Hello
Hope someone can help me before I tear out whats left of my hair. Three weeks ago while playing BF3 on line the screen would freeze and I would have to reboot and it will run fine. A few days the pc would reset and/or freeze. Now I get BSOD whatever task I'm doing.
Blue screen viewer reports different bug check string each time but the bad driver is always ntoskrnl.exe. I have ran memtest on each stick ( 1x4 gb and 1 x2 gb) for at least 6 hours on each stick and they pass, put my old graphics card back in but I got DXdiag error, ran Western Digital HDD diagnostics tool and that was ok, reintalled drivers, reinstalled Windows 7 but to no avail.
One thing I have noticed is sometimes when I reboot after a crash the fans spin but pc doesnt boot. If I take out the stick of ram and put it back in the pc boots up.
Temps when gaming: gpu - 65C max, CPU 45C
Now the comp will not post at all. Fans spinning but no beep. Checked PSU and voltages are ok.
Hope someone can help me out.
Thanks in advance
Specs:
AMD Phenom II x4 965 cpu
MSI GTX 560ti gpu
Asus M4A785TD-V EVO mobo
OCZ 600W psu
WD 250gb HDD
Kingston 6gb Ddr3 1600mhz Hyperx Memory

Memtest is not always the solution. Memory can pass sometimes and still be faulty. Try pulling one module at a time to see if the problems resolve. Make sure the configuration positions of the remaining modules is still correct, as in, make sure there is always one stick left in the slot #1 or A1 position etc. Don't just pull a module and leave nothing in the slot that memory would be in if you had only one stick installed or that may create it's own problems. It really sounds like a memory issue but it could possibly be a bad power supply, board or cpu.

Thanks for the reply darkbreeze. I'll run memtest again making sure the stick is in #1 slot and post the result. That's if I can get the comp to boot. I've checked the voltages on the psu and they were as expected.
 


That's not quite what I meant. If you've already run memtest, that's it, you done with memtest. It's not going to tell you anything different than it already has. What I meant was, eliminate one memory module at a time to see if windows starts up without that stick of RAM in the board to see if you have a bad stick that memtest did not catch.

Ah sorry. Anyway I've put my old cpu back in and it seems to be running ok now. Must of been a failing cpu.
Thanks for taking the time to help.
