    My brother bought window 7 and I use XP. What do we have to do for me to control his computer from my XP, so I can help or fix the errors.

    all you need is an application called "Remote Desktop Connection", it comes pre-installed in windows 7, if you have windows XP home, you can't get the remote desktop, but if you upgrade to XP Professional you can.

  • Need help to diagnose the regular system analysis on iMac - processors maxed out

    I need help to identify the cause of a problem that occurs at least 2 - 3 times per day using my iMac (27-inch, mid 2010) running 10.11.5.

    I will use my iMac and then all at once things will start to really trolling. To the point of being completely unusable. Even if I'm able to move my cursor, then click to drag the windows around the screen nothing does really.

    I have iStat menus running so that can see graphics in my menu bar that all 4 cores are completely overfished. Occasionally, I was fast enough to launch the activity monitor to try to see what applications / services are responsible for, the use of % CPU column is completely empty of values, so I can't identify the culprits in a reliable way. I try to keep that column sorted by % CPU use in the hope that he could reveal something and normally it's the kernel_task who is up there.

    I use a Wacom Bamboo dated Tablet (MTE - 450 has) instead of a mouse, and at one point, I was convinced the pilot of PenTabletDrive it is based on was to blame. I contacted Wacom on this subject, and although there is no known issues they pointed out that although the latest drivers will allow me to use the tablet that they no longer support older devices. I was wondering if there was a problem of communication between the device and a driver that is no longer supported. I installed the latest driver supported for my tablet, but the problems persist.

    It may be interesting to note that, when my computer is in this semi-frozen state, I am able to launch the window enough force and quit all open applications leaving me with only the Finder. I guess that means that there are none of my apps running and it is probably one of the services. If I restart the Finder system grinds to a completely enclosed holt.

    I hope someone can let me know what I can find in the Console or elsewhere to help me finally zero in on what is to blame. I can share a log if that helps.

    Thank you in advance!

  • Need help to remove the zeros on the right

    Hello.

    I need help to replace the zeros in the string.

    I have a string which is the output of the network packet. There are a few trailing zeros in the package.

    I don't see them in normal mode, but the size of the string tells me that it's bigger then it looks like.

    When I pass in hexadecimal mode, you can see zeros.

    I tried to use the find/replace function allows you to search for 0 and replace it with an empty string constant. But, for some reason any, that he took no zeros.

    I need to stop the string that follows * 69.

    Show your code.  You won't find and replace with all zeroes.  These 00 in hex mode they are null characters.  (not printable byte with a value of zero).  You need search and replace on that character.  (replace string should look like 00, when it is set to display the hexadecimal code.

  • I need help to Flash the bios. I have an Aspire 5810TZ. I start and it just says: "acer".

    I need help to Flash the bios. I have an Aspire 5810TZ. I start and he just says "acer" and goes no further. I went to the download page for BIOS on us.acer.com and it has a zip file with 5 files:
    JM4151135.exe
    IN FLORIDA...
    GPC_V135.bin
    Readme.txt
    FLASH. BAT
    What should I do? I tried to copy the files on a USB key and turn on/off with Fn + ESC key. After the release the power button and pressed Fn - Esc another screen appears after 30 seconds. I gave up and gave her 30 minutes but it does nothing. I read another person that should be flashing power button online. I have to rename one of the files. Help, please!

    Aspire 5810TZ menu of frozen startup.

    I finally understand it.

    I couldn't start a back b/c drive, it me did not start anything.

    I followed this chain of logic:

    -Downloaded the bios (2.35 is the one that worked for me)
    -Find the exe file in the winflash file.
    -Extract the files in archive exe using the 7-Zip program
    -Find the .fd file and rename it to JM41X64. FD (I read in a forum was unique in my laptop)
    -Copied JM41X64. FD and FLASH it is. EXE on a USB
    -A the battery and the hard drive out.
    -With its trendy diet I supported Fn + Esc and that you press the power button once while ensuring that the Fn + Esc has been always held down.
    -J' waited 6 seconds and release the Fn + Esc and seen the flashing flash player
    -After about 10 minutes, restarted the machine and the bios as like new.

    Later, I found that there was a hard drive problem.

    I want you guys should help more. All I needed was the name of the JM41X64 file. FD and you don't know how many hours I put into trying to find how simpy bios flash. It is not that difficult for someone with a b.s. in computer science to learn how. Couldn't we a m.s. back b/c the bios drive was messed up. F12 didn't work.
