Ok, you see where I bolded that text in your post, please tell me what exactly was installed.
If you need some help, start startup recovery with windows vista or 7 and wait for it to load, go to menu where you can boot off of system restore.
It will show you what was installed during your windows session and each reboot the driver or software needed when granted before there was no more recovery points.
It could be hardware driver conflict or it could be incompatible software or etc.
If it BSOD of you, pay close attention to it and be ready to jot it down so that we can back trace it and find out whats going on for you.
NOTE: also go right back into bios and look under your AHCI settings and make sure your ssd drive isn't set to IDE mode but sata ahci mode.
That should resolve some problems and allow your ssd to stay online for good.
