Hi, I bought and installed an Athlon 64 3800+ X2 to my computer a couple of days ago to replace my 3500+. The motherboard is Asus A8V-E SE, and it says everywhere including the manual that it supports dual cores.
Well, when I press the power button, it powers on, but there is no display and the CPU fan just spins full speed and the hard drives sound like they're not doing any work. My case speaker caught on fire for some strange reason many years ago and I pulled it out so I don't know if it's supposed to be making beeps. I figured it might not be displaying anything because my previous CPU was already overclocked a bit so I took out the battery (then put it back in) and used the reset CMOS jumpers too, but the problem stayed. I unplugged all hard drives, DVD burners, PCI devices, USB devices, still nothing. I reseated my 7800GT, and made sure the 6-pin connector was in it. I even got a new power supply. This has got me completely stumped. Any ideas before I attempt to reseat the CPU?
