Windows 10: Budget gaming PC, crashing regularly

Hi guys, I'm new to this forum so firstly I'd like to thank you in advance and please excuse my ineptitude!

I've trawled through hundreds of forums and web pages and typically most of what I have come across is not exactly what my issues are here and now....so I'm reaching out to you folks who know what they are talking about!
I found a useful post here a few days ago (Windows 10 lag spikes/freezes with event errors) and is very similar to what the troubles I am having are.

So, please excuse me if I ramble a bit here.

I like doing a bit of light gaming from time to time and have used the Microsoft Surface from my office so very used to low res games (I play World of Tanks and some of the older Hitman games etc, all played on the lowest graphics settings). After doing some research and seeing you can buy an older PC and upgrade the GPU, I decided to buy a HP Elite 8300 CMT and found a used Gigabyte Geforce GTX 1050Ti OC graphics card. The two went together pretty well and all seemed good.

Until I found it froze up regularly, sometimes (often) completely crashed and restarted after a time.

I have been playing Mafia 3 and Sniper Elite 4 and especially in Mafia, it regularly completely crashes when you are pushing a couple of buttons at the same time (as you tend to do).

I'm really quite green on this, so I'd appreciate your input.

From the post I mentioned above, I've also stopped using Chrome, this also froze the PC multiple times per day.

My system specs are attached from a download I did earlier today from DxDiag. Probably there is a lot of irrelevant stuff in there.

Many thanks, I look forward to hearing from you.

:)

 

all games crash!

I suggest you run rthdribl > http://www.daionet.gr.jp/~masa/archives/rthdribl_1_2.zip
Increase the window size step by step and watch your vga temps permanently.
What happens?
If it crashes, run at stock speeds as suggested before and retry.

P.S.: When your system locks, does the display signal turn off after a time?
Stuttering sound or no sound at all when freezing?
What X1800XT model do you own exactly?

ive watch my temps and both the cpu and gpu are within normal ranges. when it freezes it simply freezes the image and stops the sound. i must reboot to get back to windows.
