Hey everyone! I've been having a few computer issues lately that I could really use some help with. I built my PC about a year ago, piece by piece, and it was working great until I swapped my old graphics card (R5 230) for a GTX 1660 Super. After that, my monitor started flickering intermittently. I discovered that the flickering was due to using the same power strip for the monitor and PC, but even after fixing this, I still have problems with my old monitor flickering after some time. I tried different cables and connections, but no luck.
Now onto my other issue: my case fans' LEDs have stopped lighting up properly, even though the fans themselves are still spinning. At first, the LEDs would turn on sporadically, but now they only light up maybe once in every 20 boots. I've rechecked all the wiring with no luck. This is really bothering me, especially since I'm also uncertain if these issues could be related to my PSU or maybe something else with the electrical system at home. To give you a clearer picture, whenever I turn on the electric stove, my main monitor goes black for a few seconds!
Here are my specs:
* **CPU:** Intel Xeon E5-2640 v3
* **Motherboard:** Machinist X99 PR9
* **RAM:** 2× DDR4 16GB 3200MHz Gloway (32GB total)
* **GPU:** NVIDIA GeForce GTX 1660 Super
* **PSU:** Mancer Thunder 500W 80 Plus Bronze
* **Case:** [this one](https://www.pichau.com.br/gabinete-gamer-tgt-skylancer-v2-mid-tower-lateral-de-vidro-com-4-fans-branco-tgt-sklv2-wh-4f)

By the way, it's a good idea to clarify that when you said 'ignite' the stove, it might confuse some people since electric stoves don’t ignite like gas stoves. They use heating elements, right?
Also, about swapping your GPU, did you make sure to uninstall the old drivers first using DisplayDriverUninstaller (DDU)? If not, that could be causing some issues too—definitely worth a try!
It sounds like your electrical circuit might be overloaded. When you mentioned that the monitor goes black while igniting the electric stove, that's definitely a sign something's off. Are those two appliances on the same circuit? If you flip the circuit breaker, do they both turn off?
Regarding the fans, your motherboard doesn't seem to support RGB directly—only PWM. Did your fans come with the case? If they have a specific connector to daisy-chain them, and you're connecting to the PSU, that should work fine. You might wanna double-check the connections or try a different power source.
I've just checked and they're not on the same circuit. I believe the fans are connected in series. They connect to each other and then to the PSU, and I also tried using the reset button as a controller, which worked earlier.
Yeah, I see that now. Sorry about the wording! And no, I didn't uninstall the drivers. I’ll give that a shot!
