One of my techs went to a client today to add hardware to a HP ML350 working as a Hyper-V server. He added a new processor, extra RAM (balnaced for the new processor), and a new NIC. After he added them, the system would not boot fully. It would hang at a black screen - sometimes he would be able to see the cursor, sometimes not.
He tried to boot into Safe Mode. The server hung after loading CRCDISK.SYS.
He tried several variations of the hardware and has finally pulled all of the hardware back out. No change in behavior.
Call HP. They said it was an OS problem. Called Microsoft. They said it was a hardware problem.
Google is starting to tell me it is a virus infection and may not be related to any of the changes listed above.
Anyone have a fourth idea?
