PC refuses to work please help

andreww416 · Feb 9, 2018

Okay so I'm pretty much in a constant battle with my pc maybe you guys can help. So my computer randomly turned off. Alright? So I switch psu. Still doesn't startup so I change motherboard and cpu. I finally think the problem is solved, but no, it still doesn't start up. I would like to add that the lights on the fans do flash before it goes right back off. Before I gave up on the motherboard I tried a cmos reset on the new psu. I feel like if there was an issue with gpu or my 1 tb ssd that wouldn't matter, and my computer wouldn't do what it's been doing.

Original specs:
Msi-gaming 5
Intel i7-4790s
Geforce gtx 1080 ti
Corsair h60 120mm cpu cooling
Amd r9-radeon 290x
750w seasonic x-series
32 gb ripjaws ddr3 ram

Changes:
ASRock AB350 gaming k4
Amd a8-8400
4 GB ram (not sure which brand)
EVGA 850 supernova G2

Why would you swap out a good CPU for a crap one?
Why did you used to use both a 1080ti and a 290x?

I have not heard of an A8 8400. Are you sure you do not mean the i5 8400? The 4 GB brand which you have, you are not mixing it with another RAM right? And they are DDR4?

I use it on the side for mining so I have 2 gpus. Also, I swapped out the cpu because the motherboard I got had an amd chipset. I just figured I didn't want to take chances of a faulty main part being damaged.

If you changed from Intel to AMD did you do a clean install?

That Amd a8-8400 isnt listed as a supported CPU for that mobo

The only A8 thats listed is this one. If this is the mobo

AM4 A8 A8-9600(AD9600AGM44AB) 65W Bristol Ridge 3.1GHz 2MB A1 All

ArchitSahu :

I think the entire post is a troll. There was a amd a8 series. The listed MB is an AMD chipset MB.

My bad not 8400, and a8-9600

Paul NZ · Feb 9, 2018

Remove the GPU. Looks like that CPU has integrated gfx

If you get a display, you'll have to do a clean install

andreww416 · Feb 9, 2018

I've tried unplugging both gpus at one point and the ssd at one point.

andreww416 · Feb 9, 2018

Biggest issue is that I can't turn it on no matter what

Paul NZ · Feb 9, 2018

Did you connect the 24 pin cpu fan and the 4/8 pin ATX12 connector?

andreww416 · Feb 9, 2018

Yup, made sure of it multiple times to make sure it wasn't a loose cable or anything silly. I'm beginning to think it could be the hard drive because that's the one thing I didn't attempt to switch. But the main reason i suspect this is because it shut down permanently after i tried to do a system backup

Paul NZ · Feb 9, 2018

The hdd has nothing to do with it, if it wont turn on.

But when and if it does, you'll have to do a clean install if the hdd has an OS on it from something else

I would get a mobo speaker and see how many beeps you get

andreww416 · Feb 9, 2018

Well I'm about 100% sure that it can't be the psu, mobo, cpu, or ram. I suspect that it could miscommunication between parts

andreww416 · Feb 9, 2018

If you think about it, the ssd could cause it if it's not functioning properly just as well as any part, the best way to test it could just be finding an old hard drive lying around and plug that in.

Paul NZ · Feb 9, 2018

Unplug it. All you need is the cpu, ram and make sure the above cables are in properly

andreww416 · Feb 9, 2018

Thanks for all the help I'll try this all when I get home. I should've probably waited until I was home to post this thread, I'll post a reply if it works.

andreww416 · Feb 9, 2018

Bad sata cable, thanks a lot.
