This is my first time posting on Bleeping Computer. I usually am able to fix the problem I have by just reading posts other people have solved, but I am stumped on this one, any help would be appreciated. Because this is my first time posting, and I have been working on this problem for a while (sleep deprivation) I apologize in advance for any mistakes in my post. Also, everything I know about computers is self taught. I know just enough to make bigger mistakes then an average user The Problem

:The Bios was always gave an error that the cpu fan wasn't spinning despite the fact that it was, but the computer ran fine so I ignored it. My Solutions
: 1. Because I could hear the hard drive spinning after the black screen I knew his computer was not locking up. He had recently had a bout with a virus and suspected that he never really got rid of it. I've read about virus and malware corrupting video drivers so I decided to try that first. I put his hard drive in my machine and scanned with malware bytes, avast in safe mode, and finally hijack this. I found several viruses and malware on his computer, and some malicous BHO. I removed all of these. However once the hard drive was in his machine again, the problem was the same.
2. I installed my hard drive into his machine to see if windows did a black screen after the loading screen and it did.
3. I put my video card in his machine to see if it's a video card issue, and his screen went blank after initial bios screen. Up until this point I could get the motherboard to post, now it no longer does.
Should I just buy another motherboard and write this off?
