I don't know why my PC isn't working

[ewoutbaars]

I got a PC but it's displaying no video. with no intergraded graphics there are no post codes, speaker is connected my CPU is spinning my gpu fan is not if I remove CPU fan from header still no beeps. Hdd is spinning it keeps running and doesn't shutdown after a short while. I am using a and fx CPU en HD 7750 powercolor2 gpu motherboard is a msi 970a-g46

I think speaker is probably dead and gpu and CPU but I don't know when I boot up 4 blue led light up very short and the go off
DVD eject works reset work's
Hdd got no is on it .
This all happened after a close reset.

Um...do not remove fan from the cpu heat sink. That's recipe for melting it down.
If the cpu fan is spinning but not the gpu fan, and you've got no integrated graphics, then naturally you'll get no image. I'd take it into the shop so they can fit in another gpu to confirm everything else is working, and then you can decide on what gpu you want to get because what you have is likely dead.
Not sure where the blue lights are that you speak of. On the mobo? From https://www.msi.com/Motherboard/support/970A-G46#down-manual
which would mean your cpu is in 4 phase power mode meaning likely your cpu is ok. Just get it checked and they'll likely have a gpu you can replace yours with that will work.

I got a spare gpu in a higher end system of me I can put it in that system to check but is there a change that if I put my gpu in the not working PC it brakes ? Because I don't want it to break. I am very care full with that gpu. And PC shops are not near me and I don't have driver license. Sorry for bad English I am dutch btw I was under locking CPU because it was running hot then cmos reset.

It has worked before

 

[rgd1101]

Ok, old system, work before, try another working psu? or another working gpu(don't put anything high end, it won't support them)?

I got a GTX 9604gb msi is that going to work? And if it's going to work is there a chance it might break my gpu?

Normally it should be ok. If your psu is dying though, and killed off your gpu after a while, it might not sound like the greatest idea to put in a new gpu but that kind of damage tends to build up over time, it's not instantaneous. Also if it was your psu I would have expected you to see performance issues over time, as well as critical errors, shutdowns and so on, before it just gave up on you. So likelihood is that it's still ok but it wouldn't hurt to check it.
You can do it yourself with a voltmeter like so https://www.wikihow.com/Check-a-Power-Supply or take it in for someone to check for you.
Unless you've had some sort of power surge/outage and it suddenly died, it should be quite safe to plug in the other gpu briefly, just to see if you're getting any image at all. You don't even have to boot into windows, you can go into bios. You only want to confirm if it's the gpu or not and if this happened suddenly, it most likely is.
One thing to note and I'm in a hurry and can't check this for you atm but check the power draw of your gpu, and then check what your psu wattage is. If your card is very new compared to your system/psu and very power hungry compared to what your psu can supply, then don't plug it in.

I changed the graphics card still no image.

Ah ok then it doesn't mean it isn't your gpu, cause your older system might not have bios update to recognize the newer card and might be giving you a false negative. At this point, unless you have another newer computer into which you can plug in your gpu to check its health, and swap out psus to check those as well, your best bet is probably to take it into a repair shop where they can do this for you as they have plenty of parts lying around. They'll check both, and whatever is dead, give you an option to swap.
With older systems, replacements can get pricey to the point that it's almost as expensive as to upgrade so figure out what is functional, and if it's worth replacing or just upgrading around the newer gpu.

I checked PSU all 12v pins are 16 and every 5v pin is around 8-9
3v pins are 5-6v is this way to high? I used the paperclip method for testing

 

[Sedivy]

Here's the table of tolerances. Should be within 5% of the advertised values:
https://www.lifewire.com/power-supply-voltage-tolerances-2624583
5-6V on 3V rail is unlikely. You might be looking at 5V rail. But if it's reaching 6, that's way over tolerance levels yes.

I will check again thanks for the link

That 4.42 is not good. Assuming that's from a 5V rail. That 16 is insane, that might be cause of no load on it. I wouldn't put much stock into that value. Check 3V one, then once you reconnect everything and turn the computer on check the 12V reported in hwmonitor. I'm not a fan of these for voltage measurement but it's the safest thing to do for measuring under load if what you're getting with a multimeter is way off base. There's a way to do it with a voltmeter (http://www.tomshardware.com/forum/335578-28-test-connector-voltage-multimeter) but I wouldn't, I'm wary of electrical mishaps and I'd rather you don't get hurt. I'm not sure it's necessary anyway, that 5V result is not good and I'm curious to see what you get with a 3V one.

4.42 is from a 3.3v pin

O:
Yeah....that's really not good. I'd definitely swap in another psu, from a different computer, to check if any other components got damaged (gpu for example) by this, but your psu likely needs replacing.
Typically you'd expect lower voltages than needed though. I'm a little surprised to see it that high. Regardless, swap in another, just to check the rest of the system.
Did you have any power outages? Any power work in the area? No issues with any other electronics in your place?

It's ms-tech no 80 plus rating psu
750w

 

[Sedivy]

Yeeee....that...I don't know that one, I can't find any reviews, which should tell you probably isn't that great. Their 550W edition is listed as a lemon (http://www.johnnylucky.org/power-supplies/psu-lemon-list.html) so my guess is this is crappy psu blowing up prematurely and maybe taking your gpu down with it.

Here's a nice tier list:
http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html
so pick something from tier one or two. (two is probably better value for you)
Also http://www.jonnyguru.com/ is a great site for psu reviews, and tomshardware has been doing their own as well so make sure you pick something that doesn't have to be top of the top, but just something confirmed as decent quality that won't crap out on you like that.

I think it might killed my mobo because I use a pcie only gpu and that won't work

 

[Sedivy]

Your pcie gpu should be fine with your mobo, but it is an old system now that I look at the specs. It might time to consider an upgrade.
This is up to you. You can probably find a decent tier 2 psu to put in but if any other components are fried, then replacing gpu might not be worth it for you, and you might want to save that money towards a new rig. That being said, you can probably find a replacement for the gpu as well, just...not very cost efficient one probably.
The thing is if you went with a new system, the gpus are currently so insane in prices due to cryptomining craze, that you'd be spending way too much money for value. Unless you did a bundle/combo purchase that some stores occasionally do, that offers cards at their real price, or build within a brand (like evga diy build https://www.evga.com/products/diy/), right now buying new gpu is a nightmare. The card I bought less than a year ago for example, now sells for like 200-300$ more than its real price.

All of this is speculative though. Your mobo and your gpu might be just fine. You need to put in another psu, from another computer and check what's alive and what's dead, before you decide on upgrading or not.
