I just cleaned PC (well CPU fan only), and i turned PC on but forget to insert CPU 4 pin wire (not the first time). Unpluged PC from electiricty. I inserted it and turned on PC, then the CPU cooler started to spin like crazy. Windows loaded and cooler started to work normally but motherboard temperature was 60 C. I restarted the PC to check BIOS settings, but the screen was black, no beeps, hard disk were spinning as if there were loading windows, i tried to reset BIOS setting but no affect just black screen. DId i damaged the motherboard. I forget that i was playing minecraft on built in graphics card (20 - 30 fps, yes i know bad, but i wanted to play so much). Maybe video card is dead?? please help! Specs that I remember:

Motherboard: HP P4SD
CPU Intel Pentium 4 2.80 GHZ
Ram 1.5 GB DDR, (1 GB + 256 MB + 256 MB) - Kingston
Built-in video card: Intel (R) 82865g

Edit
I have re-seated the RAM but look what happened:

Judging by that picture, the fact you're using an integrated video adapter, and your remarks about sticks of RAM not working, I'd say you have bad RAM.

Get Memtest86+ (or another competent RAM tester) and run it against the RAM sticks, one at a time, for many hours (we do 48 hours of testing before declaring a RAM module as "passed").

This should help you identify which stick(s) are bad. If they come up clean after 48 hours on each stick, then I think you'd be at a point where you need to start swapping in known-good parts to find the culprit (RAM modules, motherboard, PSU, etc.).

When you cleaned out your PC you could've had some dust moved in critical areas, take another look at it and make sure there's no dust or anything trapped in the PCB of the motherboard, also try and locate where the integrated Graphics is, if you provide the model of your motherboard I can help further. Not putting your CPU Fan wire in could have caused the CPU to heat up but shouldn't have caused any damage since the heatsink was placed on top.

What I would suggest your do is give it another once over.
