I recently put together a new rig and didn't like the video card I purchased so returned it and bought a ati radeon hd 5850. Well when I installed the new card I began to run into problems. I have no keyboard support at all nor any mouse support. I have tried the p/s keyboard and got nothing... tried a usb keyboard and still nothing...
Here is my setup if it will help:
MSI 870A-G54 motherboard
AMD Phenom II x4 965 BE
4 GB Kingston DDR3 1333 MEM
ATI RADEON HD 5850
Thermaltake Duorb CPU Cooler
I figured it may be a short due to grounding issues but I took the board out and tried it with only the cpu, fan, video card, and ram yet still the same issue. I even tried replacing the new video card with one I had before i decided to upgrade and still the same issue. Did a CMOS reset and that didn't help. Funny thing though is that it will boot up all the way to windows(being I took off the halt on error feature earlier yesterday) but because of the lack of mouse and keyboard support I cant do anything with it.
Thanks for the link but I've gone through the list several times and still haven't been able to figure this thing out. I forgot to mention though that the last message says during the post something about keyboard/interface error. I just find it strange that it will run windows but its like my input drivers are non existent. I can't even enter the bios prior to booting windows. Also I'm running windows 7 64 bit. Oh and one other thing that may be a key factor. The last time that I was able to use my system correctly I hibernated it which had probably something to do with it. After this the next time I turned it on was after I installed the new video card.
