Hoping you can help me determine what the problem is; I'm 99% sure it's NOT the drive, because it works fine on my other computer...

 

About 3 days ago, my computer started freezing up; cursor wouldn't move, CTRL+ALT+DEL wouldn't do anything...nothing to do but hard shutdowns.  At first it happened after about 60 seconds of use, then it got to the point it wouldn't even boot up...the screen would be dark gray/black; not "off", but as if it was displaying a solid black image.  This was random...sometimes you'd reach the logon screen, sometimes not.  Also, sometimes the fan would kick into a really high speed, but there was no heat coming out...the computer wasn't warmed up at all.  BTW, battery was fully charged, and I experimented with "AC brick plugged in" and "not plugged in"..that didn't change anything.

 

When you could reach it, logging in w/safe mode didn't change it...it would still freeze within 60-90 seconds.  After 30-40 tries (what happened on startup was sporadic, so I was hoping I could get it going at least once)...I put it aside for the night.  Next day, it launches up GREAT!!!!  I open up & start to backup some photos to my external drive...it's working for about 4 minutes...then it freezes.  Then it's right back where it was the night before, so I remove the drive, put it in a case & plug it into my desktop via USB, I get full access & backup all my files fine.  BUT, before I did that, I plugged the USB into the laptop & it actually took me to the screen where you can choose safe modes or normal...I click safe mode, the little bar-graph at the bottom is at about 70% of loading the system...then it freezes (before Windows even opens!!).

 

So I think I'm at the point where it's either the motherboard, CPU or the power supply (but that's ON the motherboard, isn't it?).  Motherboards are $200-300 on ebay...definitely worth it at this point vs. ponying up $1300 for a new G-series.  But is there any way for me to verify exactly what the problem is?  Could it be something OTHER than the motherboard?  I'm thinking I might be able to pull some dump logs or other logs off the drive, if that helps (which ones??).  But I tried that early on, when I was getting 60 seconds of access before it froze, and most of the errors were about the hard shutdowns...I couldn't see anything that looked like an 'underlying cause'.

 

Thanks for any help you can give me on this!!
