    My PC was running fine yesterday morning when we had a power cut. I switched the power off at the wall and went to work. When I got back the PC failed to boot. No lights, completely dead.

    I removed the GTX 1070FE to take the cmos battery out. After 5 mins I refitted the battery and tried the PC, which now appeared to work fine. I then refitted the GPU and the PC again refused to start.

    It looks like the card is dead, although there's nothing obvious that's gone pop on the GPU PCB.
    Are there basic fault finding operations that can be carried out to maybe locate the fault using a multimeter. I've got the soldering skills to replace components if necessary.

    Thanks

    Most basic thing would be test the gpu
    In another pc
    A friends if you don't have a second pc
    Though in the current situation going to a friends might be difficult I guess
    Though if you were out exercising and left it on their door step etc :)

    The 1070 fails to function in my backup PC, and the backup 780Ti works in my main rig, so it looks like I'll be prodding at the 1070 with the sticks. :(:(

    Gutted that something so expensive can be so disposable.

    That's the problem with society today
    Replace rather than repair
    Sadly it's probably a very cheap repair if you have the knowledge to diagnose the fault
    Had it years ago a capacitor failed but luckily found a local guy who fixed it for a few beers
    But most places now just don't do pcb level repairs or if they do they want more than the items worth

    Louis Rossman's YouTube electronic repair vids look very good, but he doesn't specifically repair a GPU in any of them from what I've seen. I want to get into it at some point, but then I'm not generating enough faulty electronics on a daily basis to get good practice at it.

    And another thing........ I like the way the way the machine waits until after OCUK's 20th anniversary and a now a price rise due to shortages before it decides to go phuutt!!:mad::mad::mad:

    Removed the 780Ti from my backup machine and fitted that. Wow! 83 degrees when running VR has turned it into a hotair gun.:eek::eek::eek:
