turbulent flow not bad for cooling by
Timothy Daniels
Some people believe religiously in smooth laminar flow
of fluid past an object to cool that object. But turbulence
actually acts to scrub away the boundary layer of air (or
other fluid) that surrounds the object to make closer contact
between the object and the passing fluid. It is the...

Wireless mouse with longest battery life? by
BestMouse
My system is a year-and-a-half-old Dell Dimension 8400 running WinXP,
with a Dell wireless keyboard and mouse, and is left on 24 hours a
day. Unfortunately the mouse, which requires two AA batteries, uses up
batteries very fast, so I'd like to replace the mouse with a more
efficient one (but keep...

Questions about DDR RAM by
Igor
I'm planning to add some memory to a PC. The motherboard supports "DDR up
to 333 MHz (enhanced) memory bus."
333 MHz (PC2700) or slower DDR SDRAM isn't easy to find on today's market,
and when you do find it, it's considerably more expensive than the DDR
which runs at 400 MHz (PC3200). What...

Actual hard drive space? by
Jethro
I notice there is always a great disparity between stated hard drive
capacity and actual usable capacity after formatting.
Is there a chart or other paper anywhere showing maybe comparisons of
this between drives, and maybe an explanation of why and how it
happens?
Thanks

CPU Cooler designs? by
Gerry_uk
Hi,
As I understand it, most ATX style PC setups have a fan above the CPU
that blows air down onto the CPU to keep it cool, and the hot air
bounces around inside the PC case until it can find an exit (if it's lucky).
As I see it, there are two problems with this,
a) unless you have a vent in...

Need Help With Installing HP 950 PSC AllInOne by
Jethro
Wouldn't you know it!
I have a HP 950 PSC AllInOne (Print/Scan/Fax) that I want to install
on a new machine with WXP SP2.
I can't find the CD that came with it. I've looked & looked.
I tried DriverGuide.com, but all they seem to have are print-drivers
for this printer under the various OS's.

MS
Hi,
I have an old PC which I've just turned into a music machine and (living
room) web access. It runs Win 2000 Pro (just) but everything is very slow
to load and I mean SLOW. The reason is it has just 64MB RAM, but virtual
memory is using about 200MB, plainly I need a RAM upgrade.

PC almost at standstill by
Terry Pinnell[_2_]
This follows on from my post describing a boot up failure, as the subject
heading of that is now misleading.
The consistent state now is that my Athlon XP 1800 PC takes about half an
hour to boot! And then every operation is similarly glacial. For example,
after double clicking My Computer it...

resulting from a cloning of a WinXP system HD

by another OS in the PC.) The hassle is that you
