I am upgrading a machine that I first built a couple of years ago. I
bought a new A7N8X-VM/400 motherboard, an Athlon XP 2800+ (Barton)
processor and 512 MB of Crucial PC 2700 memory for the upgrade. The
previous mobo died, due to swollen and leaking caps, the 3rd Soltek SL
75DRV4 I've had to replace because of bad caps. (I'm not alone there,
I know.)
I assembled the system, plugged it in, and the CPU fan spun about a
half turn when power was first applied to the power supply (When I
turned on the power strip). The machine will not power up after that.
The power LED is lit.
I have disassembled this machine a piece at a time to the point that I
finally tried it with the bare motherboard laying (isolated) on my
bench with only a remote power switch, the memory installed, a known
good hard drive, a known good monitor, keyboard and mouse plugged in
to it, with the same results. Unplugging even the hard drive, mouse,
keyboard and monitor makes no difference. I have tried two different
power supplies, both of which are tested good, one of which is brand
new. The new one is a Fortron FSP350-60GN supply and the used one is a
Super flower TT350. Both are rated at 350 Watts and are listed for
this processor and provide more than 1A to the +5VSB output pin, as
per the ASUS manual.
Any thoughts or suggestions will be appreciated.
