Thanks - you were right about the PSU. Motherboard all fine :-)]]> Sun, 11 Dec 2016 23:21:30 +0000 https://forum.asrock.com/forum_posts.asp?TID=3880&PID=20513&title=z87-pro3-wont-start-when-warm#20513 <![CDATA[Z87 Pro3 wont start when warm : Xaltar wrote:My first question...]]> https://forum.asrock.com/forum_posts.asp?TID=3880&PID=19665&title=z87-pro3-wont-start-when-warm#19665 Author: wardog

Generally with things like this (powering up) the PSU is the first thing to test/replace. If you have another PSU on hand I would try switching it in before we look anywhere else. PSUs lose efficiency over time and voltages droop more and more. Let us know how it goes.

I agree with Xaltar. First thing I'd do is swap in an up to the task known good PSU and see if it acts up again.

The PSU is around 3 years old]]> Sun, 27 Nov 2016 16:13:55 +0000 https://forum.asrock.com/forum_posts.asp?TID=3880&PID=19654&title=z87-pro3-wont-start-when-warm#19654 <![CDATA[Z87 Pro3 wont start when warm : My first question is how old is...]]> https://forum.asrock.com/forum_posts.asp?TID=3880&PID=19625&title=z87-pro3-wont-start-when-warm#19625 Author: Xaltar

My current setup consist of:

DVD: Samsung SH-224DB DVD-RW

HD: 1 TB Seagate Barracuda ST1000DM003

SSD: 120 GB SSD Samsung 840 EVO

Motherboard: Socket 1150 ASRock Z87 Pro3

Memory: 4x4096 MB DDR3 1866 MHz CL9 G.Skill

CPU: Intel Core I5-4670K 3.4 GHz

Graphics: ASUS AMD R9 270X 2GB DDR5

PWS: Corsair Builder Series CX600 V2 - 80 PLUS Bronze

Case: NZXT Tempest 210

OS: Win 10 64bit

Generally, the PC runs fine at stock speeds (no OC). However, when it's been shut down after use (when warm), it won't boot. When started, there is no power supply to peripherals incl signal monitor, and it goes into a loop state where where the fans turn on for 5-10 s at a time. If I leave it to rest for a couple of hours, everything is fine again. If I just reboot from Windows, without shutting down, there's no issue.

I have systematically tried to unplug the DVD, HD, RAM modules, exchange graphic card without luck. So I suspect it it either the CPU or motherboard. I bought a new CPU cooler as I thought it could be due to an overheating protection of some sort (also tried to disable it in the BIOS). CPU temp is 44 dgr C.

Any suggestions?
