Computer crashing while playing games

[supernovaqq]

Hello guys, I am relatively new to building my own computer and this is the first one I have ever built. My computer keeps crashing while playing any games that go full screen, be it League of Legends, CS:GO, BF3, they all crash. Sometimes, it will run for as long as I need and not crash, but usually, it crashes very quickly (5 Minutes) or in the middle of me doing something (30-1H) . When this happens it either crashes to a black screen and I get no signal or it crashes to a colored screen with lines running down the screen. I have to hard restart my computer to be able to use it again. Also, I do not get the post beeps when my computer starts up. My computer runs fine and never has a problem watching videos or surfing the web but as soon as I get into a game after a couple minutes it crashes. I have tried re installing windows, re installing the video drivers, cleaned out my computer, everything! I don't think this is overheating but it may be, I have hardware monitor and my temps are all >40 idle and >60-65 under load. After when my computer crashes sometimes I get three beeps from my computer so I think it may be a hardware problem if it is not overheating. I have been looking for a solution but nothing is working! Please help!

Note: I have NO overclocks of ANY type running at all at the moment. All clock speeds are running at default settings

Specs:
Mobo: Asrock z77 extreme 4
GPU: Gigabyte 7850 OC edition
CPU: i3-2120
Power Supply: Antec Neo 520W

Computer Idle Temps:

CPU Temps Under Load: (Intel Burn Test 10 passes)

GPU Temps Under Load (FurMark 1080P Burn in test, Max temp 82C 15 mins)

My GPU got quite hot, but not enough to crash so I don't think it's that, the only think I can think of left is the mobo

This is a crosspost from newbuild because most people are saying it is a GPU related issue. I am on integrated graphics right now because someone suggested to try that. I don't think it is the GPU but I am new to PC building so I am probably wrong.

If you have any advice or need any more information about my rig please post below and i will try to the best of my ability to do whatever you ask.

The thing is, you guys were saying it was a graphics issue and I assumed people who specialize in graphics issues would be better suited for answer how to fix them.

installed drivers off disc.( disc that came with motherboard.) went to windows update and installed the netframework........ and other stuff that might be there ? latest DX......... when you installed the games did they ask to install DX. some games won't work right without the Dx that's on the game disc. what's in the device manager that has an ? next to it.

I had a similar problem many years ago it turned out my Power supply unit wasn't powerful enough at that time and had to upgrade it. That GPU you have is a grunty card and could be drawing too much power from the PSU and causing your computer to crash. I don't know all the components you have in your build but I'm an Asus fan and they have a website for power recommendations:-

In my current system I have a 650 watt PSU along with a 5750 GPU and with all my components it needs at least 500watt.



Hope this helps!
