Lately when ive tried to play games my pc crashes. Usually i have no issues at all but lately i get about 30 minutes into playing a game and boom! my pc shuts down, although in a weird way. First my game will freeze, then my monitor will switch to power saving mode leaving me with no display, then short after my audio glitches out and becomes sometimes non-existant or just keeps making weird dialup like sounds. Anybody have any ideas what my problem could be?

One of three things

1) PSU Overheating or going over capacity
2) System overheating and becoming unstable (had plenty of that myself :D)
3) Faulty Components
4) Driver Issue.

I bet you didn't stability test when you overclocked your CPU at 4.5GHz. Set it to default clocks first and see how your system does. Also run a few passes of memtest to make sure that your memory is stable for more than the first few minutes.

Is there anyway to determine that my power supply is the issue before i start looking into purchasing a better one?

Some people recommend using a multimeter to test them, but you have to have some knowlege in working with them. There are testers that you can get, I have one that cmae with something I got. http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&DEPA=0&Order=BESTMATCH&Description=power+supply+tester&N=-1&isNodeId=1

When I first build and overclocked this pc i ran prime95 for hours to make sure it was stable with temperatures reaching no higher than 65 degrees, so i cant imagine the cpu is to blame. Although, I havent ran memtest before. I'll give that a go and see if my ram is faulty.

Alright, so i ran memtest from a bootable usb and the ram is stable, afterwards just becasue i was curious i cleared the CMOS to rule out that the overclocking wasnt the issue, and i can now say none of these things are contributing to the crashes becasue i just played some games again and still getting crashes. Its starting to look a lot like its the PSU that is at fault here. Dont suppose Rosewill would do anything to help me if the PSU is the issue?

Only if it is under warranty then you might get your money back. An exchange would be useless.

You should be good with something like this

CORSAIR Enthusiast Series TX850 V2 850W
http://www.newegg.com/Product/Product.aspx?Item=N82E16817139022

If you think you might need more power in the future it would be good to look into a higher rated 950W unit, though I don't see the 950TX on newegg right now or I'd recommend it :p. PC Power & Cooling as well as Antec are generally good choices

PC Power and Cooling Silencer Mk II 950W
http://www.newegg.com/Product/Product.aspx?Item=N82E16817703028

Whatever you decide on for a PSU make sure you search for relevant reviews on a specific model number. It's possible for a revision of the same model to be rather different in quality. You can also start researching PSU tiers and what not.

If you are running 7970's in Crossfire, than I can tell you that in addition to the Rosewill not being a very good PSU, there isn't enough on the rails to support that. This should do it as you have 62a on the rails which should be sufficient: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139030

By the way before you go and do all that make sure to test your cards individually. Disable crossfire and take one out, test it, and then do the same with the other. Assuming both work fine test with just one card in the second slot to make sure it isn't that slot on the motherboard. If the system works fine through all those tests then I would say you need a PSU. If not you may need to replace one of your cards or the motherboard.

I'm not running crossfire 7970's right now but im looking to get a second one in the future. So i should definitely upgrade to something more reliable before going crossfire.
