Ciao, sono nuovo del forum, e ho un problema con il mio portatile.
Il pc è un notebook dell m4400, tutti i dati che sono riuscito a reperire li ho salvati nel mio profilo, se serve altro ditemelo che provo a reperire le informazioni aggiuntive.
In pratica lanciando DPC latency checker vedo che spesso sono sul giallo, e ogni tanto appare una barra rossa enorme, quindi suppongo ci sia qualcosa che non va.
Come suggerito nell'ultimo messaggio ho lanciato anche latency mon, ma non mi da delle informazioni semplici da interpretare, nel riassunto però mi dice:
codice:
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. The cause of the problem is not immediately apparent.
LatencyMon has been analyzing your system for 0:01:38 (h:mm:ss)
Il problema che ho è che ho provato a installare mediaportal su windows vista e ho notato degli scatti nella riproduzione sia del video che dell'audio.
Ho fatto ulteriori prove con diversi software e con tutti ho avuto lo stesso problema.
Con latency monitor ho provato a disattivare diversi dispositivi, sia uno per uno che tutti assieme, ma non sono riuscito a trovare la fonte del problema.
Su questo pc è installato anche linux, e li non ho nessun problema, quindi tendo a pensare che il problema non sia dato dal bios (anche se come detto non sono un esperto).
Potete darmi una mano a interpretare i dati ricevuti da latency mon?
