The computer doesn t start properly, sometimes it can start, sometimes it can t! Urgent!

This is a common problem encountered in the daily hardware maintenance of the machine, there is no problem with your software, there is a problem with the hardware, the most likely is that you touch the hardware when you sweep the dust, it is a hardware that has poor contact or hardware damage.

Solution: Unplug the memory, graphics card, carefully check their slots, whether there are foreign objects, dust, small particles, etc., and clean the slots. Carefully wipe the plug part of the memory and graphics card with toilet paper.

Plug them in when you're done wiping. Try it on. At this point, the problem has been solved.

If it still appears.

Unplug all peripherals except memory, graphics card and CPU, including monitors, keyboards, mice, etc., it is a light chassis, plug in the power supply and turn it on, see if there will be an alarm, if there is no alarm, shut down, fork other peripherals one by one, and turn on each one until you find out the problem hardware, (here there is a greater possibility of problems with the keyboard, I have encountered such problems caused by the keyboard 3 times).

You can also detach the motherboard battery and press it again after a few minutes to let the motherboard power down. It is also possible to solve the problem.

Personally, I feel that there is a problem with the graphics card, which has caused the above situation. You can borrow a graphics card and try it out to see if these problems still occur.

It feels like your graphics card might be caused by something that is broken.

There are many reasons for this! (1) The system has jumped up; To reinstall the system, (2) hardware problems will also occur, (3) poisoning may also occur; You can take it and test it in time.

Check it out first and start with the hardware problem. The hardware fan is not rotating normally. CPUs and graphics cards. If it's all normal, you just take the parts of the machine off and clean it up.

If the problem with the software is solved, reinstalling the system will solve the problem.

I'm going to say very simply, the problem with your graphics card. Didn't run. You take it to the test.

Is the hardware overheating? Such as CPU fans, chipsets, etc.

Reinstall the system, and if it doesn't work, go to the repair point for maintenance.

Memory, motherboard, and power supply are the three most likely to have problems, so check them out.

Ninety percent of the problems in the computer are caused by software, the most effective way to encounter the problem is to reinstall the system, use the ghost version of the cloning system, reinstall the system for more than ten minutes is enough, it is recommended to reinstall the system to try, and reinstall the system to know whether there is a problem with the software or hardware, let people make a backup for you when you do the system, if there is another situation, you can restore the system with one click.

Problems with the motherboard.

Really last time a friend asked me to help him look at the machine.

And that's sometimes the case.

His safe mode can be entered, you can see if yours can not.

I don't want to look at the above.,Let's talk about the simple reason.,If your computer hasn't replaced the memory or anything recently.,I think there's something wrong with your system.。

Whether there is a problem with the system, you can detect it yourself, whether your computer is poisoned. Whether your previous computer was working properly. If it's not normal, it means it's slow, or if there's something else that you haven't had before.

Eliminate system problems, that's your hardware problem, according to the phenomenon you said, I speculate that there is a problem with your memory (in the case that your hardware has not been replaced) and your computer has a blue screen, you have to pay attention to see what it is**, go to the Internet to check, you can also know what is the problem.

In addition, I suggest that if none of the above situations occur, you can reinstall the system and try it.

Generally, when there is a problem with the computer, the order of inspection is software first, then hardware.

The hard disk is set to the first boot.

Partition table repair.

Reboot or reinstall if that's the case.
