Question Black screen on startup after replacing CMOS Battery.

[AveragePlingus]

So I’ve just replaced my CMOS battery on my motherboard because I was having long splash screen load times, and ever since I did that I’ve been getting a black screen on my monitor. There is a display, but it’s just a black screen. The “No signal” message isn’t there, the splash screen appears just fine, but after that it just goes dark. Also as soon as O press the power button, the PC turns off *instantly*. Any help is greatly appreciated.

Specs:
Intel i7-3770 3.4GHz CPU
Gigabyte GA-H61M-S2PV Motherboard
Nvidia GTX 950 GPU
8GB DDR3 RAM
Boot drive is a 120GB SSD that was functioning prior to this incident.

PSU make and model (or part number) is? Also, how old the PSU is, and was the PSU bought new or used/refurbished?

Also, something to try;
* Take out your GTX 950, completely
* Connect monitor to MoBo
* Look if you can boot to OS

My PSU is a AURA GP450W power supply. Bought new this May.

1)I tried using my onboard graphics card by removing the 950, to no avail.
2) Not sure what this means, not that experienced in this field 😅
3)I’ll try booting into BIOS later today with my 950 plugged in, but even when I booted into bios with the onboard gpu, bios worked fine but after exiting bios the screen goes black.

Gamidas Aura? If so, holy hell... that's crap quality PSU.

Also, it is not 450W unit, instead 348W unit. Since that's what +12V rail at 29A is able to deliver.
So, why on earth did you buy this crap?

2) Not sure what this means, not that experienced in this field 😅

Your GTX 950, most likely, is fine. Whereby issue lies somewhere else. (This testing helps to narrow down things.)

Boot drive is a 120GB SSD that was functioning prior to this incident.

Was functioning? But isn't anymore?

but even when I booted into bios with the onboard gpu, bios worked fine but after exiting bios the screen goes black.

If you can access BIOS; CPU, MoBo and RAM, for the most part, work fine. So you should be able to boot to OS, IF SSD and/or OS installation is sound. If not, may need look towards clean OS install and/or new OS drive.

But new PSU is a must regardless.
And this time around, do not cheap out on PSU. Instead, look for proper, good quality PSU. Like Seasonic Focus/PRIME or Corsair RMx/RMi/HXi/AXi. Super Flower Leadex is also great, albeit those are harder to find.
(All 3 of my PCs are also powered by Seasonic, full specs with pics in my sig.)

Keep in mind: Since PSU powers everything, it is the most important component inside the PC. Thus, never cheap out on PSU. Also, never buy used PSU too.

Recap:
1. New, good quality PSU.
2. Look if you can boot to OS with new, good quality PSU.
3. If not, format OS drive and try to make clean OS installation.
4. If clean OS installation fails, it indicates failed SSD. If so, look towards new OS drive (SSD or HDD).
5. When new OS drive is needed and it has arrived, clean OS install into that one. This should fix your PC.

Btw, crap quality PSUs have magical ability to degrade or outright fry everything they are connected to. Aka your whole PC. So, if you do find out that your SSD is toast, you can blame your doorstop named Aura GP450.

I’ll check them out and let you know. Thanks!

You are so correct! This PSU apparently fried itself after I replaced a CMOS battery. 🧐

Plugged in an old PSU I had laying around, boom. Instant windows logo. That’s honestly quite cool how you can pinpoint the issue to a PSU almost instantly. Thank you so much for the help.

I didn’t know *how* bad this PSU was, since it’s quite hard to find affordable quality computer products where I live, haha

There is a reason why i have "Ambassador" tag here in TH forums.

You're welcome.

Most of the times, it's not about availability, but instead:
#1 Lack of knowledge about PSUs
or
#2 Penny-pincher mindset

Often both at once.

For future reference, you can look at PSU Tier List,

Essentially, everything from Tier A will do. Though, the list hasn't been updated for a while and won't be either. But for those people who doesn't know anything about PSUs, this tier list is a nice guideline.
Also, when you have doubts about PSU (e.g the one that isn't covered in PSU Tier list, like everything from Gamidas), you can always pop a topic here and ask directly. We have plenty of knowledgeable people besides me, who can tell you if PSU is good or not.

I can go on and on about PSUs , but you have your solution and if you want to learn more about PSUs, you can start here,
