I left my computer running overnight and this morning it was off.
When I tried to power it up, it wouldn't work - faint DVD spinning
sounds, no fans, no monitor or keyboard bootup. After work today
I tried again - now the fan is functional and the DVD drive makes faint
spinning noises - but no monitor connection or keyboard bootup. I
tried connecting a different monitor to the computer with no
success. I tried powering down, unplugging peripherals, plugging
back in, and powering up - no success. After many tries of
powering on and off, I finally got to a boot screen (Entering Safe
Windows mode, press F10 for setup, F11 for BIOS, etc)- but no
further. Please help!
Turn off the system remove all the cables from the back of the computer press and hold down the power button for 10 seconds now connect just the poer cable and try to tun on the system and as soon as it turns on tab the F8 key on the keyboard and then boot into last known good configuration

Remove the Power Cord, Open the Case and remove one of thememory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x onit with an ink pen. If it fails to boot then move the chip to the nextmemory slot and try rebooting. If it fails take the chip out and set itaside, then put the other chip in and try booting it in both slots. If itboots, just to verify that the chip set aside is bad, mark an x on it and putit into the open memory chip slot and try booting.
1.Check your power supply by using an Analog Volt Meter, you should check if the power supplied by your power supply is stable,
2.Check your ram if it is faulty. try to clean the lids of the ram using an eraser. If still your computer doesnt work, you should find a spare RAM and test if your RAM is working properly.
3.If you dont have any problems with your RAM, you should try unplugging external PCI cards, AGP Cards, on your motherboard and use the internal devices instead, like built in VGA, sound card, Network Interface Card,just to check if there are no faulty devices which stopped your computer from starting.
If it displays nothing at all through the boot process it's either the cable or the VGA card. It may be that the computer has gone into hibernate as it was left on overnight. Try pressing and holding the powerr button.
check your power cord to insure that you are getting power. make sure power cord is plug in the back.
look in back of computer. you will see a little orange switch. it says 115/220 click to 220. boot computer.
if computer boots up turn off and click back over to 115.
if it does not boot your power supply in your computer needs replacement.
For reasons yet to be determined, your computer is not talking to your monitor.
This could be the monitor cable came loose from the tower (this is our favorite, because it is such an easy repair), or something on the motherboard (that is, anything) that is not functioning and preventing your computer from starting.
Unplug the connecting cable, and plug it back in again, making sure that it is seated properly.
Do you hear any sounds besides the fans? You should be able to hear the faint clicking of a hard drive starting up also. If you hear this, the problem is not in the computer, but in the communication to the monitor.

I experienced this problem last night, and seemed to have fixed it this morning.
SYMPTOMS: HP Pavilion dv9000, Win Vista x64 Ultimate. Running on battery, battery level became critical; windows went into 'Hibernate' mode. Upon plugging in to mains power, and resuming the Windows session, the Wireless is still disabled, no matter what position the switch is in.
POSSIBLE CAUSE: Critical battery switches off the wireless network card to preserve power. Motherboard seems to log this status but when re-connecting to mains power the card does not receive power again. Uninstalling the driver and getting Windows to re-install automatically upon re-boot does not work.
SOLUTION: Charge up the battery whilst the computer is running. You can charge it to a substantial level, say, above 25%. Disconnect mains power so that your laptop is running on battery only. Set your wireless switch to OFF (this is usually to the left position, away from the orange indicator). Now run your computer down to the critical battery level again (perhaps overnight). In the morning when you press the power button, the 'CHARGE' indicator (looks like a lightning bolt) on the front of the laptop should flash quickly, indicating that there is no charge in the battery. Remove the battery from the laptop's underside. Wait a couple of seconds, then press and hold the power button for 30 seconds. Keeping the battery off the laptop, reconnect mains power. Boot up your PC. When at the Windows desktop and all your startup programs have finished loading, switch your wireless on (to the right position). You should now have a blue light, and wireless should once again be working. You can now re-insert your battery. You might have to setup your wireless network connection again as mine seemed to be 'lost', but at least hopefully the main problem is now fixed.
