Computer shutsdown after post beep
This one is for any hardware gurus....
This is not strictly a Linux issue, however, here goes.
I just rebuilt my system to the following
AMD Athlon 64 3200+ Socket939
Innovision GeForce 6600GT PCI Express
Seagate Sata 120GB
Lite On DVD Combo Drive
3 X 512MB Kingmax DDR400 PC3200 Ram
iCute 0408SL Case with 500W iCute PSU (18A on 12V Rail)
fdd unknown brand
This is my fourth rebuild and the first time I have had an issue. What happens is the following:
Connect power, red light on Motherboard comes on, hit power button and the system powers up, All case fans start running, CPU Fan starts running, Northbridge fan and GPU fan all start running, green power led comes on, all looks good. Get what sounds like the successful POST beep then system shuts down to only the red light on the motherboard.
So, started by disconnecting all drives and two of the Ram sticks and trying again. Same result. Disconnected all case accessories Front Panel audio, usb and Firewire, and case fans. Tried again, same result. Tried different power supply (400W PSU) same result. Removed Graphics card and reseated, same result. Removed memory and reseated, same result. Tried other memory same result. Removed memory altogether and got the standard continuous beeps from POST, indicating no Memory. This was good, not a Memory issue. Removed the case reset switch, HLED, PLED and speaker. No beep but still shutdown. Reconnected speaker. Removed Graphics card and still the same result.
OK, I haven't removed the CPU as I couldn't take it off without removing the heatsink and fan assembly. Also, I haven't tried different Graphics cards or Motherboard as I don't have spares (not S939 or PCIX GPUs) but I am going to try and arrange to check these on the weekend.
I have had all these components operational before just not in this configuration. They are all compatible as the only really new things are one Memory stick, the PSU and Case, all the rest of it comprised my last machine (with some other bits and pieces). The case and Power supply are powering the machine I am writing this thread on.
If any one has any ideas I would greatly appreciate them.
