External HDD WD 2,5TB doesn't show up in My Computer

Hello, 
My External USB Hard Drive doesn’t show up in My Computer Win 7 64bit. 

I’ve just received my Western Element 2,5Tb today. When I first plugged it in, it worked normally. But due to my over-excitement, I copied too much files at the same time and it wasn’t working anymore. I regretted doing this immediately. 

I have searched on the internet to find some solutions but all of them didn’t work. I’ve checked the Computer Management, Disk Management, but nothing about my External HD showed up. In the notification area, my laptop still detected it and I can removed it properly [even though i can’t use it at all]. 

I tried to connect to my USB and another Samsung 500Gb HDD. And it worked perfectly fine. 

Then, I tried to connect my new HDD to my sister’s lap [she is using Window Vista] and it worked perfectly fine too. 

I don’t know what to do anymore. Please help me.

Go to device manager and see if you can update the drivers

restart the computer with the drive connected

And when i tried to change the drive letter. 

I tried to change the Drive letter but it didn’t work.

I don’t know what to do anymore. 

Try deleting the drivers for the drive and SES driver then remove the drive and reboot PC and reconnect the drive. It should load fresh drivers then.
