Have a very confusing situation. I took my windows 7 desktop out of sleep mode and there was no signal to my monitor. I checked the monitor and hdmi cable, they are fine. I attached a vga cable to the motherboard's regular graphic port and it worked. However, when i got into windows it said that it wasnt a genuine copy. I thought maybe it is some kind of virus so i reinstalled windows hoping it would fix the video card, it didnt and windows would crash after ten or so minutes so it was hard to set it up. I finally got the drivers for the video card loaded but the computer didnt recognize the card. I switched the video card to the other port cause i have two on my asus motherboard. It worked, so i switched back to the hdmi cable from the video card to my monitor. I thought that everything would be fixed now, but nope. The computer keeps crashing every few minutes. sometimes doesnt make it more than 30 seconds into windows. I checked the ram and did a memtest86 and it seemed to pass. I switched the ram to the other two ram ports and still crashing. I did a test on the hard drive and it is functioning normally. Does this all add up to the motherboard failing? I think it might be shorting somewhere or something, but dont know how to find it. Could the CPU be failing. I have only had the comp for 2 years and have never had any problems. I am pretty confused, but i am pretty sure that my video card, Hard drive, and ram work. Its an i7 processor, an hd7850 video card, asus p8b75-v motherboard, and g-skill sniper ddr3 ram, 2 4g chips. If anyone has any idea why this happened, please let me know. Im stumped.
