Hihg latency problem

[fickomen]

Hello,i've been trying to solve this problem for over a month.First,i've noticed that in call of duty 1,where i had 333 fps, it felt like 30.Then i used Latencymon for test,i'll post the results.
My pc components(pretty low,but cmon its call of duty 1):
cpu:Intel Pentium Dual CPU E2140 1.60GHz,
RAM:2GB,
GPU:Nvidia GT220,
MB5LD2-X/1333,
HDD:Toshiba P300 1TB,
Windows 7 64-bit,
Things i've tried:
1.changed hdd,
2.clean instal of windows 7(i had 32bit now 64),
3.replaced thermal paste on both cpu and gpu,
4.pluging and unpluging almost every cable inside the pc,
5.uninstalling antivirus,
6.updated drivers via driver booster 6,
7.rolled back some drivers(display,network,and sound),
8.<<<<<nvlddmkm latency went down by disabling display driver,but there must be another way>>>>>
Things i haven't tried:
1.updating BIOS,
2.changing anything in BIOS,
I'm facing stuttering in every single game i try to play(cod 1,lol,cod2,gta vice city,minecraft)despite playing with the lowest possible graphic settings.Help me please .Check the results.
The following results are from testing the pc on idle:

CONCLUSION
_________________________________________________________________________________________________________
Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
LatencyMon has been analyzing your system for 0:01:37 (h:mm:ss) on all processors.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

Highest measured interrupt to process latency (µs): 4865.920
Average measured interrupt to process latency (µs): 5.101069

REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.

NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.

Process with highest pagefault count: latmon.exe

With 2 gig of ram on a win7 64 bit OS is your problem.
The hard drive has become your memory, or virtual memory.
Windows must constantly swap what is needed in and out of memory to the hard drive.
You need at least 4 gig of ram, and then you will still see some slow downs .
