PC power cycles repeatedly on and off.
PC power cycles repeatedly on and off.
Hello, i need help identifying the problem.
I have PC that will turn on for about 3 secs and then turn off, then about 3 secs later turn on again before turn off again. The cycle will continue until i cut off the electricity.
There is no beep at all, no display, no BIOS, all the CPU and other fans are on, there is only one light from Mobo, which indicated that it have power (it's on).
Before this the PC is fine, never turned off abruptly or crash (at least i can not remember the last time it crashed).
I have tried clean the PC, made sure all the cables plugged correctly, clear and change to new CMOS battery, place 1 RAM in every slot.
Specs:
- Asus p8Z77-M (LGA 1155)
- Intel i5-3570
- Corsair Vengeance 2 x 4 GB DDR3
- Radeon 5670
- PSU Dazumba 600W
I have one other PC, tried it and can still run, so i test the VGA and HDD in there and it's fine. Sadly it is an even older PC (20 years with lots of uses and still running quite fine although sometimes it crashes) with LGA 775 and DDR2 RAM, so i can't test the RAM or CPU in there.
I removed all other cables except the 24 pin, 8 pin, all the fans and front panel. I remove all RAM and the problem is still the same. Based on my searching if PC turned on without RAM it will either not power on at all and make beeping sound or it will turn on fine, but no display. With that, can i remove the RAM as the possible problem? If yes, then the problem is either Mobo, CPU, or PSU then.
Is it possible to know the exact problem? I'm short of money, so i can't really buy something just to test. The other thing i can test is changing PSU from the older PC, but i'd like that to be the last option. I'm scared if the newer PC still does not work after changing PSU, somehow the old PC will not work after the PSU put there again.
Can someone help tell me what step i can do to know the exact problem? Any help will be very appreciated. Thank you.
Welcome to the forums, newcomer!
PSU Dazumba 600W
This seems like a device that doesn’t quite fit the description of a proper PSU. I think I’d borrow a solid 550W unit from someone nearby or ask for help and see if the problem continues.
Can we pinpoint the exact issue?
Fixing problems usually involves checking one thing at a time, following a list of steps. If you bought a component thinking it was the cause, you might end up assembling a PC meant for troubleshooting instead. That’s why we recommend getting parts from friends or neighbors.
Moved this thread from the Components section to the Systems section.
Based on your situation, could you remove the possibility of RAM being the issue? Would it be wise to try other solutions first before replacing the PSU, to determine if the motherboard or CPU is the cause? Thank you! Please note I cannot ask for a PSU from anyone.
Hello, thank you for reaching out. I've switched to a different PSU, the Xigmatek 650W, and it's functioning properly. However, the problem remains. Could you kindly advise what steps to take next?
