Whoever fixes this problem gets my money

Okay, so to start off

 

I have a pre-built PC that my parents bought for me 4 years ago (2012-2013), which was decent for that time and it worked PERFECTLY, specs back then were:

 

i5 3350P

Nvidia GT 630 2GB

330W HP PSU

1 TB HDD

6 GB Generic Ram (Hyundai RAM)

Windows 7 (not that it matters)

 

Anyway, so for a long time I didn't bother with upgrading any components but around mid 2016 I realized that I couldn't even run modern titles on Low settings without having frame drops to low 20s

which was very annoying, so fast forward a few months of saving up (and some lucky bonuses) I finally updated my build to:

 

i5 3350P (same processor, I didn't change it)

ASUS Nvidia GTX970 Strix OC

16 GB HyperX Fury Ram

2 TB HDD

Corsair VS650 (650W PSU)

Windows 10

 

 

Motherboard is: FOXCONN 2ADA with H61 Chipset (for those who are wondering)

 

 

BUT!, soon after updating the build my PC started to have a problem, it would just decide to not POST randomly.

at first I thought I must've done something wrong with the connections or maybe the RAM isn't compatible or the GFX card.

 

I tried putting back all the components that I had replaced back on the motherboard and tried again but that problem still persisted.

Sometimes it would POST (lights turned on and HDD spinning, GFX fans spin etc but no output on the monitor) , but sometimes it would not. Completely randomly.

 

I tried the new component with my friend's build and they worked completely fine with no problem whatsoever, posted each time I turned it on. But my motherboard won't post at times, regardless of what components from the bunch I was using.

 

Here are the fixes that I have tried that have worked OCCASIONALLY:

 

 1) CMOS Clear

 2) Complete dedusting of the components

 3) Replacing CMOS battery

 4) Total teardown of the build and rebuilding it

 5) Letting the PC turned off overnight completely unplugged

 6) Leaving the PC open (turned on but no POST) overnight

 7) Trying a new PC Case

 8) Unplugging a one of the two HDD

 9) Unplugging the CD Drive (I know what you all are thinking, but come on, it was a pre-build system I didn't intentionally install it)

10) Unplugging Keyboard/Mouse/Headphones/Printer (Basically all USB connections) and restarting

11) Prayed to God to please make it work 

12) Tried just restarting it

 

 

These fixes worked at max once or twice, they DID NOT work everytime, heck the last one only worked ONCE in the last 2 months.

 

TL;DR: PC wont post after hardware upgrades, no matter what, randomly decides to post when it wants to.

 

I have tried every Google search result on the first two pages, and none of them helped. My only option is to leave it open once it POSTS and just shut off the monitor/lock my pc when not in use.

 

My guess is maybe the Motherboard wasn't getting enough power to supply to all components at the same time, but a 650W PSU should be more than enough, but I really don't know anymore.

 

Thanks!

You forgot the case...

[Schakal_No1]

my guess is that either one of your new components has a defect or you damaged your motherboard in the upgrade process.

Lets pretend its the best one.

Some old mobo have PCI power limits. 25W if I not mistaken.

The PSU may not be able to deliver full power to the GPU since it's a Corsair VS which is not that great.

Also you may damage the components while swapping out them due to static electricity.

yeah but if the motherboard was damaged wouldn't it not POST at all? because it turns on, and if it feels like it, it posts, otherwise it just sits there doing nothing but spin fans

Let's not. Some cases have a known issue with leads being easily broken and the fix could simply be a case of resoldering or recapping.

The case is completely fine, I checked all connections, I even tried it with a new case just to be sure, it worked but even in the new case the problem was still there, so im 100% sure the case is not at fault

How are the capacitors on the motherboard?

Specifically the ones around the cpu.

Hmmm, but then shouldn't it not power it at all? if the drawn power is over the PCI power limit.

it does posts randomly, and when it does it worked completely fine, it even overclocks (the gfx) and works great without any issues

in perfect shape, not wobbly or the solder is not broken, also no liquid on them or around them or anywhere near them. everything is in perfect condition from the looks of it.

But they're perfectly flat? All of them.

All the ones that I can see, yes. all of them. flat and perfect fit.

[Schakal_No1]

can you try to use your old RAM? A RAM defect could have such an effect.

Not at all. My friend has the same situation. His GPU exceeds the PCI power limit. Still can use but performance degraded.

Are you capable of turning it on with a screwdriver? You know to do it? Try it please if you know how to properly do it

[WereCat]

Are you sure that the issue is not that VS series PSU?

I see, but my 970 performs on par with the results online, and sometimes even fits in extra FPS, so I have no GFX performance issues AT ALL.

Short the power pins? yeah I've tried it, same problem, sometimes posts, sometimes it doesnt

Have you updated bios?

[cron.7]

Whatch out for 

1. Bent pins
2. burned Capacitors or Resistors (Mobo,GPU)
3. try another PSU

I did try that, it worked once, then the same problem again, like I said, swapping old and new components did not have any improvements.

Tried all 3. no improvement or change. 

[genexis_x]

It could be the mobo problem. Maybe it's dying.

I'm on the latest one for my motherboard (which was released in around 2013)
