The current card has a VGA, a DVI, and what looks to be either a DP or HDMI port. I'm thinking that since the RADEON HD 4650 is no-longer supported by drivers from AMD, I should probably find a replacement (not from AMD?) for the video card that DOES have driver support for Windows 10. Therefore, I'm thinking the video card/driver may be at fault.

Very thorough anti-malware scans have been performed and lots of junk removed, but still, an occasional freeze. The PC freezes occasionally - for reasons that have not as yet been determined. The OS is Windows 10 Pro Version 1809, Build 17763.379. (The reason for this configuration is obscure.) A DELL Optiplex MT 990 equipped with a RADEON HD 4650 Video Card seems to be unsupported by Windows 10 compatible drivers.
