Computer keeps turning off

My PC was leaning against an item of furniture. It slipped and fell about 8 inches onto the side where the motherboard is. Since that time, the PC has been shutting down at random moments. Power is cut and it is immediately turned off.
How can I diagnose what is causing this? What do you think it is likely to be?
Thank you

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Dr. KlahnPrincipal Software EngineerCommented:
In this situation, I'd:

  • Look in the Windows Event Viewer to see if there are any log entries associated with the shutdowns
  • Open the case
  • Disconnect *all* cables from the motherboard
  • Extract the motherboard and look for damage
  • Remove the CPU and cooler from the motherboard, then reseat them
  • Extract the memory from the motherboard, then reseat it
  • Reconnect all cables to the motherboard

Then run the system and see if the problem goes away.  If this doesn't resolve the issue, then the next step is to start swapping parts in and out, and the easiest one to swap is the power supply.  But shortly after swapping power supplies the number of parts to swap next explodes, and if you aren't a PC shop with spares on hand it becomes both cheaper and less trouble to buy an identical replacement system off fleabay.

I think the board might have been damaged at the standoffs supporting it.

I agree with the above - get a new board as that will be the easiest component to be damaged the way you describe it.

Check the CPU temperature.

Agree on checking the event viewer logs.  You could have damaged your hard drive (my first thought(

Could be just about anything.

CPU, cooler, motherboard, power supply, hard drive etc etc.

Apart from event logs as suggested, you proceed as Dr. Klahn suggests above.  This isn't pretty stuff ...

I removed and re-seated the graphics card in its slot. That resolved the problem. Unfortunately nobody suggested this so I don't know how to award the points...but thank you for the suggestions.
