Hello, my computer have been running into problems these past few weeks:
1) Automatic Boot Up:
My computer have been booting up (turning on) by itself after a manual shutdown.
* It doesn't automatically turn itself back on after a manual shutdown, it happens a couple hours later.
When an automatic boot up does occur, the computer either goes through a restart sequence (it turns on then
off after a few seconds or minutes and repeats), or it turns on by itself and stays on.
*This event happens mostly in early mornings around 2 - 4AM

2) Unexpected Shutdowns:
In addition to the auto boot up problem, my computer is also experiencing random shutdowns. At times it
shuts down after around 30 minutes after I turned the computer on, and other times after a couple of hours. There are also times when it doesn't shut down at all when I'm using the computer.
* When there is an unexpected shutdown, most of the time the computer do a complete shutdown (it logs off
windows first). Sometimes it would just shut off as if someone pulled the power plug off when the computer is running.

I checked task scheduler to see if its responsible for the automatic boot ups. No task were given access to wake computer to run the task. I even scheduled the tasks to run during times I'm using the computer, but it didn't fix the problem. I also tried changing windows update to install update instead of 3AM to 11AM, but still no luck. I searched online to see if anyone else is experiencing the same problems as I am, and it seems mostly people are suggesting that the problem lies within the power supply. *Before all these events occur, I actually experienced a BSOD while my computer was put to sleep, could it be related somehow? Any ideas on what might be causing these problems? I'm a novice on computers, so I do apologize if I'm not using proper terms or for not understanding the terms you guys use.

My computer is a Gateway DX4840 with Windows 7 64bit Home Premium. Processor is Intel(R) Core(TM) i3 CPU 550 @ 3.20GHz

Howdy,

Your PC doesn't seem that old for the PSU to be going but it can be.

Turning off after awhile can be something overheating like say CPU or GPU or power supply. Turning on by itself is a little harder to trace.

I'm not exactly sure at what temperature is considered overheating for my computer. Are there any programs you know and could recommend me for monitoring the temperature for CPU, GPU, and power supply?

I checked my BIOS settings, it doesn't include include wake on lan or ring, but this is what it have:

ACPI Suspend Mode [S3(STR)]
Deep Power Off Mode [enabled]
Power on by RTC Alarm [disabled]
Power on by PCIE Devices [disabled]
Power on by PCI Devices [disabled]
Wake Up by PS/2 KB/Mouse [enabled]
Wake Up by USB KB/Mouse [enabled]
Restore on AC Power Loss [Last State]

Are there any methods where I can check if a power supply is turning bad?

Like Dai says, disable the two options for "Wake on XXXX KB/mouse". I'm guessing you have a cat or something that likes jumping on the keyboard in the middle of the night!

From what I know the video card in my computer is integrated. I looked at the power supply label, this is what it says:
FSP Group Inc.
Model No: FSP300-60THA(1)
AC Input: 100-127/220-240V~, 7/3.5A, 60/50Hz
DC Output: 300W

Do I need a certain type of power supply that is compatible with my computer? If so, do you know what information I need in order to find the right power supply to use?

I won't be able to borrow any power supplies from my friends for the time being, so yeah in terms of buying, what information do I need to get the right power supply?
