You need to BOOT from your cd - not just use it in windows.  Put it in the drive - then cancel anything that pops up - shutdown your machine leaving the CD in and then restart - watch the screen for the command to press any key to boot from CD - follow the instructions and do a windows REPAIR/REINSTALL - this will replace the missing files.  If you don't get the prompt to boot from CD then you need to go to the bios and enable the CD drive as your primary boot device.

It could be many things.... start by disconnecting  your Hard Drive... if it still restarts and does not let you stay in the bios try a new Power Supply... if persist its most likely your motherboard... make sure to disconnect  everything else...

If this is a problem that started out of the blue without you touching any of your settings, chances are there is a problem with either your motherboard, graphics card or processor. I had this same problem and it turned out that my motherboard had burnt out.\n\nI don't know how old your computer is but if it is more than 3 years old, chances are it is burnt out and you will need to replace your base unit.

If all else fails do a system restore and set it back to a time your PC was working OK, you'll find it in "start" "control panel " "performance and maintenance" Right side panel "system restore"

Sounds like you have a bug. Take your computer into a repairman (or repairwoman).

if it happened recently try system restoring it back to before it started. Click START - All Programs - Accessories - System Tools - System Restore. Then as i said restore it to the point at which you think it worked.

Sounds like a virus. Update whatever virus scanner you have then scan the computer in safe mode.\n\nYou get into safe mode by hitting the F8 key while it's booting up at the very beginning.

There could be quite a few problems, but this could also be a fairly simple fix.  I would first try to just unplug the whole darn thing, wait about 30 seconds, and then plug it in again and try to start it.  Seeing as you have internet access, I would also try going to this website: http://h10025.www1.hp.com/ewfrf/wc/document?docname=bph07173&lc=en&cc=us&rule=14694&dlc=&product=396431.  That hopefully will help. =)  Good luck!

Actually there is another step you need to check:\n\nyou might wanna check your BIOS setting if even the USB ports are activated   :D\n\nTo get into BIOS, when you start your computer, you should see something like "press f1 for setup", or "press del for setup", etc.\n\nBE CAREFUL WHEN YOU ARE CHANGING SETTING IN BIOS. ANY WRONG SETUP MIGHT MAKE YOUR COMPUTER FAILING TO STARTUP. MAKE SURE YOU SAVE THE CHANGES BEFORE EXIT.\n\nHope it helps....

u can't solve this problem unless u  repair the hardwares from ur pc. it might have an bios problem or ur hdd it's dieing... If u still got quaranty for it they should fix it.. if not go search some "hardware repairing shops" [could find a sinonime for that :P].

If you have any devices connected to your USB or Firewire ports (printer, scanner, external hard drive, etc.) disconnect them all.  \n\nOnce you get to your desktop and can access the start button, do a disk clean up and defrag (start > programs > accessories > system tools > disk cleanup then after it finishes running, defrag.)\n\nMake sure you run a current antivirus and antispyware.\n\nNow that you've got a cleaner system, see if the startup problem has been fixed.  If it has, great.  Plug your devices back in, one at a time.  Try starting the computer after each device is plugged in. If the startup problem returns, you've isolated the cause.\n\nBut if you've cleaned the system and the startup problem is still there, try reinstalling your operating system.  And if that doesn't help, you might have a bigger problem with the motherboard, the BIOS, etc.  In which case you might have to go to your computer manufacturer's support site to download the latest drivers or get some one on one tech help.

either your harddrive is crashed, of it is bad. It need major work, if you were here where I lived you could bring it to me, but you should take it to a shop where they can find out the problem
