I have 3 hard drives (primary master, secondary master & slave on
ATA100) plus 2 opticals (masters on IDE 1 & 2). Single 512MB stick of
DDR2100.
I used to have 3 opticals (DVD-ROM, CD-RW, DVD-RW).
I have removed the DVD-ROM & CD-RW and replaced it with a second
DVD-RW.
Since I did this the system system has become incredibly unstable.
Writing to the new DVD drive sometimes works, sometimes it freezes.
Ok, I can live with that - just one of those things, though very
frustrating in time, money and coasters.
But it also freezes randomly just when copying data from one hard
drive to another, and now regularly freezes with a black screen on
first boot, working ok on the second. It didn't use to.
I've tried every combination of BIOS settings I can, including the
default ones in the manual.
My question is - can anyone recommend the most stable configuration
for the mobo settings (trp, DRAM timing...)? I don't much care about
the fastest speed - the odd fraction of a second increase is pointless
if I'm wasting minutes constantly rebooting.
Thanks,
DAH
