PC Starts up and restarts, VGA LED on motherboard lit up

Hi all! My pc was working fine for the past 3 years or so without much of an issue except for a bad RAM. So I kept it for a while and decided to use it again after I came back from my semester break. As soon as I fire it up, it automatically restarted and now, the VGA LED on the motherboard is lit up constantly, resulting in a failure to perform a complete startup.

 

I have reseated my CPU and I don't think my ram is the issue since I just upgraded to some vengeance pros and it worked fine a week or so before this issue started.

 

I'm pretty much mesmerized right now and I don't have a clue which part of my rig is causing this. The PSU, GPU or motherboard? Hopefully I can still save it by swapping out faulty parts instead of purchasing new hardware to replace this old rig of mine.

Any suggestions are welcome ! :)

Yeah, VGA light. Edited the title.

My first build :) Well, unfortunately a few months after I got it, Sandy Bridge came out. Wasn't really following tech news by then.

reset the bios and try again...

Done resetting the bios and removing the battery, placing it back. No good, VGA led is still lit up.

UPDATES

Nothing is wrong with the power supply, checked it with a multimeter and there is power flowing through the PCIE 8 pin power connector.

It seems like this is no longer a variable :(

Which brings us to more costly replacements...no.....

Some of my buddies told me to check if there's power flowing through the pcie cables and as a matter of fact, there is current so I doubt the psu could bring a major issue. Fingers crossed thou.

Are there any other suggestions to which I could determine which part is faulty?

Id still try another PSU if you have access to one. Mine looked fine on a volt meter with all the rails where they needed to be but my comp still shut down at random times and failed to start on so e occasions.

Things like this can happen? I'll try and borrow a psu and do a quick check with it.

I'm currently using Corsair Vengeance Pro's and before this problem started, my rig worked perfectly fine. Went through 12 hours of stress test without issues. I did tried with my previous RAMs Corsair XMS 3 and still, the problem persists...

Thanks for the tip! And here's what I did :

1. I already checked with different PCIE slots yet it still fails to boot completely.

2. I checked the CPU socket and found no bent pins.
3. My CPU is a first generation Core I5 760 without IGPU so I'm unable to boot into the bios while using on-board graphics. So I'm not sure how I'm able to flash a new bios on it.

4. My connections are perfectly fine :)

If everything else is fine then checking the PSU would be next to try man.

I did checked the psu with a multimeter and current is flowing through every pin which makes sense (all live connections). I'm lost O.o

I had PSU issues with my 12, 5, and 3V rails all reading out normal. After replacing the PSU my machine has worked fine ever since. If you're having problems with the machine turning off or not starting swap the PSU and test it. Thank me later.

Guys, major milestone here :) My pc no longer restarts once I turned it on and it's able to stay alive until I cut the power. However, the VGA LED is still lit up.

Be wary of your PSU man. Just a word to the wise anytime you have power issues with it shutting down.
