I woke up this morning and turned on my pc, it shut off after about 2 seconds, I looked over to see what the heck was going on and I saw smoke coming out of it! I opened her up and I saw that it started at the connection point of one of my video cards. So I took that video card out and decided "Oh well, I'll just use one video card then" and tried to run it that way but unfortunately my computer simply will not run... Now my question is could the issue be my power supply or could I have messed up my motherboard? The PCI express port on my motherboard is slightly chard but it doesn't seem to be damaged at all beyond the port itself. The reason why I think my power supply could possibly be an issue is because when I run power to my pc no lights come on what-so-ever except for one light that flashes every 5 seconds or so, which used to be on steadily. Thanks in advance for any suggestions or advice.
