I have a Dell XPS 435 that's been giving me progressively more trouble over the past month or so.
The first indication of trouble was maybe 2-3 months ago. Infrequently while watching a video the screen would turn to random rubbish (similar to photo1.jpg) and either freeze up or restart. Once I restarted the problem wouldn't reoccur for days/weeks.
Within the past 2 weeks the situation since degraded to multiple restarts or freeze ups every time I turn on the computer. Sometimes it freezes on the Dell startup screen (photo2.jpg), almost always at this exact point in the progress bar. Other times may either freeze or restart on the Windows login screen, immediately after I login, or within 5 minutes of logging in.
Sometimes during the freeze up/restart cycle I will get a dialogue screen prompting me to enter Windows Recovery. This invariably suggests I do a system restore. Sometimes system restore works, sometimes the computer freezes during the restore process. Either way it has no apparent effect on whether the next boot will be the one that stays on.
Once the computer stays on longer than (approximately) 5 minutes, it will not freeze up even if I leave it on all day - as long as it is in use.
However, if it goes to sleep, it will almost always freeze up when it wakes up.
I am really not sure where to start troubleshooting this. I saw in another thread that someone requested a Speccy log so I installed and ran that. Results are here - http://speccy.piriform.com/results/53MmvPfYbLvfS8AHkYhyE7J
I really appreciate any help anyone can provide.
