windows boot problem on ASUS Zenbook SSD and SATA HDD get switched?!

[techie313]

I just bought an ASUS Zenbook UX32A, it has an SSD 32 and SATA 500, I deleted the recovery and did a clean install of win7 on the SSD (originally win was on the SATA) and I uploaded all the drivers and did some windows updates.

Problem: the laptop will randomly shutdown once a week or every two weeks, and the boot order will get switched to the SATA. Obviously i will get an error "windows cant boot" etc. I have to manually go in bios and switch it back to the SSD.

What the fugees is going on here?

I scanned the computer with Avast and did the boot scanner, 100% clean

I just updated my bios and followed instructions from ASUS, and when i restored default settings, the default again when to the SATA drive and i couldn't boot until i switched to the SSD, How do I get my system to recognize the SSD as Default boot?
