Hi guys, Bit of a problem here. I've got an older PC I use sort of as a server, specs are as below: Asus H87I-PLUS Pentium G3220 4GB G.Skill RAM Using onboard graphics since I rarely need to actually plug it into a screen. Picked up a i3 4170 on the cheap, needed a bit of extra grunt for CCTV connected to it etc. Replaced CPU, turned it on, fans all speed up, power light on case turns on - then nothing. Nothing on screen, no 'thinking' light - just nothing. Reinstalled G3220, booted OK, updated BIOS version to latest (which apparently added support for this CPU), reinstalled 4170 and still nothing. Cleared CMOS using jumper, tried again - same thing. Tried the G3220 again, works fine. Have also tried removing RAM with no improvement. Am I missing something obvious? Or is the CPU DOA? Thanks for any thoughts/suggestions!
