Ok going to throw this out as a preliminary post.
Over the past week my PC has developed an irritating fault ........... the keyboard and mouse have developed lag (delay when typing, pointer freezing and then catching up).
Some audio crackle and drops in FPS when playing games.
When running a game sometimes the keyboard becomes totally unresponsive.
Replaced keyboard and mouse, still same problem ...... updated and rolled back drivers, still same problem ......... reinstalled windows (3 times), still same problem.
Temps are well within range (around 50 - 55 c max GPU and around 60 c max CPU).
Memtest showed no errors, SSD's are in perfect health, voltages are fine.
After much head scratching and investigation I came across high DPC issues as a possible cause of the problems ...... installed latencymon which I ran while running tasks and hey presto ..... it reports that the values are high to cause issues with real time audio while running other tasks.
The GPU value was high as was USB.
Have disabled things, enabled, typed in commands in cmd prompt and all other suggested fixes ....... no fix.
****** are to refund the motherboard (z77a-g45, 5 months old) and if a new board does not fix it then I will need to rma the graphics card (gtx670, 1 year old).
Do any of you guys have any last minute advice before I go though the rma process? I am so ****ed off I am really am considering selling it once I get the new / replaced gear back.
