So I am working on a client laptop, a Gateway NV53 model MS2285. Came to me with boot issues, specifically booting to a black screen on power up, no post, no nothing, and it only did it sporadically.
Well, I did find multiple sources for this issue online, but ultimately it came down to a motherboard issue with the onboard graphics. I ordered in a new motherboard and battery (as it needed one), got it installed and back together and everything worked fine.
Got the computer back a week later with a new issue. It would crash to a black screen at random intervals during video playback. No rhyme or reason about it. I observed it was getting hot so I assumed a heating issue as it was getting extremely hot. I ended up RMAing the motherboard and getting a new one. With the new one I was still getting the issue though it was not getting nearly as hot as before.
After troubleshooting with SpeedFan and the crash, I found the system to be running slightly hot, but there was no baseline for a temperature crash. The temps during the crash never went above 70C and it sometimes occured far lower than that.
Event log gave little to no information and there were no dumps for the issue. The only thing that seems to be common with the crash was an event Ati2mtag before the crash, but it seems the event logs continue even after the screen crashes up til I do a hard shut down. I reinstalled drivers and messed with settings to no avail.
I tried new memory modules to no avail as well as a barebones start, still had the issue. I then got it running, ran Windows updates to install new video driver, and the system went black during the Installing updates part of the reinstall, first time the crash occured without video playback.
I wanted to rule out the HDD, and a bad install, so I tried a new HDD and a reinstall. Got into Windows and within a few minutes had the crash. Hard reset and got to boot options and keyboard would not respond and Windows did not successfully load. Hard reset and the system hits a black screen again - no post, no nothing. All the way back to ground zero.
I've tried to power cycle the laptop, barebones start, and a plethora of other combinations and I'm at the end of my rope. No matter what I do, old HDD or new, old memory or new, power cord or battery, just a black screen on start.
Is this laptop just that screwed up or is there something I'm missing in all of this? Desperately in need of direction.
