screen flickers occasionally, shadows flicker

[sundrown]

Hello,

I just built a new PC for the first time a week ago. My components are:
CPU: i5 4590 3,3GHz
GPU: MSI R9 280 Gaming 3G
Motherboard: ASRock H87 Pro4
PSU: 400 Watt be quiet! Pure Power L8
RAM: 8GB Crucial Ballistix Sport DDR3-1600
SSD: 256GB Crucial MX100

Now the problem I have is that my screen flickers occasionally in League of Legends (the screen becomes white for a splitsecond). It occurs maybe once every session. I'm a little concerned with my GPU because I bought it from a less trusty shop. I already tried things like reinstalling drivers, using a vga cable instead of the hdmi cable i mostly use but it still occurs.

Edit:
My OS is Windows 8.1
I still dont know what's causing it, but using windowed mode makes flickering disappear in some cases.
Flashing the GPU didn't fix it.
Still occurs with a different monitor.

Also when running unigine, the shadows and some of the background flicker
with my cell phone.

Some of the r9 280/280x are pushed too far past their reference clock. This can cause flickering when jumping from 2d clocks-> 3d clocks.
I just fixed an XFX one that couldn't browse without flickering, flashed a bios onto it that had more vddc voltage.

This might be your problem.

Edit: Start by going to MSI website and finding bios updates if they have them.

Try testing on another monitor and if that doesn't solve the problem then roll back to integrated and see if you get problems there.

Unfortunately they have no bios updates on their websites. Should I try with one from here? http://www.techpowerup.com/vgabios/158292/msi-r9280-3072-140223.html
(tomshardware guide for updating gpu bios sent me there)

Check this guide out.
If you have integrated graphics you can usually reflash your video card even if you have a bad flash. In the guide he has a link to user submitted bioses. Make sure you backup your current bios before attemping any flashing. I recently did this, using this guide.
