    Whenever I do anything with a large file (copy, open archive, etc.) my ram slowly fills to around 98% and everything slows down to a crawl. I tried the same files on other computers, but that doesn't happen there. I also tried reformatting my computer. That didn't work ether. Is there any solution to this?

    Very rare that you would hit 98% of 4GB in the first place!

    in task manager.. when this happens show us a pic of performance tab(shows ram+cpus)


    You can test if is the anti virus by temporary disabling it via tray icon)

    also turn off (in avast) real time file shield.. off=scan when writing(i turn this off its not needed slow things down) (expert settings)


    with avast . recommend also(from clean install v6.xx) when installing turn of sandbox+ behaver shield..

    also after installed.. in expert setting turn of sandbox in file shiled(above)

    + turn off auto update of main program(if it does this it install it again).. just leave the small auto updates

    I can verify this, as long as you're moving something like 20 GB, Windows seem to like to fill up the RAM to absurd percentage of RAM (assuming a memory leak here). It also fills up 8 GB of my RAM from time-to-time.

    Tried turning off Avast, no effect. Here is screenshot of the performance tab.

    How big is your pagefile?

    Also, the 8 Chrome instances running alongside games can't help.

    @OP

    The tasks in your task manager add up to a bit over half a gigabyte of used memory. Something else is using it. I've got 6GB of memory, with ~500mb used by tasks listed in the task manager (Firefox open...). 24% of total memory is used, which leaves

    0.24 x 6000 - 500 = less than 1GB for that "something else". In your case, that's 3.5GB. Over 2.5GB more is utilized than should be. To me, it sounds like Windows is bugging.

    I would recommend this: go to msconfig and choose "Diagnostic startup". Then go to safe mode, try copying large files and see if the problem persists. If not, go back to msconfig and choose "Selective startup", and check the box "Load system services" and uncheck the box "Load startup items". Then reboot to safe mode and repeat the experiment. If the problem is not there, go back to msconfig and start enabling the startup items in the Startup tab one by one, testing and rebooting between each of them. This allows you to systematically find out which process is responsible for the problem.

    This problem sounds like the infamous Windows disk cache bug. Affects everything that needs to read lots from disk. Windows thinks it needs to fill up ram. You can do this by running a torrent program with many large torrents downloading.

    Or just keep Firefox or Chrome open for a couple of hours and you'll end up with the same thing, because of memory leaks.

    using vista or win 7, it loads up + uses 2.5-3g ram.. not much left from 4g, you need 2-2.5g for games, + 1g for multi browsers... depends pon whats runing.. the o/s will use page file(hdd) as ram...

    windows will use less ram if you have less ram though.

    @OP - is that screenshot accurate? because its not quite adding up to 4gb... cant really tell whats hogging your ram from that.

    That is precisely my problem. I can't see where it is going so I can close that process.

    I already mentioned where it is going: the disk cache that windows allocates for file transfers. All documentation states that the max is 8 MB with LargeDiskCache disabled but in my own experience, windows will take as much as it wants, thus slowing down the system greatly since it starts dumping to the page file instead.

    Microsoft does not see this as a problem, since I have reported the issue to them in the past. Most people would agree with them that inefficiently using up all their ram is good, since it is making use of all those gigabytes of ram they have installed on their machines. The problem affected my previous main build with 8 gigs as well.
