Buchul computer blue screen or black screen, blue screen says it is NV4 DISP problem, now I can t ge

Friend, the reason for the computer blue screen is very complicated, and it is a conflict between the software! [Refer to Article 3]!

1。If this is an accident, usually restart the computer and the symptoms will disappear!

2。Incomplete anti-virus (use anti-virus software, full scan and custom scan)!

3。Software conflicts, incompatibilities: redundant similar software installation, (360 Butler, software uninstall, find uninstall, again:

4。The computer system has stubborn viruses and Trojan horses or worms interfere with, or the system files have been lost (360 system emergency.

Rescue box or Kingsoft first aid kit, Kingsoft net shield, etc., any of them, full killing, and then: system repair).

6。There are new vulnerabilities waiting to be installed in the system (patched for high-risk and important, others are set to: ignore).

7。Graphics card or memory CPU, or fan is in poor contact and loose or has dust covered, (unplug the eraser) Note is: Desktop!

8。The memory CPU is overheated, and the heat dissipation is not good! (Don't turn on for too long, turn off and dissipate).

9。There is a bad comment plug-in on the computer! (Scan it out, clean it up immediately).

11。If it still doesn't work, the system files are missing! Or maybe there's a serious error in the system memory!

12。Reboot the computer, after the computer brand is out, press F8, enter the safe mode, the last correct configuration, press enter, press enter, try!

13。Playing games on the blue screen, generally the system does not support this game! (Change game version).

15。If it still doesn't work, you need to "one-click restore" the system or "reinstall the system"!

Change the system, if it doesn't work, change the graphics card & memory.

1、There must be a problem with the graphics card,One is that your graphics card driver is not installed (no driver or don't know how to get down,Upper driver home**Driver elf,After installation**search**,The address is another is that there is a problem with the graphics card hardware,First see if the graphics card is connected to the power cord of the motherboard,If so, it is connected,Unplug the graphics card,Wipe the gold finger with a clean cloth,Then plug it back in,Is the fan stuck, Whether the capacitor on the graphics card has leakage and other phenomena, etc.

2. It is recommended to install the original operating system disk (use the system disk of the garden, and install the original version manually), do not use the ghost system, mainly because the original installation does not integrate so many universal drivers.

If there is a problem with the graphics card, the motherboard will alarm (provided that there is no problem with your motherboard jumper, and there is an alarm sound when the computer is turned on normally).

If it has been determined that the graphics card is broken, then replace it with a normal graphics card and see if it can run normally.

It's a problem with your system or a problem with the graphics card driver

Take a look at how well the CPU cooling power supply works

Redo the system and see

Reinstall the system, I've been in such a situation too, just reinstall it.
