What is the BEST computer/hardware testing software -- free or paid???

Hello. I have a question.

What is the 'best' (Yes, your opinon... ...but please provide some concete facts based on your opinion.) computer testing software/hardware on the market -- free or paid (like trialware) software??? I say 'computer/hardware' meaning, ALL functional hardware components (motherboard, CPU, graphics card, memory, PCI cards, hard drives, optical drives (if this one is possible), Chipset, cache, etc.). For each of those components, I am looking to evalute at voltages, power, temperatures, data transfer speeds, RPM fan speeds, etc.). If it can run diagnostic tests, please indicate if yours or the one you know of can. I am looking for general (all components); all around, detailed/comprehensive information provided out there. Free or paid program is fine. If 'paid' as long as it is under $50-60 max. for it. Yes, this is for a 'home' user application.

Please reply.

Thank you!

Free and you dont have to install it

 

OCCT pushes all of one's machine to the fullest, meaning %100 load and logs graphs, I use this for 24/hrs straight when building a new machine to ensure that it can handle any load. Then there's memtest86+ for RAM, and you can always get a HDD maker's utility to test the same, all for free. I haven't heard of anything else but there are other good S/W's out there.

 

Hello. Thank you for your replies!!!

Any ideas or opinions about Sandra Lite or not? How does this stack up with the ones you use or aware of... ...or any other ones out there as well?

If anyone can think of more, please reply.

Thanks!

 

Hello, I like HeavyLoad by JAM software. It is not crippled like the others.
Also, another good one is Furmark for video testing.
