The power supply seems to be working - cpu and case fan are working, CD and HD are getting power. Also, the only extra component I had was my video card which i removed for testing. Even tried testing w/o HD and swapped my 2 RAM DIMMMs in one by one - all to no avail. I inspected the mobo and it doesn't look damaged at all. Even took it out of case and reinstalled it - no difference. Finally, I have also switched the jumpers around to clear CMOS.
It feels like the mobo or perhaps the CPU are blown. Any help will be greatly appreciated to further diagnose the problem so that I can fix it or buy the right part. In so much pain w/o my daily dose of CSS...
Mobo: Chaintech 7NJL6 Socket A 400FSB
CPU: AMD Athlon XP 3000+ 400FSB
RAM: 2 PC3200 512MB DIMMs (Samsung)
