Computer problems! (Suspected to be hardware problems)

A few days ago the computer suddenly appeared in:
first:before the start is “drop” and then out into the hardware detection system, landing on the table for a long time now the boot is not sound.Only to see the lights flash drive and then you read that Hard to write a few lights flash on such a cycle flash back and forth (about 1-2 minutes continued) during the period without any sound, and a display.
II:2, 3 minutes after the “drop” started out the hard trade mark (The hard drive is full-screen logo, before normal circumstances, the emergence of boot) and then on a black screen and then “drop” is to repeat this loud.(Repeat about five or six times) and then a full-screen emergence of a hard disk After the logo shows the self-report (used to start after the emergence of the hard disk is the symbol of this chart).
Third:Since I installed the GOST restore it after this is the choice into which, by default into Windows, and then there will be The first two possibilities:1.A black screen appears a prompt:the lack of C:/ WINDOWS/SYSTEM32/NTOSKRNL.EXE file repair solved the problem.I generally on a restart!
2.Is to enter the scroll bar WINDOWS , After the end of the scroll bar to a blue-screen error WINDOS interface (the interface, but probably occur less than 0.1 seconds on the flash off so I did not see the re-emergence of what), and then restart the computer automatically!
Both could add up to about five or six times a repeat it!
Above all, and so the process of going through, and then finally there is a scroll bar WINDOWS After the successful launch of a computer!
Beg their errant , And younger brother to take a look at the reasons for better? Software reason can not be estimated.No signs of poisoning, after a successful start everything will be all right! I am Kaba Jia's 360! First 50 minutes to give the problem or put forward any good suggestions to help me solve the problem Or to find the problem of catching 50! Thank you, the!
