[Hardware] Computer Hardware Issues

btw, a friend told me that most flash memory has a finite amount 
of erase cycles, which is not very high... this is not an issue for 
using photos, as we usually erase them seldomly, but for things like 
using them for RAM... it could burn them out.  I don't know if usb 
sticks and sd like cards use the same sillicon inside though.

I've been thinking about getting a CF card to IDE adaptor and buy 
a 2 or 4 GB CF card, put it in my laptop and find a small Linux distro 
that doesn't use swap.

Does anybody know how I can find out if a network card is removable 
(like PCMCIA, USB (does this exist?))?

you mean - by some system query?

hmm, dunno ... you can get list of devices somehow, but if there 
are any parameters, I don't know. Generally, you can check with free 
products as Everest, they pretty much disclose all possible hw info 
and categorise it. Cool app. If Everest or othere such sw does not 
disclose such info, then I am not sure it si possible.
but maybe some Win32API guru will tell us more.

flash memory has a finite amount of erase cycles

 ... from memory [no pun intended] it used to be about 200,000 cycles, 
 raised to 2,000,000 or so cycles in current generation flash technology. 
 Note that flash drives try to distribute writes evenly across the 
 media and mark areas as unreadable once they approach/exceed certain 
 thresholds. Nothing wrong with using flash as a swap device as long 
 as it's doing several swaps an hour not several a second! ;)

2007 has been tough on my hardware -- first my iBook hard disk croaks, 
now my PC (following a brief power outage) decides it no longer wants 
to switch on.  It lights up for a second, then powers down again. 
 I don't know where to start (power brick, motherboard?)...

power supply
most likely thing to fail in any pc barring the hard drive
I've seen the symptoms you describe quite a few times.  All solved 
by replacing the power supply.

I've had problems with power supplies in PCs, so that's a good guess. 
Make sure you have PSU, that can pull make watts.

Did the power outage damage your power supply.
was it a spike ?

pull many watts

Watt ?

Effect is measured in Watt. (My english isn't the best this late 
at night.) :)

So, Chris, you have a hard drive failure followed by a power supply 
failure.  It's common.
Don't take it as though the universe is against you ...
but if it keeps happening .. you might want to see how clean your 
power is .. and invest in surge protectors
Chris

The universe *is* against me.  Don't try to suggest otherwise...
I wasn't around when the outage happened.  It was plugged into a 
surge protector.  However, the power supply is around 6 years old 
and the fan quit late last year.

Perhaps I can offer an alternative to that universe question?  I 
personally know the guy who made it.  : ) C'mon guys, I couldn't 
resist. 

OK, back to hardware.

Ok, pulled out the brick and cables.  It appears to be 250W ATX/ATX12V 
with a 20-pin connector, 5 peripheral (Molex?) connectors and 2 floppy 
connectors.
When looking for a replacement, can I ignore the ATX and just go 
for ATX12V?  Or one with a 20+4pin connector?  I'm thinking 400-500W.
(I hate shopping around for this kind of stuff)
Graham

If you purchase a ATX 2 power supply with 24 pin power connector, 
ask them to give you a free adaptor to turn it into 20 pins.  The 
ATX 2 power supplies normally have cables for SATA hard drives
Chris

Is that ATX1V 2.0?
ATX12V 2.0
Graham

I just know it as ATX 2.0

Are these very fast speeds for %server-speed.r :

It's considerable better than REBOL.org -- which runs on the original 
8086 chip as far as I can tell :-)
