Yesterday I decided to go out and pick up this MSI Radeon 5450 from CL since my onboard GFX on the slimline started going (was displaying a blue-ish tint on my screen). I do alot of research have some friends help me and out of all the ones available out there this seemed to be best since the Slimline PSU is terrible..160W PSU. I get home I pop it in, fits perfectly I'm really excited to try this out and I boot into Windows...Card is not in device manager? I start going crazy now researching what could be wrong and it led me to a dead end. I thought it was the BIOS I did research and they only had a bios update .exe for windows vista so I couldnt update. I went into the bios and set the primary video to PCI-E. Still nothing. I was really going crazy at this point. I decided to change the Primary Video to PCI. WOW! It worked! I was really excited at this point. I go in, I install the catalyst drivers everything is great. I played Diablo 3 for a few hours just to see if it would even run and stress the card a bit. GREAT! I went to sleep woke up and turned the PC to see how blessed I am. No output video again and not being recognized. I then proceeded to extract the .rom file from the .exe bios update and flashed it using ASUS Award Bios Utility via DOS. That didn't change a thing. I do get video on from the onboard vga. Im not sure as to where to troubleshoot now as it was working. Any help would be great! Thanks!
