Silly twit, I got tired of you trying to shoot me down, so I snuck in wile you was away, and turned your screen around backwards.
Kidding aside, that sucks. How old of a machine is it?
Is it a local retailer, or are you going to have ship it off.
Before I would ship it off I'd at least blow out the dirt, and unplug and replug everything back in.
It may be nothing more than a loose connection. The thermal expansion inside after time, can separate a improperly plugged component from the factory.
I had new builds fail in the past, So anymore when I upgrade I keep the old one around as a server for the printer,Teamspeak, Il2 and such.
I had to fallback once in the last ten years to my old machine due to a bad mobo once, on the newest machine.
When it's time to renew again I just rotate them down, and give away the oldest.
Used to work quite well, most folks didn't have a PC or at least anything as advanced as my oldest.
But now days, I suspect due to quad cores, my old one next shuffle will be dead weight for most people interests.
Well good luck and see you on me six soon.
