I recently purchased a refurbished Dell Optiplex 9020. I replaced the CPU and Lithium battery immediately and booted the computer. After a week it refused to turn on. I tried different things like switching the rams, switching the power cord, etc. Sometimes I get the red light on the power button and other times the fans just turn on really fast. I can not seem to get this to work after watching multiple videos. Can anyone help?
What's the exact description of the Intel processor(CPU) it came with?

The Dell OptiPlex 9020 comes in 3 case sizes (mini tower, small form factor, ultra small form factor).
Which one do you have?
What's the exact 7-character service tag number on it?
