Motherboard: ASUS P5LD2 Deluxe
CPU installed: Pentium D 3.0 GHz (dual core)
Memory Installed: 3gb DDR2 (2x 1gb + 2x 512mb) both are 1066mhz
Video card: 512mb Nvidia 210 PCI (not PCI-E) card. I needed an s-video out because this will eventually be a media center connected to a TV that only has S-video input, so that's why i'm not using PCI-E.
-When you turn on the system, and just leave it, you'll get a quick single POST beep, and everything seems fine, but it will hang on the main splash screen.
-If you press delete right away to get into BIOS, the AMI screen pops up, and shows system info like CPU, installed memory, keyboard, mouse, hard drives, optical drives, etc. but then it just hangs on that screen and never boots into BIOS.
-There is an option to "Press F8 for BBS POPUP", but when you press F8, that changes to "Boot selection popup menu has been selected", and still hangs.
-Clearing the CMOS by removing battery and leaving for over 30 minutes (FAILED)
-Replacing the CPU with confirmed working 775 socket P4 (FAILED)
-Replaced individual, and multiple RAM modules of all capacities and brands (FAILED)
-Replaced CMOS battery completely with confirmed working one (FAILED)
-Manually cleared CMOS with jumper pins (FAILED)
-Power supply is brand new, but I tested it anyways, and it's working perfectly
The video card is obviously working or else I wouldn't be able to see that the system is hanging. Any thoughts?? PLEASE??
