[rohit09]

Where do I start - OK! I have 2 systems up and running..
Few days ago to one of my PC - I change the 2GB RAM and NVIDIA GT520 card to 4GB RAM and NVISIA GT610. Problem started since that day.. I got blue errors - I check the ram and everything no errors found. If I unrar a file I got checksum error, I got uncompress error even I'm running anything from image..

and the other hand my other PC is just working fine. The same files wasn't show any errors to unrur or extracting from a image file...

what is going on??

When you changed the video card, did you remove (uninstall) the GT520 in Device Manager > shut down > switch cards > start up > and then install the nVidia Drivers fresh?

I formatted the whole system like 3 times already.

Still I got Bluescreen - Because most of the time my motherboard lost the connection with the HDD. Don't know why.. but it happen. I tested the HDD even tested by the WD guys because it has warranty + guaranty.

And the problem described it's still stays.

help need please..
Thanks

Another clue!
(Always best to give as much clear, concise info that you can)

"My motherboard lost connection with the HDD"

• Could be a power issue: check and reattach all power connections, particularly to the hard drive.
• Could be a BIOS setting issue: If you have a modern UEFI BIOS (usually this has a Graphical User Interface) go in and check to see if the main hard drive is set up to "Hot Swap". There is no practical reason to Hot Swap a system drive - so make sure that Hot Swap is disabled for that drive.
• Could be that Windows is shutting down the hard drive in a power saving scheme (this should not occur - but stranger things have happened). Go to Control Panel > Hardware & Sound > Power Options. > Click on "Change Plan Settings" > then on "Change Advanced Power Settings" > expand Hard Disk > expand "Turn Off Hard Disk After" > and turn the time down to zero (it will now say "Never"). Click all OKs to exit.

Let's see if any of that changes anything.
