I believed we had already got most information on the CPU, but here goes. inxi -C CPU: Topology: Dual Core model: Intel Pentium Dual E2200 bits: 64 type: MCP L2 cache: 1024 KiB Speed: 1300 MHz min/max: 1200/2200 MHz Core speeds (MHz): 1: 1791 2: 2098
Clearly it's a 64 bit: https://ark.intel.com/content/www/us/en/ark/products/33925/intel-pentium-processor-e2200-1m-cache-2-20-ghz-800-mhz-fsb.html
Have you tried clearing CMOS, or upgrading BIOS? There is such a thing as BIOS corruption, which clearing might help. Rather than a quick clear, I'd take the 2032 battery out overnight with the PS unplugged, then do the jumper clear after putting the battery back in
That CPU will work in a lot of newer motherboards that would provide a graphics upgrade from 950 to something better. If looking, try for a G41 or G45 chipset board. Lesser chipsets better than 945G include 965G, G31 & G33. Some G41 boards use DDR3 or DDR3+DDR2 RAM, while all earlier Socket LGA775 are DDR2. If you are using a PCIe graphics card, then P models instead of G would also suffice.
