hello rohit09, let me see if I can help. First you say you just installed an Nvidia graphics card, what graphics card did you have before that? Also, is this an OEM computer or a custom build?
Both of your dump files show as follows
Code:
MEMORY_MANAGEMENT (1a)
# Any other values for parameter 1 must be individually examined.
Arguments:
Arg1: 0000000000041790, A page table page has been corrupted. On a 64 bit OS, parameter 2
contains the address of the PFN for the corrupted page table page.
On a 32 bit OS, parameter 2 contains a pointer to the number of used
PTEs, and parameter 3 contains the number of used PTEs.
Arg2: fffffa800150e100
Arg3: 000000000000ffff
Arg4: 0000000000000000
Code:
Use !analyze -v to get detailed debugging information.
BugCheck 50, {fffffa80314fc5d8, 0, fffff80002d9ca80, 2}
Could not read faulting driver name
Probably caused by : memory_corruption ( nt!MiGetWorkingSetInfo+2b0 )

Please fill in your system specs as detailed as possible. many times we have to look up a component so having the Manufacturer and model number helps. If this is an OEM computer please add the make and model number. These are the instructions I usually give, maybe they will help.
Please fill out your System Specs
Information
Your System Specs will help us to help you, and doing it in this manner will make them available to all helpers in every post and keep us from hunting for them. We ask that you fill them out in as much detail as possible including Desktop or Laptop, Model number if it is an OEM computer and all components with the Manufacturer and Model number if possible.
If you will go to your last post and click the 'System Specs' in the bottom left of the post, you will find a link to update your system specs. Please fill those out in as much detail as possible, making sure to click save at the bottom of the page. If you would like to know what we would like, you can click 'My System Specs' at the bottom left of this post to see mine. If you do not know what your components are, this will help you accomplish this task.

Please run Seatools, Seagate's diagnostic test. It is better to run the DOS test as it gives more accurate results. If you can't get it to run, you can use the installable Seatools for Windows. Please run the Short and the Long tests. The instructions and download link are on this page SeaTools for DOS | Seagate
If the test passes both the short and the long test, please run memtest86+ and run it by these instructions
Please Run Memtest86+
Information
Please download from this site only
http://www.memtest.org/ in the middle of the page are the Download links, you can download the ISO.zip or the Auto USB Flash Drive installer.zip
Extract the Zip file. If you chose the ISO image, burn it to a CD using Windows Disk Image Burner or any Image burner you may have. If you downloaded the Auto USB installer, extract it, insert your USB 2.0 Flash Drive and take note of the drive letter. Run the installer, select the Flash Drive Letter, check the format box and press next. It will install memtest86+ to a flash drive. You can use either V4.20 or V5.01. Boot from your selected media. If you use V5.01 it will tell you to press certain buttons at the start, please press no buttons. The test will begin on it's own and continue to run until you stop it. It needs to run for 8 complete passes or until you receive an error. If you receive an error, stop the test. Even 1 error is a fail. Each pass tests a different part of the ram and each of the 10 tests in each pass tests something different. It takes a minimum of 8 passes to completely test the ram, more passes are better. It is quite a long test and will take several hours depending on how much ram you have. Due to the time length it is best to run overnight. If you have any questions, please do not hesitate to ask
Please let us know the answers to the questions and the results of the tests. Just so you know, I will be notified if you make a new post. If you edit a previous post I will not be notified. So, just let us know the results so we will know where to go from there.
