My HP Pavilion XT936 shuts during bootup. Wh could be the cause?

I need more info.\nDo you ever see the Windows logo? If so then there is probably something wrong w/ the windows files. Trying tapping F8 during bootup and select "safe mode"\n\nDo you just get the HP logo? Then it's something hardware related. And that could be almost anything. Did you change anything else besides the hard drive?\nThis board also seems pretty old, so it might just be dead.

Sounds like a virus. Update whatever virus scanner you have then scan the computer in safe mode.\n\nYou get into safe mode by hitting the F8 key while it's booting up at the very beginning.

1. It could be in Hybernate: try to turn off all power and restart the whole thing from the no-power stage.\n\n2. graphic-card / video setting: \n2.1 there's nothing much you can do if you cant see it but i suggest to turn it all off from the no-power stage and press <del> to go to your BIOS setting. Check if you can mannually overide the settings to a lower mode. If so, try restarting again.\n2.2 from the background, the laptop is starting up with windows but u cant see anything coz the video just might have been toggled with. try pressing <F8> by the time you boot it up, chances are u might be lucky enough to go on safe mode and u can level your video setting to a lower degree.\n\n3. if 1 and 2 doesn't work - i damn hope you have backed up you files coz you have to bring it to a DELL shop\n\nHope I helped you out- coz i had that prob once and # 2 did the trick for me

Installing chipset drivers should resolve the issue. Here is the URL to download the chipset drivers from the chipset manufacturer's site :\n\nhttp://www.viaarena.com/Driver/via_hyperionpro_v510a.zip\n\nElse, contact HP online technician here :\nhttp://ipgweb.cce.hp.com/ipgna/caller/chat.asp?dd=pavd&productName=HP+Pavilion+a720n+Desktop+PC&productCategory=12455&SCOID=82702&PSOID=46153&aoid=null&lang=en&cc=us

are you powering up with your battery alone, or are you plugged into an outlet?\n\nhow old is your computer? is it worth spending money to fix it by going to a computer repair shop?  are your files very valuable?

I have an HP at my job that was having some trouble and it was hard for even the IT people to get info/parts on it. It was a modified ASUS board made for HP apparently. The beeps usually are Video errors or RAM errors. If you switch RAM and still have a problem the motherboard is probably toast. This model sounds pretty old, time to upgrade anyways.

It will do this if the computer is not properly shut down. Let it go into safe mode, and use the start>shutdown function from there. If it insists on going to safe mode and won't start any other way (after you pick normal start) then there is a big problem and you may have to reinstall windows.

This can lead to two things.\n\n1.  Power supply is gone\n2.  BIOS is gone

Try a different power supply and see if you still get the problem.. \n\nAlso check your memory (ram). There are some programs to do that the first one that comes to my mind is memtest86 http://www.memtest86.com/\n\n\ngood luck!

OK you do not provide a lot of information as to your system.\n\nFirst boot into safe mode by pressing the F8 key once the computer starts to boot. Choose command prompt only and see if it still shuts down.  If it does not that is good.  if it still shuts down, open the case and remove any expansion cards you may have installed except for the video card iof you have one.  Remove and put back in the memeory.  Look for lots of dust in the system also if there is a lot of dust then take the system outside and blow all the dust out with either canned air or an air compessor use care  not to blow too hard.  Pay attention to the poser supply.  After cleaning the computer out and reseating/removing all of the cards and memory restart the computer in safe mode and see if it stays on.  If so it is probably fixed.\n\nIf it still shuts down it is probably a bad power supply or the processor is overheating.  if you feel confident you can reseat the processor and replace the power supply.  If not ask the local computer nerd at work or a friend for help.\n\n\nIf the computer still shuts down it is probably something major.\n\n\nTo make sure a virus is not the problem just disconnect the power cable to the hard drive and boot the system.  if it will stay on but shuts down with the drive booting then there is a good chance you have a virus.  Do you have antivirus software installed and up to date?\n\nhave you tried system restore going back a week or so?\n\nRemoving a virus is a whole different question

been suffering a similar problem myself, spoke to an IT guy i know, says it may be a power problem, (need new supply) or processor overheating (may need new cooler)?  gonna get him to check mine, hope you get yours sorted, good luck

It is BIOS issue\nThere may be some message appears, read it well and see what is the problem\ntry to get into your BIOS and check there what is the problem

Unplug everything, replug it all back in.   Did you install the drivers properly?\n\nHP is the way to go next time.

First, you should turn off your Automatic Restart feature.  To do this, you must go to Start, Control Panel, System, System Properties, Advanced Tab, StartUp and Recovery button, and uncheck Automatically restart under System Failure.  What will happen instead of restart is a blue screen.  On that blue screen, there will be stop codes.  Write these down.  Then using a computer that works, enter them in google or go to Microsoft and find the place where you can search for these codes [google will probably be faster].\n\nBy and large, I think there is a problem with heat, probably your cpu.  You should get a can of air and blow out as much dirt and dust as you can.  You may have to remove the fan and clean the fan blades, and that will make it easier to clean the heat sink fins.\n\nBut this is not a sure thing - it acts like it, but getting the stop codes is important as it could be a memory module problem also.  And it could be a software thing, but I don't think so.

Mine did this _ Problem was I hade a card reader hooked up to my USB port and it stopped the computer from finishing the boot - check your USB plug-ins - Hope this helps!

Good information to help you resolve this would be:  new or used computer?  It could be shutting down for a multitude of reasons...  The first to come to mind is temperature.  Most motherboards shut down a few degrees before the processor's thermal breakdown point.  You may want to see that your heatsink is seated on the processor properly, and that any and all fans are functioning.\n\nAnother common culprit would be a virus.  Look for a free program that will let you do a boot time scan of your system.
