I'm having some serious issues with my ABS Master Gaming PC. It's got some decent specs: Intel i5 11400F, GeForce RTX 3060, 16GB RGB DDR4 3200MHz RAM, and a 512GB M.2 NVMe SSD paired with a WD_BLACK SN770 2TB SSD. Yesterday, while gaming, my game just quit, and I noticed that the games on my external hard drive were missing. After that, I tried resetting my PC, but it kept happening. Trying to update the games on my external hard drive resulted in driver errors and corrupt files. Updates for Windows 11 also would get stuck on the restarting screen. I've done a few troubleshooting steps like Check Disk and sfc scannow, which found corrupted files but didn't seem to fix anything. Bootrec attempts and updating drivers didn't help either. Now, when I turn on my PC, the GPU light blinks and nothing shows up on the display. Is there anything else I can do, or is my PC toast?

Make sure to check if the power connections to your GPU are secure. Sometimes, loose connections can cause those blinking lights and display issues. If you’re confident that everything is plugged in properly, you could also try reseating your GPU in the PCIe slot—just remove it and put it back in. If the issue persists, it might be time to consider a hardware failure.
It sounds like you might have a faulty drive which is causing all sorts of issues with your PC. A good first step would be to completely disconnect any drives you suspect might be causing problems. Try booting the PC without those drives connected and see if you get any display output. It should at least try to enter the BIOS if no boot drives are detected.

I actually pulled out what I thought was the faulty external SSD, but then the display completely stopped working and the GPU started blinking again. Any other ideas?
