Let me start off by saying that this computer has been sitting untouched for about a year due to a damaged processor. So today I bought a new processor and installed it but now I have a new issue: no display on the monitor. The motherboard has an AM2 socket and the processor I put in is a AMD Athlon II x4 640 quad core 3.0GHz (socket AM3). But from what I read, the AMD's are backwards compatible and this specific model should defiantly work with the AM2 socket. So this is why I'm almost positive that the new processor isn't the issue. I've looked online and tried other peoples suggestions which include: switching around the RAM, removing CD-ROMs, the HDD, replacing the CMOS battery, and using a new power supply.
I've also tried multpiple combinations of monitors/tvs & cables. For example, HDMI over DVI, VGA over DVI, VGA. I've tried with and without the NVIDIA graphics card that I installed some years back. The only thing I can think of now is downgrading the motherboard to an older spare I have lying around.
By the way, everything else appears to be working normally. The LEDs are on, fans spinning. Just no display
CPU fan is spinning and so is the fan on the graphics card. Also, there's no beeping.
Any suggestions/advice would be greatly appreciated, thanks.
