Hullo technological friends! ----- EDIT: I have since swapped out the 770GTX with a 1660GTX Super, and the same reboot problem occurs. Although I initially went of bad GPU RAM error, the video card isn't the root cause of this reboot issue. ----- ----- EDIT 2: My gaming rig appears to be stable after swapping out the PSU with another I had in another computer... sooo looks like a relatively new PSU was the culprit. Still early days, will update as I get the chance. Although Benchmarks have been passed, I'm still to have an all nighter gaming session to really test it. ----- i7 2600K GA-Z68X-UD4-B3 (latest BIOS) Samsung SSD Hard Drives Thermaltake (Gold) Power Supply - (newest component, at least 3 years old). 24GB RAM GTX 770 (2GB RAM) Video Card Fan Air Cooling Windows 10 - 1909 I've been having crashes on and off and on and off for a couple of years now. Things settle into a routine where I can do graphical intensive work no problems for weeks on end, then POW, non-stop random crashes/glitches where I give up on what-ever-it-was-I-was-doing in the land of 3D (games and game dev) and return to watching youtube and doing real world things like patting my cat. Anyway, Risk Of Rain 2 came out which stirred my interest in video games again, but after a solid couple of weeks of playing without issues, my system started crapping out. Bugs include; - Graphical Artifacts - Hard resets - Apps crashing to desktop - Laggy graphics whilst running the most basic 3d apps to the point of app failure (works, but gets slower and slower...) More and more I've been suspecting GPU, whilst also acknowledging my rig is getting a dash old and has half survived lightning strikes over the past 8 years (with a dead onboard NIC to prove it). But not having $$$ to spend on bits that don't need replacing, and also wanting to avoid e-waste, I'm keen on targeting the actual component and addressing the actual problem. Which leads me to this screenshot I took just now; - 3D Mark was chuggy as heck - Temps are fine, nice and low. Erk... posting this now, even my browser is locking up. TLDR; How can I address such a GPU memory error?
