This is my motherboard: ASUS M4A89GTD PRO/USB3 AM3 AMD 890GX HDMI SATA 6Gb/s USB 3.0 ATX AMD Motherboard The board has two PCIe 2.0 x 16 slots. The first one (the white-colored panel) is only meant to be used with a single VGA card in the 2nd slot (the blue panel), or in CrossFire. PCIe 2.0 x16_1 slot (gray, at x 8 link) PCIe 2.0 x16_2 slot (blue, single at x 16 or dual at x8 link) Reading through my mobo manual, it told me to install the VGA Switch card in the first slot and to install my single VGA card in the second slot so that I can use the x16 speed, instead of just x8. "For working at x16 speed on the PCIe 2.0 x16_2 slot (blue), it is necessary to install the bundled VGA switch card to the PCIe 2.0 x16_1 slot (gray)." So, that is how I currently have it configured. I have never installed the card in the first slot, nor do I have any previous experience with different PCIe 2.0 slots, so I don't know whether doing so would be a mistake or not. On a side note, the page before it lists the IRQ assignments for the motherboard, and now it makes sense why disabling my JMicron Controller has seemingly solved my problem: ...............................................................|.............C ..................|................D.................| PCIe x16_1...............................................|.................................|...........Shared..............| PCIe x16_2...............................................|..........Shared.............|...................................| Onboard 890GX Video Controller................|..........Shared............|.....................................| Oncip SATA Controller...............................|................................|..............Shared.............| Onboard JMB 36x SATA Controller..............|.................................|...........Shared...............| I have 8 USB ports. Two 2.0 ports on the top front area of the case, four 2.0 ports and two 3.0 ports on the back. My Logitech Webcam is on IRQ 17 (Standard Enhanced PCI to USB Host Controller) However, any port that I connect my mouse and keyboard to use the Standard OpenHCD USB Host Controller, which shares IRQ 18. I'm guessing that the port detects what type of device it is and the appropriate controller takes ownership of it. So, whatever port I connect my Webcam to will always use the Standard Enhanced PCI to USB Host controller, which has no conflict with IRQ 18. To answer your first question, however, I don't believe any of my drives are connected to the JMicron controller. I disabled it last night with no issue and since then have not encountered any system interrupts.

My mistake, I did not realize that there were two separate files and that there was a difference between them, because they both look identical. I just recorded another occurrence of the issue, so this will be an entirely up-to-date version. I have uploaded the DPC_Interrupt.etl file and I will send you the link in a PM. Sorry for the mix up, this a bit new to me On a side note, I just found out that my 560 Ti shares the same IRQ as my JMicron JMB36X Controller drivers, though they both state there is no conflicting issue. As far as I know, isn't it extremely inappropriate for two drivers to have the exact IRQ? In fact, just had ANOTHER issue, so I went straight to the JMB36X drivers and disabled them. As soon as it accepted them, the issue stopped. I'll coast around and see if any issues occur again with this disabled.

Hi Andre, I've known about this thread for a few months now. From all of the searching around I've done about this issue, this seems to be the only way to try and get a definite answer. I am currently uploading my DPC_Interrupt.etl file (named "kernel.etl") to a site that allows over 300MB file uploads. I did the process you explained in your first post several months ago and obtained a 1.4GB file showing a few minutes of regular CPU usage and then a massive spike due to System Interrupts at around 600 (6 minutes?). To briefly explain, ever since I installed my new EVGA GTX 560 Ti 1561-AR model GPU, I've been experiencing System Interrupts on a very often basis. It seems to be triggered by anything, whether I'm playing a game like TESV or Garry's Mod, or even if I just booted up. I started a thread over at the EVGA forums to try and get some help but didn't receive much in experienced assistance. If you would like to take a look, I elaborated extensively on the problem that I was encountering over the course of about a month, back in December/January. Here is the link: EVGA Forums Thread I know without a doubt that the System Interrupts are directly related to the 560 Ti because it only happens whenever I decide to reinstall it. By the time I get sick of it, I uninstall it and put my ASUS EN9600GT 512MB card back in, and the problem stops. What's even more disappointing is that the problem still occurred right from the boot after I completely reinstalled Windows 7. There was a period of time that I was able to play on the 560 Ti for nearly a week or more without issue after performing a clean boot. However, the day I decided to restart my computer for some updates, the issues came right back, and I haven't been able to replicate that temporary solution. It's been a long search with only disappointment. I simply want to use my new video card without issue. I will be PM'ing you the link to my kernel.etl file. If you take the time to give it a look, I will be deeply appreciative. I am on the end of my rope and don't know where else to turn.
