I dunno... anything malicious that changes a setting that UAC would prompt about, I imagine would have a macro or something that would just hit yes on the prompt automatically...
Or detect if uac was on, and go about its changes in another manner.
I'm in the camp that if I have to reinstall every 6-12 months, no worries, as long as I can use my pc in the manner in which I like [ie not being prompted when I do just about anything].

Phil
I must admit that I am dubious about W7 being able to stop a sophisticated attack like the previous one. I also hate being told what I can and can't do by Windows. I guess that I should just make sure that I do more frequent backup images.

Either the automated program wants to run at some ungodly hour when the PC is not normally on, or the automated program, decides to do it's job when you are doing a processor intensive task such as video rendering. A good example of that was the McAfee virus. Alex |

Robert
IF this boastware didn't have numerous fans whizzing around inside it, (17 in G5 !) and I was still working , yes I could be tempted by something with those specifications.However , the sleeker you make something like that , the more internal cooling it normally needs.The problem there is that some stupid engineer decides to control the speed of the fans according to temperature,by penny pinching means such as pulsing the fans at something like 10 impulses per second.
Suddenly , your u beaut low noise fans that you have installed , that were whisper quiet when running at half voltage
on a test bench, and only had an increasing whine at higher voltages, suddenly become noisier than all the rest of the PC !!! With future generation Intel processors,assuming that Moore's law still holds, and the power consumption reduces further, they could be worth a look at.

Alex,
WRT fan noise, was that because on the bench there was no load, i.e. the fans were running in free space and in the computer they had to work by having heatsinks closely coupled to the blades or cavitation?

Robert No, I had the case open, and even with a hand almost blocking the exhaust side of the one on the bench, the noise didn't change much. The 4 Blue LEDs around the Thermaltake fans are a constant brightness on the bench, but can be seen to vary with the same type fan in the PC and cover back on,especially at lower speed. My front HDD fan has a switch to turn it off. Across the switch in the off position is a red LED to remind me to switch the fan back on after ripping. With the fan switched off, this LED can be seen to pulse at approximately 10 I.P.S.when the PC is still cool, and on permanently if fan is switched off for some time. Alex |

Sounds like PWM, fans will be noisy. I run a pair of 120mm in an air box over my AV receiver from a variable DC supply. The fans a very quite from DC at about 7V , but the do make a bit of noise when starting. And yes it's 970 watts input  Without knowing the circuit you could try, add a series R 10R to 22R and a small C 47uf to 220uf across the fan side. The feed back would likely be RPM from the fan and control by thermal sensor both on main board and CPU. |

The feed back would likely be RPM from the fan and control by thermal sensor both on main board and CPU. Robert What I have thought about doing is to use 2 of these Thermaltake fans side by side, as there is a spare position, and run them in series from a normal 12V feed without speed regulation . Going by the fairly low noise level of the bench test fan, and very little vibration at that speed, this should be far quieter, and also give a reasonable air flow without the need to switch the fans off, although this could still be an option. Alex P.S. I wonder how many people would have installed good quality MB controlled fans to their PC, and blamed the fan's manufacturer for the fan's noisier than expected performance ? |

I picked up one of these media players a few weeks back. I went for the sumvision cyclone www.sum-vision.co.uk/productinfo/cyclonemicro/cyclonemicro.html purely as it had good reviews for the price (£25-odd). The first thing that struck me is that it's very small, about the size of a usb hub. Which makes it handy to stick in a drawer when not in use. The main reason I bought it was because I was getting tired of having to convert and burn avi's of TV programs to DVD, just to watch them once (don't mention DVD-RW...). I don't have a fancy TV or DVD player, so just needed something to play AVI. We've been using it the last few weeks, watching the likes of Lost and Caprica, and the kids Chowder and such. I've been very impressed with how simple it is to use, and also how good the picture is (SD) I've not used it for pictures or music, but I pretty please with the little thing, as it does the job I want it two with no fuss. Oh, and in the conversation above about PC/Mac fan control, PWM=  for noise. Variable linear supply is the baby. |

HI Will
It transpired that the fan being controlled from the MB using PWM was noisier than the rest of the PC combined when I had a good listen with the covers off. Fitting 2 of the 80mm fans in series, and using the normal 12V supply gave a more complete coverage of the HDDs, as well as being whisper quiet. The PC is now markedly quieter.
