My pc suddenly won't boot. Before this happened, I experienced a BSOD. We all know that the most common cause of it is a hardware problem so I hurriedly opened my system to inspect. Here is the list of what I already did:

1. Check all power connectors(re-seated them, checked thoroughly). Boot for a few seconds then off

2. Remove the front panel connectors(Power,Power LED,HDD LED,Reset) and tried to manually boot it. No boot at all

3. Removed HDD Cables including power. Boot for a few seconds, then off

4. Re-seated all components except CPU. Boot for a few seconds then off

5. Removed the GFX, boot for a few seconds then off. Here's the shocking part, after a second try of booting. My PC turned on.

*NOTE:All "Boot for a few seconds" did not reach BIOS,Manufacturer Logo, etc just a black screen then off but the cpu and gfx fans are spinning the the power and hdd leds are on only for a few seconds

I still didn't believe that the GFX is the reason why my pc wont boot. So, I placed it back and the problem also went back. I tried removing and putting it back for a few times to see if the GFX is the real problem. But, every time that the GFX is present, my pc won't boot.
*GFX is Zotac GT610, it is already 3 months old(bought it last october) and I already used it for 3 months also but this problem just occured recently

Right now, I am using my pc through its onboard video(I removed my GFX of course). Now here's a funny part. Let's say the problem is my GFX. Now that I am using my onboard video(which is working,booting) there's this trick you need to do. The first try you turn on the switch, boot for a few seconds then off but the second try will success boot my system. In short, I need to push the power switch twice to successfully boot up my system.

I am planning to visit a computer store to inspect my system but before that, I need additional information on what should I do before I consult a computer technician just in case that I can repair it my self. Thank you

UPDATE:
Just went to a local shop and they have confirmed that the problem is the motheboard. Thank you very much for the efforts. Happy New Year :)
 
Definitely, the issue is related to the graphics card, but it might also be a faulty power supply.
Try clearing the CMOS (unplug the power cord and remove the CMOS battery for few minutes, or use the CMOS jumper).
If still the same, then you can test a different power supply at the local store.

Will try it later, I still need to gather more suggestions on what to do. Thanks


I only have 1 stick of memory, and both memory and cpu is not the problem because right now, the pc in my post is the pc that I am using while writing this but without its graphics card. I just still need more suggestions so that my GFX is out of my suspects list ahaha thanks :)

I just recently tried your suggestions but both of them did nothing to solve the problem. Thanks though :)



The problem is I don't have another PC haha but let me see if one of my friends would agree to let me use their computer for testing. Thanks :)

I am starting to think that the problem is my motherboard but I can't RMA it cause it's already too old(almost 10 yrs I think? haha). I am already looking for 2nd hand mobo to buy for testing purposes

I don't think that my RAM is the problem because I can use my pc right now but without a video card and I have to press the switch on button twice to successfully boot

UPDATE:
Now, I have to press the switch button three times but not only that, after 3x switch, boot then windows logo then off. Then the 4th switch will do the trick. My PC is playing math games with me -_- haha

And an internet friend of mine told me that he has experienced the same problem and suggested that I should reformat my HDD since that what he did also, gonna find it out soon. Don't want to format it right away
