Izginuli spomin v Win 7

Kam za vraga je izginil spomin v Win 7 (64-bit)?
Sistem uporabljam že več let, nobenega HW posega ni bilo v škatli. Relativno čist računalnik, posodobljeni legalni Win.
V zadnjem času sem opazil silno mletje po disku in prejle sem malo pogledal po sistemu. Glej zlomka:
Kaj za vraga mi je vzelo 2 GB?
Nobenih sprememb v BIOSu, naredil sem "memory test" in pokaže, da je vse ok in sporoči podatek 4 GB.

Odstranil sem gonilnike za grafično kartico in jih bom sedaj ponovno namestil (ko se pretočijo do mene :-)). Ideja je tudi skok v Safe Mode.

Še kaj drugega?

Novi gonilniki za grafično niso spremenili slike.

Mogoče bo ponovna namestitev res edina rešitev. Ampak kaj se mu je zmešalo?

lahko tudi probaš bootat iz usb kak ubuntu da vidiš če ti tam sploh dela.. tukajle imaš navodila za naredit usb

Katero os. ploščo, procesor, grafično imaš ?
Saj ti winsi najdejo ves ram (4gb).
Mogoče gre 2gb v SuperFetch.

Hardware Reserved

Beginning on the left, in gray, is the Hardware Reserved list, which shows the amount of memory reserved for hardware. This list represents the amount of memory that the various hardware devices installed in your system have reserved so that they can communicate with the operating system. Of course, memory reserved for hardware is essentially locked and as such is not available to the memory manager.

Typically, the amount of Hardware Reserved memory ranges from 10MB to 70MB but can vary depending on the system's hardware configuration and might be several hundred MB. Examples of components that can affect the amount of memory reserved include:

System BIOS
Motherboard resources, such as I/O advanced programmable interrupt controller (APIC)
Sound cards or any other devices that require memory-mapped I/O
PCI Express (PCIe) bus
Video card
Various chipsets
Flash devices
(Some folks have reported inordinately huge amounts of memory being allocated to the Hardware Reserved list. While I haven't encountered this situation myself and can't verify the suggested solution, many have reported that upgrading the system BIOS firmware solved the problem.)

Še tole preveri:

Preveri tudi če obstaja kak nov bios za tvojo ploščo.
Če ne veš katero imaš, odpri stranico.
Start meni, run -> dxdiag ali cpu-z bi tudi pomagal http://www.cpuid.com/softwares/cpu-z.ht... .

Če je bil RAM do sedaj zaznan normalno, posodobitev FW ne bo rešila problema. Če že, resetiraj BIOS (uporabi jumper). Testiraj tudi vsako palčko RAM-a posebej.
