Take it in to a shop and have them look at your power supply. It sounds like that could well be your problem. If so, it is a fairly easy fix. Trust me, it happens way too often of late. Good luck.

if you tower was making a lot of whinning noise before it quit...your power unit/fan puked.  Common item to die when computers aren't cleaned out.\n\nSimple item to replace...just a big box where the power from outlet plugs in the back and inside just a few wires that plug into each item.\n\nCan aways use a meter to see if power is coming through the power box.  Not to mention ensure all connections are good and tight.  Make sure no breaks in any wires or plugs.

Yes,sounds like over-heating of the power supply unit.It was switching itself off every time it got over-heated.Most probably the cooling fan inside the power unit was not working.

I would check the power cord between the wall and the power supply.  Simple, but true; happens all the time.

Answer #1 - It could have been a quick power outage, you might not have noticed it if you were nodding off to sleep.  Another possiblity is that if you have an external USB hard drive(s) connected to your computer for additional storage, they can sometime cause random re-booting (and sometime issues with boot-up afterwards) due to I/O conflicts. Those are two possible scenarios that could have caused your midnight reboot.\n\nAnswer #2 - This definately sounds like your computers Power Supply fan.  Simply use a hose vacuum on the back of the fan and this should help. Another possibility though is that you left a CD-ROM in your computer and your virus software is accessing the drive to check it(sometimes CD's can make a humming noise if not seated properly in the drive).

The cmos battery shouldn't stop the computer from booting, it'll just boot with default settings each time. If you have a totally dead box check the power supply first. You should always at least get a fan whirring or something.

It's probably the cpu temperature alarm.\nDepending on your board, there is a temperature alarm built into the cmos.  If it is alarming, maybe your cpu is getting too hot.\nCheck your fan and make sure it's working well.  You may want to replace it with a bigger fan to keep it more cool

It is a painful exercise. Follow the steps in the Maintenance and Service Guide for the HP Pavilion zv6000 Notebook PC. You can find it here:\n\nhttp://h10025.www1.hp.com/ewfrf/wc/manualCategory?lc=en&cc=us&dest_page=prodinfoCategory&tool=prodinfoCategory&product=468790&dlc=en&#\n\nI recommend downloading all the manuals on the site, then copy them to CD so you will always have them (even if your laptop's drive crashes).

I once had a similar problem. Mine was opening and closing every second.....and I mean every second....non stop. It was a defective drive....HP had to replace the drive. Sorry for the bad news....your problem may be completely different.

I had the same problem. Is was an electrical surge from my power source. Caused by  the fan motor in the processor. I had the motor replaced and it is back to normal.

More likely, your fan is bad.  If it was the power supply, you would notice more issues with the actual computer.

There could be issue with the Power Management. I recommend you reinstall Power Management from Device Manager.\n\nTo reinstall Power Management, take the following steps: \n\n1. Click Start, Control Panel, Performance and Maintenance, and then System icon. \n2. This opens the System properties window. \n3. Select Hardware tab and click Device Manager. \n4. Click "+" beside System devices. \n5. Select ACPI Power Button. \n6. Right-click the device and select Uninstall. \n7. Restart the system. \n\nPower Management will get installed automatically on restart. \n\nIf the issue persists try checking for any BIOS update.\n\nAlso, you can use the following link which will help you perform some troubleshooting steps. It is from HP web site. But it has good troubleshooting steps. Try it out. Here is the link :\n\nhttp://h10025.www1.hp.com/ewfrf/wc/genericDocument?cc=us&docname=bph07147&lc=en\n\nHope it will resolve the issue.

I had a similar problem caused by an overworked power supply unit (PSU) which was cheap to replace, but in reality it's not going to be possible to diagnose over the internet as it could be any one of a number of hardware or software issues.\n\nMy advice would be to call some independent PC repairers. Some offer a no fix no fee service & should tell you up front what the cost is likely to be.

Could be the cooling fan or the hard drive. Check both.
