Need assistance badly. Built many, but have never had an issue like this (Specs below). Thank you in advance for your response.
Issue
All POSTS have progressed exactly the same: Initial power up, all fans kick on, All LEDs kick on, I get three beeps with the third beep interrupted, then the system goes into constant beep mode. The system never gets to video.
Process
Upon first POST failure, I contacted Gigabyte about the beep codes. According to Gigabyte the beep codes are meaningless (Award BIOS). Followed their instructions of unhooking everything except the power supply and CPU. Received the same beep code. Again, according to GB, the problem was either the MB or CPU. Replaced the MB and had the same problem. Replaced the CPU and had the same problem (now new MB and CPU). Just tonight, replaced the PSU and am still getting the same problem. I've connected video to both the on-board and video card with all configurations.
New system, all new components:
CPU: AMD 64 X2 4600+ (65W)
Motherboard: Gigabyte GA-M61P-S3
RAM: CORSAIR XMS2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 675 (PC2 5400)
PSU: Rosewill RD400-2-DB ATX V2.2 400W Power Supply
HD: Seagate Barracuda 7200.10 ST3500630AS 500GB
Video: MSI NX8500GT-TD256EH GeForce 8500GT 256MB
Case: COOLER MASTER Centurion 5 CAC-T05-UW
