Hey all, I am fairly new but have been lurking for about a month. I have: Mobo: SN85G4 Proc: Athlon 64 3000 RAM: 512 PC2700 Geil Vid: GeForce FX 5600 256 MB HDD: Maxtor Diamond Max 40 GB Other: Toshiba DVD-RW/+RW My problem is this, after running perfectly for a week the system won't boot properly. Upon powering the PC the system will post on screen and then the hdd light flashes and then...nothing. The bios will correctly identify the CPU, RAM, and all drives. My monitor has a green light so it is receiving a signal. I have tried the following. 1) Swapping four different hdds to see if it was the hdd, with the above result. 2) No hdd, with the result of HDD Failure. 3) Booting from CD-Rom, with the same above result..Nada. If anyone has any advice/ remedies I would appreciate it. Thanks in advance. The Noob.
