I have to been offered a reasonable used desktop, whose speccs would suit me well. How can I test it before buying? Is there a diagnostic software I can burn to a CD or install on a USB stick, that anyone can recommend? As I have software to check an HDD, I assume there is a complete package? Thanks
Stress-test it. Since you already have the software for HDD testing, Prime95 for CPU. MemTest86+ for RAM. Furmark for the GPU. DPT (Dead Pixel Tester) for the monitor. and a good 2-hour movie for the DVD-ROM.
