I just installed a new PSU on a working system. The new PSU has more power than the one I replaced (550 W vs 520 W).
When I close the circuit to the PSU, the green LED on the Motherboard lights up. When I hit the power on button, it fires up immediately:
I hear one single beep. The cpu fan & psu fan are running, and HD indictor light turns on. I am also able to open/close the DVD drive by pressing the button on the front of it.
On the monitor, it shows the Motherboard's splashscreen, but it freezes on that screen, with the message in the lower left corner reading "Press DEL to enter setup....."
If I hold DEL, then I will still get stuck on the splashscreen, but the message will read "Entering setup....."
If I hold F8, then I will still get stuck on the splashscreen, but the message will read "Loading Boot Menu....."
I've checked all of the connectors mulitple times. I've read through these forums, tried searching for about an hour and a half, but haven't found any posts with these exact symptoms. I took out the motherboard battery for 6 minutes and moved the CMOS jumper (but should I apply power to the m-board whhile the CMOS jumper is moved?).
I've read that hearing a single beep is a good sign, that it means that memory, HD, and vid card are working properly - is this true? I checked my mohterboard manual; It tells me to refer to a table which does not exist in the manual (apparently they forgot to include it).
My motherboard is an Asus A8N-SLI.
Any suggestions on how I might be able to get into the BIOS?
