Hi
I dont know if this is the right place,but im desperate.I'm dealing with high dpc latencies i've been trying to solve for over a month.I'm experiencing low fps and fps drops (but without any sound problems) in games that should work perfect with my components(games like cs 1.6,cod 1,LoL).I tried installing new windows 7 32-bit,updating drivers and rolling back them,scaning for virus,turning off antivirus and firewall,disabling stuff in bios,disabling display adapter,network adapter, no success.My components:
CPU: Intel Celeron E3400 2.40Ghz
RAM: 2GB
GPU: AMD Radeon HD 6570 1GB
MB: MS 7592
LatencyMon results:

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. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. 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 0:56:27 (h

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): 42225.829854
Average measured interrupt to process latency (µs): 10.974872
Highest measured interrupt to DPC latency (µs): 191.015422
Average measured interrupt to DPC latency (µs): 1.110874
_
REPORTED ISRs

Driver with highest ISR routine execution time: ataport.SYS - ATAPI Driver Extension, Microsoft Corporation
Highest reported total ISR routine time (%): 0.053432

Total time spent in ISRs (%) 0.083501

REPORTED DPCs
_
DPC routines are part of the interrupt servicing dispatch mechanism and disable the possibility for a process to utilize the CPU while it is interrupted until the DPC has finished execution.

DPC count (execution time >=4000 µs): 0

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: explorer.exe
Total number of hard pagefaults 62550
Hard pagefault count of hardest hit process: 31160
Number of processes hit: 18
