Question

Replaced the CPU on my K7 Triton GA-7VKMP MB with VIA KM266 chipset. The new CPU is an AMD Athlon XP 2200 1.8Ghz Socket A 266FSB w256KB processor (OEM). Pin #1 golden cut edge is installed correctly. Symptom: The computer now displays black screen and keeps beeping every second or so and does not boot up.
