[SOLVED] Computer won’t display

[Sekcmexi]

Just built a new pc . After one month or so I started having trouble turning it on. I would turn it on and all I would get is the monitor to stay idle and would leave the power button on the monitor In breathing mode but all components like fan , gpu rgb,rgb would all work.(monitor is also brand new and worked on another computer) After A ton of attempts it finally turns on and after a ton of repairs and blue screens of death it finally worked randomly. I Uninstalled some anti virus cause it said it could do that and then Played for a few hour and turned off to come back the next day and the same thing. . I took out all the cables and plugged them all back in swapped ram cause I thought it was that and Nothing. Swapped gpus still nothing . Both gpu and ram that I did swap were both brand new (friend let me swap to check)I took out all the pwm fans and rgb cables and tried that and nothing. Now all I have is the components working but nothing showing on the display. So it’s either the psu, mobo or cpu. Anyone ever have this issue if so what did you do what should I do? Here are my specs and thank you for whoever responds.

Question. I’ve actually changed the cpu cooler a couple of times because I didn’t like the way they looked until I saw the corsair 115i . I’m not sure how knowledgeable you are with different parts but I wouldn’t think it’s that. I’ve read so much about different hardware. I also changed the ram for an rgb ram same goes for the gpu rgb that’s why I said it couldn’t of been those because with my original I reput all the old parts and the computer didn’t work so there was no way both gpus broke and both rams broke . Get me? So I think you might be right with the cpu or even the mobo. I don’t think it was even the psu to be honest. Either way we’ll find out once I get my new mobo and cpu . I’ll keep you posted. I should have all my parts in 2 weeks depending on how this virus is. Hope all is well with you and the fam and friends ! Thank you for everything!

corsair 115i is one of the best coolers to use for the cpu😍....really and using different parts cant really cause any problems i mean its components that function on their own.
I have ran a full compatibility check with all your pc components you listed in your threat earlier...everything is 100% compatible and supportive.So just like you have said nothing can be broken but the cpu or your mobo has some issue we are struggling to find...I know and i have a feeling that you wil reach success with the new mobo and cpu you are going to get!

So you are going to keep your other pc parts and just get a new cpu and motherboard?
if indeed you are keeping it Great!Its a real powerful computer you have...
But till then my friend...Stay safe and i hope all is well with your family and friends as well!
Lord be with you

yup just a new cpu , psu (since I already returned the old one) and mobo. I already have 4, 140mm rgb fans and 2, 120mm rgb fans from corsair. And the cpu cooler. Just won’t on my new 510 elite case from nzxt and the rest of the parts . Thank you! And take care

Hey i know that youve rma'd it, but did you try reinstalling windows? Pretty basic thing to do but sometimes its a bad install.
Im not an expert.

Hi Lacedup...This situation is nothing to do with windows at all...this threat is about the computer that doesn't boot into bios.
Bios needs to boot first TO be able to boot into windows....Sekcmexi cant perform a reset of windows as he is not able to boot into windows.

yeah my fault didnt read it all

No worries bro

So I got a new mobo a new cpu and new psu..same freaking problem. I ordered a new gpu and ram and waiting on that. I got to boot to bio and fixed some things and then just deleted windows and reinstalled it. Installed some things updated bios . Started installing some games and then when I restart 2 or 3 times the screen goes blank and after a few times it repairs and I lose all that I downloaded. The only 2 things I can think of is my gpu or ram... I thought it was the extension wires I got to match my case but it wasn’t. If this new gpu and ram don’t work imma lose it .

Hi there Sekcmexi
Thank you for coming back to me with your update on this threat.
Well first of all i'm glad that you managed to get into bios in the first place...and that you have reinstalled windows and just at the point where you could use your computer again normally like any computer...but then the situation happened AGAIN.
So now we know that ITS NOT the PSU and the Motherboard and the CPU defnetly!!So my thought is...RAM.
Well if you said you already ordered a new GPU and new RAM....we could wait for those components to arrive to see whats behind this all(Because its basically a complete new system) OR we can troubleshoot further on.
So What i believe at this veriest moment is that it could maybe be ram then...You have 2x8GB DDR4 ram chips connected to the mobo....Use only one RAM CHIP at a time PER RAM SLOT with EACH RAM CHIP.
IF still nothing Disconnect your GPU and insert your ram chips again but connect your screen to the motherboard itself....If you boot into your Bios then....Well then we all know that its your Graphics card and not the ram or any component there connected.You can also try to do that BUZZ Beeping trick i have told you...(where you disconnect all your ram and your gpu then you start up the system and listen if there are any beeping).

Well the reason why I think it’s the gpu is when I take out the gpu it works fine and I can get into bios and into windows find. Once the gpu is connected I get that blank screen. I haven’t slept cause of this so imma nap and take out the gpu and see if I can restart it 5 times without getting ring a blank screen but like I said when I was getting into bios and updating windows I was not using the gpu

OOh i see then well yeah we have the reason behind this...Then its defntely your GPU my friend...i mean if it boots windows and bios perfectly without the GPU connected then its defnetly that.
Well sorry we could figure that out earlier bro and keep in mind that it could maybe the PCI SLOT itself sometimes but i believe that's not the case and that its litterly the GPU itself.
Lets see when your new graphics comes then we can test that theory again.

 

[Sekcmexi]

I appreciate all the help brother! Thank you and I’ll keep you posted tomorrow when it comes In

 

[Bassplate]

No problem bro thank you
I Hope it works and Good luck!
Stay safe.

So I'm currently ON my PC without a graphics card installing and updating stuff and done several restarts with 0 Problems.... all RGB is connecting fine. All fans working CPU cooler is fine mobo seems fine to. Its crazy... im actaully thinking it was the OLD MOBO and GPU to be honest.. because my other set up had been working with it fine until i started adding <Mod Edit> to the comp.

 

[Sekcmexi]

CPU is running a little hot might have to restock the CPU cooler but other then that.. things are running fine.

 

[Bassplate]

Well bro i'm really glad that you managed to figure it out at the end!
Now you just have to wait for the new graphics and then your PC will be up and running and ready for gaming or what ever you plan on.
Ill suggest to use the Arctic silver 5 Thermal past for your CPU...i think you would have no problem with the heat of the CPU if you use that Thermal past.Well just check your CPU voltage at your Bios if it runs at recommended volts and if its not being overclocked...also keep in mind that your CPU will be hot because of that the CPU must run both Processing and GRAPHICS because of no graphics card installed....So basically the CPU is doing the GPU work.

 

[Sekcmexi]

i actually didnt like that thermal paste. i did better with the noc thermal at least from what ive used. and its at a ssteady 40 playing WOW lol

 

[Sekcmexi]

as long as im n ot hitting 50 on my CPU and 60 on my gpu on overload then ill restock the cooler but ty man.. i will keep you psted

Ether way bro any thermal past will help...as long as there are thermal past on.
Thanks man and keep me updated

 

[Sekcmexi]

ok! so i just got the 2080 and so far i have zero problems computer is running amazing. Ran some benchmarks and cpu in overload goes up to 40c and 76gpu lets see how this work after a couple of days.

That's good bro I'm really glad for you!Just keep faith and trust your PC that it will no longer give any problems again.Make sure everything is updated and that your components drivers is updated!!I'm glad we managed to find the problem together...it was really fun working with you and to share my idea's to you!!Now you have some more knowledge and more understanding of your hole system!
Thanks for trusting me in the first place man!😉
And sorry i couldn't have figured the problem out earlier.
Stay safe as always and happy gaming!!

 

[Sekcmexi]

No thank you for the quick response and helping me! I appreciate everything!! I’m sure we’ll talk again. Thank you so much bro and god bless!! We well and stay safe !
