So this has happened to me before where my monitor would just randomly black out, however in the past I've fixed it before by just reseating the graphics card and it was fixed until recently when I came back home and started playing SMITE. I have previously played SMITE and had no problem until I came home and suddenly it just blacked out. I figured that I could just reseat the graphics card. During the process of reseating it, I might have damaged the graphics card as I forgot how to release the pin holding my graphics card and struggled to take it out. I also might have damaged the motherboard by accidentally stabbing it with a screwdriver(thought I don't think it actually did any damage since it seems to be working fine and I have deemed the problem to be the graphics card's fault). So after I reseated my graphics card everything seemed to be fine, but it just blacked out on me again, the screen, but when it would black out I would hear excessive noise from the CPU area. So long story short I want to know your opinions on what the problem is.

I'm not tech savvy and my brother built/picked out my parts so I don't really know my parts that well but I'll try to provide some information regarding that area.

PSU: 600 watt (don't know the name)
Graphics card: Nvidia GeForce GTS 450
CPU Fan: It's from CoolMaster, that's all I know :|

Sorry about the super long post, it's my first time here, and the little information I could provide about my parts. Any advice or information regarding to any possible solutions are appreciated. :) 
I will also try my best to answer whatever additional questions that needs to be answered. Thank you for your time. :)

So does it black out while playing/browsing windows? If so, when it does black out try hitting Alt-Tab or the windows key on your keyboard.

Well to clarify my situation a bit more..... When I turn on my computer my computer screen would normally light up in an instant. If not it probably takes around 1-3 seconds, but for me right now it takes probably 5-10 seconds. Then it would go through the normal process but during the process, before it goes to the screen where you choose which account to go on if you have more than 1 on your computer, it blanks out and says "no signal" but after a while it proceeds to light back up and go to that screen I mentioned before. I would then choose my account but when it's loading my home screen it would take excessively long to load the icons and after a short while my screen with black out saying "no signal" and the CPU starts to get loud. So it has nothing to do with alt tabbing since seeing that I can't even load Google Chrome without having the monitor black out on me seconds later.

1. So either it's the Graphics Card that's the problem, which I think it is the problem, and I have to fix it somehow.

2. It's the motherboard, which I really doubt since it seems to be working fine unless I really damaged it when I stabbed it accidentally with a screwdriver. I can still turn off and on Num Lock so that's what led me to think it is not the problem.

3. The power supply is failing but I doubt it since it's 600 freakin' watts and it's a GTS450, which I am pretty sure is more than enough.

4. And my last couple of options are to bring it to a tech guy or wait for my brother to come home from college to try and take a look at my situation, but probably not getting one in the end.
