Mobo issue?

[r1bby]

Morning all,
I have a MSI K9AG Neo-2 Digital mobo and am having troubles with it (at least I think this is the culprit)
I was wondering if I could ask on your opinions before buying a new mobo as MSI haven't a clue.

When I connect my hard drive via IDE it works fine,
when I connect my hard drive via SATA it crashes the PC randomly,
I've tried multiple mint distributions (& XP),
I've tried multiple HDD's,
I've tried multiple SATA cables (straight with no kinks in the cable),
yet it still seems to crash randomly,
I can almost make it happen 100% when I stream media off the internet,
(my guess would be that it's using the HDD's RAM to stream and is falling at the SATA connection)
it usually crashes by the scroll and caps lock lights flashing on the keyboard,
or the whole thing freezing except the mouse movement,
or a crash and restart back to the logging on screen
(in XP it's usually a complete crash and reload from POST)
I think it must be the mobo as I think I've ruled out everything else (or have I?)

hardware:

AMD Dual Core AM2 5000+ BLACK CPU (OC'd 3.2ghz)
MSI K9AG Neo2 Digital Mobo
4GB DDR2 800mhz RAM

Hitachi 250gb 16mb 7200rpm HDD
Hitachi 160gb 16mb 7200rpm HDD
2x Western Digital 40gb 8mb 7200rpm HDD

The same disk? (there are disks with both IDE and SATA connections I think)

(my guess would be that it's using the HDD's RAM to stream and is falling at the SATA connection)

No way - a complete misunderstanding - but it is used to cache what's to be written to the disk, but it can keep up and if it does not you only get lost data in this case
Don't quote me on this but it seems a bit like faulty hardware not least as you have very similar problems in XP and Linux

Ah I've been using an adapter to convert an IDE HDD to SATA,
I have both SATA only & IDE converted HDD and neither work 100% via SATA connection,
I borrowed a friends PC the other day and linked my main HDD into his mobo
with my SATA lead and it didn't crash so I guess it is my mobo
If I use my IDE HDD via IDE then it doesn't crash so it can't be RAM or the CPU,
it must be the SATA connection, I've also tried all 4 SATA sockets and have the same result.

So I guess I'll be buying a new mobo sometime soon...

Sad but true - be careful with important data for the time being

Closer to the answer was the sata to ide converter plus my AMD 5000+ Black CPU being overclocked, the HDD just didn't like it,
I have lowered the overclocking to the standard speed and am using a standard sata HDD and this issue has been resolved.

Well - sad but true - I presume you are not overclocking when you ask for help
The very first thing to do if you overclock and get problems - no matter what - is to stop overclocking
