Very display card using memory and if the memory is loss and need to find it but can't find it, so the system is halted. this also same like RAM that every PC have where it cannot function the computer also halted.
Normally happening because of dust near the plug in inside the PCI slot also same like RAM. We go to the service centre then ask them to clean all the hardware component inside laptop or desktop. After that makesure they also reinstall the driver again;
If It happening again; advice change the graphic Card because it cannot function very well or not function at all.
Others could be from the Window Defender or some people dont relliaze that they got Window defender software. Where function of window defender is good. But something Digital sinagnature from Microsoft cannot support this version and window defender always focus on software that don't have permitted for joining the OS of Microsoft whether XP sp2, Vista or others OS from Microsoft. It could be the reason.
Logical that I found it because I check one PC that bought in 2005, when today got software from microsoft Window defender; it scan all the software and try to get digital signature for integrate with Microsoft OS for making good performance; but what happening This error occur ati2dvag has stop working properlly.
or any other driver installed in your laptop is getting blocked while you r using some files as this is making it freeze.so just reinstall your operating sytem after deleting the curent operating system in your pc.

This tends to be the problem of overheating .

Check whether there is proper ventilation for fan.

Heatsink can be the problem .

How to replace the keybord on an advent 9517 laptop


Advent laptops are manufactured by DSG International, which owns the names to other name-brand computers such as Acer and Hewlett-Packard.
The Advent laptop keyboard has integrated mouse touch-pad functions that allow you to move the mouse around the screen with your fingers.
Function keys at the top of the board contain alternate ways to exit and enter software applications.

Function Keys
The Advent laptop keyboards function keys are "hot keys" that act as shortcuts to applications and functions on the computer. The function keys sometimes don't work and won't carry out the function assigned to the key. This problem is considered a hardware malfunction, and the solution is to replace the keyboard or use a universal serial bus (USB) keyboard for the laptop. b> Malfunctioning Keys b> Advent keyboards are made of thin plastic. Striking the keys too hard will cause the keys to break or stick awkwardly in the housing unit that supports the keyboard. When these keys get stuck in the housing unit, a pin tool can easily set the keys back on track. If there are too many keys that get stuck or broken, you can purchase a replacement Advent keyboard and have it installed. b> Mouse Problems b> The mouse is located at the bottom of the Advent keyboard but is connected to the keyboard data strip that sends information through the keyboard unit to move the mouse on the screen. If the mouse malfunctions, check the connector under the keyboard to see if it is loose. A loose connector can cause the mouse or other keys not to function on the laptop. b> Electrical Shortage b> An electrical shortage can cause an Advent keyboard not to work properly. A shortage is when the main board of the laptop is not getting the voltage needed to efficiently operate the computer. When this happens, certain devices underperform or become inoperable. Check to see if your power supply is extremely hot or if your system heats up around the keyboard. If so, replace the electrical adapter. b> Wire Damage From Keystrokes b> The wire that is responsible for the liquid crystal display (LCD) on the Advent laptop extends from under the middle of the keyboard to the LCD display unit. This wire is unprotected and can be damaged from striking the keys over the wire. When this happens, the display will not show the correct colors or the screen will go black. To eliminate this problem, purchase a keyboard cover that fits the keys to relieve the pressure between the keyboard and video cable. b> Keyboard Drivers b> Problems have been reported with upgrades from Windows Vista to Windows 7. Windows 7 will not recognize the system drivers that operate the Advent keyboard. To get the keyboard to work, you must load the old drivers in Windows 7 Safe mode, which is used anytime there is a hardware or software discrepancy. Advent keyboard drivers can be loaded from the original restore CD, which is included with the system at the time of purchase.

My advent laptop turned off suddenly and now it turns on but its a blank screen


Check it is not overheating, common issues with Advents are the death of the Graphics chip as this is cooled poorly by the fan. You can usually remove the large inspection hatch under the laptop and check that the fan is not clogged with debris and dust. Try cleaning it and see if that helps.

Also try to plug the laptop into an external monitor, if you get a picture on there, the graphics chip is working ok and the problem lies in the screen inverter or backlight. At this point, unless you are technically confident, it is best to take the laptop to a repair shop to have the screen and inverter tested

I have a advent notebook which wont turn on and sais that an error accured whilst trying to load configuration settings?????


You may have to contact Advent to try to get a recovery CD - however, there are a few things to try.

1) Try booting the system into SafeMode. To do this, as soon as you turn the system on, tap the F8 key und you will get to the Startup Option screen. Use the arrow keys to highlight SafeMode and press 'Enter'. This will either work or it won't and it may freeze with the error. IMPORTANT: Write down the error - we may be able to find a workaround with that information.

2) If you cannot get to SafeMode, reboot the system and follow the same process to get to the Stoartup Option screen. This time select SafeMode with msdos prompt. If you can get there, we can possibly run a System Restore in DOS and turn your system back to before you had the issue.

Let me know how you make out and we'll move on to the next step.

Good luck,

TIH

when was the last time your computer worked fine? run system restore and choose a restore point prior to when the issue started. if no restore point is available, open run and enter 'msconfig', go to startup and disable unecessary startup programs. also open the prefetch folder and delete its contents. then restart your system. if it's still slow, i suggest you backup your files and reinstall windows. make sure that you operate the laptop on a flat surface to avoid any ventilation blockage. hope it'll help. good day. =)'

Synaptics touchpad not working properly


Hmm give this method a try. Turn off computer remove AC power adapter. Remove the battery and press the power button for 30 seconds continuously. This removes the static from the system. This process is called as Power drain. This works in most of the cases. Good Luck !!!

Dropped laptop


Press and hold the <Fn> key while powering the system on. This will run the Dell Diagnostics. Another more intense diagnostic program is located on a Dell CD that you should have received with your laptop. Look for one that has “Diagnostics and utilities” listed under the “Contents”. You will have to boot from that CD disk. To do this, power on your laptop and tap the <F12> key to bring you to the “One time boot menu”. Insert the CD and then select CD/DVD drive and hit <Enter> key. Select the “Run the 32 Bit Dell Diagnostics”.

One of the best sources for these types of things is online at a site called newegg.com. You can search based on the Manufacturer and model number of your Laptop. If that fails you try the Manufacturers website, they will sometimes list where replacements can be purchased or well on themselves.
