|Tell us the make and model of your brand name system, or if you have a generic desktop system, the make and model of the mboard. |
The specific model of a brand name system is often shown on a label on the outside of the case somewhere, or it can often be determined by going to the brand name's web site and loading a program they have available, if Windows is still working, on the subject computer.
If it's a Dell computer...
Go here for how to find the Service tag "number":
Tell us what it is.
If it's a HP or Compaq computer.....
Scroll down a bit.
Look for the similar label on the outside of your computer.
Quote the specific model number - that's at the end of the first line.
Quote the Product number - that's on the third line.
If it's a Lenovo computer
Find your specific Product number and tell us what it is:
Finding my product number
The model, sometimes the make, of a mboard in a generic desktop system is usually printed on the mboard's surface in obvious larger characters, often between the slots.
I'm assuming this is a desktop computer.
What do you mean when you say Hard Boot ?
Did you unplug it rather than merely accidently shut off the mboard ?
Was there a power failure event just before you had this problem ?
Lightning strikes in your area ?
"disabling automatic reboot - no valuable info"
Did you get any message on a blue screen ?
If yes tell what it said - the text that is not generic.
If you see a STOP error, quote it - we don't need the stuff in brackets to the right of that.
If a problem file is named tell us what it is.
If no message on a blue screen....
It's probably a hardware problem, not a software problem.
Make sure there is nothing loose that is metal that may be shorting something on the mboard or under it..
If you tilt the case in various directions you may hear that there is something loose.
Make sure there are no metal mounting posts under the mboard that are NOT where a mounting hole is
Look for damaged wiring that allows bare wire to short to something.
Some mboards develop this problem - electrolytic capacitors were installed on them that were not properly made, and they fail eventually - the mboard manufacturer didn't know they were improperly made at the time the mboard was made.
Open up your case and examine the mboard to see if you have bad capacitors, and/or other findable signs of mboard damage .

- he says there are STILL bad capacitors on more recent mboards.
Pictures of blown capacitors, other components, power supplies, fried Athlon cpus, etc.:
There can also be defective capacitors inside the power supply that may cause your problem, or on a card in a slot.
Try a power supply from a different working computer if you can.
We frequently hear of problems caused by the capacity of the power supply being inadquate for the video chipset system power supply wattage/current requirements of a card installed in a slot.
If you have a video card installed in a slot, which model is it ?
What is the max (combined or total ouput) wattage capacity rating of the power supply ?
What brand is it ?
E.g. if it's BESTEC that's a likely culprit.
