kernel panic and other issues

Question

Good morning,For over a month now, I have been having intermittent problems with my MacBook Pro (Snow Leopard). If often has kernel panic attacks, when the multilingual message "You need to restart your computer. Hold down the Power button for several seconds or press the Restart button." This sometimes happens randomly after I have been using the computer for several hours without problems, and sometimes it enters a phase when it keeps reappearing upon startup and it takes many tries before it can fully start up again. Also, sometimes the computer seemingly randomly restarts without any prompting or any sign.I have also had a few other problems, which I suspect are related. Often as I am using Google Chrome, the "Aw, Snap!" page appears. Sometimes this is followed by the kernel panic. Sometimes I also have this problem where the application bar at the bottom disappears or other funky stuff is going on with the interface. Finally, sometimes the disk drive does not work -- I would be trying to boot it up from the install DVD right now but some days it won&#x27;t accept any cds at all.Is this most likely a hardware problem? Should I just give up on trying to fix it myself and take it to the apple store?I would greatly appreciate any help!

Hmmm... I just had a kernel panic for the first time in a few days and I can&#x27;t find any file named "panic.log" or anything having to do with panic. Right before the kernel panic, though, I had a problem with the dock and I was able to find a report for that. I have pasted the first part of it below (it wouldn&#x27;t let me do the whole thing). Thank you so much for any interpretation anyone is able to give!Process:         Dock [97]Path:            /System/Library/CoreServices/Dock.app/Contents/MacOS/DockIdentifier:      com.apple.dockVersion:         1.7 (769.18)Build Info:      Dock-7691800~1Code Type:       X86-64 (Native)Parent Process:  launchd [93]Date/Time:       2015-04-21 17:41:40.920 -0400OS Version:      Mac OS X 10.6.8 (10K549)Report Version:  6Exception Type:  EXC_BAD_ACCESS (SIGSEGV)Exception Codes: KERN_INVALID_ADDRESS at 0xfffffffffffffffeCrashed Thread:  0  Dispatch queue: com.apple.main-threadThread 0 Crashed:  Dispatch queue: com.apple.main-thread0   libobjc.A.dylib               0x00000001012cbb2d _mapStrIsEqual + 371   libobjc.A.dylib               0x00000001012cb6f3 NXMapGet + 1252   libobjc.A.dylib               0x00000001012ca036 _read_images + 4343   libobjc.A.dylib               0x00000001012e0721 map_images_nolock + 12664   libobjc.A.dylib               0x00000001012c9761 map_images + 1155   dyld                           0x00007fff5fc039c5 dyld::notifyBatchPartial(dyld_image_states, bool, char const* (*)(dyld_image_states, unsigned int, dyld_image_info const*)) + 8536   dyld                           0x00007fff5fc0c849 ImageLoader::link(ImageLoader::LinkContext const&amp;, bool, bool, ImageLoader::RPathChain const&amp;) + 2017   dyld                           0x00007fff5fc04d54 dyld::link(ImageLoader*, bool, ImageLoader::RPathChain const&amp;) + 1188   dyld                           0x00007fff5fc08f7c dlopen + 4909   libSystem.B.dylib             0x00000001007e8e40 dlopen + 6110  com.apple.HIToolbox           0x0000000104af27b1 InitShortcut + 3111  com.apple.HIToolbox           0x0000000104af26b5 SetupMenuTracking(MenuSelectData&amp;, unsigned char, Point, double, MenuData*, unsigned int, unsigned short, Rect const*, Rect const*, unsigned int, Rect const*, __CFString const*) + 286312  com.apple.HIToolbox           0x0000000104c19511 PopUpMenuSelectCore(MenuData*, Point, double, Point, unsigned short, unsigned int, Rect const*, unsigned short, unsigned int, Rect const*, Rect const*, __CFString const*, OpaqueMenuRef**, unsigned short*) + 44213  com.apple.HIToolbox           0x0000000104c19d02 _HandlePopUpMenuSelection7 + 66514  com.apple.dock                 0x000000010005df3e 0x100000000 + 38483015  com.apple.dock                 0x000000010005d8a4 0x100000000 + 38314016  com.apple.dock                 0x000000010005c92c 0x100000000 + 37918017  com.apple.dock                 0x0000000100021b29 0x100000000 + 13802518  com.apple.dock                 0x0000000100015f6a 0x100000000 + 8996219  com.apple.dock                 0x0000000100015d18 0x100000000 + 8936820  com.apple.HIServices           0x0000000102657b8d mshPerform + 1121  com.apple.CoreFoundation       0x00000001013df6e1 __CFRunLoopRun + 520122  com.apple.CoreFoundation       0x00000001013dddbf CFRunLoopRunSpecific + 57523  com.apple.dock                 0x0000000100004774 0x100000000 + 1829224  com.apple.dock                 0x000000010000432c 0x100000000 + 17196
