I'm at my wits' end here.

Hello, lovely citizens of Tom's Hardware. I appear to have run into a slight (and by 'slight', I mean monumental) problem with my desktop PC. Today has been a very tiresome day, to say the least, and this little issue is the proverbial cherry on top of this <insert foul word here>-sundae.
Earlier this morning, I took my graphics cards out for routine maintenance, namely reapplying the thermal paste to only one of them, as I had dangerously high temperatures (up to 102°C, even with a custom fan profile and an external fan blowing cool air at the case) and it was a good thing I did, as there were gobs and mounds of the stuff all over the place, to which I carefully cleaned and reapplied some better quality paste. I plug everything back in, and everything is hunky-dorey. Then, fast forward about 2 hours, I hear clicking coming from one of the cards. After investigating, I find that one of the fans on the card that I did nothing more than blow air through had stopped spinning. The cause? Two fan blades had come loose. I shut down the computer, remove the cards again, and learn that after that incident, there were another 3 blades on the card I applies thermal paste to had come loose in the same fashion. The motors on both of the fans are perfectly fine and undamaged, so I proceeded to reinstall the cards after dealing with the rogue fan blades. It was then when I decided to install the old RAM I had saved when I got a new 8gb stick, to which the computer began to act very strangely. It would make it to POST, the computer beeps as it always did, but there was a problem. There was no video output. After searching around for a bit, I was unable to come to a solution. I used both the card that I disassembled and the one that I left untouched as a source for video output, neither worked. I tried using only one card. Neither worked. I tried using a different monitor. Still didn't get a signal. I checked where it plugs into my monitor. That plug is fine. As I began typing this thread up, I had my headphones on for no real reason, and I heard the Windows Login jingle. So whatever was going on, the computer seems fine; just no video output. So as of right now, I believe that I am sitting at the desktop, just without any video. My friend has confirmed that I am online on Steam. Can anyone offer any tips? Kinda desperate at this point.

P.S. I have also tried using an old GTS 450 I had lying around, which also does not get any signal.


UPDATE! I'm not sure how or why, but after resetting my time to be correct, SSL errors have disappeared, and I can see images on any webpage. Everything is back up and running. Thanks for helping; this whole day has been a giant fustercluck that didn't throw any punches. Now I just need to figure out how to make this HDMI cable not look so... ugly.
 
"...as there were gobs and mounds of the stuff all over the place..." It's been a long day. Take a break. I suggest looking at it in the morning with a fresh start. It sounds like there's something simple you overlooked. Start fresh and walk through the entire procedure again slowly and make sure you do the maintenance on the rest of the box as well. The reason I mention the "gobs and mounds" is so you'll clean the case, mobo, etc. Maybe even between the mobo and case and inside the slot connectors with canned air. It really does sound like you are looking at the problem and just not seeing it.
 


I have. However, bit of an update on the situation. I was finally able to get a signal from the computer, however, it was blank, and was the wrong resolution. I tried switching to an HDMI cable, which works fine. 1080p, full video, the works. However, I still think that there is something wrong. After finally getting a picture to my monitor, I see that there are a bunch of icons missing from my taskbar. Things such as the connection meter, action center, and other Windows processes are there, but not clickable or visible. A screenshot of what I mean: http://puu.sh/9eb14/81e3c1d000.jpg

Google Chrome also appears to be acting strangely. Whenever I try to access any website made by Google, be it YouTube, Google search, Gmail, Google+, anything. A screenshot of trying to access my Email: http://puu.sh/9eb9O/cd889198d5.png

Almost all pictures from any webpage are showing either nothing, or a broken image symbol. An example of teamfortress.com: http://puu.sh/9ebgu/d02ab213d1.png

Could I be infected with something? I ran a malware scan, which turned up empty, but I'm not sure. Will try rebooting and will update with how that turns out.
