1 core out of four working on new cpu
Hi, i'm new to these forums but have read quite a few threads. I have a problem that i will try and keep brief.
I upgraded my cpu today from a athlon x2 6000+ to a phenom II x4 925. Loaded up and had a look in the bios and saw it was recognised (w/ all its l2 cache) but couldn't get into windows (7 pro 32bit). After a solid 15 hours of utter frustration i changed the ioapic funtion to disabled in the bios. Now i can enter windows but with only 1 core.
Now i am in windows i see that ioapic function is important for multiprocessor support, hence the one core. Switching back means windows won't load again.
miniXP and the recovery is possible version of linux on hirens bootcd also show only one core regardless of what i have in the bios. So does cpuz , with only that cores l2 cache too
I swapped my old processor back in but after having the new one in i got no love and it didn't work either(this was before i managed to get into windows on the new processor). Kinda tells me that something has been changed that is affecting both chips.
Here is my mobo - MSI Global – Computer, Laptop, Notebook, Desktop, Mainboard, Graphics and more
Note that i am running a am3 cpu in an am2 (no plus) socket motherboard. Could this be a cause of the problem?
I flashed my bios to version 1.2 like is required for the phenom II's a couple of weeks ago and the old 6000+ was running on it for a while too.
I also "upgraded" my psu but i suspect it is a pos. The guy had an i7 with crossfired radeons (series 6, not sure what model) running off the same model power supply though so i'm not sure. It is supposedly 1200w but the amps are only slightly above my old 450w psu. It is however blowing cold air out the back and the old one blew out toasty warm air.
Tried the 2 different ioapic versions the bios has available and neither worked. Hoping for a simple solution. Like i need a new and improved ioapic version, but i really am at a total loss so any help would be greatly appreciated.
I'll also add that about 7 hours ago the whole machine nearly went in the river i was that frustrated.
Cheers
Ben
