You need to look at Windows Repair Your Computer options.

  • Startup repair - This automatically fixes problems that are preventing Windows from starting
  • System Restore - This will Restore Windows to an earlier point in time
  • Windows Complete PC Restore - This will completely restore your entire PC - programs, system settings and files - from a back up that you have previously created (Available in Windows Vista Business, Enterprise and Ultimate editions only)
  • Windows Memory Diagnostic Tool - This checks your computer's memory hardware for errors
  • Command Prompt - This opens a Command Window

With the Complete PC Restore Option you must have made a backup of your system, either on your hard drive or on a set of DVDs, in order to use this option. If you don't have a backup then don't use this option

How you access the repair options will depend upon whether you have a Windows installation disk or whether your operating system came pre-installed by your PC manufacturer.

Pre-Installed Options NOTE

If no repair options are available your PC manufacturer may have replaced the tools or customised them. Check your Computer Manual before proceeding.

1/ Start your PC

2/ If your PC has one operating system Press and Hold the F8 key as your PC starts. If the Windows Logo appear you will need to start again

3/ If you have a dual boot system a Boot option menu will appear. Highlight the Windows operating system and Press the F8 key

4/ In both cases, if all has gone well, an Advanced options screen will now appear

5/ Highlight the repair Your Computer option and Press Enter

6/ Select a keyboard layout, and then Click the Next button

7/ Next select your user Name and Enter your Password, then Click OK

8/ The recovery options should now appear

Windows Installation Disk NOTE

1/ make sure your PC can boot directly from the Windows DVD. Obviously, most modern PCs can. With older machines you may need to check the PC's BIOS

2/ Start the PC

3/ Immediately insert the Windows DVD into the DVD drive

4/ A Black screen will appear with the words 'Press any key to boot from CD or DVD'

5/ Press Any key to start the booting process

6/ A new screen will now appear with a progress bar. The legend say's 'Windows is loading files'

7/ After a few minutes the Microsoft copyright window ill appear and another small progress bar will be visible

8/ You will next see a Blue curtained screen

9/ After a short while the Language option screen will appear

10/ Select your language and keyboard language and the Click the Next button

11/ At the bottom left of the next screen - the Install screen, Click on the Repair Your Computer option

12/ The System recovery options will now search for your Windows installation

13/ Once the Windows installation has been located, Highlight it and then Click the Next button

14/ You are now presented with the set of recovery options

15/ Click on the Option you require and follow the onscreen prompts

im not getting any form of picture on my monitor at all so i cant do anything

I am not sure how the above has any bearing on the OP problem. You are obviously getting some power to the motherboard but the question is are you getting enough.Was the PC on when you moved it and the power lead popped out?

First thing to check is that the cable is fully plugged in, does the optical drive open? apart from the PSU (power supply) fan are all the other fans you have turning, including the one on top of the processor and graphics card?

  frizzy007 16:11 03 Aug 2012

the pc was not switched on at the time, but the plug was on at the wall, the fan that comes on is the one in the power supply box, but i dont think there is anything else running without opening the pc and switching it on.

  KRONOS the First 17:03 03 Aug 2012

Well can you do that?Just take the side off and press the power button and see which fan or fans come on and whether the CD/DVD drive will open.

But the way you are in no danger having the side off and powering up the PC.

Pulling the power cable out should not,in theory, do any damage but it is possible.

Hmm I read this as a corrupted drive thinking the plug had been pulled while switched on.

But maybe you have lost a line in the PSU

However a first check is to make sure nothing has worked loose while you moved it. A remove refit of the memory sticks graphics card wouldn't come amiss.

i have taken the side of the pc off to open it up. when i switched on the electric at the wall the fan in the power box started running and also the one on the back of the pc. the green light is on on the front of the pc and the disc drive door wont open, the scroll light on the keyboard is on and when i switch on the monitor it reads rgb no input signal and the monitor light goes from green to orange as if i have switched off the pc but not the monitor. i dont know if this will help diagnoise the problem. im going to price up a new power box i think. its an ISO-450PP 4S

What about the fan on top of the heat-sink, which is on the processor and any fan on your graphics card.

You will not need the exact same PSU any ATX power supply will do.There are plenty here: Ebay.

  frizzy007 12:18 04 Aug 2012

the fan on the processor wasnt working and i dont have one on the graphics card. will the other psu's have all the same connectors on???

  KRONOS the First 12:33 04 Aug 2012

Yes, pretty much. If the fan is not working on the processor then it looks as though you might well have a PSU fault.
