A CPU 100% used by the core - System Idle shows nearly 100%
Almost every day after execution, for several hours, my computer will slow down to where Visual Studio is almost unusable. When I go to the Task Manager, it shows one CPU maxed out. When I go to the process tab it shows that System Idle Process is anywhere from 87 to 94%. When I turn the Show kernel times a CPU becomes completely red. When I go to the overview of the resources there is no activity for page memory faults, no network activity and very little disc activity (0 KB/s up to 5 = 48 KB / s). Any idea of what is causing all my cpu to be gnawed by the kernel? Is it possible to find out more details on what process kernel does this?
Thanks for all the great links, I don't know that I'll use them in the future. However, even if I had no proof, I decided to replace the hard drive. I cloned the existing hard drive (so all the problems of software remains the same) and the problem is now gone.

Why when I try install Mac Os Yosemite in VMwareplayer when the virtual machine starts, I get this error:
The CPU was displayed by the operating system of Fords. Power off or reset the virtual machine
I have an AMD A10 processor
VMware does not support the operation of Mac OS X in VMware Player/workstation! Also, legally virtualisables versions of OS X running in a Virtual Machine can be done when done in the Apple brand hardware but when done while running under OS X, and for that, you need VMware Fusion not VMware Player/Workstation (or use ESX/ESXi on Apple brand hardware) you violate Apple's SLA for this product. So any help can you provided for OS X in this use of the scenarios that it would violate the community VMware operating conditions to do.

Hi I noticed recently that now my restoration of the work system - properties - show two drives C: and D: WHY? I want to only show C:
He has never done this before and I don't want to show him D: at all, I have a HP and the D: drive is my restore disc, with D: listed means that he could get crushed and I don't want to appear in the recovery menu.
How can I delete the D: drive on the recovery menu but the C: DRIVE ON leave...
Thank you

With all due respect, you are incorrect. You simply did not notice before D drive. D drive is a logical drive. To the best of my knowledge there is no way to prevent it from the show. However, simply disable the system for D drive restore.

How to correctly get the percentage of CPU being used by the process
I try to get the % CPU used by process under windows with Qt/C++. First to get a list of running processes and after that, for each process, I try to get the CPU used, for most of the processes that the result seems valid (they correspond with the windows Task Manager), but with the process of AIDA64 (running a CPU in the background stress test), I got strange as 312% values what is the problem with my code c ++?
sigar_t *sigarproclist;
sigar_proc_list_t proclist;
sigar_open(&sigarproclist);
sigar_proc_list_get(sigarproclist, &proclist);
for (size_t i = 0; i < proclist.number; i++)
{sigar_proc_cpu_t cpu;
int status1 = sigar_proc_cpu_get(sigarproclist, proclist.data[i], &cpu);
if (status1 == SIGAR_OK)
{Sleep(50);
int status2 = sigar_proc_cpu_get(sigarproclist, proclist.data[i], &cpu);
if (status2 == SIGAR_OK)
{sigar_proc_state_t procstate;
sigar_proc_state_get(sigarproclist, proclist.data[i], &procstate);
qDebug() << procstate.name << cpu.percent * 100 << "%";
}
}
}
sigar_close(sigarproclist);
You may need to scale (divide) by the number of cores. This is the sigar code uses on windows to deliver the cpu process:
SIGAR_DECLARE(int) sigar_proc_time_get(sigar_t *sigar, sigar_pid_t pid, sigar_proc_time_t *proctime) { HANDLE proc = open_process(pid); FILETIME start_time, exit_time, system_time, user_time; int status = ERROR_SUCCESS; if (!proc) { return GetLastError(); } if (!GetProcessTimes(proc, &start_time, &exit_time, &system_time, &user_time)) { status = GetLastError(); } CloseHandle(proc); if (status != ERROR_SUCCESS) { return status; } if (start_time.dwHighDateTime) { proctime->start_time = sigar_FileTimeToTime(&start_time) / 1000; } else { proctime->start_time = 0; } proctime->user = FILETIME2MSEC(user_time); proctime->sys = FILETIME2MSEC(system_time); proctime->total = proctime->user + proctime->sys; return SIGAR_OK; }The doc of api windows indicates the time here is a sum on all threads and must therefore be reduced by the number of cores.
We had something like this in our use of links Java the 1.6.4 release of SIGAR. I'm curious to know if it works for you.

Problem with external monitor when used with the Satellite P100-434
I'm trying to use a Vizitron L - 151 monitor flat screen connected to the VGA port on the back of my Satellite P100 - 434 (PSPADE)
I find that the screens seem to periodically - feeding cycle windows resize themselves and then the screens settle down again. This happens with the laptop and the external monitor.
I've updated the latest available BIOS V4.20 (November 2, 2007) I use 7.15.11.6369 NVIDIA GeForce Go 7600 driver version. I'm under the edition of Vista Home Premium to standard build.
I even resorted to the use of the dvd system recovery to rebuild completely the laptop and the problem persists. In Device Manager I have generic Non - PnP monitor and below that I have a generic PnP monitor I tried and it is not possible to get specific drivers for the monitor Vizitron L-151. * NOTE * I saw dxdiag that the external display is identified the Non - PnP device
The display configuration that I'm trying to use is to have my laptop as the main screen with the external display on my left as an extension to the desktop. In display config my computer screen appears as number 2 with the additional display in the poster as a device 1
While typing this my screens have made this three times and the last time, this IE7 window installs itself to the external display in restored down to size.
If anyone has a glimpse of it, I would be very grateful. There are no problems when the external display is deleted.
_I can reproduce this problem on demand_ by uninstalling the monitor Non - PnP Device Manager.
Sorry, mate, but you ad confuses me a little and be hones I m not 100% sure what you take on
You have some problems with the resolution of the external display or what?I've found another thread on the setting of the external screen as main screen:
http://forums.computers.Toshiba-Europe.com/forums/message.jspa?MessageID=96263#96263According to this statement:
> In display config my computer screen appears as number 2 with the additional display in the poster as a device 1
It seems that the external monitor has been on the main screen and display books internal as external.I recommend you change this settings and to use books appear as 1 and the external display form 2.

Pavilion 15-p101nm: using all the RAM
I have 4 GB of RAM, 3.44 alone can be used by OS and etc, another 500 MB are RESERVED by GPU and CANNOT be used for other programs. When I check the properties and see "RAM installed," he said "4 GB (3.44 GB usable). Also when I run the Task Manager and look for physical use of Mem I see clearly that all usable memory is exactly 3.44 GB. So I want to somehow disable GPU on board and make all the usable memory, but do not know how... Actually I disabled it, but everything is still the same...
You can't just. On AMD a series it's an APU... the video tracks integrated into the processor itself and the switchable dedicated card is based on the embedded video. So you can't just use 100% of the system memory for Windows tasks. Some will be used by the video system.

the API system configuration error 1097 and freezes
I used successfully the API system configuration to detect and read information on a PXI chassis.
But now, when I try to initialize and collated all information using a simple VI, the system returns error 1097 and crashes before the end of the VI. Based on that the stop button does not work and I have to either soft or hard reboot the machine.
I have attached a screenshot of it in a frozen state and error, like a report of what is installed on my system.
The only thing I can think has changed since this last worked has been upgraded my MAX and other pilots from 5.5 to 14.0 and then the latest version as of today.
It is usually the generic error, which means that some external code access violated the integrity of the system and the memory is likely to have been corrupted in the process. Since it is a NI API system AND it seems to have worked before, I guess it's not a bad disigned call library node, but a form of bribery in external code library itself which implements the API of the System Configuration.
Reinstalling may solve the problem.

I have a valid Windows 7 Professional installation as well as a copy of VMWare Workstation running on Windows 7. I would like to install a VM Windows 7 that I can "break" without worrying about my host system. Can I use the same product key for the virtual machine that I currently use on the host system, or do I have to buy a different product key for the virtual machine?
Thank you!
No, you will need to purchase an additional license. The virtual machine is considered to be a separate computer.

VTEncoderXPCService the process using 100% CPU, slowing down of the MacBook Pro to a crawl
I'm running OS X 10.11.4 on my mid-2009, 2.26 GHz Core 2 Duo 13 - inch MacBook Pro, updated updated to 8 GB of RAM. For these last days, a process called 'VTEncoderXPCService' has been constantly running like crazy on my Mac, using about 150% CPU.

I need help [figure out what is the cause, as my Mac is basically unusable because of the drop in performance.
