Why does Acer 4736G automatically shut down when playing games under win7

If it is a laptop, it is likely that the CPU or graphics card temperature is too high, and the graphics card occupies a lot of video memory when playing games, causing overheating protection and automatic shutdown. It is recommended to take a look at the temperature. Super bunnies can also look at the temperature.

The laptop automatically shuts down, generally due to the following reasons:

1 The computer system is poisoned or infected with malware.

2 CPU Fan Bad CPU Temperature Too High, Overheating Protection.

3 The power supply is bad, or new hardware has been added, and the power supply is insufficient.

4 The graphics card or graphics card fan is broken.

5 The motherboard is broken, and the motherboard core is overheating.

Solution: 1 Check whether the antivirus software has killed the virus, you can determine whether it is caused by the computer system poisoning or malware, if there is a virus, it is recommended to use a combination of antivirus software to kill the virus, or if it doesn't work, go to the maintenance center to solve it.

2 Test the temperature of each hardware on the computer, open the case, see if the CPU fan and graphics card fan rotate normally, find out the problem, and go to the maintenance center to replace the CPU fan. Different computer models have different CPUs**, which need to be detected to know**.

3 If the computer has a discrete graphics card and the power supply is not enough, you can only go to the repair center to change to a higher power power supply.

4 Shut down, touch the south bridge, north bridge chip, graphics card chip of the motherboard with your hands, if it is very hot, it is likely that the motherboard is damaged and needs to be repaired immediately.

The causes tend to focus on incompatible hardware and drivers, problematic software, viruses, etc. Workaround:

1. The cause of the virus. Use PC Manager to disinfect the virus.

2. Reasons for memory. Use an eraser to wipe the gold finger of the memory module and wipe off the oxide layer to ensure that the memory module is installed and running normally.

3. The chassis is not clean. The CPU fan has too much dust to run normally, causing the CPU temperature to be too high, so use a brush or hair dryer to clean up the dust on the inner wall of the case, the CPU fan, the graphics card fan, and the motherboard.

This is an automatic power-off protection caused by high CPU temperature.

Your fan heatsink is clogged with dust or there is too much sludge in the fan shaft, causing the fan to perform poorly.

Ordinary cleaning dust can only clean the dust of the heat sink, for the sludge in the fan shaft must be disassembled and cleaned with pure alcohol, and then add oil. There is also a heat dissipation base that can be equipped with dozens of dollars each.

The most critical to the cooling of the laptop is the internal CPU fan, if he can't do it, the external cooling base is also in vain. External heat dissipation can only cure the symptoms, and the internal fan is the root cause. The external cooling base is only an auxiliary function, and the most important thing is the heatsink and fan of the notebook itself.

There's no way to do it, either buy that super good radiator or modify the internal heat dissipation (the laptop is not easy to get), and try to use it in an air-conditioned room.

Acer notebook heat dissipation is garbage, wait for the cold weather to play.

Could it be a problem with the graphics card?

There are many reasons for the automatic shutdown of the notebook, system problems, or poisoning, or there may be problems with the motherboard, there is a power outage, and the power supply is not available, so it automatically shuts down.

Most of the time it's because of the high temperature.

Laptop shutdown, most of them are caused by bad fan heat, but some of them are due to power adapters, batteries, and hard disks caused by automatic shutdowns.

1. There may be a problem with the settings of Baibios, enter the BIOS to restore the default settings or take out the battery of the motherboard, reverse the buckle and discharge, and wait for 5 minutes to reverse install it. DAO purpose: to restore the default value of the BIOS settings, and to exclude the automatic restart or shutdown of the BIOS's cooling presets.

2. If the computer shuts down automatically when using a certain application software, the automatic shutdown failure may be caused by this program software, and the program software can be uninstalled.

3. Then check the power supply, the power supply quality is poor, aging or the power is too small, which can not meet the power supply needs of the computer accessories, and the high-power and high-quality power supply can be replaced.

4. Then use the elimination method to check the memory, graphics card, CPU, CPU fan, motherboard, etc.

5. Check the memory, the memory quality is not up to standard, poor heat dissipation, overclocking, mixing and inserting of different brands of memory and the CAS value setting is too low, etc., which can cause the computer to shut down automatically, and the memory parameters can be adjusted accordingly in the BIOS.

6. Check the motherboard, the motherboard aging, capacitor failure or pulp, the motherboard power pins, the motherboard and the chassis backplane short circuit can cause automatic shutdown, you can take the motherboard out of the chassis to check or test, then check whether the CPU fan rotation and the CPU temperature is normal, and then check whether the bottom of the CPU fan heatsink is dry, if it is dry, clean the silicone on the CPU fan, and then recoat the good silicone. If the fan is not normal, replace the CPU fan.

7. Cleaning method: It is a method to eliminate faults by cleaning the dust of the parts in the computer host. Dust is one of the factors that can also cause computer automatic shutdown failures, dust can cause parts aging, pin oxidation, poor contact and short circuit and other failures.

For these faults caused by dust, it is generally more effective to use the cleaning method.

There are many possible reasons, first check whether the battery is normal.

If you're not playing big games or 3D graphics, I can tell you for sure that the power supply isn't broken.

I've dealt with this kind of problem much better.

Generally, automatic shutdown is a problem of CPU overheating.

There are three types of CPU overheating issues:

1: The CPU is broken. Hardly possible, exclude.

2: The CPU fan is broken, it is possible, but it is generally found. You can open the case and turn it on to see if the fan is rotating and whether the speed is normal.

3: Silicone failure between the CPU fan and the CPU. This is common, and it is easy to ignore, silica gel is a layer of gel between the CPU fan and the CPU, its thermal conductivity is good for heat transfer, if this thing fails, then the temperature of the CPU still cannot be dissipated, resulting in the CPU temperature is too high, and then triggers the CPU automatic protection system and power failure.

Hope it helps.

I suspect that when you dismantle it, you moved something, especially to check if the CPU heatsink is loose.

Dismantle it yourself, take out the fan, drop a drop of special computer fan lubricating oil, the computer city is sold, not expensive.
