, I've been getting a code 43 in the properties of the NVidia GeForce GTX 460. I've been using the latest drivers of the 460 so I never bothered downloading the setup 1.0x. Is there anything I should look for or should I just download the setup 1.0x and try using the save/load dump? The card is detected fine and it sounds like it's working during bootup, but when I reach the desktop, the fans start spinning rapidly.
