Question New PC Build: Won't boot up, red light on motherboard

JDPC · Apr 7, 2014

Just finished my build and I'm sure that I've done everything correctly. Connected every thing and tried to boot it up but nothing comes up on the monitor and there's a solid red light (CPU led) on the motherboard.

Please help!

Asus M5A97 Evo R2.0
AMD FX 6300
Corsair XMS3 2x2gb
XFX Pro 650w

Is the system even turning on? Fans moving ETC. The power button may be hooked up to the MOB wrong.

check the cpu for any bent pins or things on the socket. be sure the cpu heatsink is properly seated also make sure the heatsink fan is connected to cpu_fan slot.

Try to place your RAM sticks in different slots and check out this guide

All the fans are spinning fine. I tightened the cpu heatsink fan done correctly but the heatsink can move a bit if I try to move it.
The CPU was definitely correctly installed. I'll try moving the RAM, currently there both in Blue slots

Ahmadjon :

the ram has nothing to do with this if it did then the Dram red led would light up.

Go through and recheck all connections from supply to board and card.

4+4. < CPU power

6+2 < Graphics power

Nathan Willis · Apr 7, 2014

The heat sink should not be able to move. Make sure you have it installed right.
Check all of the jumper. Make sure the 8/4 pin CPU power connector is on right.
Check all of the connectors. Make sure the 20+4 pin connectors is installed right too.
Make sure the GPU has power. Are you getting any beeping?

I meant put 1st slot RAM stick into 3rd slot, and 3rd slot RAM stick into 1st slot!
I had boot issues in my old PC and it helped me few times!!!

Still a solid red light.
Just been looking through the motherboard manual and my RAM's part no. is not stated. It's Corsair XMS3 1600mhz 2x2gb (CMX4GX3M2A1600C9) so it should work but doesn't show up as compatible RAM in the motherboard manual. Is this the problem e.g. the red light?

Thanks

Nathan Willis · Apr 7, 2014

Yes, the is a problem. If they do not list it there is a high chance it will not work. (VERY)
Get some RAM that is compatible.

JDPC · Apr 7, 2014

Will it have damage any of the other components?

Nathan Willis · Apr 7, 2014

No, the computer will just not boot because the RAM isn't compatible.

JDPC · Apr 7, 2014

Could the manual be out of date? The RAM is ddr3, it's only 1600mhz and the timing is the same as other compatible ram.....

tiny voices · Apr 7, 2014

Nathan Willis :

This is actually 100% false. It is actually VERY hard to find RAM that is not compatible. Don't forge that there are only like 4 different manufacturers of RAM so generally they are all always compatible.

OP, your RAM is 2.5v DDR3 RAM. It is compatible. This is not the problem.

JDPC · Apr 7, 2014

Is there any way of making sure the RAM is not compatible or faulty?

tiny voices · Apr 7, 2014

Not unless you can get the computer to boot to the BIOS.

tiny voices · Apr 7, 2014

A bent CPU pin and be VERY difficult to spot and can cause this problem.

JDPC · Apr 7, 2014

Ok thanks. I was thinking about that, I'm sure that I didn't damage the CPU pins when installing unless they were bent when I bought it.......
I tightened the heatsink down best I could but there is a bit of movement could it have bent a pin? Could a bent pin damage the mobo socket? (I doubt it but want to be sure....)

Thanks

tiny voices · Apr 7, 2014

A bent pin will not damage the socket. You also cannot bend a pin after the CPU is installed.

ModernWarfare · Apr 7, 2014

have you taken out all cables from the mobo and replug them with pressure?

JDPC · Apr 7, 2014

Yes, I reconnected all the cables. "tiny voices", the RAM is 1.65v ddr3, would this make difference?

JDPC · Apr 7, 2014

Just found out now that my RAM is "designed specifically to support the Intel Core i5 and Core i7 dual channel memory DDR3 solutions"....... :L (CMX4GX3M2A1600C9)

ModernWarfare · Apr 7, 2014

have you tried clearing cmos? take out the silver round bettery for 40seconds and put it back and see if that might work.

tiny voices · Apr 7, 2014

JDPC :

Your RAM is perfectly fine.
