So I'm absolutely stumped here. My PC had been working for about almost a year, and then suddenly it isn't booting up. I have had some sporadic power cycling issues in the past, but this was solved by powering off the power supply, then powering it back on. But now this is different.
Motherboard lights up when connected to the power supply, but when I try to turn it on, it will start to power up VERY briefly (think less than a second) and the power off. (This happened out of the blue - I hadn't made any hardware changes.) It happens so fast that there isn't time for the mobo to have a code readout. I've tried everything I can think of, and can't isolate the problem.
- I've tried pressure testing ram 1 stick at a time, one pair at a time, and tried with no ram.
- tried graphics cards individually (I'm running sli)
- tried removing all the ram and both graphics cards
- I figured the mobo had crapped out so I RMA'd it. Got the new mobo, reassembled everything, and I'm having the same problem. This obviously involved reseating the cpu and cooler.
- then I figured it had to be the power supply. Got a new power supply and .... wait for it, same thing. tried it first with the old power supply cable, then when that didn't work, I rewired everything with the new power supply cables.
I'm really stumped here. It's strange that it's powering down so fast and with no error code on the mobo, I'm fresh out of ideas.
Has anyone experienced anything like this before? Any ideas would be very much appreciated as I'm out of options here.
My build is:
- Asus rampage v extreme - x99 chipset (replacement was new - not refurb)
- i7 5820k (no overclock)
- corsair h80 liquid cooling system
- 16gb gskill ripsaw 3000mhz ddr4 ram
- 2x 980 gtx in sli (light overclock)
- EVGA 1000w power supply (originally), now using a corsair h1000i 1000w power supply (replacement is new)
- 2 samsung 850evo ssd's in raid 0, and 2 tb WD black hdd
- case is a silverstone Temjin tj11
