    Hey All,

    Could a few people who use G50, G60 and G70 series notebooks run the DPC Latency checker for me and tell me their avg results? or if you've already used DPC before give me an indication of your times.

    I'm using the G60jx-rbbx05 model (i5-430, GTS360m) and it will be smooth for awhile then I'm getting bad spikes all over and I don't have the Synaptics touch pad drivers installed by the way. Sometimes spiking up to 17000 µs which is 17ms and that's pretty bad :/

    I've tried getting rid of everything besides essential tasks in task manager and services too.. even tried disabling network adapters and a few other things like USB controllers and still no luck :( can't seem to keep it smooth green.

    It's really doing my head in.. I can't seem to figure out what is wrong with my laptop. I'll be sitting in the desktop with no other programs running.. run the DPC latency checker and it will be fine and green for a while.. then randomly starts spiking really crazy 4000's at first then up to 18000.. anybody know what I could do to solve this?

    Do you think it's a CPU clock issue? btw I'm using high performance power with my ac adapter plugged in, so processor should be always at 100%

    I find the culprit is usually a hardware driver.

    Try using performance monitor to keep a closer eye on things

    What am I looking for with the performance monitor, btw DPC latency seems to spike high when I have keyboard lag.. but I'm pretty sure the keyboard lag, well lag in general is from some driver. Already uninstalled Synapics but there is still some lag DPC picks up :(

    Monitor any usage on other resources like CPU, RAM and HDD to help pin point the culprit.

    Do you have any real time scanners/AV's or such?

    What counters should I add for example? and real time scanners are like Norton right? I don't have any installed no.

    Just Windows Defender.

    Try Physical disk usage first, see if it spikes the same time as the DPC latency.

    Try disabling Windows Defender too

    There is about 10 different counters inside of PhysicalDisk, which one is the usage.. Sorry for the questions :/
