I have a gigabyte UDR5 with 12GB Ram, and i7 920. The os runs of 2 x 80GB x25 SSDs in raid0 (mobo software raid) and I have 4 x 320GB raid5 for storage (2 year old drives). Running windows 7 Ultimate x64
In the last 2 or 3 weeks my PC started freezing randomly, recently every 20 minutes or so. The screen freezes, yet I can still move the mouse, but all the windows are frozen. I tested the RAM, unplugged everything except the keyboard + monitors... nothing helped.
I unplugged the drives I have in raid5... and the freezing stopped. I then deleted the array, and left the drives as separate disks, all are visible in windows.... and I had no freezing problems. Remade the RAID5 array.... it was stable for 2 days, and then the problems started once more. Deleted the array, everything is normal again.
Im inclined towards the drives being bad, but then why do they work fine when not raided?
My OS array, on the same mobo, works flawlessly.... so Im confused.
