nothing to do with the ram ... this motherboard sometimes locks, ( dont ask me why) but if you take out the power cord for 5-10 minutes and then press and hold the front power button on the machine (about 10 seconds) it will reset the board. Plug in the power cord and the basic items, sound, video etc ( some usb devices tend to stop it booting to) boot into windows. Then add the rest of your usb devices ..

Top view photo of the motherboard, of an MSI MS-7525 motherboard made FOR HP by MSI, for a Compaq Presario SR5410F Desktop PC,
Also scroll down the page, and click on the + sign to the left of -
A) 24-pin ATX main power cable:
In the photo, look to the right of the Blue ram memory slots.
The Yellowish/Whitish connector to the right of them, with two columns of 12 socket holes, is where the 24-pin ATX main power cable plugs in.
In the Motherboard Layout it is marked by - ATX1
This is a general example of a 24-pin ATX main power cable, and it's respective connector on the motherboard,
Note the middle photo, and the Lock on the side of the power cable's connector. The Lock has a hooked end that goes over a Tab, on the motherboard's connector.
The Lock works like a see-saw on a playground. The top is squeezed in, and this brings the hooked end away from the Tab, in order to remove the power cable.
When assured that the power cable is plugged in tightly, and therefore correctly, the hooked end of the Lock will be over the motherboard connector's Tab.
B) 4-pin ATX +12 Volt power cable:
In the center of the motherboard, under the Processor socket, is the Northbridge chip. (Part of the motherboard chipset)
It is under a finned aluminum Heatsink, that resembles a meat tenderizer's head.
Draw an imaginary line up above it, in-between the Processor socket, and the aluminum finned Heatsink, and go straight LEFT.
See the whitish 4-socket hole square connector?
In the Motherboard Layout it is marked by - JPW1
This is where the 4-pin ATX +12 Volt power cable plugs in. It is power for the Processor. Has the same locking setup as the 24-pin ATX main power cable, and it's motherboard connector.
C) In the Motherboard Layout to the top left corner of ram memory Slot 1, (DIMM1), is where the Processor fan connects.
D) In the Motherboard Layout just below JPW1 is where the computer case fan plugs into. SYS_FAN1
E) In the Motherboard Layout - SATA1 - is where the SATA Harddrive data cable plugs into. (Below ram memory slots)
The SATA power cable from the power supply, plugs into the SATA harddrive. Note that the SATA power cable's connector, is longer in length than the SATA data cable's connector.
[SATA power cable has 15-pin. SATA data cable has 7-pins ]
Note that both cable's connectors, have an L-shape on the inside.
This is what a 4-pin standard Peripheral power cable looks like,
IF, your SATA harddrive has a provision for a SATA power cable, AND a 4-pin standard Peripheral power cable, ONLY use just the SATA power cable!
Otherwise you will burn up the SATA harddrive. May not happen right away, but I assure you it will happen!
[ A note on SATA.
The beauty of SATA, is that you can plug into ANY SATA connector on the motherboard, and BIOS will see it.
If you plug the Harddrive into SATA 1, or SATA 2, or SATA 3, or SATA 4, connector on the motherboard, IT DOES NOT MATTER.
BIOS will find the Harddrive, or optical drive ]
The Front of your computer is the Front Panel.
The area of contact pins on the motherboard, that the main wires from the Front Panel go to, is the Front Panel header.
In the Motherboard Layout illustration, the Front Panel header is down at the Bottom/Right corner, and is marked - JFP1.
(Right in the very bottom/right corner is JUSB2. JFP1 is right above it)
JFP1. Junction Front Panel 1.
9-pin header. Black rectangle.
5 pins on the Right side, 4 pins on the Left side.
The pins are numbered EVEN on the LEFT side.
Starting on the BOTTOM going UP;
Pins 2, 4, 6, and 8. There is NO Pin 10.
The pins are numbered ODD on the RIGHT side.
Starting on the BOTTOM going UP;
Pins 1, 3, 5, 7, and 9.
A) Pins 1 and 3 are for the HarDDrive activity LED.
(Light Emitting Diode, so it is a light )
Pin 1 is for the Positive ( + ) wire. If the HDD LED is dim when the harddrive is active, switch the wires around.
B) Pins 5 and 7 are for a Reset switch, IF a Reset switch is used.
C) Pin 9 is N/C. Not Connected. 5 Volt power, and reserved for the factory to use.
D) Pins 2 and 4 are for the Power On LED.
Pin 2 is for the Positive ( + ) wire.
If the PWR ON LED is dim when the computer is on, switch the wires around.
E) Pins 6 and 8 are for the Power On switch.
