• surcurity essentials does not start, and the windows firewall does not illuminate

  Hello

  I have a problem, he seems to have had a virus on my pc. Essentials of security does not illuminate and the windows firewall will not also turn on, I tried to use the tool to "fix" windows and it doesn't solve the problem.

  the original virus seemed to rename its self as a program existing and renamed the oringinal by a space in the name, for example "adobearm.exe" became "adobearm .exe" there is a space before the dot.

  The virus called his free adobearm.exe icon because it is a yellow / orange with a letter H, at the Center

  different file name her seemed to be part of the virus included "ag7yl5x8.exe".

  If you tried to close them in the task manager that they just either came back or a different file name would appear in the list.

  Remove the RAM modules with good modules tested and check the functionality of the laptop.
  In the case of RAM isn t the troublemaker, the motherboard could be affected.

  Hello

  It looks like your Qosmio F750-03W PQF75C 03W001 is a Canadian model of Toshiba that I found it here:
  http://support.Toshiba.ca/support/ISG/Center/en/index.asp?S1=notebook&S2=Qosmio&S3=F750&S4=PQF75C-03W001

  First you need to update the BIOS with the latest version (at this time, it seems that BIOS 2.0 is the most recent).
  Also update the
  nVidia Display Driver version 8.17.12.9039

  If stereo 3D effects are not well use X-tune to calibrate it.

  You said that your face recognition does not work correctly so uninstall this software. This also with the software/driver for webcam. Once these two tools has been uninstalled, clean the registry with CCleaner and install these two tools using the most recent version.
  Restart and start X-Tune to calibrate the 3D effects.

• Satellite U300-13U does not start and the recovery disc fails to too much work

  Hi all

  I have the above computer (or should I say my wife) & it is nothing that a good pain since the first day we got it.
  I have had it about 2 years & had to reformat the HD at least 6-8 times using the product recovery disc as laptop starts.
  The laptop runs Vista.

  In any case, problem I have now is that new laptop does not start, but for some reason any product recovery disc also does not work...
  What I can do...

  I have read on various forums that it might work if I reformat the HD first using some s/w on a bootable CD but how / what S/W can I use...?
  The laptop has a SATA HD 160 GB installed. How can I check that it all works.
  I don't know if the current problem is S/W or related material...

  Toshiba has a utility that I can use...?

  Thanks a lot for all the help...

  John

  Hello

  What happened exactly?
  Do you receive error messages by using the recovery disk?

  Check if the HARD drive is OK! You can check in the BIOS.
  If the HARD drive is listed in the BIOS then the HARD drive and HARD drive found BIOS is not dead.

  Usually, you might start Notepad with the help of a Live disc for example Bart PE
  It s a bootable windows CD/DVD live

  http://www.nu2.nu/pebuilder/

  This can allows you to format the HARD disk, and then use the recovery disc!

• How can I fix computer that does not start after the fan turns phase?

  I have a Compaq Presario SR5510F PC, Windows Vista Home Premium, AMD Athlon x 2. Lately, my computer is even worse at the start. When my computer starts, the fan should run for a few seconds, then it should stop and lead at the start with Compaq logo screen. But lately, the startup was completely terrible for my computer. Today, most of the time when I press the button in the box of the computer, the fan turns on and it continues to turn, and nothing comes on the screen. It isn't that rarely when the fan stops running, but then the monitor displays always upwards in white and VERY rarely when the startup screen appears, then it freezes on this screen. At this rate, my computer is totally useless when it does nothing but run his fan. This means that I can not go to boot options at all and go to the "last good configuration". What can I do to fix the computer when I can't have anything with her while she is empty?

  It sounds like a hardware problem, not a software problem.  If the computer rarely gets past the BIOS (material audit) stage of the startup sequence, then Windows is is not yet involved in the boot process again.  Request assistance from someone trained in the skills of troubleshooting hardware since this can become very expensive very quickly.

  2. restart your computer using the power button on the computer.

  If your computer is not configured to start from a CD or a DVD, see the documentation provided with your computer.

  4. choose your language settings, and then click Next.

  Tom,

  80070424 means that a required service is not present or running.

  First of all, make sure that all your personal data and program installation files are saved in one location other than your computer, as soon as POSSIBLE.

  What is the installed security/antivirus suite. is it's subscription and current definitions; whatever it has detected the last time that the system has been analyzed with it?

  Please run this tool Kaspersky to see if it is "hid" software malware present - How to remove malware belonging to the family Rootkit.Win32.TDSS

• Satellite L40 - does not start and the screen is completely blank

  Hey guys,.

  A good friend of mine has a laptop Toshiba Satellite L40, who died recently, and she has not been able to find the warranty documents yet, so I wanted to ask if maybe you could help.

  Basically, what's happened is that one day she was using the computer and not have noticed that it was not plugged in to charge, and before completely lost all power, the computer went into automatic hibernation mode.
  It plugged into the charger, the lights indicated that he was in charge. A few hours later she was trying to turn on, but nothing. the computer itself gives off a sound very low, as if turned on, but the screen is completely blank. She said that it's almost like she couldn't make the thing out of hibernation mode. He continues to give sound and some indicators remain lit until the battery is running out of charge.
  She has Windows XP is installed on the computer.

  Perhaps someone could help as to what is happening here? 1 million thanks!

  ME

  Hello

  Weird, but have you tried to remove the adaptor AC/DC and battery? Wait one hour and then reconnect the adapter AC/DC and battery. Maybe the laptop restarts.

  If this isn't the case, I think that you need assistance from an authorized service provider. It seems to be a hardware problem and the laptop should be checked by a technician from Notepad to determine the cause of this problem.
  On the Toshiba site, you can search the nearest ASP:
