Update and run your virus control scan

Run a registry cleanup if you have a program for that

Go to toolbar>tools>internet options>general tab and delete all
cookies

Go to start>all programs>accessories>system tools >clean disc

If you have a separate spyware program ,scan for spyware

How many programs do you hae running in the background?Look at the lower right corner and the little icons there. Turn off anything unneccessary (leave your virus control and spyware control on)

After you have completed all this, get back to me if your computer still will not shutdown or restart.

Does it have an on and off switch? You may have to use it, but you may lose things, so do all of the above and get back to me?

What Could Cause My Computer To Shut Down For No Reason?


What brand of pc is this? Download a diagnostic program to test internal functions. Sounds like maybe a motherboard or power supply issue.

Tip

Annoyed that your Num Lock key isn't on when you start your PC?


Here's a quick tip to ensure your numlock key stays "ON" by default when the computer starts.
1. log off your PC to the Ctrl-Alt-Del screen
2. Turn on the NumLock key
3. Hit Ctrl-Alt-Del (like you are about to log on)
4. Don't log on, hit the "shut down" button to turn off your PC

This saves the numlock key in the "ON" position by default when the PC starts.

GM5664 shuting down


You can check temps in your BIOS. That'll tell you if it's an overheating issue.

If temps are normal, suspect a problem PSU or even other hardware. My first guess would be overheating though.
You can check for shorts on the board or bad capacitors. But these are pretty classic symptoms of an electrical or overheating problem. Your temperatures aren't indicating overheating, so there's something funky with the electrical/power system.

The fact that it shuts down with a higher performance mode to me would indicate faulty power.

It sort of seems to me that either you have two bad PSUs (unlikely but entirely possible) or you have a motherboard problem. Replacing a power supply is both cheaper and easier than replacing a motherboard. Now, if you get a third PSU and you're still having the same problems it might be time to look at the motherboard and it's components.

and also Swap the power supply for something like this one:

Newegg.com - SeaSonic S12II 620 Bronze 620W ATX12V V2.3 / EPS 12V V2.91 80 PLUS BRONZE Certified Active PFC Power Supply

/or/

Newegg.com - CORSAIR Enthusiast Series TX650 V2 650W ATX12V v2.31/ EPS12V v2.92 80 PLUS BRONZE Certified Active PFC High Performance Power Supply

Disable num lock


Deskop or Laptop seems to be a contradiction >????

The num lock (number or numeric lock) can become annoying if you tend to accidentally hit the num lock key on your laptop and turn it on or off.
Disabling the num lock completely involves editing the system registry.
Before performing such edits, always save and back up your computer information in case you make a mistake, as the system registry controls many aspects of your computer's operation.
Once you have disabled the num lock on your laptop, you must edit the system registry again to re-enable that function.

Close all windows and programs that are running on your computer.
Press the "Windows" key and the "R" key simultaneously to open the "Run" dialog box.

Type "regedit" without the quotation marks, then press "Enter."
Click the "+" symbol next to HKEY_CURRENT_USER, then select the "+" symbol next to "Control Panel."
Click on "Keyboard."
Double-click "IntitialKeyboardIndicators."
Enter "0" (the number zero) in the "Value Data" field to disable the num lock after logon, or enter "1" (the number one) to disable the num lock entirely.
Click "OK," then close the registry by clicking the "X" in the upper right corner of the registry window.
Restart your computer.
To re-enable num lock, follow the same process, but change the "Value Data" to "2."
