Question PC Disaster Please Help
Hello everyone,
I'm trying to keep things brief.
About a month ago, my ASUS ROG GT51CA PC would suddenly crash during a game—after just over six minutes. I tested the CPU, GPUs, and PSU; everything seemed okay except for the PSU. I ran stress tests on the power supply and even checked the 24-pin cable without any fan. That’s when I upgraded to a better PSU with more watts and quality.
After installing the new PSU carefully, I noticed my monitor wouldn’t show any signal at all once it powered on. All fans were running, LEDs were lit, but the screen was blank. I double-checked connections, cleaned the RAM, etc. Back then, with plenty of online help, I always managed to fix PC issues. Still, I ended up taking my PC to a reputable repair shop.
Their diagnosis wasn’t encouraging—they said my graphics cards and motherboard were damaged by liquid. What?! I’ve never spilled anything near my PC, let alone on it?
Anyway, I swapped the motherboard with the same model and got a new graphics card. I reassembled everything, but it still wouldn’t power on or show any signal. I rechecked all connections, replaced the RAM, and even tried reinstalling the CPU, but nothing worked. The LEDs stopped lighting up too.
What should I have done? The new PSU is fine. Previously, with a bad PSU, my PC would still boot up but crash after six minutes of gaming. Why did switching to a high-quality PSU result in total failure? Everything inside the computer was working perfectly before, yet now even the new or old CPU wouldn’t power on.
That definitely wasn’t a quick fix. Sorry for the confusion.
Thanks for any advice!

what the full system spec now?
include brand and model of the psu
It might be a short circuit, but the shop should check it out. They gave you a new motherboard and GPU instead? Then you bought a replacement CPU yourself? Are there other PC shops nearby? Display issues can occur even on healthy PCs, so proper diagnostics are needed rather than just recommending replacements. For instance, I've experienced losing my display four times on my own PC, with both an iGPU and a GPU working. Sometimes I had to restart the PC using a CMOS reset. Despite this, all components were fine; it was likely a BIOS setting change that affected it. In any case, you're facing multiple problems at once, making it hard to explain them clearly. I notice you have a new power supply with only enough power. A single 2080 Ti can consume up to 300w, possibly closer to the 250w it claims, but it can go higher. You have two units, which adds about 600w just for the GPUs. Including the 91w or more drawn by your CPU and other parts, you're very near the PSU's capacity. I suggest starting with a CMOS clear; if that fails, have a shop verify it and ensure everything works properly.
