I know the voltages are right, because when connected to another motherboard
the voltages show the specified +15 +3.3 +5 volts values.
I do have a problem with the file system and other errors continuously
occurring.
Chkdsk reports repetitive errors in the file system, file index, etc.
I know that can come from a defective hard drive or memory.
But S.M.A.R.T and software tests don't report any problem.
As for the memory, quite extensive tests with memtest did not
find any errors.
I use Windows Scheduler and the following .cmd script to
fix the files errors every two hours
:start
echo.
echo DISQUE C
echo.
call chkdsk c:
if not errorlevel 3 goto end else goto start
:end
Works well.
Still, I will keep looking for the source of the problem.
