Help My Computer Won't Log On To My Profile

  This is a common problem with viruses today. You were on your computer the night before and everything was okay. You start your computer the next day and when you try to log on to your profile it kicks you back out. The user profile failed to log on is the typical message that you may receive. So what are you going to do at this point. On almost every computer that this is happening I have found it to be a virus. There is also that slim chance that a power interruption or brownout may have occurred.  This can cause corruption to the registry, damage to the motherboard, other components in the system or corruption to the software. Well you have a few different choices. The first obvious thing to determine is did you in fact have a power failure. If you did I would inspect your motherboard for any signs of damage such as popped leaking capacitors.

  The next step is could it be a virus, malware or a piece of unwanted software that got into the system. First try booting to the safe mode with networking. I would also download some virus cleaning tools off the internet. Create a folder for example on a USB Flash Drive and copy all these virus cleaning programs to it.  I would suggest combofix ( unless it is windows 8.1), Free Malwarebytes, Spybot 2.4 and tdsskiller.exe from kaspersky's website. Copy them over to the desktop and run then in this order Tdsskiller, Combofix, Free Malwarebytes( make sure to update it) and Spybot 2.4 Portable. Reboot the computer when instructed by the program. Reboot especially after running Combofix because it run Rkill to stop various items in the system. There are other virus programs that you can download and run such as Super AntiSpyware Portable and Eset Online Scanner.
  If you can not enter the safe mode either, then try going to a command prompt after pressing the F8 key on your keyboard. You will need to know a little about dos to select the folder where you save these programs. You can run each program rebooting when necessary. If the computer does boot properly update your virus software and run a full scan on the system. This may or may not solve the problem with the log on. If you can get into a different administrator account you could create another profile and move your data to it, then delete the old profile. Just remember to run the Virus Cleaning Programs on all profiles to remove any infections.
  If you can not get into the system by any of the above virus cleaning methods, then there is a registry fix for this problem. This probably the best link to go to from Microsoft to repair the users log on profile http://support.microsoft.com/kb/947215 . Here is another link to a website with instructions on how to repair the log on profile http://www.pcadvisor.co.uk/how-to/windows/3495216/how-fix-corrupt-user-profile-in-windows-7/ . Just copy and paste the web address in to your address bar and press enter. The second website is the same information as the first, but will have ads. Follow all the instructions that they give you. Reboot the computer and see if you can now log on. If you can log on properly be sure to run all the virus cleaning programs. Make sure that you have a good up to date Virus Cleaning Program  installed on you computer. I have seen too many times where the virus program has expired.
  I hope this information is helpful. Also if you are not comfortable with doing this check your local computer store for whatever virus cleaning they may provide. Just check out any reviews on the computer store for any bad experiences. It does happen from time to time.

Are Solid State Hard Drives Going To Come Down In Price

  I have been doing some searching on the internet and it looks like the prices of  Solid State Hard Drives  are slowly coming down. It would be nice to make them more affordable for the general public. In the beginning when we first saw the solid state hard drive they were extremely expensive. I myself have noticed that they did drop a little where I work. At this point and time if you can afford a solid state hard drive they will make somewhat of an improvement in speed. They function very well as the boot drive in any system. I would just recommend a good power supply running 650 watts or more. Especially if you are running more than one hard drive or two optical drives.



  • Highest-quality components and engineering from the #1 memory manufacturer
  • Worry-free data security with AES 256-bit full-disk encryption
  • No moving parts means no hard drive spin ups, no noise and superior data protection
  • An innovative lightweight design that allows you to work smarter and play longer.
  • Sequential Read Speed 540 MB / Sequential Write Speed 520 MB / Random Read Speed 97K / Random Write Speed 66K
  In 2011 the average cost of a solid state hard drive was $2.42 per Giga Byte of hard drive space. It would have cost about $250.00 for a 100GB solid state hard rive. At Newegg.com you can find a 256GB Samsung Solid State Hard Drive for about $169.00, which is not too bad of a price. On the higher end you will find 800GB Solid State Hard Drives costing in the thousands of dollars. This maybe appropriate for computer in a business environment, but not for the general computer user. My advise is to stay with a sata hard drive due to cost verses the amount of hard drive space.
  Right now a 1TB Sata 3.5 inch at Newegg will cost about $70 and a 2TB Sata Hard Drive runs around $90 Dollars. So if you are looking for a solid state hard drive I would check out Newegg. I have used them many times and never had a problem. Outside of Newegg I would search Amazon and Ebay. I have also found some very good prices there as well. So what is the best brand of Solid State Hard Drive  on the market today. From looking at reviews it looks like Samsung is one of the best brands available. The other popular brands that I have seen are Plextor,  Vector and Neutron.
  So whatever your choice is I would check as many reviews as you can find on the internet for a particular solid state hard drive. Check out the good or bad reviews on the reseller or dealer you may be thinking of purchasing the hard drive from. A very good place to check out a reseller on the internet is resellerratings.com where you may be able to locate helpful information.

My Desktop Computer Or Laptop Computer Just Shuts Off.

  If your Desktop Computer or Laptop Computer just shuts off by itself only after it has been on for a few minutes or seconds check your fans. I have seen numerous times where the CPU fan and heatsink are full of dust and debris. If it is a desktop, first disconnect any power to the computer. Open the side cover and check for dust especially in the CPU fan and heat sink. The system is designed to shut down if the microprocessor overheats. This protects the motherboard from damage. The best solution is to use an air compressor to blow out the dust. I would do this outside and wear a dust mask. When blowing out the fans I would hold your finger on a fan blade so it does not spin. The compressor will make the fan spin faster that it should and can damage the fan. Also do not stick your finger in the fan while it is spinning. I have seen people get cut by this. If it still has the same problem test the power supply and check for bad voltages. Also check all power connections. The next step is to replace the power supply.
  Other components to check are memory for poor connections. Try re-seating the memory in the slots. Just wear an esd wrist strap before handling any component. You can also try removing the power from one component at a time to determine if the computer all of the sudden powers on. Replace the bad component. Another popular item to check is the latches on the microprocessor fan and heat sink assembly. I have seen the plastic become brittle and break. This results in the microprocessor overheating.
  If you are working on a laptop then you have some different paths to take. The first thing to check again is the cpu fan. Some laptops actually have more than one fan. I have found many times that the dust balls up in the fan blades and stops the fan from spinning. In this situation the first thing to do is determine if there is a removable panel on the bottom of the case. If there is remove it and then remove any dust from the fan. You can use an air compressor ,but be sure to hold the fan blade so it does not spin too fast. If there isn't any cover then I would remove the keyboard carefully. Sometimes there is a small opening at the fan. You can then blow the air through the bottom of the air vent and the usually blows out of the fan. You may have to use small needle nose pliers to remove dust clumps.
  If this is not the problem try removing all components one at a time. If you remove the last one and still has the same problem, then I would suspect a defective motherboard. Always make sure you are getting something on the lcd display. If nothing check the lcd ribbon cable and try an external monitor. I do not suggest replacing a motherboard unless you are capable of doing it yourself. I have seen too many cases where the part and labor exceeds the cost of the laptop. Plus you do not know how long a refurbished motherboard will last.

Watch Out For The Ransomware Viruses Going Around

 I was just reading about a ransomware virus that basically takes control of your computer, activates your webcam and actually takes a picture. The screen comes up with a realistic FBI warning that you have been watching child pornography. They then want you to give them money somewhere around $200 dollars. Obviously the FBI would never conduct an investigation in this way. The wanting of money is definitely a dead giveaway. So do not panic as a poor fellow in Florida did.
 You have two choices on what course of action you take. The first is if you have access to another computer you could download the free hirens 15.1 and 15.2 iso files and burn them to cdr disks. The download tdsskiller.exe, combofix, free malwarebytes, spybot (current portable version), Eset online scanner portable version and super anti spyware portable, clamwin portable and a-squared. Download these to a usb flash drive that is at least 4gb. First on the infected computer try to boot to the safe mode with networking by pressing the F8 key during the post test. If you can get to the safe mode, copy the programs from the flash drive to the desktop. I usually keep them in a folder called virus cleaners. Run them in this order rebooting if necessary. Tdsskiller.exe, Combofix.exe, Malwarebytes, SuperAnti Spyware, Eset, Clamwin and A-squared. Most of these can be downloaded from bleeping.com . Clamwin and Super Anti Spyware Portable may have to come from their own websites.
  If you can not enter the safe mode, boot off of the hirens 15.1 disk, choose mini windows environment and copy your virus cleaning programs to a folder on the root drive. I should note that super anti spyware will have to be started first from the hirens disk. It is in the programs list under virus cleaning or something to that effect. If you try to run your downloaded version first the computer will bluescreen and you will have to start over. When all virus cleaning programs have been run you can try rebooting to the normal mode. Also note that Combofix does not run yet in windows 8.1, but runs in windows 8.  
  Another option is to connect a good known hard drive, install a fresh load of windows. You do not have to activate the software due to only using it to run the cleaning software. Connect your infected drive as a second drive in the system. Run all virus cleaning programs rebooting when necessary. Disconnect the fresh install drive and reconnect your original and try booting up the system. If it still will not run, then the only alternative is to save data, wipe out the hard drive by repartitioning and reformatting. Reinstall the windows operating system and activate windows. Reinstall all software and virus software. Copy all your saved data back to the system. All programs will have to be reinstalled.
  If you are not comfortable with doing this your self then I would suggest taking it to a professional computer service shop in your local area. Check out any reviews before taking it to any computer repair shop, so you save yourself any headaches. Avoid any place that says it has to be wiped out before they even try to clean the viruses. There are some places that will do that so they get it out as fast as possible. That is not customer satisfaction. Also watch out for any service shop that quotes one price and then wants to charge more.
 Thank You for reading, I hope this helps.
