First of all my pc components are:
PSU: Fortron FSP Raider 650 ATX 2.3 85+ 650 W
SSD+HDD: OCZ Vertex 3 Max 120 GB IOPS SATA III 2.5", WD Caviar Green 1.5 TB 64 MB
GPU: Gigabyte AMD/ATI Radeon HD7970 3GB
RAM: Kingston 8GB PC14900 DDR3 CL9 Hyperx kit of 2
CPU: Intel Core i5-3350P 3.1 GHz 6MB LGA1155
MOTHERBOARD: Gigabyte GA-Z77M-D3H (rev. 1.1)
Bought PC back in February, and till now my pc was in warranty 4 times, they always saying, that there is no problem at all... but I still have it.
Symptoms always are same:
When playing games after some times pc crashes.
And always same - (just before crash always hear some crazy noise. Even don't know to describe it. Sounds like when needle touches vinyl, something like that crackle) So video freezes, usb keyboard and mouse disconnects, sounds gone. Needs manually to reset via rest button.
Myself and in warranty make gpu stress test - gpu fine, tested ram - fine, tested sdd - read/write was good.
I don't know what to do next
My suspicious are that still something not good with gpu, because pc crash always, when gpu have more work - games. Or maybe something wrong with motherboard - but I don't have any idea how to test motherboard.
Any help and thoughts very welcome. Thanks
Bad power being supplied to your PC by the electric utility? Try using a line conditioner or UPS to prevent voltage sags and brownouts.
A guy brought over a pc of his for me to fix once. I ran it for days, stressed it out, never had a problem with it. I suggested maybe he was getting voltage sags. He hired an electrician to test his house power and found no problems, brought it back. I ran it for days with no issues and gave it back to him. "I can't find anything wrong with it. There is something different from your place to my place that we aren't including with the testing" He took it back home and ran it without plugging in the mouse and keyboard and it ran fine. He plugged in the mouse and no problem. He plugged in the keyboard and within a few minutes it crashed. He called me up and asked if the keyboard could be causing the problem. I had no idea, but told him to go buy one since that seems logical. He bought a new keyboard and problem solved.
