i have home network with 1 PC, 1 netbook, 1 laptop and a network printer all connected together via a 2wire router cum ADSL modem. The PC which is running windows 7 professional 64bit, crashes with a BSOD randomly whenever my laptop is switched on and connected to the network. By randomly i mean sometimes it can run an online game for a couple of hours before it crashes, but sometimes it will just crash even when idle. All the crashing will only occur if my laptop (which is a 4 yr old fujitsu lifebook running win xp pro) is switched on. If my laptop is not on, the PC can run for as long as it like without crashing. Another thing to take note is that the crashes happen even after i just format and reinstall Windows 7. I updated all my device drivers to the latest versions already, and it still happens. However, i tried installing win xp home 32bit on the PC instead of the win 7 pro 64 bit, the problem is gone, the PC never crash. But win xp home 32 bit runs very slow on my PC, so i still want to try using win7 pro 64, but i got to fix the BSOD crashing problem. Ok, i was looking at other similar thread, so i disabled automatic restart after the BSOD, and this is the error msg i get in the BSOD: Tech information *** STOP: 0x0000007F (0x0000000000000008, 0x0000000080050031, 0x00000000000006F8, 0xFFFFF80002A94C91) Hope i can get some help on this!

Hi, This issue can be caused by the driver issue. I suggest we go to check the latest network card driver, update the NIC and the router. Please go to test this issue in Clean Boot and Safe Mode with Networking to determine the possible cause. If it works fine in Clean Boot, the root cause can be the third party software. If the issue reoccurs in Clean Boot, but works fine in Safe Mode, the cause can be the incompatible hardware drivers. You may narrow down the causes in Device Clean Boot. Device Clean Boot ================= 1. Click Start, type "devmgmt.msc" (without quotation marks) in the Search bar and press Enter. 2. Expand "Sound, video and game controllers". 3. Right click on your sound card and then click "Properties. 4. In the dropdown menu of Device Usage, please choose "Do not use this device (disable)" and click OK. 5. Please use the same method to disable other dubious hardware such as: internal modem, network card and CD-R drive. Please note some devices such as video adapter are not available to be disabled. Also, you can refer to the following KB article to test this issue: General causes of "STOP 0x0000007F" errors http://support.microsoft.com/kb/137539/en-us · If the issue persists, would you please upload more minidump files for further research?
