Hi,I have a weird problem with Windows 7.After upgrading my Windows Vista to Windows 7 Build 7000 64-bit on my desktop computer (which I have used for near one year with Windows XP Professional 32-bit and Windows Vista Ultimate 64-bit, both of them pretty stable), some times when doing my normal tasks, like exploring files on my computer and/or on network shares, my computer freezes completely. No mouse move, no response to keyboard, nothing. I have to reset it by hardware reset button.Before Windows boots, it says that there was an abnormal shutdown and asks to boot in normal mode or safe mode. But thats all. I cant find any reason why this is happening.There is never been a Blue Screen. Its always freezes. Sometimes, two or three times a day, and sometimes runs fine for a week.I'm sure that there is no hardware problem or incompatiblity in my system, so where can I look to find the problem?

How long do you wait for it to recover? I've had this happen when a video driver crashed. I waited a minute or so and Win7 rebooted the driver and kept the session alive without going to a blue screen. Pretty cool! So let it sit for a while, see if it recovers.

Ok, I'll try that. Thank you.

Ok, it won't recover even after one hour! :) So, what else I can try?

Well first off what software is running on the machine? AV, DVD burning, virtual CD rom drives,... anything? Or is this on a completely fresh install?mshadmehr said:...I'm sure that there is no hardware problem or incompatiblity in my system, so where can I look to find the problem?There must be something causing it, so there must be an incompatible software package or driver somewhere.

I think I found the problem. I have VMware Workstation 6.5.0 Build 118166 installed on my system, and after disabling its NIC/LAN drivers and removing VMware Bridge Service from my physical network connection (Realtek RTL8168B/8111B Family PCI-E Gigabit Ethernet NIC NDIS 6.0) my computer seems to work normal, at least for past 12 hours! :)

Upgrading to VMware Workstation 6.5.1 Build 126130 doen't seem to help. Adding VMware Bridge Service to network connection still results in a frozen system...
