Hi,
I have recently put together a second PC for guests to use. For the motherboard, I used an ASUS Z97-A board that I got used a couple of weeks ago. I put an i3 on the board and it worked perfectly outside the case, turning it on using the on board power button. However, today when I put the board in a case, it didn't power on, no fans spun, but all LEDs lit up. No display either. It can't be the CPU socket, as I haven't removed the i3 since I first installed it. I have tried removing the CMOS battery for 10 mins and reseating it, but nothing happened. I even swapped out the memory but still no power. I wasn't careless with the board, leaving it on an anti-static mat while I waited for a case. I am using a Corsair CX550 power supply that I know for a fact works. I am thinking that I might have flicked a switch I wasn't meant to or something, I rarely get to use these higher end boards and don't know what 90% of the switches do.

The total specs are:
Intel Core i3-4130 @ 3.40GHz
ASUS Z97-A
Corsair CX550
Radeon HD 7850
Hitachi DeskStar 500GB HDD
1x8GB SPECTEK 1600MHz
TITAN CPU Cooler with MX-2 Thermal Paste
Cheap Used PCSpecialist Case

Any help would be appreciated,
Thanks,
Daniel

Try testing with case fans disconnected. Make sure that you've correctly installed the standoffs between case and motherboard.
I have tried booting the PC with as little extra components installed, including fans being disconnected. I tried the motherboard in an NZXT case recently, with standoffs installed (the other case has those lump things instead) and there was no diffenence.
Thanks for your response anyway

If disconnecting the 8 pin CPU power cable, connecting a case fan and starting the board, does the case fan spin?
I tried that, but with no luck. I'm going to try reading the manual to see the default positions of the switches on the motherboard. I might have enabled or disabled something important.
