First off, remove all pc cards, & switch out the HD with a known good one. Is the fan on the cpu rotating? If not after doing the above, I can't help you Fritz

Front panel connections


I don't find the Front Panel header pinout online, nor do I have an MSI MS-5191 in the shop.

I would suggest using one the LED lights with two wires.
(3-wire is a dual color LED)

There are two rows of pins. Usually the Power On switch, Power On LED, and Speaker; are on the same row.
HarDDrive activity LED, and Reset Switch are on the opposite row.

Speaker has 4-pins designated for it. All the others use 2-pins.
(Unless the PWR ON LED is a dual color jobbie)

Touch two pins next to each other, in the same row; with the 2-wire LED.
Start with finding the Power On switch first.

Usually the top row 1st two pins are Power On LED (Light)
Next in line are the 2 pins for the Power On switch.
Bottom row 1st two pins are usually HarDDrive activity LED (light)
Next 2-pins are usually Reset switch.

May not apply to a motherboard old enough to use a Socket 7 processor socket.
There may be 18 to 20-pins.
Bear in mind that many are not used, and probably 4 are for an internal speaker, for hearing BIOS Beep Codes.
May be two separate Front Panel headers.

Once you find the two contact pins in the Front Panel header, for the Power On switch; I would put the Power On switch wires on.
The small pin connector on the wire/s, will keep you from accidentally touching these two pins again, when the computer is on.

Now you have the two pins for the Power On switch, and the computer is running; then keep touching 2-pins at a time with the LED. (Light Emitting Diode)

LED stays on? You have the Power On LED (Light) pins.
LED blinks? HarDDrive activity LED (light) pins.
Computer restarts? Reset switch pins.

Look for abbreviations near the pins in the Front panel header.

PWR, Pwr, Pwr On, Sw, and SW; are just some of the abbreviations for the Power On switch.

HDD LED, and HDD are two for the HarDDrive activity LED. (Light)
(If it states HDD SW it is the Power On switch. Weird old way of marking)

RST, Reset, and RSW, are for the Reset Switch.
(Reset Button)

If you see 4 pins marked with a bracket ( [ -> Turn so it's horizontal), these are for the internal speaker.

Type MSI front panel connector in your search bar, and look at -> images. See if you can find an image of your MSI Front Panel header pinout.

You can bet MSI carried out that Front Panel header pinout, on other MSI motherboards, besides the MS-5191.

The MSI MS-5191 may have been a motherboard made by MSI, especially for a pre-built computer manufacturer, and not listed on their website as an OEM motherboard.
(Original Equipment Manufacturer)

Won't have the Front Panel header pinout, listed on MSI's support website. (Doesn't)
But you can bet there IS an OEM motherboard made by MSI, that the Front Panel header DOES match.

May be different expansion slots, or motherboard chipset, or whatever; but the same Front Panel header pinout.

Manual for 41t-ad motherboard


http://www.skyline-eng.com/index.cfm?fuseaction=product.display&Product_ID=8665

Bottom/Right corner of motherboard - Front Panel header. Take an LED with two wires on it, and touch pairs of pins. ( 2 )
When you briefly touch the 2 pins that turn it on, you have the Power On switch wires.

Do not touch these pins again, and test the rest of the pins.
LED stays on? You have the Power ON LED pins.
LED blinks? You have the HarDDrive activity LED.
Computer restarts? Restart switch pins.
Some pins do nothing, 4 in a row may be for speaker, some pins have +5 volts, and are not used either. (Factory use)

This issue sounds like a possible defective power supply. Possible PSupply fan failure or PSupply is under powered for all you're devices. Re-check all internal connections.
Use the link provided below to see if you're PS output is sufficient for all you're connected devices; http://extreme.outervision.com/psucalculatorlite.jsp

Problem to switch on the cpu


Disconnect the UPS from your configuration,
and connect the AC power directly to a wall outlet.
Press the ON/OFF button and release it.
If nothing happens, press and hold the ON/OFF button for 10 seconds, until the computer turns itself completely off.
Then, press the ON/OFF button, to restart the computer.

No power and blinking green LED


It may not be that the bios needs clearing, take the left side panel off and look for the 'JBAT1' terminal on the mobo and put jumper cap from pins 1-2 to pins 2-3 for a few seconds then back to pins 1-2. start the pc then set the time and date when prompted ans save settings.
