Which OS are you using ? Windows 10 or 11 ? Is it a freshly installed copy ? Do you also have all the necessary software installed, such as VC++, DirectX, .NET, and even an updated BIOS/firmware ?
Your post lacks enough info to start any troubleshooting process. You need to provide more details. Exact brand and Model number of your GPU ? Make and Model number of your current PSU ? On what resolution are you gaming ? What's the make/model of your CPU ?
What's the CPU and GPU TEMP value under full load and idle desktop mode ? Any signs of overheating ?
Anyways, kindly provide full PC specs.
-1. "Complete" system specs should ALWAYS be accompanied with any driver, hardware, or performance question. Do not post DXDiag reports as they contain a TON of useless information. Posting a DxDiag in place of a System Spec List tends to ward off potential members from helping you.
Please supply the following system details/information. As much as possible for you. NO need to provide each and every detail though. This is just for reference.
(Complete System Specs)
-CPU make and model# (clock speed/voltage, type of cooler, and "Core" temperature @ idle and load)
-Motherboard make & model# (include Bios version if graphics card is not recognized or you are having stability issues)
-RAM (amount, clock speed, model#/link of kit, configuration)
-Graphics card(s) make and model# (clock speed, voltage if modified, Driver version and GPU temp both @ idle and load)
-Power supply make,model#, "AND" age (note if using 110V or 220V A/C input)
-HDD/SSD configuration (ie: Raid setup/ back up/ OS drive/etc..)
-Case/Chasis make,model# (fan make, model#, and configuration if having thermal issues)
-Operating System (If using Windows note Framework and service pack version)
-Monitor make, model#, and resolution (If model# is unknown list resolution and refresh rate)
*If the unit is a "laptop" or "All-in-one" system you must note the make and model# of the unit. Be sure you are ALWAYS using the OEM/manufacturer's Driver updates for the unit.
*If "Crashing":
-Note the nature of the "crash" in detail, as there are several definitions for the word "crash".
*If "performance" related issue:
-Note the "exact" point in which the performance reduction occurred (ie: After Windows update, After Bios update, After Driver update, After thermal system shutdown, After Hardware change/upgrade etc...)
*For diagnostic purposes please disable the following:
-Any/all Antivirus/ Anti-malware software
-Any/all OSD monitoring software
-ALL overclocks outside of factory spec .
