Sounds like a hardware failure.

XP on older gear usually just installs. But if the machine needs work such as cleaning the heat sinks, replacement of the heat sink compound or a failed drive, all those errors can happen.

So yes, I have but usually I fix the PC first. The errors do not tell you what to replace. HOWEVER the blinking underscore has been seen a lot when folk have things plugged into USB ports. So I always unplug USB cords and try again.
