Question about Computers & Internet
I just paid ITOK $75.00 to give my computer a complete tune-up. So, this shouldn't be happening!
Check to see if there are any keys stuck/depressed. If so, use a paperclip and fit it underneath the key and gently pry the end that is stuck. Make sure the laptop is off before attempting this. Observe where the boot process ends and starts over. In most cases, this will give an indication where the problem occurs. If the laptop reboots early on in the process, for example when it is detecting the hard drive, chances are good it is a hardware issue. If the reboot occurs further along in the process, like when it is loading operating system files, there may be an issue with operating system software. Test all power and data leads that attach to your hard drive SATA the leads from your (motherboard to your hard drive) make sure they have a secure dust free connections and are not faulty Make sure all leads that are attached to your drives dvd\cd have secure connections and are not faulty. even something as small as faulty fan lead can cause you problems computers need all of the data and power to travel through every working device and to have an end for a computer to be able work properly. Motherboard and a hard drive any leads between them will fail before your motherboard or your hard drive check all power and data leads make sure they are securely seated even the cd/dvd drives need to have current go through make sure these devices are working Check your computer ram modules for secure dust free seating you might even remove the ram modules to check for dirt on modules and in the module socket and cmos battery make sure it has charge and they are dust free and securely seated some motherboards cmos batteries are soldered in If your computer runs long enough scroll to bottom toolbar (bottom of screen) right click select task manager applications you will see whats running if you see anything you dont need running select end now and you might uninstall that specific program if you or computer does not require it to run and some unnecessary programs that could be running your computer over its limits causing memory dumps also under processes see what is ticking over in the background you might have a virus again if you see something you dont need to be and users you will see who is using your computer
You might need to add more computer ram if you're not sure if a module is right for your system use the Crucial Memory Advisor tool for a list of guaranteed compatible modules. first you will need to select the manufacturer from a drop down list then select your product line from a drop down list then select the model then click find it will take you directly to compatible ram also you will have an option to scan your system You should always ask for a guarantee on the compatibility of the ram before making any purchase Might be getting hot check you CPU make sure its securely seated and has thermal grease http://www.hardwaresecrets.com/article/Thermal-Compound-Roundup-February-2012/1490 Capacitors look like small metallic canisters and they are found in many different computer components including computer monitors, computer motherboards, video cards, power supplies and a variety of other consumer products. A bad capacitor can cause a variety of computer problems, but if you can identify the faulty capacitor you may be able to replace it and save your computer.
Capacitors, sometimes also called condensers, are used to store energy in an electric field. In the context of computing, capacitors are used to block the direct current being circulated around the motherboard. A typical capacitor should last up to 15 years, but some computer manufacturers use substandard capacitors resulting in shorter lifetimes. Computer Problems b> When a capacitor has gone bad on a computer you may experience a large range of problems. The computer may have trouble booting up, or it may shut down without notice after running for only a short period of time. The most common problems associated with faulty capacitors are that they cause unexpected computer crashes and general reliability issues ranging from read/write issues to distorted screen images. b> Identifying a Bad Capacitor b> To identify a bad capacitor you will need to open your computer case and locate the capacitors on your motherboard. A bad capacitor may exhibit swelling at the top or the base of the capacitor or it may sit at an awkward angle with the motherboard, so compare the various capacitors in your computer in terms of and placement. Additionally, a bad capacitor may have a funny smell or it may have a brownish residue leaking from the top or the base. b> Prevention b> Manufacturers claim that capacitors may go bad because a computer is not receiving enough power from a power supply, because of an overclocked processor or because a computer is operating in an environment with too much heat or humidity. However, some capacitors prematurely fail due to faulty work on the part of the manufacturer. If you have a bad capacitor be sure to do research as to the lifespan of other products made by your manufacturer.

SOURCE: after automatic updates and a restart, diagonstic lights A & C were yellow and D & B green, nothing comes up on screen, this happen before after an update but i got it to start after several a
If all diagnostic lights are on, then that means that it has something with the software of your computer. The update has affected some of the programs inside your computer thus it's booting up fine.
I suggest that you access safe mode and do a system restore from there. If you don't know how to access safe mode, then follow these:
1. Turn off your computer.
2. turn it on and keep tapping F8 until you see the options. You should see safe mode.
3. Use the arrow keys to select safe mode, then press enter.
4. Your computer should boot up to safe mode.
5. Access the system restore. You can find it in accessories, system tools, system restore. or you can search.
6. restore your computer to the known good date where your computer was still working fine.
7. After completing the on screen procedures, let your computer restart by itself (it may take minutes or more). It will restart and it should boot to the normal windows.
I hope this helps.
