Which computer expert will help me, and the computer master will help me

Disassemble the main chassis, remove the graphics card and memory module, plug it back in, and try to turn it on again.

Try a few more times, it should be that the contact between the gold finger is poor, and you can use an eraser to gently wipe the gold finger there. (Unless you're out of luck and your graphics card or memory module is broken.) ）

Regardless of whether the hard disk is started or not, as long as the problem of poor contact is solved, you will know whether the hard disk is good, in fact, it is very simple, touch the hard disk when you turn it on, as long as the hard disk is slightly moving, the hard disk is started.

CMOS discharge is meaningless and has nothing to do with not being able to turn on. Discharge means removing the coin cell battery from the motherboard for a few minutes and then putting it back on.

Check your graphics card to see if it's in bad contact. If there is no problem, just see if your memory is plugged in properly. Is there the above phenomenon after pressing the host switch?,I mean there's no alarm sound on the top.,Or there's a diagnostic card on the motherboard.,On the display.,There's always a phenomenon to analyze what the cause is! ）

You didn't make it clear. The monitor has no signal, is it because the host is not turned on After turning on the power, press the switch between the host and the monitor, is there a beeping short alarm sound According to your supplement, it can definitely be concluded that it is a contact problem. Remove the memory and wipe the gold finger, if it doesn't work, then remove the graphics card and wipe it, I've also encountered it.

Maybe the power supply or capacitor is burned... Then clean the computer completely.

If it doesn't work, go to the computer city to repair.

Confirm that the cable connection is correct and the cables are good, and then look at the boot symptoms, the host only the CPU fan turns and then there is no response, you can unplug the memory to listen to whether there is an alarm sound, if there is a CMOS discharge try. If not, it should be the CPU or the power supply is broken, and the possibility of the power supply being bad is higher The other thing is to confirm that there is no problem with the monitor.

Check if the indicator light of the computer host is moving, and whether the hard disk is flashing?

Is the monitor plug falling off? If the two screws are not screwed on, it may fall, if it falls off, it is the same as the phenomenon you said, and the main machine is working normally at this time.

If the hard disk indicator light is not on, if you have the ability to do it, it is recommended to remove the hardware one by one, leaving only the graphics card, memory, and CPU to boot and see the effect.

See if the wires behind the monitor are all connected!

Two possibilities, the first system is broken. Second, the computer's hard drive is broken.

The console is turned on? If the host can be lit, it means that the connection cable between the monitor and the host is not in good contact.

Laptops are normal! And the configuration is poor! Don't think about it, you can't help it!

The CPU is too bad, the current design computer, the core is above, the graphics card has to be a professional design graphics card, and the minimum has to be a professional entry graphics card.

EDIUS has not been used, but I have used it often and then use PR, PR memory occupies a lot of memory, and editing software eats CPU

Your system is not installed well, you shouldn't install those ghost systems, and your computer should also be fully scanned for viruses with free big spiders, which are stronger than domestic rogue antivirus. Also check if your SSD 4K alignment is not and the BIOS is turned on for AHCI not.

Taskbar Right-click Start Task Manager Look at the process inside When you don't open any software, see which CPU and memory occupation is relatively high, you can take a screenshot to help you see Maybe there are too many software in the background when you boot up, or it may be a virus.

The computer is aging.

It's low-profile in itself.

It's still like this after restarting, and it's generally okay to operate like this.

In fact, this problem is very simple, you can fix it next 360 security guard.
