I got this new computer about six months ago:
CPU: AMD Phenom II X4 945 3.0GHz (Quad Core) 45nm, AM3 6MB Cache
MOTHERBOARD: ASUS M4A785TD-V, AMD 785G, Onboard Video, HDMI, GB LAN, iEEE
RAM: 8GB (4x2GB) PC10600 DDR3 1333 Dual Channel
GRPAHICS CARD: GeForce GTX 460 768MB
AUDIO CARD: M-AUDIO DELTA 1010LT
Logisys 600W ATX Power Supply.
I'm running Windows 7 Pro 64-bit.
Almost immediately I started getting the BSOD about once a day. It would also occasionally fail to post, when I turned on the power, sometimes the fans and lights would come on but there was no beep and the screen stayed black (no signal to the monitors). Only after I pressed the reset button would it boot up. It would ALWAYS boot up after I pressed the reset button.
Finally, the solution I found to keep everything stable was to choose in the BIOS settings "Unleashed Mode" to disabled. Which also meant that it would not unlock the CPU's 4 cores (another option that I had to leave off)
Now I'm the first to admit I don't know much about overclocking (I do have a relatively firm grasp on computer operations in general though). But since these days overclocking is made pretty simple, to where the manufacturers offer preset configurations, I thought that I should be taking advantage of this.
Whenever I did have the "Unleashed Mode" on, I would choose all of the various options as "Auto" and if asked for a choice in speeds I would choose a medium speed. But even that caused BSOD and the problem of booting up. I used a utility called "Blue Screen View" and I adjusted the settings in the BIOS to save the minidump file in the correct location. But for some reason the minidump file never gets written/saved so that utility is useless to me.
A couple of the BSOD messages would sometimes read:
"Driver IRQL Not less or equal"
But most of the time there would be no specific message besides the generic one.
I was willing to leave it alone, but now a new problem came along and my indicators are showing that only 3 of the 4 cores are operating. I am using a Windows widget "CPU Usage" and also a program called SIW, both telling me that the 4th core is not working. (As I said this is a brand new problem, all 4 cores were working before today)
I know this is going to be a tough one to figure out and I probably need to give some more specific information, but I'd really like to be using my computer to it's fullest (but still safe) potential.
Thanks for any help or suggestions, and please let me know if you need further info.
