I got a computer for free because it was running vista with a sata 3 HDD and the guy said it was running slow.

I decided I was going to make it a PC for my office room since all I do in there is type with word, some excel, and web browsing. The PC was fine before but it was slow, so I had a SSD laying around and I removed the HDD cage and DVD cage from the computer since I wanted the computer to be very light and mobile and I was just gonna use some double sided tape to stick the SSD in.

Well I install the SSD and install windows 10 and everything is fine. I shut down the computer then opened the case and I sprayed it out with canned air and I removed the CPU heatsink and reapplied some thermal paste since that the thermal paste was dried out and old, I used 91% rubbing alcohol and applied some Arctic MX 4 thermal paste cause I have used it in many PC's I've built in the past. I screwed the heatsink back on and closed the case.

When I plugged everything back in, the PC turns on but now the monitor shows no display. I tested my VGA cable and monitor on another PC and they work fine. I moved the ram to different spots and tried using only one stick of ram, I removed the cmos battery, unplugged everything from the mobo and replugged it, made sure everything was connected tightly. Everything. I removed the cpu to see if I might have bent some pins on it but everything seems fine. The PC only has one output port and it's VGA.
Any help would be appreciated, thanks!
