Computer power failure problem, suspected graphics card problem, please help me point out the troubl

It is possible that a certain component is aging, and once it overheats, it will cause a short circuit, and from your description, it can be inferred that it is related to the graphics card, or maybe the graphics card itself is aging. So, you can change a good graphics card first and try if there is no problem.

The best way is to find a friend's computer to do a replacement accessory exclusion test, which should generally be a problem with the power supply or motherboard. Otherwise, you can only take it to a computer company for testing, and it is estimated that it will cost about 50 yuan to unpack the test.

It's not the graphics card or the power supply problem, let's talk about the graphics card first, clean up the heat sink of the graphics card, and see if the graphics card overheats because of poor heat dissipation, the heat of the 460 is very amazing; Then there is the power supply, which may be due to the aging of the original over time, resulting in insufficient power supply.

My friend clearly told you that my computer is in the same situation as you, and it will be turned off like a power outage after a while! Power supply problem, it's not good to buy a power supply, you find me, I'm responsible!

Said a whole bunch of nonsense. Dismantled the board and repaired it, if you guess correctly, it should be a problem with the capacitor.

This is either a system problem or a hardware problem, it is recommended that you change to a 350W power supply to try. I guess it's a matter of the power supply.

ProcessorAMD Phenom II X4 955 quad-core.

Motherboard: GIGABYTE GA-870A-UD3 (ATI RX780 RX790(AMD 770 870) chipset).

Memory: 4 GB (Apacer DDR3

High temperature will only restart and will not lose power.

It does have an impact.

If the system display screen is stuck after booting, or it takes a long time to enter the system, then it is possible that after the power failure, it has caused some damage to the hard disk (there should be no damage to the power supply, otherwise I am afraid that it will not even be able to turn on the boot), once the hard disk has a physical bad sector or the logical partition is confused, there will be a situation like the good situation you see, and the reinstallation system will naturally have problems.

In this case, it is necessary to use a PE system such as a system rescue CD or a system rescue USB flash drive to format or rescue the data information in the hard disk. Because it is impossible to accurately judge the extent of damage to the hard disk, it can only mean that if the disc can be accessed with PE maintenance system, then quickly copy the important information in the hard disk, once the hard disk really has bad sectors, then it is almost impossible to completely repair, and it is only a matter of time before it is scrapped.
