Hi everyone I really need your help to solve my problem. Today while I was working my laptop made some soft noises and after that it just hanged. I pressed down the power button to shut down the laptop. Then when I restart I run into the same problem with in 5 minute again had to shut down the laptop by pressing down the power button. Infact in the last hour I had almost done this 5 or 6 time. Every time the laptop makes some noise and then it hangs. I suspected a hard drive failure so run the seagate software sea tool for windows, which passed both S.M.A.R.T check and short drive self test. Also I run into 2 BSOD during this process (the minidump folder is empty) and after the laptop restart I get a black screen with the massage “ No bootable device, insert boot disk and press any key” so again I pressed the power button to shut it down. So what is the problem? Please help me to solve this problem I am totally unable to use the laptop more than 10 – 15 minute at the moment.
