PC Suddenly refusing to boot

[K3nny3]

The other night I shut down my PC how I normaly would but in the morning It refused to boot and I still cant get it to do anything. What happens is after pressing the power button the fans spin up for about 30 seconds but there is no post code then shuts itself off It then spins up the fans for about 5 seconds then shuts off again. Finally it spins up the fans and makes a normal post code but then powers off. Pressing the bios key takes me to the gigabyte logo but then it powers off again. Taking out the memory and booting the pc makes a post code for no memory which made me think the memory was defective but after getting a replacement it still did the same thing. I have tried another PSU and it has not helped and I checked every connector to no avail.

1. make sure all the power cables are plugged in

 

2. reset cmos.

 

3. reseat CPU

 

report back if all 3 things fail

 

then i'd suggest trying to boot to a windows recovery usb and running the repair tool, which actually works sometimes

Have done all those things to no avail, I would try boot into the windows recovery usb but I cant get to the boot menu

I agree with 1 and 2, but I say reseat RAM and use 1 stick at a time before messing with the CPU.

it could be an issue with the power supply, or something is overheating really quickly. make sure everything us plugged in like the CPU fan and what not

I had a similar issue, and it turned out to be the motherboard shorting on the back of the tray.

 

Try making sure the wiring in the back isn't forcing the tray into the mobo or try removing the motherboard and running it off of a box.

I tried another PSU and got the same thing and cooling hasnt been an issue before,

as for reseating the memory, I have tried it and even went as far as to get some more but the only time I could get somthing else to happen was when I took the memory out all together
