Hardware Problems

Is there a test you can perform on the computer?
To let you know if monitor, motherboard, or anything else is not working correctly?

Thanks in advance

 

Well no offense, but if the monitor is turned on and you can see your computer desktop and stuff, then im pretty sure its working :X

and for memory you can go do memtest...

google it, im not exact on the website i think it has a number like 86 on it.

 

what is it doing.
and maby what kind of pc is it.

 

If "not" working correctly? It is often hard to notice performance going downhill slowly over time - until suddenly you realize something that use to take seconds now takes minutes. But generally, if performance is not smooth, you got problems. Are you having problems, or just want to know?

There are 100s of "benchmark" and you really need to use several to get a good picture of your (how you use your computer) real world performance. But even still, if you look at comparisons of CPUs, for example, when the benchmark shows the worst performer takes 17.1 seconds, and best takes 16.3, does it really matter to most users? And you have to be careful of any bias in the benchmarks - intentional or not. By that I mean if a review site caters to the gaming community reviews a graphics card, the card that bests all the benchmarks may make a lousy card for computer aided design (CAD). And certainly if a marketing department is behind the benchmark - you end up with Ford, Chevy, Dodge, and Toyota all citing tests that prove, beyond doubt, their truck is the best truck.

For monitors, yeah, the human eye is pretty good at detecting bad graphics - though the human brain is pretty good at ignoring and compensating for them too. That said, if you think you are having monitor problems, the easiest way to test is to swap monitors and see if the problem follows your monitor to the other computer, or remains on your PC.

Plug-in PSU testers are available but are a poor substitute for a qualified technician using an o'scope or power analyzer. So swapping in a good PSU is often a good option.
