When I first read the question, I thought you posted this 2 years ago.
rarely an issue might be little comfort to the one person in a thousand (or hundred thousand for that matter) who zaps their system.
I know of a couple of instances where an unlikely static discharge has totalled a CPU and graphics card. The first probably came from the kid's cat that was brushing up against his leg, and the second likely arose from carpet + socks scenario.
Personally I'd rather play it safe and point out the possibility than have to explain to someone after the fact that they were on the crappy end of the probability curve.
If you can't find an electronics store that sells contact cleaner or canned air, you can probably try toy/hobby shops (some airbrush owners use canned air if they cant afford a small compressor) or a general hardware/plumbers supply outfit. If you are planning on cleaning the CPU cooler only then a local garage/workshop/gas station that has a compressed air line is fine-just take the usual precautions when refitting the cooler to the board. What you can't use that cleaning method for is dust buildup in graphics card/chipset cooling fins and removing dust and dirt buildup from PCB's.
Well, I always include advice on static everywhere I go. But truth be told, I don't follow my own advice here. The only thing I do is to make sure my big toe is constantly touching my case, which takes care of most static issues.
I don't go the whole shebang, including the voodoo ritual and animal sacrifice which I recommend to everyone, just because Murphy's law states that it'll be an ambulance chaser who gets his HDD (of all things) fried, and his company lost all their priceless data, and will chase me to the ends of the earth for my firstborn.
Poor Y3KUZA MOB's thread has been dragged so far off topic that he's stopped posting in it. Maybe we can get back on it so it will be more useful to him.
I apologise once again for taking this thread so far off topic. However, as DBZ had pointed out, the OP vanished a long time back.
Thank you for all the help guys. I won't be posting any of my other queries here.
