enzity Posted December 7, 2012 Share Posted December 7, 2012 Hi andre, i registered to this board just cause i figured you have just the tools i need. To start things of, lately i've been having wierd spikes in game with around 0.2s freeze every now and then (much like microstuttering, but not quite), so i checked my resource monitor and i noticed something i've never seen before; System interrupts process. Now i understand this is bad, and i believe you have the solution for me!I tried both LatencyMon and xperf but since i didnt quite catch what to look for it didnt do much good for me, so here i'll upload the .etl file for you to look at!DPC_interrupt.zipMy specs:i5 2500kGeForce GTX 6708GB Corsair 1600MHz ramFractal Design Integra 650WMSI P67A-C45Usb devices:SteelSeries Xai (Mouse)PS/2 Devices:Qpad MK-50 (Keyboard)Thanks in advance! <3 Link to comment Share on other sites More sharing options...
MagicAndre1981 Posted December 7, 2012 Author Share Posted December 7, 2012 I have problems with my battery but it didn't make my computer laggy before. It even shows a warning when I boot the PC but I don't have money to buy another one and also I can't see the connection; if I remove it it will solve the high cpu usage?yes, disable the battery or remove it and only use AC power.I tried both LatencyMon and xperf but since i didnt quite catch what to look for it didnt do much good for me, so here i'll upload the .etl file for you to look at!DPC_interrupt.zipyou have ISR (interrupt) spieks of the ataport.SYS driver. Do you run all your drives in AHCI mode or do you use the IDE mode? Link to comment Share on other sites More sharing options...

Do you run all your drives in AHCI mode or do you use the IDE mode?Now that you mentioned it, i did have a overclock malfunction not to long ago and had to reset cmos, and it seems it reverted the drives back to IDE mode, i swapped back to AHCI again but the process is still there However im playing BF3 right now and it dont seem like i have the stutter anymore, will edit if i notice it again.edit: nope, it's not gone. What i've done up til now was changing back to ACHI mode, swapped the drives SATA ports a couple of times. I also tried resetting CMOS and immediatly put the AHCI mode on, no progress either... MEHHHHHHWhat can i possibly try now ? I'm considering doing a fresh install, but i'm pretty scared it wont make a difference. What would you do in this situation? note: In idle, the System Interrupts is no more than 0.5-1% usage on average, but when i play games that 1% bumps up to 3% and its all on Core0 which makes the game stutter from time to time... Pls halp! Edited December 8, 2012 by enzity Link to comment Share on other sites More sharing options...
Furyclaw Posted December 7, 2012 Share Posted December 7, 2012 Hey Andre!I'm running into some issues with my system and I am starting to get desperate. I've been trying to fix this issue for the past 4 hours without any luck. I've managed to locate that my ACPI.sys file is getting DPC errors a lot. So far, I've tried: Updating everything Windows wanted to update.Tried (Unsucessfully) to update BIOS. For some reason it just won't flash. I've tried all 3 power modes that come with my system. All 3 power modes that come with Windows. Have tried updating all drivers I could find, but they all come back up to date. Here's my Xperf file, hope you can make some use of it, as I just can't. http://www39.zippyshare.com/v/28911232/file.htmlWin7 64Bit.i5 3770k16Gb RamGtx 670(Note: I will be at work until 2PM GMT, so no rush in responding until then.

Furyclaw Posted December 8, 2012 Share Posted December 8, 2012 Hoping this file I just recorded using the program can be of any assistance, as I won't be available for many hours Thanks for the help so far. http://www26.zippyshare.com/v/3596680/file.html Link to comment Share on other sites More sharing options...
MagicAndre1981 Posted December 8, 2012 Author Share Posted December 8, 2012 it works fine for me. copy and paste the complete command into the command prompt Link to comment Share on other sites More sharing options...
MagicAndre1981 Posted December 8, 2012 Author Share Posted December 8, 2012 @Furyclawwe posted the same time.The new tarce shows you have high CPU usgae caused by he ACPI driver. ACPI.sys!OSNotifyDeviceWake looks like Windows has issues to enable devices after they were send to sleep. so disable the powersaving options in device manager for all devices.

Furyclaw Posted December 8, 2012 Share Posted December 8, 2012 @AndreI will definately try that out when I get home. Power management is getting to be an annoying thing in this new rig.Will get back to you with the results. Thank you for your patience and expertise.

Furyclaw Posted December 8, 2012 Share Posted December 8, 2012 Not many good news I came home and tried to disable power saving on all my units that had the option in Device Management. This didn't have any difference. I also managed to get my bios updated to the newest version available on the website, but this also have not proved useful.Still sitting at 33-36% CPU usage when just having a webpage up. are there any more steps we can do to resolve this?

Revolt Posted December 8, 2012 Share Posted December 8, 2012 yes, disable the battery or remove it and only use AC power.I removed it and the CPU still remains at a minimum of around 60% Link to comment Share on other sites More sharing options...

Furyclaw Posted December 8, 2012 Share Posted December 8, 2012 I've just installed a brand new copy of Win7, in a desperate attempt to make this s*** work. Can barely play BF3 with this rig at 1368, Low Gfx.Same problems are occuring, but might have moved location. Hopefully you can help. Working on installing new drivers as we speak. http://www40.zippyshare.com/v/87667420/file.html Link to comment Share on other sites More sharing options...
MagicAndre1981 Posted December 9, 2012 Author Share Posted December 9, 2012 it is the same APCI issue again. ry to switch to the powerplan "High Perfomance". this disables the power saving options. Does this fix the issue? Link to comment Share on other sites More sharing options...
