SLI is the name of nvidia's version of using 2 GC or more for more processing power

a mobo that has 2 pci-e slots does not means it support sli for sure, cos there's also ATI's version, the CrossFire.

and yes, even if u have an SLI or CrossFire board, you can use any cards on it, not necessarily must have 2 GC only can run. any single PCI-e cards will usually works on SLI/Crossfire.

between pc to pc for crossover cable, it's just plugin in to the same network port, and setting up different ip for both computers

crossover cable is strictly for communications between the connected pc, no internet is involved
as for gaming, i think it's possible, as long as u get ur ip settings correctly
i tried copying files from other pc using crossover cable before, just set ur computers to the same ip range, say ur fren 192.168.100.1, urs should be 192.168.100.**

yes, but mainly 3.5" need a standalone ac adaptor, which means u need an extra plug point for it to be powered up
if u are on the go, and using battery alone, 3.5" ext. hdd are not recommended

if not mistaken, highest capacity now is 250gb for 2.5"
bear in mind tat not all casing support this capacity
u need to check with shops for capalang casing
you can obtain information for branded 1s from their site
price breakdown can be obtained from lowyat.net front page price list

it's usually stated in the specs on the box
but before buying just confirm the model online
usually reviews will mention it

wat games you cannot play?
and are u using original vista in the first place?
i dun recall a original vista in ur to buy lists....
i have no problems playing games as old as starcraft on my vista, and a lot here also no problem at all despite the higher requirement for the same game compared to XP

care to provide more details?
we dunno your system specs, how to say if the PSU is adequate or not
also, what GC are u talking about and intended purpose?
gaming, but wat kind of games? solitaire?

nvidia ntune, can get from nvidia's site

blink blink?
wat model and which indicator is blinking?
usually if u call streamyx hotline, they will say if the DSL is blinking it's a sign of ur connection to the server.
or the blink u are talking about is just there to indicate internet activity
provide model and even better a picture of the problem

probably streamyx fault then
call them up
it's probably their server side problem

can detect, but tat's not the true value u can actually uses
read around, posted many times liao la

well depends on wat u mean by compulsory....unless you want ur processor to toast, i say it's pretty compulsory.if u have no problem with toasting ur processor, sure, dun put thermal paste

cos static charge can overload the delicate cpu electronics components lor by overcurrent
but usually, problems like static charge dun occur in humid weather like us, unless u are kinda special and have a lot of static charges naturally

sounds like the resolution u set for the game is out of range of ur monitor
wat monitor are u using anyway?

brand is not a factor, only size and speed
usually ppl just recommend using the same brand as sometimes different brand might have compatibility problem, but kinda rare

u cant get higher directx unless u use vista
dx10 is still vista exclusive

just the partition u want to install with
usually C

no lar, tat means tat card has 512mb of ddr2 on it
graphic card rams has nothing to do with system rams

good as in for wat?

have u tried cleaning the fan from dust?
also, have u taken out the processor before?
if you did, did you reapply thermal paste?

depending on the version
32-bit OS such as windows XP, Vista only support up to 4gb due to limited memory addressing space
but then, the max 4gb also includes some other stuffs such as graphic card rams and some other misc stuffs
64-bit OS can support much higher than that

if the processor attached to a mobo and running?
if yes, u can easily run programs like cpu-z to see
if not, there's also the method of checking the serial code on the processor
