Unusual shutdown events, blue screen occurrences, and hard disk disconnections.
Unusual shutdown events, blue screen occurrences, and hard disk disconnections.
My computer powers off when loading AAA games. FPS decrease is noticeable during competitive matches like League of Legends and Valorant. This issue began about a month ago. Initially, the hard drive vanished after startup and emitted a clicking noise. I suspected a disk problem first, then ran HDD Sentinel and everything appeared normal. During idle, my CPU cooler LED dimmed intermittently, suggesting power struggles. When the PC restarts, it lights up again. This behavior was unusual since it's just a standard LED with two power connections. Recently, while playing Risk of Rain 2—a lighter title—I experienced similar problems: HDD would disconnect and reconnect every 15-20 minutes. In Forza Horizon 5, the game froze unexpectedly, even though it ran smoothly at high settings. Using NFS Heat caused a complete shutdown during load. I performed CPU stress tests with AIDA64 showing no throttling and temperatures staying low (67-70°C). GPU tests via MSI Kombustor also showed stable performance up to 70°C. Suddenly, a blue screen appeared. After repeated attempts, the PC crashed again after a few minutes of clicking noise. I ran diagnostics with AIDA64 and Kombustor, but this time it crashed with a blue screen. Following the test, a hard disk click occurred. Could you help identify the likely faulty component? I’m considering the power supply unit, though other advice would be useful. My specs are: Intel 6700K, Gigabyte B250 board, 32GB RAM at 3200MHz, Zotac Nvidia 1660 GPU, Zotac 970e Plus SSD, Seagate 2TB HDD, Toshiba 1TB HDD, 7200RPM PSU from Thermaltake 630W.
Perform a crystal disk analysis on your storage devices and provide the results. Ask about the age of your power supply unit.
Crystaldisk confirms every disk is in excellent condition, with a performance rating of 98%.
Additionally, I ran a test using the crypt disk and they performed exactly as intended.
I think it might be a PSU issue. That particular thermaltake PSU is at the bottom of the tier list and has been around for about 6-7 years. Has it ever experienced any problems during that time? Edit; I rechecked your original message, and now I’m less sure about the previous assumption. With a blue screen, a typical PSU failure usually causes it to shut down immediately, not just a black screen.
The GPU seems to be triggering crashes during testing, especially when paired with the CPU. It might be related to the power issues—possibly due to age—or the LED dimming could be another sign. The HDD disconnection adds more confusion to this unusual situation.
Bizarre indeed. Now with no load just browsing there is no problem. I can even run stable diffusion model with ease. No bluescreen there. I face the problem while playing only games. I am thinking there could be some problem with motherboard. My original one had some problem so brought one from second hand market. It is a refurnished one. But if motherboard had problem gpu and hdd which are powered directly shouldn't face any problem.
It might be time to give everything a refresh. The processor, motherboard, and power supply need updating. My processor is nearly ten years old.
The stats at the top in CDI is basically useless. The health status is useless because it's up to the manufacturer how much it has to fail before before the status changes from Good to Warning/Bad. You rarely see drives get warnings these days. The percentage is not related to the health at all. It's how much of the warrantied writes you have used. You have to know how to read all the parameters below the general information and know which ones are important. With modern SSDs they have removed almost all of the useful attributes and just lumped them into a single stat. The problem is that this stat also monitors lots of other things that aren't about the health so you have no idea if it's counting bad stuff or not. On modern SSDs, the self diagnostic is practically useless. If need help reading the CDI parameters, click Edit → Copy at the top (It includes all drives, not just the selected one), paste it to a pastebin and link to it here. Also post the dump files in case it's BSODing for the same reason it's having shutdowns. Go to C:\Windows\Minidump and check if you have any minidump files. If you do, go back to the Windows folder and copy the Minidump folder itself to the Downloads folder (You can use the desktop if you don't have OneDrive syncing files). Zip the copied folder and attach it to a post. Please follow the instructions to the letter as Windows doesn't like you messing with files in this location.
