Cat killed mouse

Best way to restart it from wake up is remove the battery (if it is a laptop) or push the power button for at least 10 seconds (or more) until you can't see any lights at all or any sound from the hard drive. That is the only way you can restart the computer if it is not waking up from sleep mode.

Power button is top left corner of keyboard above the "Esc" key.
If you are trying to shutdown from Windows 8, follow these steps:

1. Mouse over the little gadget in the lower right corner of the screen. (You can also move your mouse cursor to the upper left corner; same result. Or, you can press Windows-C on your keyboard.)
2. In the slide-out menu (known as the Charms Bar) that appears, click Settings.
3. Click the Power button, and then click your desired action: Sleep, Shut down, or Update and restart.

The mouse smells the odor of a cat and is trying to escape/hide. Tell the cat that this mouse is not edible. Reconfigure the mouse properties and choose Defaults

Touch pad usb or wireless mouse ?
Laptops use the convenient touchpad and integrated scroll mouse that allow you to use just your finger to navigate Web pages, documents and open files and programs. Just like all other hardware, the laptop's integrated touchpad and mouse can experience errors and problems that cause you to lose functionality for a length of time. Whether the laptop's mouse is not working because of internal errors or conflicts with another device, several "tricks" can work to restore it.

Locate the function "Fn" button on your laptop in the lower left corner of the keyboard. Look in the keyboard's upper row (the F1 through F12 buttons) for an icon of a touchpad or computer mouse. This keyboard button acts as the toggle switch to enable and disable the built-in mouse and touchpad function. Press and hold the "Fn" button together with the mouse icon button. Look for the disable/enable symbol that briefly displays on your screen. Slide your finger over the laptop's mouse and attempt to use it as normal. Press the Windows keyboard key if using Windows 7, type "main.cpl" in the search box and press "Enter." Press the left arrow key to navigate over to the "Device Settings" tab. Press the tab key to reach the "Enable" button in this section. Press "Enter" on your keyboard. Press the tab key to reach the "Disable internal pointing device" check box. Press the space bar to remove the check mark. Put your finger on the touchpad, and move the pointer down to the "Apply" button. Click "Apply" to save the settings. Close the mouse "Properties" box. Press the keyboard "Windows" logo key to open the "Start Menu." Press the arrow keys on your keyboard to navigate to the "Shut Down" or "Turn Off Computer" menu. Press the up or down arrow key to highlight "Restart." Press "Enter" to restart your computer and attempt to use the laptop mouse as it should normally function. Open the "Control Panel." Go to the "Add and Remove" or "Uninstall" programs section. Highlight any secondary mouse devices in the list that you have installed for your laptop, such as an external USB mouse. Select the "Uninstall" option to remove any software and settings associated with this secondary mouse. Restart your computer and attempt to use the built-in laptop mouse as normal. Check to see if the mouse is working properly. Press the keyboard's "Windows" button to open the "Start Menu." Press the keyboard's arrow keys, "Enter" button and "Tab" to navigate to and open the "Control Panel." Go to the "Hardware and Sound" section, and press "Enter." Navigate to "Device Manager," and press "Enter" to open it. Find "Mice and other pointing devices from the list" and open its "Properties" dialog box. Select the "Driver" tab and choose "Update Driver." Allow Windows to search the Internet for drivers and to update them automatically. Restart your computer after the drivers are updated, and use your mouse as normal.

Sounds like your keyboard is sending the wrong signal (the one telling your PC to enter sleep mode) to your motherboard when you press space key, which (if true) would indicate it's faulty. It could also be you've contracted a virus and is playing a particularly nasty practical joke on you (let's hope that's all it does). Try connecting another keyboard to your PC and see if that helps. If it doesn't, then you'll need to clean your computer of any viruses. Try also disconnecting your mouse and see if that changes anything. If your keyboard comes with a shortcut utility software for it, run it and check there's no shortcut set on your keyboard's space bar. You've additionally specified you're not using wireless keyboard, but could you also please write what OS you're on?

no but it is really easy

How can I wake my computer from sleep or hibernation?

On most computers, you can resume working by pressing your computer's power button. However, not all computers are the same. You might be able to wake your computer by pressing any key on the keyboard, clicking a mouse button, or opening the lid on a laptop. Check the documentation that came with your computer or go to the manufacturer's website.

control panel >power options has all the settings to change what mode the computer goes into when you close the lid eg.sleep hiberante etc. so set that up for starters. when you close the lid on some laptops they go into hibernation which can be difficult to come out of. I find it best to put the computer in sleep mode when i go for a break, then it only takes one push of the button to continue where i left off
you can extend or turn off stanby or have it go into sleep mode automatically in the power option setting, and while in control panel check wireless keyboard has full control. The click of the mouse should reactivate it from standyby so try sleep for now.
I hope this knowledge helps you
good luck
