Recently i upgraded my CPU i5 2500 to i7 3770 and then starts the niightmare..
When i force my GPU using FuMark for 5-10 secs my pc sunddely restarts. I'm running out of solutions..

My config:
Gigabyte GA-B75M-D3H DD3 1600MHZ USB 3.0
Intel Core i7-3770, Clock 3.3GHz, Cache 6MB
Geil 4GB DDR3 1600 MHZ ENCHANCE CORSAIR
CX Series 550W 80 Plus Bronze - CP-9020121-WW
Galax OC GeForce GTX1060 6gb

I also tested with another GPU(r7 260x), but the problem persist..

Here is what i already tried without success:
-memory's looks good with memtest
-reinstaled windows 10
-Changed the memory's frequency
- Enable/Disable XMP
- Enable/Disable Turbo Boost
- Clear CMOS
- Reassemble/ Clean all the components
- Reinstalled GPU Driver (DDU)
- CPU / GPU temperatures 40ºC~50ºC

Any help will be great :)
Cheers guys

If you rig is already resetting during games, then using an even more stressful testing utility seems pointless...

You can borrow/try another PSU of more than adequate wattage...(most adequate 550-650 watt units of decent quality are only $55 -$60, although someone will be in to recommend a 430 watt unit shortly at higher cost, I'm sure, undoubtedly equipped with a 'Super Platinum' name, etc...)

Then another GPU...

Some motherboards' regulators fail occasionally at being able to supply adequate and quickly change current/voltage (up to 75 watts, I believe) to the GPU thru the PCI-e slot...

Some of FurMark's tests in years past were notorious for causing such rapid shifts in load that voltage regulators in GPUs and/or motherboards would fail/reset/powercycle/freeze/lockup but, only during that test, and in no other application or test...

If that is the case here, I'd question it's usefulness, or the usefulness of trying to 'fix' it with a different PSU/MB/GPU combination....

I have only my old GPU to test it...

Before i reinstall my windows, i made some tests running games like BF1 / BFV with no luck either.

Can you suggest me another application to stress my CPU/GPU?
Meanwhile, i will download another game to check again.
