Pc com spikes na area de trabalho e reinicializações

Recommended Posts

Meu computador tem travado recentemente, com alguns spikes na área de trabalho, e durante a utilização de alguns programas. Foi recomendado a utilização do LatencyMon para buscar a solução dos problemas, só que em nenhum fórum a ajuda dada funcionou.

segue abaixo o resultado do LatencyMon:

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 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 0:17:23 (h:mm:ss) on all processors.

SYSTEM INFORMATION

_________________________________________________________________________________________________________

Computer name: ADRIANO-PC

OS version: Windows 8 , 6.2, build: 9200 (x64)

Hardware: ASUSTeK Computer INC., M3A78

CPU: AuthenticAMD AMD Phenom 9950 Quad-Core Processor

Logical processors: 4

Processor groups: 1

RAM: 6143 MB total

_________________________________________________________________________________________________________

CPU SPEED

_________________________________________________________________________________________________________

Reported CPU speed: 2613,0 MHz

Measured CPU speed: 3730,0 MHz (approx.)

Note: reported execution times may be calculated based on a fixed reported CPU speed. Disable variable speed settings like Intel Speed Step and AMD Cool N Quiet in the BIOS setup for more accurate results.

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): 31014,766156

Average measured interrupt to process latency (µs): 6,137713

Highest measured interrupt to DPC latency (µs): 571,742294

Average measured interrupt to DPC latency (µs): 1,622833

_________________________________________________________________________________________________________

MEASURED SMI, IPI AND CPU STALLS

_________________________________________________________________________________________________________

The SMI, IPI and CPU stalls value represents the highest measured interval that a CPU did not respond while having its maskable interrupts disabled.

Highest measured SMI or CPU stall (µs) 4,702473

_________________________________________________________________________________________________________

REPORTED ISRs

_________________________________________________________________________________________________________

Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.

Highest ISR routine execution time (µs): 330,701875

Driver with highest ISR routine execution time: ataport.SYS - ATAPI Driver Extension, Microsoft Corporation

Highest reported total ISR routine time (%): 0,018610

Driver with highest ISR total time: USBPORT.SYS - Driver de Porta USB 1.1 e 2.0, Microsoft Corporation

Total time spent in ISRs (%) 0,035017

ISR count (execution time <250 µs): 265834

ISR count (execution time 250-500 µs): 0

ISR count (execution time 500-999 µs): 69

ISR count (execution time 1000-1999 µs): 0

ISR count (execution time 2000-3999 µs): 0

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

_________________________________________________________________________________________________________

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.

Highest DPC routine execution time (µs): 990,518178

Driver with highest DPC routine execution time: ntoskrnl.exe - NT Kernel & System, Microsoft Corporation

Highest reported total DPC routine time (%): 0,170895

Driver with highest DPC total execution time: USBPORT.SYS - Driver de Porta USB 1.1 e 2.0, Microsoft Corporation

Total time spent in DPCs (%) 0,503744

DPC count (execution time <250 µs): 3860582

DPC count (execution time 250-500 µs): 0

DPC count (execution time 500-999 µs): 971

DPC count (execution time 1000-1999 µs): 0

DPC count (execution time 2000-3999 µs): 0

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: svchost.exe

Total number of hard pagefaults 11879

Hard pagefault count of hardest hit process: 2854

Highest hard pagefault resolution time (µs): 2702218,081133

Total time spent in hard pagefaults (%): 6,221247

Number of processes hit: 36
