Without more info, this could be software OR hardware. Software as in bad or conflicting drivers for video, pci devices, ports, etc. or some significant part of your operating system. It could also be that some value in the BIOS doesn't match whatis actually installed. If no software was changed/upgraded/installed recently, it's more likely a hardware problem such as: a fan stopped (system gets too warm), power supply bad, failed cpu (or 'overclocked'), memory bad, video card bad, bad hard disk (possibly bad sectors, possibly catastrophic failure), bad motherboard. As you can see the list goes from "bad to worse" and from minor inconvenience to significant money to fix. Possibly I could give more likely answers with added data about your PC: model, OS version, applications, etc. but it sounds like it's time to visit a tech! Good luck. Will

With not much information about your computer system and Operating Systems.

Remove the cover of your case, and see if the CPU fan is running, if not, the CPU is overheating and causing you computer to shutdown.

Also check the power supply fan. If you can hear it working or feel air coming out of the back of the case. If it is not running, it will cause the power supply to heat up and the proper voltage will not be maintain, causing the computer to shutdown to cool off.

If the CPU fan is not working, order a new fan with ball bearings, and a bigger heat sink. HP puts in the cheapest fan and heat sinks, like all computer manufactures to save cost of systems. This is not an ideal situation for comsumers.

Good luck and have a great day.

Had a similar problem with a HP Pavilion 6735. The answer in my case was a defective power supply. When a power supply is failing it can cause ALL kinds of problems that can be very misleading as to the problem source. In this particular case, the user had just recently installed a NIC 3 weeks prior and then a modem a week after that. The power supply couldn't handle the extra pull and eventually burned out.Some of the problems that came up over this 3 week span:
Monitor display would "fuzz" or black-out.
System would shut down for no reason.
After a shut down, PC wouldn't boot sometimes.
Try opening your PC's case and feel the power supply for excessive heat or see if you notice a "burning" smell. After I replaced the supply with a higher wattage supply then the problem was solved.
Hope this helps.
