Hey all,

I have an Asus P8z77-v lk motherboard with a 120GB Samsung SSD and a 2TB HDD attached. I use RAID settings and have windows 7 on my SSD. I built my computer about 2 years ago and have had no problems until now.

I got home today and my Desktop wouldn't boot. I was getting a BSOD with Stop: 0x7e and an issue with iastor.sys. I did some research and it said that the .sys issue is normally related to the RAID controller. I tried booting then in AHCI and in IDE but it didnt work either and I was getting BSOD with 0x7B. I switched back to RAID and now my SSD is not being recognized by the motherboard. I tried it in multiple SATA ports and with two different SATA cables.

Do you think the SSD went bad? Any help on this would be great as I have run out of ideas.

Thanks!

Edit:

I downloaded a fresh version of windows on an external and tried to boot through usb with the SSD and HDD unplugged and ended with the same BSOD i started with (0x7e) and i also got something that said iasror.sys I'm beginning to think this is now a motherboard problem. Does anyone have any ideas?

Hello... 1) If you think there is a MB configuration or BIO's problem... remove the MB battery and jumper the "clear the CMOS" pins ~3min, remove jumper, re-install battery and BOOT... your CMOS will be re-created and the MB will be back to defaults and the Video output of your MB and CPU... (if you have this feature, remove the Video card for next Boot).

Windows will not LOAD a OS from a external... But you can INSTALL a OS that way... Did you try making a bootable USB stick with a Windows install ISO (or use STD install DVD) and see if that boots and allows access/communications to your SSD, (custom install mode)... when the SATA controller is set to IDE mode? (driverless mode). the "Drive Tools" app and install drive screen will...
