Help! Windows-7 is eating all my ram.

hello i am using windows 7, everytime i start up a game i can play for like 5 minutes and then my ram is at 90% i've got 4gigs of 1066mhz, then i quit the game and wait for like 15 minutes and then its using 20% of my ram, it happends with all my games. will it make any differents if i reinstall win-7. if not please tell me what to do.

my components :

2x2gb ocz 1066mhz memory
sapphire pure corssfireX 790GX + sb750 chipset
sapphire hd radeon 4850 512mb
AMD athlon 7750 - 2700mhz

yeah all games, but when i look in the task manager its not there so i dont know its just something that comes and goes dunno what it is (((

It sounds to me like you're seeing the results of Superfetch. It's role is to pre-load into memory program and library files it thinks you may need - that way when you come to use them you don't have to wait for them to be loaded from disk.

You could try turning off the Superfetch service to see if it makes a difference. But the pre-fetched stuff isn't hurting anything, if it's not needed it will yield the memory to whatever requests it - so having that memory used is probably not something to loose any sleep over.

Technically, variables vary in size depedning on their type, but a 32-bit integer is 4 bytes (32/8=4), and a 64-bit integer is double that (8 bytes: 64/8 = 8)). So actually, a 64-bit OS would use MORE space for integer variables.

Of course, most languages could simply use either the Int16, Int32, and Int64 (or equivalent) calls as needed to ensure the proper size and scope is used, instead of the generic Int (which is compiled based on the OS support in most languages...). Example: If you have an integer that will always be <255, there is no reason for it to be any larger then 1byte (8bits = 0-255) in size, so using a 64-bit int in that situation does nothing but waste space.

Of course, there is a compatability layer in both compilers and the OS. On a 64-bit Windows system, all 32-bit programs go through a compatability layer to work properly, but usually this doesn't affect memory usuage much. Of course, the X86/X87 arch is fully backward compatable, so regardless of size, the CPU can handle and send back that data, regardless of OS support. Most of the gains of the 64-bit arch, performance wise, are the result of the CPU's full register set being open, and as the result of a higher celing on installed RAM/devices.

disabling the superfetch didnt work

notice: 3 weeks ago i built my this pc, after 2weeks my pc started doin what its doin today. could it be some program starting and then closing ?

thanks for helping this 'noob (me)'

You need to see what all is running in the background, could be any number of things using up the memory. But, as already stated, why is this a problem?

OP - You need to figure out what is using all that memory. To be honest, the issue sounds more like a memory leak than anything else. Contrary to popular belief, Superfetch is a lot more 'polite' than what you're relating.

Reach out and grab a copy of Process Monitor. It's basically Task Manager on some decent steroids and provides the ability to drill down into what is the program behind generic process - svchost being an example of a generic process that comes up a lot in posts. "OMG!! svchost is killing my computer!..." whereas it's really a 3rd party program/driver that's causing the issue.

when i play my games i have like 40 fps in farcry 2, but when the ram thingy goes on i get 15 fps.

OK - What you can do now is kill that process, or remove the app, and see does that solve the issue. If so, then sweet! Look for an updated version or alternative program that works.
