Hello everyone! This all started maybe a month, to two months ago. Randomly, my computer started getting a blue screen with the following written: "PFN_List_Corrupt". At first I thought it was a harddrive issue, so i ordered a new one on warranty.It kind of worked at first, but right away I could already see it didn't fix the problem. Now, from my knowledge it isn't a Windows problem. I think i know this because i ran a driver verifier and un-selected all drivers that had to do with windows, and it still crashed. It also doesn't let me download certain files, for example : Libreoffice, League of Legends, World of Warcraft, Microsoft Office, Visual Studio, Visio, and even at first it wouldn't allow me to download certain drivers (I have no clue on how I got them to download). When I do try downloading these certain PROGRAMS, it gives me errors such as: Corrupt files, missing files, unable to transfer files, unable to find installer(something along the lines of that), and multiple other errors that I cannot remember off the top of my head. Even when I downloaded Windows 7 on this new harddrive, it had issues. I've re downloaded the OS about 5 times now, and each time it still has the problems. So, to my knowledge, I don't think it's a problem with the harddrive, or the OS, which leaves me absolutely stumped! Here are my PC specs:
CPU: AMD Phenom(tm) II X4 965 Processor
Motherboard: Gigabyte Technology Co., Ltd. 970A-D3
BIOS: BIOS Date: 01/21/13 21:20:14 Ver: 04.06.05
Total Memory: 8.00 GB
HDD: WDC WD1002FAEX-00Y9A0 ATA Device
Sound Card: (1) AMD High Definition Audio Device   (2) VIA High Definition Audio   
Graphics Card: AMD Radeon HD 7700 Series
OS: Microsoft Windows 7 Professional  64-bit 7600 Multiprocessor Free

Any help would be greatly apreciatedHi

What is the make and model of power supply in your build ?

That error seems to be memory corruption, that's NOT faulty memory it's that the data in memory is becoming corrupt also maybe why you can't download those files.

An overloaded or noisy power supply can cause memory corruption.

Hence why knowing what power supply might help.

 Sorry that i forgot to include that . I believe my power supply is this http://www.newegg.com/Product/Product.aspx?Item=N82E16817151095 . And it might be a problem with the memory, but i did run a memory check and it didn't find any problems.
