PC Occasionally Restarts, BSoD, or freezes

So, I moved back from working in China in the middle of last year and I brought my PC I bought there with me. My dad gave me his old Dell XPS 9100 and I merged some of the parts (HDD & RAM) together. The first couple of months it was super fast, no issues at all. Then after a couple of months it started waking up from a hard off (hibernation or cold start) it would restart once or twice before staying on, but then there were no issues once it was up and going and that would happen every time.

After a couple of months of that it stopped restarting 1-2x every time at startup (but on occasion would still happen 1x), but I started to get the occasional BSoD with WHEA Uncorrectable error and one other one that I can't remember (sorry! But it was something about time or a clock? that one was less common).

Now the BSoD is less common, but it will occasionally restart in the middle of benign tasks like opening a second tab in Chrome, with no other programs running at all. Yet I can play games on Steam for hours and it's fine.

Then, one night I was watching YouTube videos when I fell asleep and woke up to the monitor with a frozen image of the video still on screen and had to hold the power button to force the computer off to get it to restart. Now it seems to be the only error anymore.

This is such a wide range of symptoms and my level of tech skill is just as an occasional hobby. I asked on reddit about a month ago: https://www.reddit.com/r/techsupport/comments/84zsi2/pc_occasionally_restarts_bsod_or_freezes/. The only suggestion was temperature. I took the side panel off and made sure it wasn't overheating. It restarted earlier tonight while I was using it and I checked seconds afterwards and it was barely warm. What can I do to narrow down the possibilities? I have Ultimate Boot CD installed on a USB that I used to fix my laptop a few years ago, but that's the extent of my knowledge on diagnostic software (and I only used Vivard 0.4 to remap the bad sectors). I did that and nothing.

My build is Windows 10 Pro version 1709 (Build 16299.309) XPS9100 (original HDD replaced and added to original RAM) Intel i7 930 @ 2.8GHz 10.0 GB RAM AMD Radeaon HD 5670

use hardware info set it to logging and sensor watch your 12v rail make sure it holding. on the mb as it a few years old check for leaking or swollen caps. look at the part number and model number waved on the mb. google it see if there been issues for cap failures or recalls or class actions do to high failure rates.

How do I locate the specs for the original parts? I tried creating a PCPartPicer list, but I got stuck on the cooler and it wouldn't let me continue without it.

I'm not sure how to identify certain parts that came pre-installed. Also the HDD and RAM I installed from my disassembled PC I would need to identify as well. I would be happy to provide the info for all of them if I knew how ^_^;;

Generally the most common culprate for restarts is the PSU. Do you know the model number of that? you will have to look inside your pc, as the PSU is impossible to find using software (as it does not interface with the pc itself).

Good advice, but for hardware info it doesn't report accurately, as it has to go through a lot of stuff on the motherboard before its measured. My perfectly good rm750x is out of spec according to hardware info its completely out of spec! To measure, run your PC under load and grab a multimeter. To test the 12v and 5v rails, connect one lead to the 5/12v cable and the other lead to a ground cable. The voltages should stay within a few percent of 5/12v.
