after looking for solutions on my own and searching the internet without result I hope you can help me somehow:
Since I installed Windows 7 x64 on a new system (I had tried Vista x64 before but I don't like that OS), it keeps annoying me with random BSODs. Meanwhile, I have updated every driver
and peace of software. The strange thing is following: The machine runs perfectly OK for one or more weeks before it crashes twice (either on two following days or within two hours). Then it works fine for a few days and so on (can be seen from the minidump, I suppose).
The BSOD is always triggered by "ntoskrnl.exe" (says windows). And it always occurs when I work with the PC (for downloading and calculation purposes it runs two to four nights a week).
As the OS is installed from a downloaded ISO-file (msdnaa), my first (and only) explanation so far are some corrupted bytes due to the download. I have checked the RAM with memtest yet, but without any result even after a few hours.
The hardware is following:
i7-860 on MSI P55M-GD45
2x2GB GeIL PC3-10667U CL7-7-7
2xSamsung HD502HJ Raid1
HIS Radeon HD4760 1024MB (in second PCIe slot)
Intel 5100agn (via adapter in first PCIe slot)
Thank you very much for your help! (if I made too much spelling and grammar mistakes, feel free to drop a hint )
