OS 64bit Ultimate my network card randomly disconnects as soon as I do a repair it works but sometimes only for seconds and other times it works for some hrs. Have tried to install a new card but makes no difference Any Ideas.

Hi caretaker, The issue can be caused by the following factors: 1. The network card is incompatible with Windows Vista. 2. The current network card driver is incompatible with Windows Vista. 3. Third-party program conflicts. Currently, I suggest performing a Clean Boot to troubleshoot the issue. Clean Boot ======== 1. Click Start, type "MSCONFIG" (without the quotations) in the Search Bar and Press "Enter" to start the System Configuration Utility. Note: Please click Continue if the "User Account Control" window pops up. 2. Click the "Services" tab, check the "Hide All Microsoft Services" box and click "Disable All" (if it is not gray). 3. Click the "Startup" tab, click "Disable All" and click "OK". 4. Restart the computer and test the issue. Note: Clean Boot is a troubleshooting step. If some programs have been disabled, we can re-enable them later. If you see the System Configuration Utility, check the box of "Don't show this message" and then click "OK". Please test this issue in the Clean Boot environment., if the issue disappears, we can use a 50/50 approach to quickly narrow down which entry is causing the issue. If the issue persists, please let me know the brand and model of your network card. Hope it helps. Best regards, Tim Quan Microsoft Online Community Support
