Question about Acer Aspire 3680 Laptop
When i log in a window appears with " error 0xc0000005" and i can't access the desktop. Can you help?
Hi there, The error 0xC0000005 is generated by an illegal "memory access
violation". This can be caused by anything from faulty RAM, an
incorrect/corrupt device driver, poorly written/updated software and
more commonly under Windows XP Service pack 2, malware/adware
i would suggest that the ram in your computer has possibly broken down over a period, may i recommend obtaining some new ram, if you go to www.crucial.com they can provide you with information that tells you which ram you have in your PC.

The error 0xC0000005 is generated by an illegal "memory access violation". This can be caused by anything from faulty RAM, an incorrect/corrupt device driver, poorly written/updated software and more commonly under Windows XP Service pack 2, malware/adware installations.
Usually you get this error message when performing a specific task, and if that happens you need to check the corresponding 3rd party's website/support department to see if they are aware of the problem
..a while back symantec Antivirus caused the 0xC0000005 error with an additional message about a file called SAVRT.SYS . A simple software update to the Symantec Antivirus cured the problem.
So what can you do...? well below are a couple of suggestions:
0xC0000005 - Resolution Suggestion One:
In many cases this error has been generated by faulty RAM memory. So if you have just upgraded your computer with some new memory and you started getting this error then I would remove them and see if the error goes away. If it does then send the memory back and get a refund!
0xC0000005 - Resolution Suggestion Two:
In Windows XP Service Pack 2 Microsoft introduced Data execution prevention (DEP), a set of hardware and software technologies that perform additional checks on memory to help protect against malicious code exploits. In Windows XP SP2, DEP is enforced by both hardware and software.
Some software/application behaviors are incompatible with DEP - data execution prevention. Applications which perform dynamic code generation
(such as Just-In-Time code generation) and that do not explicitly mark generated code with Execute permission might have compatibility issues with data execution prevention. Applications which are not built with Safe SEH must have their exception handlers located in executable memory regions.
Applications that attempt to violate DEP will receive an exception with status code STATUS_ACCESS_VIOLATION (0xC0000005).
If an application requires executable memory, it must explicitly set this attribute on the appropriate memory by specifying PAGE_EXECUTE, PAGE_EXECUTE_READ, PAGE_EXECUTE_READWRITE or PAGE_EXECUTE_WRITECOPY in the memory protection argument of the Virtual* memory allocation functions.
If you are having issues with 0xC0000005 errors in DEP and a particular piece of software is causing the offense, contact the vendor for a resolution...
Note: It is possible to "Turn Off" DEP in the boot.ini file but this really would be a last step!
This option is only available on 32-bit versions of Windows when running on processors supporting no-execute protection. It enables no-execute protection (also known as Data Execution Protection - DEP), which results in the Memory Manager marking pages containing data as no-execute so that they cannot be executed as code. This can be useful for preventing malicious code from exploiting buffer overflow bugs with unexpected program input in order to execute arbitrary code. No-execute protection is always enabled on 64-bit versions of Windows on processors that support no-execute protection.
There are several options you can specify with this switch:
/NOEXECUTE=OPTIN Enables DEP for core system images and those specified in the DEP configuration dialog.
/NOEXECUTE=OPTOUT Enables DEP for all images except those specified in the DEP configuration dialog.
/NOEXECUTE=ALWAYSON Enables DEP on all images.
/NOEXECUTE=ALWAYSOFF Disables DEP. (This setting doesn't provide any DEP coverage for any part of the system, regardless of hardware DEP support. The processor doesn't run in Physical Address Extension (PAE) mode unless the /PAE option is present in the boot.ini file.)
0xC0000005 - Resolution Suggestion Three:
I have also seen this error in the gaming community when folks have updated drivers for their graphics card. If this happens just roll back your drivers.
0xC0000005 - Resolution Suggestion Four:
Microsoft Internet Explorer 6.0 stops responding when you try to open an HTML document or a Web page. Additionally, you receive the following error message:
Access Violation (0xC0000005 exception)
This problem may occur when you use Internet Explorer 6.0 to open an HTML document or a Web page that contains SPAN tags. If a SPAN tag is not closed correctly by using the </SPAN> tag, an access violation may occur.
WHY are you using IE6 still??? Upgrade to IE 7 today!
...and that should have now resolved the 0xC0000005 error for you!

The 633 error is a connection problem that appears every time you try to use the modem on your computer.
It states "modem is already in use" and prevents you from accessing the Internet.
This problem mostly appears when a device with incompatible drivers has conflicts with the modem driver on your computer system.
The major software that causes this error is the Palm Pilot Software.
With some simple troubleshooting steps, resolve this modem communication error.
Shut down all currently running applications and restart your computer.
Press "F8" repeatedly before Windows begins to open the Windows Advanced Options Menu.
Scroll down and select "Safe Mode." Press "Enter" to log into Windows Safe Mode.
Safe Mode is used for troubleshooting and repairing system components.
Click the Windows "Start" button and select the "Control Panel."
Double-click "Add or Remove Programs" to open the programs window.
Click "Program and Features" (Windows Vista users) and select "Uninstall a Program" to open the programs window.
Click the incompatible software (e.g., Palm Desktop and Synchronization Software) and select "Change/Remove."
Click "Yes" to confirm and uninstall the program from your computer.
Restart your computer normally to complete the process.
Hope this helps
