Bsod ntoskrnl.exe Help

[Claudiu]

Hello all. I have some problems with my pc and i dont know what is the problem. Lets start with the begining... I install fresh copy of win 7 x64, and it can work for a week or 2 without giving me bsod ntoskrnl.exe, but, if I let the pc in to idle mode, like i just open the pc and let him run alone for 10-20 min i get the bsod, and it always the same first bsod error code, cuz after the first i get a lot more bsod errors...
The thing is that if i get bsod or not, i dont know why I cant get a iso file from the archive, like gta 5, has 60gb iso in archive. I cant remove it, i always get errors, and it happends with all archives bigger then 4-5 gb, the lower ones i try a few times and it works. I have even problems with installing the games bigger then 5-6 gb, i get error crash, could be at 2% or 99%, but after a few tries, here depends on the iso file, how big it is, it will install my game... another thing is that after fresh install of win, i feel like my pc is running a lil bit slow, i know my pc how it should run, but after the first bsod is running good. I have format the Hdd but no luck. Now i have only 1 bsod given, but ill rite here a few files that ill get the future bsods. Some friends say is my hdd bad, some my ram, i have a zeppelin 4gb at 1333....
Other bsod files: win32k.sys Ntfs.sys dxgkrnl.sys.
I feel like i need to change something in my pc, but what piece? Please help me. The bsod.txt file contains the other bsod i get....
