When installing Windows 7 on SSD, install will complete and computer restart. It will then log in to windows and be fine for ~10 seconds before force logging off and restarting. From there is will constantly loop without going into POST, stopping at the A2 debug code (Enable IDE).
Have tried with/without GPU and both ramsticks, changed positions of ramsticks (all work), have used different sata ports for both ssd and bd drive, have updated BIOS, cleared cmos, tried installing W7 a few times, unplugged all irrelevant parts and retrying.
No other ideas. If you can test with a HDD, you would know if it's a controller issue or not.
Try also a different SATA cable for the SSD.
Have you used the Windows DVD before? It might be corrupted - resulting a faulty installation.
