So I’m having issues with my PC and it started two days ago. It’s just constant black screening and my monitor will go into save power mode.

I’m running a windows, ASUS 550-F gaming, 5950x cpu and a 3090 gigabyte graphics. 2x 32 gb ram. My ssd also had some issues so I got a new one to try to trouble shoot but even after entering bios, my screen would go black after a couple of seconds. It’s posting and the lights on the motherboard go through. Iv reseated my ram and gpu. Changed out the cmos battery. Switched to HDMI cables instead of DisplayPort. Switched to a brand new psu RM1000x. I can’t even get into safe boot mode without my pc going black screened. Graphics drivers were updated to the latest about a week or so ago.

Not sure what else I can do to try and fix this or what the issue would be.

Hey everyone, just a quick heads-up: I'm Japanese and using a translator to write this, so I apologize if my English sounds a bit weird or unnatural at times! Honestly, this issue has been driving me insane and really taking a toll on my sanity, so any help would mean the world to me right now.

My rig originally started out as a prebuilt BTO system, but around 2023 I swapped out the GPU and power supply for an RTX 4070 Ti Super and a 1000W PSU (Kuroutoshikou). Everything was fine until about this past August, when I noticed that after roughly 2 hours of gaming, the system completely freezes for 2 to 3 seconds. I mainly play FFXIV and occasionally Monster Hunter Wilds, and the exact same freeze happens in both games. Those are pretty much the only titles I play right now, so it doesn't look like an issue exclusive to one specific game engine or client.
About a week ago, I basically rebuilt the entire machine from scratch—new motherboard, CPU, RAM, case, etc.—keeping only the GPU, PSU, and SSD. Unfortunately, the exact same freeze still happens, which leads me to believe the problem has to be with one of those three carryover parts.
I’ve already checked the SSD using Windows drive health tools and command-line checks, and it reported back completely healthy. For the GPU, I did a full clean driver reinstall with DDU, but no change. My initial thought was that the GPU might be dying, but the weird part is that for the first two hours, performance is rock solid. Stress tests and benchmarks run fine, and monitoring logs for temps, voltages, and currents show completely normal numbers right up until the freeze happens. During the 2-3 second freeze, the readings just drop or flatline out of nowhere, almost like an instantaneous blackout rather than a gradual thermal or power throttle.
I’ve also gone through in-game settings, disabled Discord overlays and hardware acceleration, closed background apps, and tried every software tweak I could think of, but nothing has helped. Has anyone run into something like this before, or is there anything else I should be testing? I'm starting to suspect the PSU, but I'm really open to any suggestions at this point.

Pc is 4080s, ryzen7800x3d, t force delta 32gb cl30 4800-6000mts, rog strix x670e-a, and 1tb snx850 but with a heat sink preinstalled . Pc has been cause me troubles for months, sometimes can play, sometimes it crashes within 5-20 mins and consistently, sometimes reseating ram works but only till the next day. Throws up a whole bunch of different blue screen codes, loosing my patience here after spending all this money.

PC Crash randomly and whenever I select "Slice" on a 3D printing program to convert Cad to G Code. I have screenshots of the event viewer of the most recent crash. That's where my skillset is crippled. Any help would be appreciated.

I’m to sure what this noise is, my laptop can run for a few seconds up to a couple hours before the noise starts, it isn’t overheating, everything runs as it’s supposed to, it’s just that noise that’s the problem

I'm about to get a replacement PC tower, as my current 5 y.o. one is on its last legs, with memory issues and other problems. I have several programs on there that are registered or have serial numbers. Is it possible to "transfer" them to the new PC? How can I find out the serials or registration numbers/keys? I'm hoping to save as much of the other stuff on the old one as possible, while it's still somewhat running. The old PC has windows 11, the one coming has Win 10 but I'll upgrade it to 11.

Just posted this in another subreddit but wanted to post here to for visibility and possible assistance as well. Thank you

PC Crash randomly and whenever I select "Slice" on a 3D printing program to convert Cad to G Code. I have screenshots of the event viewer of the most recent crash. That's where my skillset is crippled. Im assuming its a resource issue, but when I look at my GPU and CPU Temps and usage, they are at normal levels. Any help would be appreciated.

Hello guys today i upgraded from an rx 6750xt to a 5070 and wanted to tested my gpu on fortnite but i couldn’t because my ping was horrible. Before swapping the gpu’s i had no problems at all and i am certain i don’t have problems with my internet, so what can i do?

Hello everyone, you are my only hope for solving this problem. I’ve been having issues with my laptop (Dell G15, Ryzen 5 6600H, RTX 3050, 16GB RAM); it displays these errors every time I turn it on. I took it to a repair shop, and they said they couldn't find any hardware issues. Sometimes the laptop boots up and works perfectly, but other times it doesn't. Does anyone have the expertise to help me?

sorry for the translation im from argentina
