I need to know the cause of Pixelated Screen Issue

[kevin_2015]

Hi would just like to ask help,

I recently encountered an Issue with my PC display.

While playing Dota 2 in my PC I encountered a Pixelated screen and it freezes my PC, So I restarted it and It goes back to normal.Sometimes I encountered blue screen. From what I know it might be damage on my video card, I just dont know whats the cause of it.

I do have a monitoring sofware "MSI Afterburner" for monitoring temperature of my PC so that I would know if its overheating and I think temperature is nomal.

CPU: 55 - 60 degree celcius
GPU1: 50 - 60 degree celcius
GPU2: 50 - 60 degree celcius

Heres my PC Specifications:

MOBO: Gigabyte z87 D3HP
Processor: i5-4570
CPU Heatsink: Cooler Master Hyper 212X
Video Card: 2x Sapphire r9 -270x Dual 2GB DDR5 (Crossfire Enabled)
System Fan Connected to MOBO: Bitfenix 1 X 220 mm, 1 x 120mm, 3 x 140mm
Monitor: 1 x Asus VX239
Power Supply: Aerocool X-strike 600 watts,

Appreciate your help

Thanks!!

You have two video cards, remove one and test it, see if both work fine on their own or not.

CPU is on the warm side, GPUs are on the cool side. Do you have any case fans in your case or just the CPU heatsink fan? Does the lock happen in any other game?
