I was wondering why vertical mounting electrolytics have like an
indented cross on them.

To release the pressure and gunk under fault conditions (or bad
manufacture).

The reason I ask is because there's 4 largeish
one around my CPU on the motherboard and they have all split open,
along the indentations.

Oh dear.

A: How old is it ? (from date of manufacture)

B: Can you read what brands they are ?

C: Has your PC sharted behaving strangely yet ?

D: What brand mobo is it ?

E: Replace ASAP with well-known brand, low ESR (switching) types.

That is REPLACE ALL OF THEM, NOT JUST ONES THAT HAVE BLOWN TODAY

Nice quip from the above

" From so many users, ranging from large corporate networks all the way
to the home user, the number one reason people give for wanting to
repair their hardware is they want to avoid a new system and the
disaster known as Windows Vista!

On a humorous note regarding Vista, I spoke to an IT guy who manages a
small business network for an insurance company (maintains a 100
terminal network), and had a bunch of failing Dell SX280's, which I
repaired. One branch had the brilliant idea to "upgrade" to Vista
systems, and his job was to make them all play nice with each other.
This gentleman was probably the most professional, polite, and courteous
clients I've ever spoken with on the phone, until we got onto the
subject of Vista....then the four-letter words started flowing
freely... In the end, he wiped all the Vista machines, and upgraded
them back to XP Pro."

Maybe he is ioncompetant. I have zero problems with Vista.

Aside from the fact it runs slower than XP on the same hardware

You're not supposed to put newer software on old equipment. Memory is cheap, just add some.


That might have some validity if there was anything useful added.

But needing twice the memory to run the same thing as before isn't any
'better' than needing twice the processor for the same performance.


It's not the same thing at all.

So much for Microsoft's marketing strategy of selling upgrade
versions, eh?


I didn't write that clearly. It's fine to put a new OS on old equipment, just upgrade it a little. Memory is cheap and is the main factor preventing a newer OS from functioning well.

Under your theory, what is the point of buying faster hardware to run
slower software so you end up where you started?


You don't end up where you started, you get more features


You mean 'features' like having to tell it twice over that, yes, you
really do want to run the program you already asked it to run?


I switched that off. Yes it was a silly idea, presumably intended to cover up some security problems.

Or the
'productivity feature' of being able to make a video your background
instead of suffering with it in a window?


Never tried it.

And of course, the biggie: transparent window borders. That one is so
useful I now print documents on special paper with cellophane around
the edges.


That is very useful. I don't have to peak under things to see stuff underneath.

and less bugs.


LOL

How can you tell with half your software gone because it's
'incompatible'?


I lost zero software. Including some dodgy stuff I though M$ would prevent operating like CloneDVD.
