So I booted up the PC with the old E6400 Processer (Like I mentioned). I downloaded the Flash File and the ASUS Update Utility.
I flashed the BIOS in Windows, and restarted. I immediately got a 'CMOS Checksum' failure. I restarted again, and did not get the error.
So the second time I booted, it took me to windows. I checked the latest BIOS in windows (start>run>winmsd) It showed the BIOS as being a version from 8/2008 - which I assumed was the version I installed. It was definitely newer than the original BIOS version, which Ive never updated.
Regardless, I turned off the PC, shut it down and opened it up. I reinstalled the new processor, new Heatsink, graphics card, RAM, and reconnected everything.
I put it all back together, and went to start the PC again.
Same exact problem. PC Starts up, no POST beep, no signal from monitor.
Im 99% sure if I put the old E6400 processor back in, without making any changes, that the PC will boot right up. I am going to try this right now. Atleast that way I will know for sure if the processor is causing all of this.
My suspicion is that I either:
A.) Didn't Flash the BIOS properly (which is likely, I've never done it before)
B.) The E8500 Processor is defective.
Like I said, Im going to put the E6400 back in and see if it boots. Ill post back in a few min.
