I know how to flash BIOS, etc. The problem is that when the other person flashed the BIOS it had the screen turn black while writing the new file. Now when you try to power it up it just sits there and does nothing or will do the standard 7 beeps of death. I have tried the various "tricks" about overheating the system with a comforter/towel, removed the CMOS battery, etc and nothing is working. The smallest USB drive I have is a 32GB, it was formatted as FAT32 and and wouldn't work in any USB port with the various key combinations people have said to try.
