Windows 7: Most Windows 7 PCs max out memory.

That's backwards once useage is past a certain point. Opening new programs with high memory utilization already occuring will require more memory INCREASING HDD useage as the system has to resort to the swap files to meet memory requirements.

True - What's needed in order to maximize both sides of that particular situation is some intelligence in the OS which can keep track of which programs the user is likely to launch; and at what days/times. From there, it's simple to manage what is cached and when.

I wonder what OS can do that??

That's what Superfetch does to a certain degree. It's "memory" however does not go back days or weeks.

You would have loved the guy I saw on another forum a while ago that complained about the "extra" ram usage in Vista (and now by extension 7), and how the "extra" usage would cause the computer to use more electricity.

As a University of Illinois grad in the big-D curriculum -- Electrical Engineering AND Computer Science -- I firmly claim, and will post all the proof you need, that an average 80mm case fan burns more watts/hour than any modern RAM you have, no matter what the frequency. All DRAM refreshes, no matter if it's set or not. And the bigger the capacity, the smaller the die. Old 256 BIT DIPs use more power than a 4GB DDR3 now just because of the reduction in trace. Voltage used on those old chips would fry even that fan -- in fact old ferrite cores were current-based using over 400mA to keep them charged. That's enough to fry a gnat...

Ever heard of the first computer BUG?

1941 - 1950

Grace Murray Hopper, who lived from 1906-1992, found the first computer bug while working in a temporary World War I building at Harvard University on the Mark I computer where a moth had been beaten to death in the jaws of a relay. She glued it into the logbook of the computer and thereafter when the machine stops (frequently) they say that they are "debugging" the computer. The very first bug still exists in the National Museum of American History of the Smithsonian Institution. The word bug and the concept of debugging had been used previously, perhaps by Edison, but this was probably the first verification that the concept applied to computers.

Oh, and big-D I meant big drop, ask Marc Andreessen, 70% of his class either went insane or left during my era File:Mosaic browser plaque ncsa.jpg - Wikipedia, the free encyclopedia

I have an old PC with 1GB of RAM with XP and Win 7 both 32bit installed and Win 7 always crashes due to lack of RAM.

My grandma's Old PC has 1.5. Windows 7 installed with no problems. So if you can add another 512. that might fix your problem.

Lack of RAM or memory?

That cannot be. There must be another problem. Increase the size of the pagefile. Maybe that can fix it. Also have a look into Resource Manager and see whether you have an unusually high "modified" - it should only be a few MBs.

Also check how many start up programs you have running, if you have a lot, cut them down to the essentials, that will save RAM as well.

That's what Superfetch does to a certain degree. It's "memory" however does not go back days or weeks.
One example of what I'm talking about it: It's impossible to use my laptop to watch a movie stored on the HDD while riding a bus, because instead of reading a few minutes ahead, it reads every 1-2 seconds, and if there's a bump in the road, it freezes for 3-4 seconds. It's also impossible to listen to music stored on the HDD for the same reason. Strangely enough, if I move the media to a flash drive, it works without a single pause. Can't wait til SSDs come down in price. I'd love to be able to replace the HDD with an SSD of the same capacity, but I don't have $900 sitting around

But here the problem is mechanical. When the bus hits a bump, the heads of the disk retract to avoid a head crash. Maybe putting the laptop on a pillow may help (if that does not impede the cooling too much - e.g. if the vents are towards the side). But the flash drive option is a good alternative - even a large SD card (that does not stick out on the side and cannot break).
