Hello everyone, im new here. I got a hardware issue and maybe you can help me out a bit.
I upgraded from a h110 m-ATX and i7 6700 to a Z170 ATX (asus maximus VIII ranger) and an i9 9900KF. I had to modify the BIOS to achieve that. My gpu is a 1070 ti and regarding RAM im running 8+4 @ 2133 (awaiting new RAM currently). The PSU in my PC is at least 6 years old and is 600W, CoolBox is the model i think.
The problem is that when i managed to successfully set everything up, i powered on the PC with everything plugged and it turned on for like 0,2 s and shut down afterwards (fans try to spin, gpu LEDs do flash). When that happens, im forced to switch OFF and ON the PSU and then i can try to power it ON again (or i can press CLEAR CMOS instead). Then i unplugged the 8 pin connector of the gpu and PC posted but telling me to fully power on the gpu. So after shutting down i did that and it booted and everything went well, to the point i tested it rebooting like 5 times(shut down, then power on, even powering off PSU) and everything neat; tested bf1 with 120 fps cap : gpu was at 70%, so i uncapped but for a very short period, maybe 5 min but indeed gpu reached 99% of usage providing ~160 fps. I made sure my gtx wasnt loose anywhere on PCI slot and screwed it nicely. Ok so that was yesterday.
Today after i came from work i tried to start the PC and guess what : the same issue as described above : shutdown after 0.2 s. (Note : im writing this post on this very PC so i actually managed to boot it again). So i started experimenting (hadnt replaced gpu/psu yet to see if they work but assuming i was able to play bf1 and gpu frametime was around 4 i can tell gpu isnt broken), i laid the PC down horizontally so made sure nothing could move or be in a bad position while troubleshooting. OK so i began with classic retrying after switching PSU OFF and ON few times : Nothing. Then i unplugged all additional fans (they are like 4) and left GPU 8 pin connector plugged and then power on PC. It failed, i powered off and on PSU, tried again : it booted successfully. PC OFF, I grabbed and shaked the GPU quite a bit to see if its some short on the PCIe or the card is loose, but it booted just fine again after that. PC OFF again and connected back all the fans. Booted fine again.
I have to say pc was able to run idle all the night (yes thats only idle) and i hadnt experienced yet any hangs or BSOD or sudden power off, but it's day 2 after the upgrade so things might happen. Also, my motherboard is missing one O402 capacitor somewhere near the SuperI/O chip. Well, if that is the issue, i could solder it back again just grabbing another O402 from a trash PCB or so. I flashed the BIOS using CH341A so i doubt it is a faulty BIOS, MAYBE it isnt modded well by me by choosing wrong settings but i doubt it (used Coffee Time). May it be the PSU? NOTE : MY PSU doesnt come with 8 pin connector but with a 6 one, but i have an adapter from 6 to 8, that isnt any issue, right? Should i run prime or some other stressing PC software that could involve both CPU and GPU high usage to see if my PSU is actually faulty (if that software exists)? Thank you in advance.
