Correct inspection and repair steps for black screen after computer screen

Yesterday, my friend said that after his desktop computer turned on, he went into the splash screen, flashed a blue screen and then became a black screen and died there. Usually we encounter the situation of blue screen more, blue screen when there are errors prompted to see the wrong hint can find the problem, but this time the more special blue screen flash and have not had a chance to see the wrong hint on the black. Here are the steps I've analyzed.

1, first ask a friend the reason, is under what circumstances appear, is to do what operation or, the computer fell and so on. He said he downloaded things, the computer turned on for 2 consecutive days, and came back to look like this. Preliminary estimate is not something burned out, but it is not possible, desktop computer for 88 days will not be a problem. A step-by-step check is started below.

2, the first thing is to be sure that the motherboard, power supply, CPU, memory these four things are not bad, if these four things have a bad boot can not open, now to be able to enter the system, but to Windows to start the screen problems.

3. Press F8 to open "Advanced startup Options", select "Last Known Good Configuration" press ENTER. This step is to check that the user has not set any wrong parameters themselves, causing the system to not enter.

4, after the selection and found the same situation before, can not enter the system, the same is the first blue screen and then darkened screen. Next we reboot, or boot press F8, this time we choose "Safe Mode" press ENTER. This step is to check whether the user has updated the driving level, what software is installed, system files are damaged by viruses, etc. If it can be started, it is described above, at this point you need to remove the software in Safe mode.

5, the choice of Safe mode found, or the same as before the blue screen and then darkened screen. This shows that the system must be broken, may be infected by the virus, deleted the system files, causing the system can not start. Next we reinstall the system. installation system using a U disk or CD-ROM can be. The process of installing the system is not omitted in this section.

6, but when I started from the system disk, the following screen, Windows loading file progress bar to go to the end of the black screen, what the picture is not, the system and automatically restart, has been so dead cycle.

7, this is strange, the system is not installed. Next check the hardware issue. This machine installs the independent video card, pulls off the independent video card. Displays the integrated display card that is VGA to the motherboard. This step is to check whether it is a stand-alone video card problem.

8, unplug the independent video card after found the problem remains. Say obviously the card is good. Next look at the hardware, excluding the above four hard drives, as well as the independent video card, the rest of the hard drive. Think of the hard drive can not be bad, only bought less than one months, but also authentic, Seagate's hard drive. No matter what kind of test.

Replace the hard drive to the desktop test or remove the hard drive to the mobile hard drive box test, I use the second method, remove the hard drive and put it on the mobile hard drive box test. I removed the hard drive and put it on the hard drive box and found that the hard drive was not read. The result is clearly that the hard drive is broken.

9, think Impassability also useless, a few days of hard disk is so bad.

To add, you can also use the PE system disk to boot into the system, this method can quickly find the problem. The ability to enter the system indicates that there is no problem except the hard drive. After entering the system to see if there is no hard disk in My computer, if there is no hard drive will indicate that the hard drive is broken. It's very simple.

Note: Hard drive bad friends do not own toss, hair factory repair can be. If you build a problem, the factory is not to repair.
