Diagram put back together

Not to much information from you . Here is a E-Machine assembly for the motherboard .
The power switch is a 2-wire connection to the Motherboard. The 2 pins on the motherboard it connects to will be labeled something like PW. The polarity on it doesn't matter. There will also be a power LED connection. Usually those wires are green and black. Green is positive. There's also a hard drive activity LED with (usually) red and black wires. Red is positive. Hopefully that polarity will be marked on the motherboard. If not, try it one way and if the LED doesn't light up, try it the other way. The power (green) LED should be on whenever the PC is on. The hard drive (red) LED will be on whenever the drive is being accessed. There might be pins on the motherboard for reset. Some computers don't have a reset button. In that case you wouldn't connect anything to it. If your case does have a reset button then connect the wires to the reset pins on the motherboard. Polarity doesn't matter for that.

Hope this helps

I have installed a new motherboard in an acer case. The power cable from the switch on the front of the case will not connect to the board. Can anyone help? Thank you

You should read the motherboard manual, for cabling:
1. Power SW
2. Reset SW
3. HDD led
4. Power led - and power led +
5. Speaker

Cabling scheme, also written on the motherboard.

If the Power SW not installed the switch on does not work.
If the Reset SW not installed the switch reset does not work
If the HDD led
not installed the hard drive light (red) is not lit
If the Power led (+/-) not installed the power light (yellow) is not lit
If the Speakers are not installed, when the computer is on the beep sound is not heard.

I hope this information helps.

Info to connect front panel leds

Each of the ends of the cables that lead to the LEDs should be labelled, e.g., 'PWR/power', 'RST/reset', 'SPK/speaker', 'HDLED/hard-drive-LED', 'PWRLED/power-LED'.

Connect each labelled connector to the labelled pins on the motherboard.

there is a possibility that you may have pulled off the power switch, to motherboard Connector.
This will be at the bottom right hand-side of the Motherboard.
You should have a 2 cable connector for. pwr/sw Power Switch. hdd/led Hard-Drive led. rst/sw reset Switch.
Check those First. if you didn,t remove the power lead, before attempting any work. you may have arced a current, and damaged the motherboard Or PSU. check the Fuse In The Actual plug lead. to determine the actual power Switch, without a multi-meter. remove the power lead, from the Computer. remove the power/sw connector From motherboard, And Bridge the power/sw with A plastic jumper Block. then replace power lead, and should boot up. If it does the fault is the actual power switch faulty.
