Advertisements My GXCEBOT began rebooting over and over today. The "welcome screen" pops up for a few seconds, then a weird flash of light, and the "welcome screen" shows up again. This continues ad naseum. Unplugging and waiting does nothing. The hard drive is an upgraded hard drive, so I don't suspect it. I'm assuming from what I have read, that this is a power supply problem. If so, where is the best place to purchase a new (or refurbished) one? I apologize if this has been answered before and I missed it. I searched, but didn't find an exact match to my problem. Thanks.
