This saturday i upgraded my pc and mb from athlon to phenom 9550 (gigabyte - GA-MA770-ds3)..

From the first time i booted the machine got rebooted immediately after the os selection menu...

I thought it would be some s/w issue.. and was just googling about this issue in my laptop... and it looked like overheating could be a problem...

So i removed the case turned on the a/c and allowed it to cool... only after that iam able to boot it, if i turn off the a/c the pc just restarts in some 10 mins.. and after that no way it can get to the OS logo screen itself (just rebooting automatically )

So this is the problem ... t pc is just rebooting immediately and right now iam debugging it as overheating could be the issue (with my findin i feel its very likely)..


can some one please HELP me out of this issue...

If you go into the bios when you first turn on the machine, somewhere in there it will show the temp of the cpu, could you check that and report back. Also when you replaced the cpu did you use the same Heatsink or did you use the one supplied(if supplied) with the new cpu.

5311Mhz Validation

cpu temp is 45-47
Iam using the same heat sink that came with the processor...

and also one more thing my the cpu fans rpm is always < 3000 is it normal.

because i remember that in my previous processor the cpu fan was higher....

Is this a fresh or repaired OS install or just a plain motherboard+CPU swap?

-------------------------

only a motherboard+cpu swap

The same os i installed on the previous configuration... xp some how managed to adapt the hardware change..

it is highly recommended to do a fresh install

the more changes you make, the less likely it is that windows will be able to adapt. the reason is that during install, it loads only the drivers necessary to run your current setup. it needs different drivers (from the cd) to run certain things. you can try a repair, but it's usually going to format everything anyway.

the best way to import your old stuff is to either:
a) save a copy and then copy it over using a floppy, flash drive, CD, dvd, or other removable hardware after you've reformatted the hd.
b) if you are installing a new hd, attach the old hd temporarily and copy the data files over (don't copy over windows. there will be a .dll conflict if you have two different versions in the same path.)
c) use the import files and settings wizard (or whatever it's called.) i usually do a), but windows can automatically import your old data to your new computer.

okie then i'll install it again freshly and post the updates...

No iam still having he same problem.... even during the OS install the pc just hangs or reboots in the initial file copy stage itself..... i have to install it wit my air cooler on....


Iam not sure if this is the problem but this seems make my pc stable... one of my motherboard utility was easy tuner pro.. in tat there was a option to reduce the processor core voltage... it was previously 1.250 volt and i changed this to 1.150 volt

with this even when i turn off the cooler it seems to be working fine.. but the problem is iam now facing the problem in linux... cos i din find any linux equvalent of this tool..

any suggestions ???

you can change the voltage in bios: http://forums.amd.com/forum/me...id=98342&enterthread=y
