My computer has recently been crashing and upon happening the screen glitches into green and pink colors. After some time I'm either some times able to save my PC from crashing by pressing CTRL + ALT + DEL or it glitches out even more showing partly a black a screen. I've tried switching out my monitor and hdmi cable. I'm looking to find out why this is happening as this is a brand new PC I paid around $1000 for.
