Ok guys I am new here. I got my old PC, I want to use it for old games under Win XP. Nostalgia intensifies. AMD Athlon 2200 1.8Ghz. The problem is that, the system shows the CPU like 1500+ at 1.3Ghz. I already flashed the bios of the motherboard gigabyte ga-7n400 - l, but nothing changed. I know I know it is pretty ancient but its buggin me a lot. I can play the retro games on everything but solving the problem is also important for me.
