BSOD in random times

Hello,
i'm new with this and i'm sure I have some hardware problem but I cannot figure out what is it.
I tested ram memory and it passed. I tested hard disks and I found 4kb of bad sectors, on one hdd (maybe this is problem?).
I uploaded minidumps so you can analize.

Thanks in advance

i think this is all

Are you over-clocked?

not overclocked

one more interesting thing - it happened each time when i'm on internet

All dump files indicate 0x124 WHEA error which is basically telling you its a hardware error (but this is not always the case)
All state BUS error which is likely CPU/mobo related, but generally its the CPU catching the fault and reporting it so can be misleading
Things to try

Update bios to latest
Reset bios to optimised defaults
Check all internal connections, unplug and replug if necessary
Reseat all RAM
Update SSD firmware if your using one
Update/reinstall chipset drivers

If all else fails try disconnecting all accessories and running with just ram/cpu/hdd and cooling fans

pauly will memtest tell me if its ram memory?

i did mem test and it passed

memtest dont show any problem with memory.
i thought it is maybe intergrated network card so i disabled it but my windows crashed soon after.
After re installation i still have problems. i also unpluged hdd with 4kb bad sectors and still crushing.
i noticed it crashed almost all the time on internet while i use some adobe flash aplication

in bios i have voltage to each:
cpu voltage 1,25
3,3 voltage is 3,285
5 voltage is 5,088
12 voltage is 12,096

are voltages good?
