That should teach you to not buy HP (or Dell) anymore. Buy normal motherboards that are not created by companies with non-standard ideas on creating hardware.
We no longer buy brand computers but have them assembled by our specs. We do not buy support, nor do we have SLAs. We do have enough people who understand and can solve operational issues (i.e. 5). We do tend to replace more stuff that fails to work when updated or has operational issues (like network cards that freeze when under full load, that is you Dell). And we have more hot-spare machines in a second location (good for maintenance, availability on HW failure, contingency plans, ...).
