How can i reboot my computer please - Acer Aspire 5500 5570-2609 Laptop

Please perform a firmware update on your unit through using GB manager.
If that does not fix the issue, attempt the following steps to perform an emergency reboot:
*NOTE: If you have a WORLD unit, please replace the MENU button with the PROPLAY button to perform this reboot.
1. Please make sure that the unit is turned OFF.
2. Hold down the MENU button, then press the POWER button simultaneously.
3. Once the LCD (screen) powers on, release the POWER button BUT keep the MENU button pressed.
4. Once you see EMERGENCY REBOOT on the screen, release the MENU button and wait about 3-5 minutes for reboot to factory settings.

You may also try the emergency reboot using your computer (most effective way) by following these steps:
1. Make sure the GolfBuddy is powered off.
2. Please connect your USB cable to the computer WITHOUT your unit.
3. Hold down the Menu button.
4. As you are holding the Menu button down, please connect your GolfBuddy to the USB cable.
5. Once you see the EMERGENCY REBOOT screen, please release the Menu button but leave your unit connected to the USB cable until the process completes.

First - re-seat the hard disk and reboot the computer. If the computer does not boot up then reboot and go into the BIOS configuration to see if the BIOS detects the hard drive. If it doesn't detect the hard drive then it could be faulty.
Then the hard drive needs to be replaced in the computer/laptop, Windows installed and the computer or laptop's device drivers plus your programs etc. to get a functioning computer/laptop again.

HI, Regarding this issue with the computer not booting to Windows,please press the F8 as soon as you reboot the computer you would get a black screen that says "ADVANCED BOOT OPTIONS" from here you would find an option that says "SAFE MODE" please use the up and down arrow keys and highlight this option and see if you are able to get into Windows in the safe mode.If you are able to boot into safe mode then we can restore the settings of the computer to an earlier date for which please click on Start->All Programs->Accessories->System Tools->System Restore.You would get the System restore window from where you need to select an earlier date wherein the computer was working fine and then the computer would reboot and you should be able to get the computer to work.

When you reboot the computer please press F8you will get "advance boot option" Please select "Last known good configuration" .
If it not working reboot the computer press F8 go to Safe mode. In the safe mode go to command prompt and type this command "chkdsk /f /r" after that please restart the computer. After restarting please go to Normal mode.

install new operating system,,,and try to install it again

as my knowledge if the computer restarting by themselves always there are some error occured in this one area possibility :

1. error in software
2. error in hardware
3. error by virus infected
4. operating system issue

BUT :).. if u get this trouble after take some advennture in networld/network.. i suggest u computer ar sugessted with "blaster virus" the virus are written to reboot your computer without warning. Usually these viruses will make the computer reboot ever 5, 10, 15 or 30 minutes after the computer has booted. so the best way is update your security first
that is the first step

the second :i suggest u to run your computer in safe mode wait for several minutes if not reboot while running safe mode follow this step :

1. From the desktop right-click on My Computer.
2. Click the Properties option.
3. In the System Properties window click the Advanced tab.
4. In Advanced click the Settings button under Startup and Recovery.
5. In the Startup and Recovery window uncheck the Automatically restart check box.
6. Click Ok.

if still rebooting in safe mode there the issue is likely not software related but something else

the third :hardware devices that are not installed properly in the computer can also cause random reboots. Make sure all the cables and expansion cards are connected properly to the computer. The best way to determine this is to disconnect and reconnect all cables and expansion cards.

If after following each of the above recommendations your computer still continues to reboot it is likely that you are experiencing a Microsoft Windows operating system related issue that cannot be explained. To help make sure this is the case please try the below steps.

1. Reboot the computer and enter CMOS setup as the computer is booting. If you are not familiar with how to enter CMOS please read through document CH000192.
2. After you have loaded the computer in CMOS setup let the com sit

hope u luck

Other solution maybe possible :

2. Disconnect all usb except keyboard and mouse
