Computer does not boot and no beep but fans run start and stop continuously

Today evening i turned on my system just to see that System was not booting but i could see cpu fans was running / rotating normally and dvd /cd drive was flickering it was ejecting and closing normally, though i switched off the main powersupply and try to power on many times the result was same only fans was running which stopped and rotated with 3 -4 seconds of interval but i was not able to hear beep and not entering bios, Beep indicates that all hardware components are ok, but i remember last time i used the computer i heard a strange long beep twice but the shutdown happened successfully my system is 6 years old intel pentium 2.4gHz , 1GB RAM, 80GB hdd, ASRock P4i45 Motherboard 845GV pretty legacy system :) but very much fine for browsing, playing games and other entertainment and daily use stuff.

And after lot of surfing i came to know few possibilities why it happens below are some:

1. This happens if your PSU is failed, without proper powersupply to motherboard system does not power up and enters boot sequence

2. Graphic card driver or one of your sister card driver might be corrupted or not properly fitted.

3. Try to remove all the power and pcb cords and reconnect so that its not the case of loose connection

4. Do the CMOS clear/reset and Switch of the powersupply and remove CMOS battery for a while and put it back, though CMOS battery is just to keep ticking of clock when system is shutdown and powersupply is removed.

5. It could be the case of faulty Memory Stick or dust between the RAM terminals, just blow any dust from Memory slots and clean the terminal contacts gently removing any dust and refit, if it does't help try Swapping RAM from your friends.

In my case the problem got fixed by removing memory sticks / ram cleaning its terminal blowing compressed air in the slots to remove dust and putting back the RAM, now system is booting properly though i did all the above mentioned things before, it got booted properly when i cleaned the RAM but i am not damn sure because of which above points the system started workin properly if any hardware guy reading this please penn in your comments.

Thank you for your help in talking about this. Nice review! Also turn your attention that it needs to search for software development companies if you need development mobile.
