Diagnostic cards?

[artois7]

I'm sure this has probably been discussed before, sorry if I've missed it.

Now I'm sure we all spend a lot of time fiddling and swapping hardware to pin point the faulty component, and we've probably all seen these £30 diagnostic sets on ebay which say they'll find the fault by simply plugging them in.

Although I doubt they'd be much help, I think they could possibly be useful for pinpointing a faulty CPU against a faulty motherboard.

Has anybody used one, if so what have you got and what are your thoughts? Budget isn't really an issue since if it works, it'll pay for itself.

In my opinion there is no such card that will tell you the exact problem . it might point you to the right direction but if a motherboard is dead it can't help at all.

My diagnostic card sometimes stays at BIOS CODE "no" but laptop works. So there isn't much use of it, but sometimes comes in handy.

Which situations does it come in handy?

Re: Diagnostic cards?

well, only as a last resort, and i don't know what else to do
I plugged it in at the beginning, i check the CPU and RAM, but it says BIOS code "no" most of the time, and the QiGuan codes also doesn't help (reset signal detected twice or more...), and that leaves me at square 1, again.
