Ever since I built my computer i've had a problem with it. I couldn't get it to recognize the graphics card, I googled a bit and found that if i restart, hit F8 go down to deactivate signature reinforcement and install the nvidia driver, for some games i would be required to do this it would gave me a direct3d not found error if i didn't.
CPU i5 2500k
MB Asrock z68 extreme3 gen3
HD 60GB samsung SSD
GPU ENGTX560 TI DCII TOP 1GB
RAM 2x 4GB G-skill
PSU Corsair GS800 (800W)
with a coolmaster cpu heat sink
Nothing is overclocked, temps are very low my case has many fans.
Ok so problem would occur like this:
Computer would shut off after couple hours of use, then it would restart itself for about 2 or 3 secs then shut off, then ON then off, this cycle would continue until I intervened. I would shut it off undo ATX cable, plug it back in. Turn it on, hit the cmos switch and or hit the restart, it was different everytime. A lot of the time when I would restart it after a random shut down the motherboard would give mr either a 55, 20, d0. Eventually it would start up after 3 or 4 attempts. For a while it stopped being that way, although i still had to hit F8 and deactivate sig, reinforcment.
Then one day (yesterday) the MB gave me those errors(55 d0 20) repeatedly. So i decided to switch around the RAM. I had the RAM on slots A2/B2, I switched to A1/B1, i could restart like normal computer worked fine for an hour then random shut down, i could start up again with 2 or 3 tries, but it would shut down again, this continued for 6 random shut downs all of them shutdown at different times sometimes immediately after start up and others after 30 min or an hour. At this point I installed windows updates, and uninstalled programs i didnt use, virus scaned, ccleaner the works. Everytime I stressed the computer slightly it seemed it shutdown and restarted itself with an error. I restarted and ran a GPU stress test (FurMark) sometimes my comp would bluescreen most times it shutdown with error 55. I ran memtest 86+ to see if my ram was the problem. I booted memtest86+ on a USB with both sticks and it ran for 20 secs, then i saw a wall of red, then my computer blue screened. I remembered reading somewhere that you are supposed to run it on 1 RAM stick at a time so I powered down left 1 RAM in A1 slot, and the test came back good. I restarted my computer with just 1 stick of RAM, and everything is running great, no problems. Success.
I even ran the GPU stress test all the way through, no crashes. The weird part now is that I dont have to hit F8 ( deactivate signature reinforcement) on startup, which I always had to do. Also every game works fine to be specific league of legends, Dota 2, Age of Empires, CIv 5. This has been a weird experience for me, when I first looked into the problems, I found a lot of people have problems with this Asrock Motherboard. I'm now 95% sure my problem was the ram interaction with the motherboard. I will now experiment with nividia drivers/other RAM configurations to see what happens. If i get brave i'll start overclocking... more to come.
