Cpu/Motherboard done for

bradlente

Anybody any experience with this?Pretty sure it's the cpu/motherboard.

Started off with an empty bar flashing under the cog loading icon upon booting and then the laptop switches off.All in the course of about ten seconds.Took out the HD and tried booting the OS from a USB stick,No luck and the same icon.Then tried the disc with no luck.Finally formatted the HD and reinstalled the os on it and now instead of the bar flashing a screen comes from top to bottom.Think it's pretty much the screen of death.

The HD was verified as ok on another system so I'm pretty confident the laptop's as good as ****ed here.Anyone have this kind of trouble before and come out the other side?

Sounds bad. Did you try a verbose boot (cud-v) or a single user mode (cmd-s).

Yeah had no luck there.It's a hardware problem that isn't the HD and I imagine the likes of a fan/battery/graphics card wouldn't completely shut-down the system like what's happening now.
Pretty much diagnosing it as a cpu fail but happy to be proved wrong. I'm more interested at this stage in knowing if there's anything I can do if this is the case or if it's time for a new laptop.From what I've read it's either unrepairable or very expensive,So interested to see if anyone's had anything similar.

Will test some other parts over time if it might possibly not be the cpu/motherboard.

Dodgy RAM?

Only tried the existing RAM in it rotated.Two 4 gig chips in each position and both of them on their own as well.They're a two year old upgrade and I threw my old ones out by accident:mad:

I had problems with my macbook couple of years ago crashing and just playing up. Got it sent to apple shop in new york. Soon as they seen it, it was the ram one apple repair place here wanted to sell me new logic board and wanted 100 euro to check thats what was wrong

Bradlente left it in with me there, I've tried everything I could source on the net about it, but it seems a hardware failure to me too.

I reset SMC/PRAM/NVRAM, repaired and reinstalled the OS on the HDD on another system, and tried to boot internally and externally. Replaced the RAM to check that, and tried to boot the install disc via USB but it fails also.

In single-user mode it hangs at "DSMOS has arrived", and the script solution to repair/replace didn't work, so it must not be .kext file corruption or anything either. Any ideas what else there is to be done? Really seems buggered..

This might resolve the issue - Seems to be mostly affecting the Hackintoshes but however.. Worth a shot! mightnt be hardware related after all

Ah yes, I tried a version of that in the Single User "terminal", to no avail. Also the Install Disc won't boot past the initial stage, same as the OS, so ye can't get that far to try it. Thanks tho!

Bump-So the HD and RAM are both ok,Tried alternatives for both of them and things stayed the same.

Wondering if there's any possibility it might be the optical drive?I never really use it though so it's a long shot.

Doubt it's the optical drive. Mine's mostly broken and hasn't ever prevented a boot.

Yeah it seems to be working fine as well.
