Hello all, This is a weird problem that I have for a couple of days now and I cannot figure out why. About 3 days ago, my computer was running fine after a reformat. About two days afterward, I decided to borrowed some of my friend's arctic silver 5 compound because computer temperature seemed to be high. After applying a decent amount of thermal compound on top of the CPU and under the heatsink as well, I put the heatsink back in. So then I turned on the computer, however, the computer starts up fine with all case fans running including the one on the graphics card. But there is one problem. My monitor kept saying no input as there is no signal coming from the graphics card. To troubleshoot, I rewired everything and made sure everything was seated properly yet to no avail. I came to the conclusion that I either fried my CPU or my motherboard is dead somehow. I have an old Intel computer at home also but it's so old that it doesn't have an AGP slot where I can test my gfx card. Please help me as I am very frustrated and don't know what to do. Thank you in advance for your help.
