I know questions like this were asked a few times here, I read everything I could find on google and here but my situation seems to be a little bit more different, the problem doesn't seem to be caused by the psu.
This week, I switched from this build,
-asus m5a78lm-lx motherboard
- amd phenom II x4 processor
- asus hd7850 graphics card
- corsair vs450 psu
- kingston 4gb 1333mhz ram
to
-asus h81m-k motherboard
-intel i7 4790k processor (I use the default heatsink that came with the cpu)
-asus hd7850 graphics card (same)
-corsair vs450 psu (same)
-??? 4gb 1333mhz ram *the hardware guy who gave me this says it is h-value but I don't really believe it, there's no sign of a brand on it. I exchanged the old ram, motherboard and cpu with the new ram and h81 mb*
Whenever I boot the pc in the mornings or 40-50 minutes after a shutdown, it fails to get things working at once, first there's a tiny sound, and in 1 sec, it resets. does this for a few times, then it starts making a louder kind of a sound (some fans start working) and it resets like 2 times. after this warm up routine it starts booting. After the boot there's no sign of any problem, I played witcher 3 and wow for a few hours, there were no problems at all. And if I shutdown and boot the pc after 0-20 minutes, then it'll boot smoothly.
compared to my older build, something I noticed was that the cpu fan doesn't start immediately after it starts booting (smoothly). It delays for a few seconds (2-3) I thought it was a uefi thing but I'm still not sure if it's normal.
I updated the bios. I had to do it in order to install an operating system otherwise the windows installer wouldn't boot. It took me quite a while to figure that out but the update didn't fix the cold boot problem.
I plugged out the graphics card and tried switching the PSU with my backup 300W psu, the same problem continued. I also tried switching the reset and power buttons.
I think it looks like there's something wrong with the motherboard but then why does the pc run so well after the boot...Is the motherboard incompatible with i7 4790k? Can a bad ram cause all this?
