3. I used the program “WhoCrashed” to find out what is causing the error and it says:

On Fri 11/18/11 11:43:22 AM GMT your computer crashed
crash dump file: C:\Windows\memory.dmp
This was probably caused by the following module: rt86win7.sys (Rt86win7+0xCE8A)
Bugcheck code: 0x4E (0x7, 0xCF7B5, 0x1, 0x0)
Error: PFN_LIST_CORRUPT
file path: C:\Windows\system32\drivers\rt86win7.sys
product: Realtek 8101E/8168/8169 PCI/PCIe Adapters
company: Realtek Corporation
description: Realtek 8101E/8168/8169 NDIS 6.20 32-bit Driver
Bug check description: This indicates that the page frame number (PFN) list is corrupted.
This appears to be a typical software driver bug and is not likely to be caused by a hardware problem. This might be a case of memory corruption. More often memory corruption happens because of software errors in buggy drivers, not because of faulty RAM modules.
A third party driver was identified as the probable root cause of this system error. It is suggested you look for an update for the following driver: rt86win7.sys (Realtek 8101E/8168/8169 NDIS 6.20 32-bit Driver , Realtek Corporation ).
Google query: rt86win7.sys Realtek Corporation PFN_LIST_CORRUPT

Google could not find any update for the said driver, nor it gave any other solution. Kindly tell me what should I do know to get rid of this problem??
