I've been having a problem with my PC it keeps shutting down. My PC specs:

HP Pavilion p6 series
Model: p6-2260ea
Processor: Intel(R) Core(TM) i3-2120 CPU @ 3.30GHz 3.30GHz


Here's some information about the crash:

Problem signature:
Problem Event Name: BlueScreen
OS Version: 6.1.7601.2.1.0.768.3
Locale ID: 2057

Additional information about the problem:
BCCode: 10d
BCP1: 0000000000000005
BCP2: 0000000000000000
BCP3: 0000000000001024
BCP4: FFFFFA8008A5EE40
OS Version: 6_1_7601
Service Pack: 1_0
Product: 768_1


The problem is I don't really know what to do. It's been suggested that I download CPUID's TMonitor. At the time of this typing I realise I have not downloaded Tmonitor but CPUID CPU-Z, not sure if that's any good but I will try to download the correct software but its seems CPU-Z may do the same thing as these other software. However I look at the data produced by this software and I don't know what to look at. I'm also reading an article that says this:

Your power supply should be delivering 3.3-, 5- and 12V inputs to your motherboard

Well 3.3 - 5- what? Volts? Watts? I'm assuming V is volts. Also mentioning the motherboard seems a bit vague are there specific components in the motherboard that need to be delivered to? I'm just a little bit confused does anybody have any suggestions as to were I should start because I don't want to buy a new power supply for no reason.

One last thing I've been getting problems with my xbox controller disconnecting, I've tried updating software, drivers and putting USB port in the back but it hasn't worked. The only thing I haven't done is check the power supply which can cause the xbox controller to switch off. Maybe the two problems are connected.
 


To help clarify. the figures 3.3, 5, 12 V all refer to the voltage of power delivered by a PSU. 3.3 volts, 5 volts, 12 volts.
In newer PC's (like yours) it is usually the amount of power that can be delivered on the 12 volt "rail" that is most significant because it is the primary voltage used by the CPU (processor) and the video card. But the 3.3 and 5 volt is also important as other components, including the aforementioned video card, use this power.
On the side of your power supply unit should be a label listing what amount of current each rail (3.3, 5, 12) can provide to the computer; The important thing here is not WATTAGE but current measure in amperage.
Per HP your PC should have a 300 watt powersupply.
OEM power supplies are notorious for being the "weak link" in the PC; it is where the engineers (the guys and gals who actually design the PC) can figure out precisely how much power the PC will use and they put in a power supply that can provide just that much power.
Matt has a very good suggestion, and it is usually the first thing to do when troubleshooting possible power problems: borrow a friends power supply and install it in your PC and see if that solves the problem. The PSU must be a known good, working psu.
Something else that can cause crashes: Heat. Have you opened your PC case and thoroughly cleaned the inside and parts with canned air and/or a vaccum? Dirt, dust and debris have been the downfall of many PC's, and cleaning them so they can run cool often brings them back to life.
There are a lot of things that can cause crashes, so repost if none of the suggestions solve the problem.
 


That does sound like a good idea but I don't have a friend to borrow a PSU from, however I might want to buy a new PSU anyway because I might want to buy a more powerful graphics card and I hear if you want to do that you need to buy a new power supply. I'm not too sure if I want to spend that much I think you can get an equal replacement for about £30.

The other option is to clean it out, that sounds like a good idea. I suspect it's not as simple as it sounds and precautions need to be taken. It's seems sensible to try this before buying a new PSU.
