Old 3rd gen Core i5 based system won't POST

[azX_]

General System Configuration

Intel Core i5 3470 (no overclocks)

Kingston HyperX Fury 8GB DDR3

ASUS P8Z77-M

Troubleshooting methods done

1. Removing the RAM.

    Result : It powers on, no video and no memOK light.

 

2. Using different power supplies.

    Results : Again, powers on, no video and no memOK light.

 

3. Reseating the CPU.

    Results: see above.

 

4. removing the CMOS battery to reset to defaults 

    Results: see above.

 

Additional information

this system was built on 2013, stopped working since last year due to a dead GPU. Multiple technicians recommended a power supply swap or motherboard swap. My friend didn't go with either.

He sent it to me, the original power supply is healthy, ram is also in working condition. It booted up previously, with memOK lights and able to boot to BIOS, however, after inserting the board into the case, it didn't boot up. removed the board from the case, sat it on a box and troubleshoot it again, results are no memOK lights, and just able to power on with no video.

So what happens when you add a graphics card? Still the same? While rare, the onboard graphics could also be defective/disabled despite CMOS resets.

I would try all the possible video outs, and make sure one of them didn't die. Also, if possible test all the components in a different board.

added a graphics card, still the same result, all video outs tested.

all the components except the CPU has been tested, will try the 3470 on the h61 board

Good idea, but beware of a small catch: if that H61 board has never been updated in its life, it might not boot with the 3470. For 100% certainty, you'll need a sandy bridge CPU.

Wait so the problem came when you put the MoBo in the case? As when you take it out and test it you get a POST? Even with the GPU in? If that’s so, then there is something shorting the motherboard in the case. Check for spare metal or bents pieces. Maybe a crooked stand off or something stuck to the back of the motherboard

Don't H61 boards need a bios update to work with Ivy Bridge cpu's?

the board in question has been updated so no need to worry

 

i'm gonna try reading the manual if memOK lights should light up if no dimms are installed

yes, but when i removed it from the case, it still is the same

 

anyways, i tried a different processor, a core i5 3330 and it still wont post.
