Problem with black screen during startup after changing CMOS battery.
Problem with black screen during startup after changing CMOS battery.
I just changed the CMOS battery on my motherboard due to persistent long load times for the splash screen, and since then I’ve been seeing a black screen. There’s a display, but it’s completely blank. The “No signal” warning isn’t showing, the splash appears normal, but after that it turns off instantly. Also, pressing the power button causes the PC to shut down right away. Any assistance would be really helpful.
The PSU's make, model (or part number), age, and whether it was purchased new or refurbished are unclear. Additionally, here are some suggestions:
- Remove your GTX 950 completely
- Connect the monitor to MoBo
- Check if you can boot into the OS
My PSU is an AURA GP450W power supply. I bought a new one this May.
1) I attempted to use my onboard graphics card by removing the 950, but it didn’t work.
2) I’m not sure what this means—I’m not very experienced in this area 😅
3) I plan to try booting into BIOS later today with the 950 plugged in, but even when I entered BIOS with the onboard GPU, it worked fine. After exiting BIOS, the screen goes black.
Gamidas Aura? If so, holy hell... that's a poor quality PSU. Also, it isn't a 450W model, it's actually 348W. That's the capacity of the +12V rail at 29A. So, why did you end up with this subpar product? Your GTX 950 should be fine. The problem must be elsewhere. (This testing helps to pinpoint the issue.) It was working before, but now it isn't. If you can reach the BIOS, CPU, motherboard and RAM are generally functioning properly. You should be able to boot into the operating system if the SSD and/or OS installation are intact. If not, consider a clean OS installation or a new drive. But a new PSU is essential. This time, don't compromise on quality. Seek a reliable, high-end PSU such as Seasonic Focus/PRIME or Corsair RMx/RMi/HXi/AXi. Super Flower Leadex is also a good option, though they're harder to find.
All three of my PCs are powered by Seasonic, with full specifications and photos attached in my profile.
Remember: Since the PSU powers everything inside the PC, it's the most critical component. Never cut corners on the PSU. Also, avoid purchasing used units.
Summary:
1. Get a new, high-quality PSU.
2. Check if you can boot into the OS with a fresh, reliable PSU.
3. If booting isn't possible, format the OS drive and attempt a clean installation.
4. If the clean install fails, it likely points to a faulty SSD. Then consider a new SSD or HDD drive.
5. Once a new drive is ready, perform a clean OS installation there—this should resolve the issue.
Also, low-quality PSUs can cause significant damage or failure to your entire system. If you discover your SSD is damaged, you might be responsible for the issues caused by the faulty power supply.
They were very right! This PSU definitely failed after I swapped in a CMOS battery. 🤔
I connected an older PSU that I had on hand, and the screen lit up instantly. It’s really impressive how quickly you can identify the problem with a PSU. Thanks a lot for your assistance.
I wasn’t sure what kind of bad it was, because it’s tough to find decent computer parts locally, haha
There is a reason why I've added the "Ambassador" tag here in TH forums. You're welcome. In most cases, it's not about availability, but rather: #1 Not enough knowledge about PSUs or #2 A cost-focused attitude Often both at the same time. For reference, you can check the PSU Tier List, link: https://forums. In general, anything from Tier A should work. However, the list hasn't been updated recently and won't be for a while. Still, this tier list can serve as a helpful guide for those unfamiliar with PSUs. Additionally, if you have questions about a specific PSU—such as one not listed in the tier list, like certain Gamidas models—you can always ask directly here. We have many knowledgeable members who can advise on whether a PSU is suitable. I can discuss PSUs extensively, but for more information, please visit: topic: https://forums.
