Huge performance drop - - - is my PSU faulty or is there something I am missing ?
Hello everyone and thank you for your support.
I haven’t been very tech-savvy before, but a few days ago my PC suddenly dropped in performance overnight. Even simple tasks like watching YouTube caused noticeable stutters.
The next day I played CP2077, which had around 40-80 frames per second depending on the area, and played Hearthstone at maximum settings. However, upon waking up, everything was freezing and stuttering—around 10 FPS on CP2077 and about 50 on Hearthstone.
I did some research and thought it might be either my GPU or my PSU that’s failing.
Additionally, my PC’s performance is normal for the first 15 minutes after turning it on. I ran a Furmark test right after powering it up, and everything worked well—around 140 FPS, about 200W usage. But now that the PC has slowed again, I’m seeing only 30 FPS with around 15-20W usage.
So my question is: is the GPU not delivering enough power, or is the PSU not providing enough?
Apologies if I missed important details; I’ll try to reply quickly in the thread.
Note: The PSU has been in use for roughly 4 to 5 years.
which also contains the power supply, and also records the total duration the PSU has been operating.
combining RAM kits can cause various issues from both hardware and software perspectives.
even if it appeared acceptable recently; test using just one packaged kit in the correct DIMM slot to compare performance.
Thank you for the suggestions regarding the post. I'll attempt the RAM stuff and keep you updated on the outcome.
it does make sense, but it’s worth checking if the problem lies with another part. you might want to visit your local PC store for a more accurate diagnosis.
Ensure BIOS and all component drivers are current, execute several Memtest86 cycles, verify OS and game installation media for issues, confirm that component temperatures remain within acceptable limits during stress conditions, and utilize Windows SFC/scannow to inspect system files. Begin by testing the system with a single RAM module and proceed through the previously outlined steps. If you lack access to a compatible spare system, consider testing hardware in a local shop or using a backup PSU.
After installing the PSU and believing the problem was resolved, the same issue resurfaced. I'm uncertain if the GPU is malfunctioning or if the shunt resistors are faulty. I plan to reapply thermal paste to both the CPU and GPU tomorrow and proceed further.
