hi all, i just bought a macbook pro 15" a week ago. the only 3rd party software i installed was microsoft messenger, office and vlc media player. no additional ram or memory was added. a few days ago, i got a messenger error message pop up a few times, stating it needed to retart the app. but today, things got much worse. a vid playing on vlc media player froze, had to press and hold the power button to restart the laptop. on reboot, i had a kernel crash. i then ran the Apple hardward test. first run, had this error message: 4MEM/3/4/4000000:2fb5f7d0 then, ran an extended test and a had a different error message: 4MEM/2/4/40000000:01990218 after that, things got worse. dock, finder, front row, preview, safari crashed after the reboot. i have their crash logs. had 2 kernel panics too, here are their logs: Fri May 4 22:35:20 2007 panic(cpu 0 caller 0x001A429B): Unresolved kernel trap (CPU 0, Type 14=page fault), registers: CR0: 0x8001003b, CR2: 0xdba7f117, CR3: 0x00dc8000, CR4: 0x000006e0 EAX: 0xdba7f0ff, EBX: 0xffffffff, ECX: 0x02e5e900, EDX: 0x00464260 CR2: 0xdba7f117, EBP: 0x1400bec8, ESI: 0x7fffffff, EDI: 0x02821384 EFL: 0x00010082, EIP: 0x0013d66a, CS: 0x00000008, DS: 0x02d10010 Backtrace, Format - Frame : Return Address (4 potential args on stack) 0x1400bc98 : 0x128d08 (0x3cb134 0x1400bcbc 0x131de5 0x0) 0x1400bcd8 : 0x1a429b (0x3d0e4c 0x0 0xe 0x3d0670) 0x1400bde8 : 0x19ada4 (0x1400be00 0x1 0x1400bf08 0x10616027) 0x1400bec8 : 0x130392 (0x2821384 0xffffffff 0x7fffffff 0x1400beec) 0x1400bf08 : 0x195a42 (0x1400bf44 0x0 0x0 0x0) 0x1400bfc8 : 0x19b21e (0x2afc9e0 0x0 0x19e0b5 0x2afc9e0) No mapping exists for frame pointer Backtrace terminated-invalid frame pointer 0xbfffeec8 Kernel version: Darwin Kernel Version 8.9.1: Thu Feb 22 20:55:00 PST 2007; root:xnu-792.18.15~1/RELEASE_I386 ********* Fri May 4 23:16:25 2007 panic(cpu 1 caller 0x001A429B): Unresolved kernel trap (CPU 1, Type 14=page fault), registers: CR0: 0x8001003b, CR2: 0x00000000, CR3: 0x00dc8000, CR4: 0x000006e0 EAX: 0x0000009b, EBX: 0x00000007, ECX: 0x00000000, EDX: 0x00000000 CR2: 0x00000000, EBP: 0x13fc3e68, ESI: 0x08d39000, EDI: 0x02690828 EFL: 0x00010093, EIP: 0x0019104b, CS: 0x00000008, DS: 0x025e0010 Backtrace, Format - Frame : Return Address (4 potential args on stack) 0x13fc3c18 : 0x128d08 (0x3cb134 0x13fc3c3c 0x131de5 0x0) 0x13fc3c58 : 0x1a429b (0x3d0e4c 0x1 0xe 0x3d0670) 0x13fc3d68 : 0x19ada4 (0x13fc3d80 0x26ef200 0x0 0x0) 0x13fc3e68 : 0x1a1992 (0x2528cb0 0xb0000000 0x0 0x1a26ce) 0x13fc3ed8 : 0x13524a (0x2541f5c 0x2690828 0x2419a000 0x0) 0x13fc3f28 : 0x135533 (0x2541f5c 0x2690828 0x8 0x2416a000) 0x13fc3f58 : 0x13617f (0x2541f5c 0x135eb4 0x0 0x2690828) 0x13fc3fc8 : 0x19ac1c (0x0 0xffffffff 0x10 0x0) Backtrace terminated-invalid frame pointer 0x0 Kernel version: Darwin Kernel Version 8.9.1: Thu Feb 22 20:55:00 PST 2007; root:xnu-792.18.15~1/RELEASE_I386 ********* i have no idea what to make of it, after alot of rebooting by holding the power button, things seem better now. can anyone please advice me and tell me what's wrong? anyone knows what the panic log indicates? let me know if i should post the crash logs for the other apps too. also, what do the error codes in the hardware check mean? any help or advice would be greatly appreciated, thanks so much in advance!
