So i got an AMD 2800+ processor, very cheap, so i could upgrade from the AMD 1800+ i had until now.(on a socket A mobo - the compatibility is OK, i checked and double checked before buying) I didn't really new what were the steps to install a new proc., so i just pulled out the old one, placed the new one in, applied thermal paste and all that fun stuff, and then tried to start the PC. The thing is that nothing happened. That green light didn't flash once, the PC didn't boot. A friend of mine suggested i should pull out the mobo battery, start the PC with the new processor in and let it run for a few moments, then shut it down, place the battery back in and see if it boots. Again, nothing happened. What am i doing wrong ? Is the processor i bought faulty ? What should i try doing in order to make it work ?
