Hi sirhiro and welcome to TSF !
The 0x03a61468 address is most likely part of the RAM address range, I'd start by checking your memory. Download, unzip and burn memtest86+'s bootable .iso image file using a burning software that can handle .iso files. Enter the BIOS at startup (repeatedly press del or look for some "press xx to enter setup" message) and set the boot priority to CD-rom first. Leave memtest run overnight and report if it finds any error.
If the ram is fine it could be a faulty explorer plugin or some malware. See this information about 0xC0000005 errors :

If the problem only happens with picture files I'd look for some picture editing software that added some context menu when you click on images.
Use ShellMenuView from NirSoft to see what's the common item that's associated to all those file types. Disable all instances of that application with ShellMenuView or uninstall it and see if it helps.
See if the problem also happens when you start the computer in safe mode (repeatedly press F8 during startup). If it doesn't happen in safe mode then go to start => run and type msconfig. Go to the startup tab. The problematic application is probably in this list. Check bleepingcomputer's startup database to know what each item does and disable the ones you don't need.
