intro me best price/performance SSD under 700, 120GB and above pls.

Crucial M4 cause random BSOD in a few days time period, anyone facing this problem?

No, I not blaming the SSD. Just want to find out what the cause, normally, before i had SSD, I left my PC at night for downloading and still well the next day.
But, after upgrading to M4, I continue my routine and the next day, sometime, very rarely, my PC would restart or BSOD.
So far, I havent been able to see the BSOD cause everytime it crashed, it auto restard back to Window Login on the next day.
Finally today, it crash the first time when Im using the PC, but, Im scared what will happen, so, I just restart my PC before it got to BSOD.
Having using PC for so long, I havent encounter much BSOD, so I got scared

I have flash the lasted firmware, 000F.

Clean install, but I do have 1 partitions containing all my games installation, reformat did corrupt some of my games but most is still able to run without a problem.
I did copy all of my save file from My Documents from last HDD.
