I'm not positive what's causing my computer to be stuck in a boot loop where it turns on all the fans for about 2 seconds before restarting, but I do think I screwed up a couple of things and was wondering if that is the cause of it. I tried putting in a new cpu fan on my old computer and ended up getting thermal grease into the motherboard which I think was causing my first boot loop. I had a warranty on my mobo though so I switched it out to try again. Same problem and when I look at the processor, it had some thermal grease on it that might have been from the previous motherboard when it was on there. I tried cleaning it off with some alchohol and placing it back in the new motherboard, but still no luck.
The problem is that I had an older processor that I haven't used in a couple of months and tried it in there as well with no luck. I'm not positive that its still working without issues though, so its possible that the older processor just doesn't work from a separate issue.
So is it possible that the thermal grease on the bottom of my cpu (where it connects to the mobo's pins) is causing these problems for me? Or did I just have the unfortunate luck of either getting a bad replacement board or breaking it somehow in my installation. And is there anything I can do to try and fix it? I can replace the motherboard easily, but the processors are a bit more of a hassle, so I'm really hoping that it shouldn't be an issue.
