Anyway, recently the computer has been rebooting after its been on for while. It restarts on its own. It is happening more frequently now too, like its getting progressively worse. It started about a week ago.
Does this sound like a PSU problem.
 
This will not fix your problem, but it should stop the auto-rebooting so you can get a better idea of what's going on. Do this: (lifted from a newsgroup article)

Uncheck the Automatically restart on system failure option. You can access this option right clicking My
computer\Advance tab\Startup & recovery\settings.

Ok. once you've done that (and reboot so the change is permanent), when you get a failure, you should get a blue screen that will give you some indication of what the real problem is.

You can also look in your "Event Viewer". Here's a Microsoft article about how to use the Event Viewer.


Event Viewer explained

You want to look at both the "System" and "Application" logs in the Event viewer to see if there's any problems. A Red icon (like a stop sign) will tell you a very serious event has taken place. Yellow icons are "warning" icons...and white icons with an exclamation point are simply "information" icons that tell you that something has taken place.

There's ALWAYS going to be entries in the Event viewer logs, so don't freak out if there's a lot of stuff there. However, you're most interested, as I said, about headings preceeded by a red icon. This will point you to the errors you're having.

Now, once you've made the changes to your settings preventing automatic rebooting, make note of any blue screen error messages you get. Additionally, post any "Stop" errors you see in the Event Viewer, particularly if you notice they've occured at the same time you get the blue screen (they're all timestamped in the Event Viewer).

 
Dirkdiggler2683 is absolutely right. FYI, the info he provided is availble right here in the
AT FAQs It's a good place to start any research on most issues 😉
 
OK...looking at the Event Viewer I'm seeing 2 consistent Stop errors. One is whats called a "Service Control
Manager" and the other says "acpi". What do I do with this info?

Thanks guys
 
Start be searching in the FAQ presented in the link from DAPUNISHER and look at the topic about disabling ACPI. After that see if the problem keeps happening or quits. If it quits you are good to go.

EDIT: Blah his faq link was not the one I was thinking it was. The following information is how to turn off ACPI. Pay close attention to the last paragraph. After turning that off, the computer will "refind" all your hardware and ask for drivers for it. ACPI is a driver that tries to use a single IRQ for all your devices. After turning that off, windows will see each device at a new IRQ and will then try to re-install the drivers for it.

* open up the control panel -> system -> device manager
* under the "computer" tree youll see a driver installed that
says "Advanced Configuration and Power Interface (ACPI) pc".
* open the properties of this and reinstall the driver from
the list as a "standard pc".

After the machine reboots youll find you need to reinstall all your video\sound drivers etc.
