I am seeking a solution to figure out why this PC randomly just powers off. Lately it usually only does it once an hour, but sometimes more offen.
I added a GeForce 8800 video card, and another hard drive the day I purchased it, and it has worked fine for about 1 1/2 years. It started doing this about 4 months ago, and I have no clue what the problem is. This is anoying mostly because I am constantly playing video games online, and download at night time while I sleep. I can never finish my downloads, because every hour I have to turn the computer back on.
Here are a few things I have done to try and solve this.
Remove new video card.
Remove added hard drive.
Run computer on Vista Home, XP, Windows 7, and Linux Mandriva 2009 all continue to power off.
Removed the CPU, and cleaned out lots of thick dust balls, and gunk between the fan and heat sink. I should take a picture of all the nasty crap trapped between the fan and heat sink.....
Removed power supply and cleaned out all the dust.
Installed updated motherboard bios drivers and information.
Checked all wiring inside to make sure its correct.
Turned off all energy saving options in bios.
Turned off all Screen Savers, Sleep, Hybernating Modes possible.
Not to long before this problem started, the power button seemed to get jammed. I just kept poking at it, until it released and would power on. I am thinking there may be a possability that it still has some pressure downward, and after time it eventually hold down long enough to power off the pc. I don't know if thats just silly or not, but if the pressure builds up until it turns off, and releases when I press it to turn it back on, may cause this. So perhaps, I will route another power on switch directly to the motherboard in place of the normal power on button and see what happens.
My only other thoughts on this matter, would be that the motherboard is bad. Or the power supply. I can handle the power supply being bad, thats a cheap easy swap. If the motherboard is shot, then I pretty much scrap the tower, and board then start over. I don't want to have to do this.
If anyone has any tips, or have had same problem. I would love to here it. I am running out of patience even writig this, I have to keep saving it into notepad incase of this problem.

I hope someone will shed some light in this problem of yours.
I own a Pavillion a6167c and have experienced a similar situation. My system was pretty stable ever since I bought it about 3 years ago, but lately has been crashing quite frequently, a couple of times a day or so. It started about a couple of months ago after what I thought was an automatic update to Service Pack 2 of Widows Vista Premium was made.
When it happens for me it usually shuts down when left alone or while it is in the sleeping mode, usually at night. Often it crashes with the cooling fan running on high speed. When this happens, the only way to restart the system is by disconnecting the power cord, depressing the power button for 15 seconds or so and then plugging the power cord again. This brings it up every time, but I am begging to get really aggrevated by this and I am concerned that one of these times it won't start again.
I tried online help from HP, but their chat session freezes / locks up after exchanging a few questions with the tech online.
I hope someone will shed some light on why this happens and how to solve this problem.

What I did last was take out my 8800 because it's fatass fan was sitton ontop of the motherboards battery, and then I took it out. Lots of crap and gunk under it, so that was cleaned out battery was then replaced, and of course time and etc. was set differenty. However my computer has been running for 12 hours strait, instead of 1. I hope this helps anyone who has had this problem. I am not saying its fixed, but its better. Do my steps from above as well. I am finally happy.
