Clean your memory pins with a white eraser, make sure there's no dust in the memory slot.

Also, did you remember to plug your cpu fan?
I did that before but that does not seem to be a problem because when there are these issues it kind of give 2-3 beep morse code or very long beep

Well, it doens't say anything about hardware damage in that screen. Does your sata cable is well connected to the motherboard, the hdd and the psu?

You also may need to reinstall your windows.

Yes they are I just checked but I noticed one other thing while booting this time that clock was changed to 1.3ghz from 3.20 ghz(3.20ghz was when system was alright). About Windows reinstallation, it can't enter setup it ends up with same problem.

Take your processor out of the socket and look if you didn't bent any pins.

No there aren't but do processor fan have to do with any change of clock speed ,it seems to be misbehaving ,but Im not all sure.
Can you post a picture of inside your case? just so we can look if all the cables are properly connected.

Put some pressure into all cables, make sure they are well plugged in.

It could be either your memory stick or your HDD, you'll need to try both at another computer.

This might be silly, but i had a similar problem once when i didn't plugged my psu power cord well enough.
