New build won't post (solved now)

Hi

Not new to building and never yet had a problem but there is always a first time for everything.

I had a spare Asus H310 board, 16GB ram and gtx960 so picked up 2nd hand I5-8500, fitted everything pressed power button and not much happened, fans spinning, no any lights on keyboard, no signal to monitor from on board graphics or gtx960. Things I have tried:

Removed GPU - still same
Clear Cmos via removing battery as this had different cpu before- still same
tried single ddr4 - still same
Tested older CPU/MOBO/RAM to rule out PSU

I double checked every single connector nothing stands out. Hmm I'm running out of options been honest, what would you suggest, I have another 8th gen CPU but is running in another machine so don't won't to pull this out until I'm 100% sure I checked everything possible.

Thanks in advance

There's a jumper on your board I think to reset cmos, but if you are getting no fan spin up, you have both mobo power cables connected and you've checked the psu is fine, then it leaves just the mobo or the cpu that is the issue.

Fans are spinning, wouldn't the bios reset after leaving the battery out for a min?

Not always sometimes the clear cmos jumper is the better option whilst removing the battery and unplugging the psu for 5 mins.

Will give this a go tomorrow, failing that will fit the cpu to my mobo to see what I get.

Found some info from motherboard manual, now interesting part is in bottom of that description is if the above method don't work remove the battery then short 2 pins

Ok just tried the CPU in my motherboard and when turning on msi board does recognize there is a change in CPU, I didn't bother going in to bios ect as didn't see the point, any post screen enough for me, well looks like there is something wrong with spare board

Can you update the bios without a cpu installed? It should be supported anyway, but it can't hurt to try.

OK solved it now, I tired ddr4 stick individually but only in same socket, moved the ddr4 to another socket and worked, so removed the board again to have closer look, there was some sort of build up on 2-4 pins, run a razor blade against the little pins then inserted the ram in both sockets, all working now. Happy days, sometimes just helps to take a step back then look what you have missed. Thanks for your help
