First, my computer specs-
i5-3570k(never overclocked yet)
MSI-z77-G43A motherboard
G.Skill Ripjaws 1333mhzx16gigs(2x8gig)
Gigabyte GTX 970
Samsung 840 pro SSDx256 gigs
Rosewill 650 watt PSU
Rosewill Challenger U3 Case
Ok so about 2 weeks ago i noticed my computer would start to reboot about once a day or so. I figured it was some background program updating or something and causing it so I didnt worry about it.
Than last sunday I came back and my computer would not boot/post. It would fire up, spin the fans for about 5 seconds, then shut down and reboot again, over and over and over. Figuring I was planning on getting a new PSU anyway. So i pulled the PSU out of the computer and put it into another computer I happened to have that I was working on for a friend, a Dell Inspiron somethin whatever. It only needed 1 4 pin cpu power connecter instead of 2, and it ran DDR2 memory...it was an AMD board and im sorry im not that familier with AMD(at all)
Anyway, I plugged in the powersupply to the Dell and it powered up just fine. Boot, post, everything. So I figured the PSU was good and the motherboard had died. It being an entry-level MSI board 2 years old, I figured it was very possible. So I scrounged around and managed to find an Asus P8Z77-V motherboard on newegg for 50 bucks. Ordered, arrived, installed.
Nothing. No bueno. Same problem as old motherboard. Now I'm really thinking its the PSU. So I run down to Fry's and buy an antec 850 HCG that happened to be on sale for 75 bucks(thank you Jesus). Pretty nice PSU, much better than the old rosewill PoS, and I needed a new one anyway.
Bring it back home, rebuild computer with new PSU and Asus motherboard, fire it up, bam, everythings fine. Ran for about 8 hours last night.
THEN this morning I go to fire it up, boots up to windows. Cool. I plug in my usb 3,.0 external HDD. Instant freeze. Reboot, wont post. Commence hair pulling out and much crying and gnashing of teeth.
So I pull everything out except the memory, CPU, and keyboard/mouse. Fire up, get it to post, go into bios. Bios keeps freezing aboiut 25 seconds in. Reset bios, finally get it to post, same thing.
Pull out memory modules one at a time and get it to post. I burned a copy of memtest 86+ onto a thumbdrive and run memtest.
So heres where I'm at now-
ONE memory module will not post at all. Motherboard fires up but will not output ANY video on ANY output.
THE OTHER memory module WILL post, gets into bios, whole nine yards, but still random freezes. I got memtest 86+ to test it, and it freezes in the middle of test #6 with over 80 errors.
So now I'm thinking its the memory. Just for S*** and giggles, I decide to fire up the old motherboard, the MSI z77-g43a with the new PSU. Sure enough, IT FIRES RIGHT UP. Running memory test on BOTH memory modules right now. -Froze during test #7-*
*(Apprarently their is a programming error in using multi-cores with memtest 86+. Running the program in single core mode fixes the issue, and it passes test #7)
So thats where I'm at and I'm wondering if I missed something. Obviously I think theres a couple of possibilities-
1)Asus motherboard is bad
2)Memory is bad
3)CPU is bad(I think this is unlikely as temps never reach more than 50 degrees C)
4)Memory campatibility issue between G.Skill memory and Asus motherboard(this is plausible because I dont believe the memory is on their "approved vendor "list. However the memory is not on MSI's either and it works fine
The msi board(the original board I had thought was bad) appears to be working with the new PSU. Im going to continue to run memtest(seems 24 hours would be a good measure).
Is there anything else I missed or any other tests I can run? I'm thinking of returning the asus board but I'm really skeptical the MSI board is truly good. Ironically as of now it appears to be functioning better than the asus board.
yes I breadboarded both motherboards before putting them in the case as well.
Thanks in advance for your time guys and sorry for the lengthy post.
