Power is on but it just keep restarting constantly and power cannot stay on for the computer to boot.

Now to get to safe mode, is a couple different ways depending on your OS.

For Windows 7

• During boot up, press F8 before the windows splash screen, this should give you the option to boot up into safe mode.

For Windows 8

• Open up the charms bar
• Click Settings
• Hold Shift before pressing the power icon
• While still holding shift, click the power icon
• Keep holding shift, and click restart
• You may release shift

After restarting Windows 8

• Once the PC boots, you'll see a screen that says "Choose an Option"
• Click "Troubleshoot"
• Click "Advanced Options"
• Click "Windows Startup Settings"
• The computer will restart
• When the computer turns back on, you'll have the option to boot into safe mode.

Restarting when? While booting?

If you have having boot problems and the systemkeeps restarting, then turn off the computer, then hit the power button andimmediately start hitting the F8 key repeatedly until you see SAFE MODE. Scrolldown past Safe Mode and you will see an option to DISABLE AUTOMATIC RESTART.Take the Disable Automatic Restart option.

unlock deepfreeze then restart computer , when finish boot , windows open , INSTALL HP DRIVER , when finish lock deepfreeze to protect your PC then restart again.

sounds like a bad power supply... get one from newegg.com they are easy to replace, it will only plug in to the place it is supposed to.... check wattage out put and get same or higher

Hi,

To resolve this issue, shutdown the computer and Restart it, as soon as it restarts keep on tapping F8 key, now select, "Last Good Known Configuration" and hit "Enter" key. It should take care of the issue. If not, then boot the computer to "Safemode", to do so, restart the computer and as soon as it restarts keep on tapping F8 key, now select "Safemode" from the Advance boot menu. If it is booting to Safemode, then perform a system restore to previous date. If nothing happens, then you have to perfomr a full system restore.You can restore the computer back to factory default,to do so, follow the below steps: Turn OFF the computer, now as soon as you hit the power button, keep on holding "Alt" key & keep on tapping "F10" key, i.e Alt+f10, it will open the recovery console, select full factory restore and follow onscreen instruction. NOTE: This will erase all the datas on the computer.

Thanks and Regards,

Restart your computer.
Press F8 repeatedly until the Windows "boot menu" (black-and-white) is visible.
Select "Safe Mode".
Click Start
Click Control Panel
Click Classic View
Click System
Click Hardware
Click Device Manager
Expand each branch of the hardware-tree, and remove all the components installed by that "chipset-driver".
Keep doing them all, and then restart your computer.
Windows should re-detect your hardware, and load the correct drivers.

If that fails:
Restart your computer.
Press F8 repeatedly until the Windows "boot menu" (black-and-white) is visible.
Select "Safe Mode".
Click Start and navigate to "System Restore".
Choose a check-point dated at a date/time before your screw-up.
Choose "restore" to that date/time.
Follow the on-screen directions.

RESTART YOUR COMPUTER, ON REBOOT, CLICK F10 WHEN YOUR CHANGE BOOT OPTIONS SCREEN COMES UP. YOU MUST PRESS F10 QUICKLY OR IT WILL LOAD WINDOWS AND YOU WILL HAVE TO RESTART AGAIN. ONCE YOU GET INTO THE BIOS SETUP UTILITY GO TO SYSTEM CONFIGURATION, SCROLL DOWN TO BOOT OPTIONS CLICK ENTER. GO DOWN TO INTERNAL NETWORK ADAPTER BOOT AND ENABLE IT. THEN GO TO SAVE AND EXIT. AFTER YOU RESTART YOUR COMPUTER, CHECK IF THE WIRELESS IS WORKING. IF LATER IT FAILS AGAIN, GO BACK INTO THE BIOS SETUP, IF THE ADAPTER IS STILL ENABLED, DO A DIAGNOSTIC TEST FROM THE BIOS UTILITY. IT WILL DO A QUICK TEST (IT IS FAST) THEN IT WILL DO A COMPREHENSIVE TEST, THIS WILL TAKE AWHILE UNTIL IT FINDS THE PROBLEM. BE PATIENT IT WILL FIX IT!!! THE COMPUTER SHOULD AUTOMATICALLY SHUTDOWN WHEN IT FINISHES. WHEN YOU TRY TO TURN YOUR COMPUTER BACK ON, IT MAY NOT COME ON THE 1ST TIME, THIS IS OK TOO. JUST KEEP PRESSING AND HOLDING THE POWER BUTTON UNTIL IT COMES ON AND STAYS ON. NOW WHEN YOUR COMPUTER LOADS WINDOWS YOU WILL SEE YOUR WIRELESS ADAPTER IS WORKING.

Check the power setting in control panel of windows. If you have a monitor from another computer swap them and see if the problem stays with the computer or monitor.
