Hello. I play games on steam. When I play games for like 5 or 10 minutes, steam games just freezes, then a striped lines appears on my screen. There are lots of colors. The colors change depending on the color of the game. After getting the striped lines, I would sometimes just crash, get a bluescreen, then restart. but sometimes it would just freeze or a second, screen goes black then to the game screen and can play again. Before getting the striped lines, the game would run normally and smoothly like it should.
It only happens on steam. When I play other non-steam games, it wont get the striped lines, but when ever i add the games to steam with the 'add non-steam games' button, it would give me the striped lines.
Sometimes, when i play non steam games, without steam, it would the screen would go black and crash, and say The Graphics card has stopped working and fixed blah blah blah or somehting like that.
When I change the screen resolution for some games, the screen goes black and shows the desktop only on the 1/5 of the screen on the right. it would just blink. It shows the desktop, then goes black, show the desktop, then goes back. I dont know what to do. I cant do anything then except ctrl+alt+delete thing.
My Specs are:
CPU: AMD Athlon II X3 450 3.20GHz
GPU: AMD Radeon HD 6670
Operationg System: Windows 7 Home Premium 64 Bit
Power Supply: 250w (I don't know the brand. It's from HP p6604f. I just upgraded CPU and GPU on that computer.)
I was gonna say, The only time I have seen 124's are from too much overclocking
i dont think i over clocked it, because i dont know how to do it, and i heard it is very risky. I got the CPU very recently btw. like 3 days ago. i upgraded to it from Athlon II X2 420 because of the problem.
