GPU-Z 0.8.7 crash on launch

W1zzard is asking you to test so that he can suggest next steps and be able to troubleshoot the issue you have.
If another version works, it would be one set of steps.
If several other versions also fail/crash, then it would be another.

 

Random crashes/reboots - PSU failling?

I'm concluding that's not a software issue but a hardware one, most likely being the PSU the culprit.

• Power supply in my area has always been very inconsistent in summer time, even experiencing several low voltage situations system wide, with surges making my PC to reboot automatically. Despite PSU's got it's own protection methods, exposing it to several days -and years overall- of unstable electric flow could've inflicted some damage on it. PSU is not near top of the line and it has 8 years of continuous usage (Sentey BRP700).

• I did have random, sporadic reboots over time on my system for a while, even while doing basic tasks (watching a YT video). None prove to be catastrophic until the other day.

• Since the "mayor crash" I experienced the other day while playing a game, that rendered my system unable to install AMD Drivers even on a fresh new copy of a clean Windows 10 , I did experience several random reboots using Microsoft Basic Display Adapter performing basic tasks;
  • At the time of the "mayor crash" I had latest AMD drivers installed and they were working just fine and no mayor Windows 10 updates were installed that day.

• Removing video card (AMD R7 265) and replacing it a Geforce GTS 540 for testing purposes also triggered random crashes and system's lock up (different behavior, but same result nonetheless = system crash). Even while using the Geforce the computer suffered TWO system crashes just by clicking on the "refresh" button on TechPowerUp GPU-Z app. Yet, the third, fourth, ... times I clicked refresh, system did not reboot.
  • Attachment 273658

• Weirdly enough FurMark stress on my CPU and the testing video card -Geforce GTS 540 with Nvidia drivers installed- didn't make my system crash. Yet, opening Chrome afterwards triggered a crash.

I can't identify a system crash pattern.
The only pattern is that when I try to install AMD drives for my R7 265 the system does crash. The rest of the reboots are random and not logical based on the system stress at the moment.

Despite inspecting the PSU -and computer in general- for failed capacitors, I really lack the know-how to effectively detect a bad one unless it's very obviously damaged.

Bottom line: I'm purchasing a new PC overall -time to upgrade anyways- and I expect this to solve my issue once and for all.

I really appreciate time invested in trying to help me, guys!

 

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?
