Faulty SATA controller?

[besomuk]

Hello everyone...I have problem with hard drive and / or mother board.

At some point Windows 7 started to act weird - lockups, Explorer crashes on right click, random restarts, etc...

I decided to reinstall everything and notices that SATA HDD is sometimes recognized, and sometimes not. BIOS sometimes report SMART error - sometimes not. Sometimes, i can get into USB diagnostic tool ( Data Lifeguard Diagnostic ), sometimes not....

I tried to change cables, ports - always the same.

I also tested memory - it's ok.

I also tried same HDD on another machine with same cables - everything works, no SMART errors, everything is OK...

So...Is it time for new motherboard?

It could also be caused by PSU, but that is not very likely. Surely the next thing to check is motherboard.
