Then I replaced the SDD drive, but it still didn’t solve the problem.which got me thinking a video card re-bake may help. For some strange reason, this only made my fans spin at full blast, and my computer would go to sleep every 27 seconds on the nose, very annoying, but the restarts were more intermittent and not as repetitive. I replaced the power supply with the one I bought from iFixit, but that didn’t work either. I upgraded the RAM from 20gig to 32, that didn’t help. I tried everything that others have tried( PRAM/SMC reset, Disk Utility from Recovery, erasing the SSD drive, reinstalling the OS, RAM modules, Power Supply from iFixit was ordered in hopes that was it. I encountered this same issue a month ago with my 27” Mid 2011 3.4gig I7 iMac 6970M 2Gig video card, 32gig ram, with a split FusionDrive( 2TB HDD/250 Samsung Evo850 SSD ). I had to remove its wifi card to solve it. I suspect the fault is with the WiFi card as I recall having a similar problem with the wifi card in my old 17” 2006 model macbook pro. With the WiFi and infrared cards removed, my system is now stable. Previously, I has disabled the WiFi via the Operating System without result. Finally, I put my original logic board back in and this time I physically removed the WiFi card and InfraRed Card. Further, video testing and memory testing apps always proved the hardware was good. All with no positive effect - the rebooting fault persisted. I also swapped various certified sodimm memories and I even replaced the logic board. I tried installing a different brand (WD) new SSD and worked upwards from Yosemite to High Sierra. However, after a few self initiated reboots the iMac would be stable as long as I kept it on. It would reboot several times after Sleeping or if powered on. My iMac (27-inch, Mid 2011) had the same rebooting problem. They may need to service your homes power feed or replace a transformer that feeds your neighborhood. Have them put a power monitor in your house for a good week or so. You could ask your utility provider to test your power: Many of the better units have power meters which can show you how good/bad your power is. You may need to get a UPS to stabilize the power as your power provider maybe having problems giving you reliable power. So we went as far as the fuse/breaker panel and we still have problems. Many people put electricians grease on the exposed surfaces of the connections after wiring it up to help prevent corrosion. The rod can also have degraded and may need to be replaced or positioned in a better location to be effective. Over time the wire and/or the connection point corrode (green stuff) and need to be cleaned. Often a grounding rod stuck into the ground or strapped to the metal water line feeding the building. Make sure the buildings Ground circuit is in good shape. Following the wiring back to your fuse/breaker panel make sure you have a 20Amp circuit for 120volts and ideally you should have a dedicated line for your computer and your peripheral gear. Even still you do need to make sure the outlets wiring is correct (don't cheat here, you need all three wires). This is were you will need to call in your local electrician to fix the outlet. You could also have a grounding issue if you don't have a three prong outlet. Given the fact the Apple tech couldn't get it to fail when he had it I suspect your issue is within your homes power not your system.įirst you'll need to get a cheap AC Outlet Tester to check your outlet to see if the the outlet is correctly wired. I believe this is a problem with my debugging host, but have never run intothis kind of problem before.I think you started down the right path as being a power issue. Packets are getting dropped by WinDbg on the host. And there's only one target that I'm debugging. Yes, the key that I enter is what I configured the target for. Run nslookup 10.0.0.102 from a command prompt to get the machine name. ![]() Also make sure you don't have multiple target machines pointed at the same network port on your host. Please make sure the host and target encryption keys match exactly. Shutdown occurred at (Fri May 6 08:34:33.724 2016 (UTC - 7:00)).unloading all symbol tables. The target machine restarted without notifying the debugger. KDNET received an out of sequence ping packet. ![]() Microsoft (R) Windows Debugger Version 6.567 AMD64Ĭopyright (c) Microsoft Corporation. But suddenly, I get the following errors when I try to connect to the target system: I have been debugging successfully for some time. Both the host and target are running Windows 10 10586, and are in the same subnet.
