hp pavilion wont start? help please.

[aaronglanza]

a few weeks ago i got a pavilion dv6700 off my brother, when i turn it on hp invent comes on the screen and shortly after it turns off then trys to start again, it repeats this process over and over, sometimes after it says "opperating system not found"

ive tryed a system recovery and also ran a diagnostics which the results were, for the primary hard disc self test "no IDE device".

and for the memory test "result passed" any help would be great thanks in advance.

No IDE device means it does not detect the harddrive. Reseat it, if that does not work it is either the harddrive or system board

i done that, tryed to start it and its now asking for the windows disc. should this happen?

[Gangles]

it can yes, if the OS was corrupt. Try F11 on startup to see if you can access the recovery manager. IF not, now that you have resolved the first issue, call HP for a set of recovery media

F11 first, to try to do a recovery
if that fails to load (try multiple times)
contact hp: 1-800-474-6836

Sometimes it is necessary to do a hard reset to erase all of the information in the temporary memory and regain functionality of your PC when it stops responding. For example, doing a hard reset is helpful if your keyboard quits responding, you cannot get your PC to come out of hibernation or sleep mode, or if a software program causes the PC to freeze.
The hard reset will not delete saved files on the hard drive.
Performing a hard reset
To perform a hard reset, follow the steps below.
1-Unplug the AC adapter from the notebook PC and remove from any port replicator or docking station.
2-Remove the battery from the notebook battery compartment.
3-Press and hold down the power button for about 20 seconds.
NOTE: Holding down the power button while the computer is turned off drains any residual charge in the capacitors.
4-Insert the battery and plug the AC adapter back into the notebook PC.
5-Press the power button to turn the notebook PC back on.
