Glad to hear that the computer now appears stable have you made a new restore point since applying the fix.
I recommend you create a back up image of the HDD so as to avoid relying on media obtained from elsewhere, Macrium Reflect (free) can be used for this, download from here so as to avoid being redirected to Cnet and potential foistware.
I did notice Krvazlixp in Speccy didn`t know what it was and neither did Google when I did a search.

The Ram only working in single channel mode may be because one of the sticks is in the wrong slot, if you are ok with working inside of the computer, check to see if both sticks are in the yellow slots and get back to us.
To check the output of the PSU we will need a couple of screenshots of HWMonitor and Speedfan, see below;
Download Speedfan and install it. Once it's installed, run the program and post here the information it shows. The information I want you to post is the stuff that is circled in the example picture I have attached.
If you are running on a vista machine, please go to where you installed the program and run the program as administrator.
(this is a screenshot from a vista machine)
Download then run HWMonitor and post a screenshot so that we have a comparison to the Speedfan results, details from here
