Ram Speed, size and #sticks: 8Gb total, 2 sticks of 4gb Kingston

Attached is the saved text file from Bluescreenviewer, usually I crash when playing games like TF2. It has never crashed from casual web surfing, and only started about 3 weeks ago. I was playing TF2 for about 4 hours earlier and it either BSODed with said info in the textfile, or froze while my game sounds stuttered.

I also realize that my psu may be a little underpowered for my current setup, but I can assure you ever since I upgraded my computer, it has not given me any problems.

Actions taken so far: Chkdsk, disk cleanup, advancedsystemcare cleanup

Temp while idle: 39c
Temp while gaming: 65

Im not too sure what else to add, I'll be back here later when it BSODs. Thanks guys for taking a look!

Yes, swap out that CoolerMaster power supply, for a better brand

Okay, I'm considering getting a new one, but why would my PC work properly earlier and only act up now? Also, do you have any brand recommendations for wattage needs?

 

[Tmagic650]

Because that power supply has probably degraded over time quicker than a better brand supply. All power supplies will fail after a lot of use. Corsair, Antec, Thermaltake 650 or so watts. Here's an example:
