PC bootlooping

(Currently not using the GTX 950, on integrated graphics which does nothing either. RAM is Transcend 2x4GB). When I attempt to power this build up, the fans spin and it's obviously powering up, but it doesn't POST or boot into BIOS, hell it shows no activity at all. Then after about a minute it dies for a couple of seconds before starting up again, and it loops this until I shut it off.

Any ideas what is causing this? Is the PSU broken? Is it because it's a Haswell Refresh CPU? Thanks

you need BIOS P1.40 minimum (just get P1.60 directly)

CPU compatibility list: https://www.asrock.com/mb/Intel/H81M-DGS%20R2.0/index.asp#CPU

BIOS download: https://www.asrock.com/mb/Intel/H81M-DGS%20R2.0/index.asp#BIOS

AsRock instant flash: https://www.asrock.com/support/BIOSIG.asp?cat=BIOS8

Don't know if you can flash it without an installed CPU

You can buy a pre-flashed BIOS chip and just exchange it with yours (no soldering, weldering needed), or go to a pc-hardware store and let them flash your chip (they have special tools for that)

What this guy said^

That's why your part lists has this warning at the top

Part List COMPATIBILITY NOTES Some Intel H81 chipset motherboards may need a BIOS update prior to using Haswell Refresh CPUs. Upgrading the BIOS may require a different CPU that is supported by older BIOS revisions.

To be able to update your bios, you need a cpu that is supported by your motherboard that you could use temporarily to flash a new bios. For example, if this is an upgrade to a previous build, sticking the old cpu in (pressuming it worked then) would allow you to boot the PC (hopefully) where you could then update the bios to support the other cpu.

Thank you for this clarification, I guess I will have to get a new BIOS chip/flash it.
