I use laptop Lenovo Y450, P7450, G210M with 2x2GB. Yesterday and today, I have total 4-5 times, right after I start windows and open My Computer, everything freeze and only mouse can run, all thing in screen like an image, cannot interact with anything. After 1-2 minutes, it show BSOD and Restart, after that, I cannot boot from my Hard Drive, it looks for Booting (maybe) in DOS for too long. I restart and check in BIOS, hard drive's still there. Reboot, all thing seem fine, but I format my USB in 20 minutes, it crashes again
Now I don't use, it's idle.
- Windows 7 Professional x64 SP1.
- Full retail version, (download from MSDN with student account).
P.S: the missing driver
are memory card reader, it showed many times before, 3-4 week ago, I don't think it causes the crash.
