Hi I have recently been going through the process of upgrading my computer and what is currently in it is

Asus M5A78L-M LX V2 ( I am aware this is a bad board it will be upgraded too)
AMD Athlon II X4 640
Thermaltake smart power 650W
Gigabyte r9-280x
2x 4 gigabyte sticks G.skill ram

The problems I have been having are shutdowns and flickering.

the other week I bought a mini display to hdmi adapter to connect my TV up as a second monitor and for this first few days this worked fine but then when the TV was turned on my main monitor would go blank but the TV would have the extended display. I tried the other display port and it was fine.

A few days after that when I booted up my system in the morning it said short circuit protection had come on. once removed it is fine but basically when the cable is in it sometimes works and sometimes just shuts off to surge protection.

Just last night after doing this I turned off the TV and was using just my main monitor and the screen flickered like crazy. It went up and down and made it unwatchable. I checked loose cables and unplugged and re-plugged them but it still flickered. Today it has been fine and not skipped a beat. I want to know if it is my cheap mobo or maybe I got a faulty unit elsewhere?

Thank you to anyone who can reply :)

so if you start a furmark and a prime95 at the same time it should start flickering. which if true... means it's either the psu or the motherboard, only way to decide between them really is by getting a new one to test with, good news: cpu, ram and gpu seem ok.

Hi thanks for the quick reply and yeah temps are fine nothing getting too hot and I also checked inside if anything was loose and everything was fine , I kinda think that it could be this motherboard which is supposed to be very low in quality , I may do a clean reinstall of drivers if it comes to it.

it's hard to decide really, to be sure you'd need to take each component and test it in another pc that you know works ok and if all check out ok it has to be the motherboard... i assumed a psu/gpu because the end result was a monitor problem, motherboard/ram/cpu issues normally would end up with a blue screen/no post/no windows loading,

can you run a prime95 and/or memtest? to stress out the cpu/ram assembly?

I ran a prime95 test for 30 minutes and everything was alright , cpu temps hovered around 60 degrees if thats of any use.

I just ran a furmark test for like 45 minutes >.> then realized there was a 15 minute benchmark option so after that I got these results.

1920x1080p 0 AA
fps min:11 fps max:31 fps avg:20
Temps were 60-80 but on average were about 65 - 70C.

I just ran both tests for 15 minutes and there was no flicker but i did drop frames a bit more , instead of upgrading my processor straight away I think ill buy a new mobo first instead and see how it all goes then. Thanks alot for you help! much appreciated! :)
