Problems with a new build...YIKES!

[rivbyte]

MSI B85-G41 PC Mate (flimsy board)
I7 4770 3.4
Intel stock CPU fan...piece of crap
16 GB DDR3 (1600-12800)
Seasonic S12g 550W PSU
EVGA GTX-750 (1GB) GPU. I wanted more but $$$
Samsung EVO 250GB SSD
Seagate 2TB HDD
WD 500GB HDD
ASUS 24x DVD/CD burner
...Also a Pioneer DVD/CD burner, but
unfortunately, it is IDE, can not use it!

Ok, I finished installing everything, (except the GPU) it stated I have to update the bios, before installing, really?)

I had a problem With the CoolerMaster Hyperlink 212 tower, 1150 socket was a small after thought on the box, but the original print had all sockets listed except for the 1150. I still had a problem with the small pin on the bottom of the CPU cooler that after the middle pin got into the hole, that small 1/8" pin on the left side caused the cross bracket not to fit. I cleaned off thermal paste, and just used the Intel stock fan.

When finished, I just happened to spin the CPU stock fan blade and the blades were hitting the aluminum heat sink, played with a while and now it's intermittent, (but not under power) It may free itself, hopefully.

Ok moment of truth arrived, I powered it on, then nothing. I checked all the wires again. Maybe it's the 7 year CoolerMaster 690, but in looking at the MSI B85-G41 board, it has a 9 pin JFP1, and. 7 Pin JFP1, I don't see any pinheads for this header, so I plugged the 9 pin into JFP1, where the case front panel connectors go. Is it one or the other?

I also bought a multiport 2.0/3.0 USB, and that 9 pin USB plugs into USB1, and the case top USB connectors plug into USB2 connectors. This multiplier also has a Sata and the 3.0 bigger connector next to the 24 pin ATX header.

I also have a 9 pin 1394 case connector (ground,cable pwr,tpb, ground, tpa,) It belonged to the FireWire on top of case, never used it with storage drives, just my 2.0 USB. goes, since it's old technology. I also used the onboard LAN for internet.
think I was using the I/O IEEE 1394 Ethernet plug, and my old board had a 1394 pinhead.

I should have looked over this board before buying, because I have a fairly new Pioneer DVD/CD burner, that is not Sata, but IDE, so now I have to buy another Sata burner. Also, while working on the board, it seems more flimsy than my MSI P-35.

Have a nice Day!

Unplug all the extra connections from the motherboard (Firewire, USB Adapters, basically anything not needed for a test boot) and see what happens.

the board may also be grounding.

Check to see that you dont have any extra screwheaders touching the motherboard.

best way to test this (if unplugging all cables, 1 memory stick doesnt work) is to remove the mobo and try having it post outside of the case

On my Old MSI P-35 Platinum, it had 8 or. 9 Mobo stand screws. (Correct name escapes me) This new B85 has only 6, are these universal in size, I did not see any of these with the new Mobo, are they usually included? I'll look again.

I was careful, counted only 6 screws, lined them up. I ended up using the Intel stock cooler, so there is no retaining bracket on the bottom making contact with case.

I went to Fry's and bought a CoolerMaster 550 PSU, I was going to try that first, would that cause any problems? (24 ATX PWR, & 4+4 CPU)

I'd try that before disconnecting all, and removing to check below the Mobo. But then again, no power, which is either a bad PSU, or like you said, it grounding out.

Thanks ! The board cost $60.00 on Newegg, maybe it's a cheap board and should have gone with something else.

At Fry's I also bought a IDE to SATA adapter, so I can still use my other Pioneer ODD.
Thanks

No power, so I hooked new Seasonic PSU to my old MSI P-35, and board light went on, so it's not the power unit..good!
Knowing I have power, and checking the other side panel and saw 6 stand screws, so I know that can't be shorting out the Mobo.

Thinking now it's not the ground or PSU, there's got to be something going on with the Mobo. So I went over my whole system again, flipped the switch and now at least the fans spin up, then shut down one second later, using the case power button, but reset button did not work.
So I went over the JFP1 header illustration on page En-20, the MSI Manual for this B85-G41, and in looking at these pins, switch

JFP1 is a 10 pin ( less one #9 reserved)
Looking head on with the top left,
-------------------------
+ - + -
Power LED / Power Switch
--------------------------------
+ - - +
HDD LED / Reset Switch
---------------------------------
I noticed on the back of the NEG pins, there is a small arrow. According to the illustration:
~On the top row (4 pins) it's-
PLUS/MINUS then PLUS/MINUS
~On the bottom row (5 pins) it's-
PLUS/MINUS then MINUS PLUS.
I just flipped the reset pair over so now it's +\- & -\+.
So the fan powers up just for a second, then shuts off.
Now what could be going on?
Thanks!
