Trying to troubleshoot desktop problems.

[WinterIce8]

I have been having some problems with my rig for the past few days.  I've been having problems up to about a month ago, then my Samsung SSD had a total failure and replaced it with a San disk SSD, then all my problems stopped.  Samsung sent me a new drive and haven't had those problems since. About 2 months ago, I added another 1TB HDD because when I took it to work to run some diag on it, it showed that the one HDD that I had in there was failing, but not quite failed yet.  So I added the other HDD because I was also running out of space on the 1st HDD and was just going to use them both until the other drive totally failed.  The other problem is (and I know most of you are going to chew me out for this) my system is seriously under-powered (I know, I know), I just do not have the money to get a good 850 or 1000 watt PSU.  The reason I have all the parts I do now is because I kept getting handed HDDs and other components and didn't even think about the PSU until I was looking at it and noticed that I only had a 750w sitting in the bottom there (oops :unsure: ), but other then that, since I got a new SSD in there, the system works just fine with no issues.

 

So now, here's my problem that I'm having.  I have been trying to play games and use other programs, and they keep crashing on me for no apparent reason, or I'll open and use one for a while, then close and try to reopen it and it's now very unstable.  And now that I installed the update from just a few days ago for Windows 10, now my video cards are showing as a removable device as if it was a USB flash-drive or something, which makes me nervous.  Other then that, the system runs very stable, I can use programs from my SSDs and other HDD without any crashing.

 

Now my question: are my problems caused by my failing HDD, or the lack of power, or both?  Or could it be an issue with something else like other hardware or cabling?

 

Here is a picture of my rig and if you need to know the specs, they're on my profile.

 

Thanks in advance for any feedback
