Thanks for reaching out to us on HP Support Forums. 🙂 I came across your post and would like to help.
I understand that you have an HP ENVY 700-074 Desktop PC and a blue screen of death appears with an error message critical_structure_corruption.
I would like to know the following information to assist you better:
When was the last time the PC worked fine? Any changes (software or hardware) that were made after which this error may have started?
Does this error appear randomly or while on a specific application?
Meanwhile, I recommend you to perform the following steps to isolate the issue and arrive at a fix:
If this issue started recently then you may perform a system restore to rollback to a previous date when everything worked fine. System restore will not delete any data.
Posta successful system restore if the BSOD appears then please perform the steps as described in detail from this link: http://hp.care/2kr4ulH. This link contains steps to even run hardware diagnostics.
I sincerely hope this fixes the issue. Keep me posted. Good luck! 🙂
