"First verify you have power to the power supply (PSU)." how? with a multimeter?
"You bought a "AMD Phenom II X4 945 Deneb" Did the heat sink/ fan come with the CPU (processor) That would indicate you bought a retail CPU. Even then you may have needed to remove a protective film from the heat sink prior to installing. Also, you need to install correctly." protective film from the heat sink? that's not the thermal paste?
"So, you tried booting outside the case once and it turned on for 10 seconds. Then what, did you install the board into the case at that time?" no, i didnt. the first boot and all the later attempts were always outside the case.
"From what I can see your case is not what I would have bought. First of all the PSU is mounted at the bottom, which is a bad idea, IMO. More importantly, it appears there are stamped in bosses in the case to mount the board to. This is in place of metal screw-in stand offs. That type of case can cause the board to short out to the case. You should be using insulating washers in between the case and the board with that case." yes, you know you're right
"If you have the board installed, remove it and try outside the case with only the CPU/ heat sink/fan, 1 stick of RAM, Video card, power connections from PSU to board and graphics, monitor and keyboard." i did it, nothing happened, no boot, no fan running, nothing
anyway, thanks everyone for the posts. i will buy a cheap AM3 motherboard, a cheap sempron, a thermal paste and a cheap ddr3 1066 ram stick to check what componet in my pc is working.
I know im a ULTRA ÜBER N00B, but, i think this way i can learn more, and stop being a n00b.
