Actually I cant run my computer without my GPU coz my motherboard (Asus Sabertooth x79) has no VGA, DVI or HDMI slots in in. I'll try to swap video cards with my friend to test it on our computers. I'll put his video card in my pc and he'll try my video card in his pc and i'll keep this thread updated. Thank you so much for the replies!
I bought a new graphics card which is an Asus Nvidia GTX 660 TI. Then after I put it in my computer and installed the latest driver which is v306.97, my computer randomly freezes. Like when I watched youtube videos in full screen(happened 2 times), when I was on facebook(happened once), when I was using photoshop(happened once), about to play Dota 2(happens 9 out of 10 times whenever I'll try playing it)and with some other games and even when I was idle.
Here's my specs:
OS: Windows 7 Ultimate 64bit
Motherboard: Asus Sabertooth x79
Ram: 32gb(quad) ddr3 G.skill ares
Processor:Intel Core i7 3930K LGA2011
Graphics Card: Asus Nvidia GTX 660 TI
PSU: Thermaltak TT Toughpower modular 1200 watts
Im really getting frustrated with this, please help me. I'll really appreciate it.
