Hello! Yes, there are several software options available for testing CPU, RAM, GPU, and PSU components. Here are a few options:
For CPU testing, you can use Prime95 or AIDA64. Both of these programs stress-test the CPU by running complex algorithms and can help identify any stability issues or errors.
For RAM testing, you can use MemTest86 or Windows Memory Diagnostic. These programs test the RAM by writing and reading data to and from it, checking for any errors or issues.
For GPU testing, you can use FurMark or 3DMark. These programs stress-test the GPU by running demanding graphics benchmarks, which can help identify any stability issues or errors.
For PSU testing, you can use a multimeter to measure the voltage output of each rail. You can also use a power supply tester, which checks the voltage levels and can help identify any issues with the PSU.
It's important to note that stress-testing components can potentially damage them if they are not cooled properly or if the tests are run for long periods of time. Use these programs with caution and only for short periods of time to avoid any damage to your hardware.
