Hi everyone, I have a GA-MA790X-DS4 motherboard with F10D bios and I am currently running a 960t cpu clocked @ 3.7 with northbridge clock @2.2 I have a MSI Twin Frozr III 6950 2gb unlocked to 6970 and clocked @ 900mhz core and 1325mhz memory. My problem is for the past 2 weeks now or so, my system would crash and sometimes recover and says that video card driver crashed and has recovered. I have reinstalled and reinstalled different drivers and even using driver sweeper each and every time but sometimes it still crashes. Every time it crashes it sometimes resets my pc or it recovers from the crash or just freezes up. When it recovers, my pci-e bus speed would change from 2.0 x16 to 2.0 x8 to even 1.0 x16. It constantly changes everytime it crashes. I also tried putting my northbridge on auto speed but it still crashes. It started crashing bad one day when my board wouldn't post and make a long beep sound followed by 2 short beeps. I looked in the manual and it says its either my video card or monitor. I took out my video card and it was still the same. I took my sisters video card and still same beeps. I inserted my sisters video card to the second x8 slot and my pc boots up. I took an air blower and blew on the slot and then i tried my video card and it booted up. But ever since then, my system would crash every now and then. Idk what to do. Does reformatting my pc would help? or buying a new board? I also put my video cards bios to stock and it was still crashing. I have a Seasonic 760xp power supply that is plenty enough to feed my pc. Also, this isn't my first time this has happend. When i got this board from swapping with my bro, the bus speed would show 1.1 x16 but then after a week it went back to the normal speed of 2.0 x16. Here is the link from Techpowerup about my question from them. http://www.techpowerup.com/forums/ [...] ?t=170005. Another thread I read here on Toms is about this other guy with an Asrock board: http://www.tomshardware.com/forum/ [...] t-running. So, any suggestions?
 
goto power options in control panel. select high performance.

also make sure you have proper chipset drivers installed

Hey de das dude, thank you for the tip. My pci-e lane is at 2.0 x16. I will report back in a week to see if it is stable. Thanks:)
 
PCI link state power management is there to save energy. when not in use it will clock down to PCIe 1.1 to save energy.
