Question Whats wrong with my computer?

[lost_in_spacs]

I was using my computer and it suddenly shut off and died. I tried to restart it but it won't restart. When i unplug the power and plug it back in and try to turn on the fan starts for a split second and the rgb lights on the fans flash and then its dead again. The power light on the mother board is on. I disconnected the psu and all the cables and re-connected them to make sure they were seated properly. I used a paper clip and tested the PSU cable which showed the power supply was working. I am getting a power cord tomorrow to see. I'm hoping its not the motherboard but trying to see if there is anything else I should be trying? The mother board is a Sabertooth X79. Not sure if I should replace the thermal paste?

EDIT: Sorry i also removed and tested each stick of ram individually
This is what it looks like when i unplug and then plug back in and hit the power button.

Welcome to the forums, newcomer!

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

Try without a discrete GPU and see if the system powers up. You can then drop the discrete GPU into your motherboard's first PCIe slot.

Reset the CMOS, pull all but one stick of RAM, and try to boot again.

What CPU, RAM, PSU and other components do you have? It will be important for further troubleshooting.

Would that be removing the GPU and trying to power the machine?

Yes

Yes

I removed the gpu still the same result where the fan and rgb come on for a split second. I moved the gpu to pcie slot 1 and nothing same result

Paperclip test doesn't prove you have a viable power supply. Only shows there is some power. That power supply is very old , most likely failing.

can you recommend a good value power supply that would work for my machine?

I used a paper clip and tested the PSU cable which showed the power supply was working. I got a different power cord and tested it, tested it in a new plug. I also tried removing the ram and putting them back in one at a time. bought a new PSU and its still giving that same lights up for a split second and then its non responsive. The motherboard is a sabertooth x79, I got a new one coming in the mail. Is there anything else I should be testing in the mean time?
