As I dont have the original bios backup for this motherboard , I reprogrammed it with a dump from Internet. Surprisely It worked, BUT the cooling fans are running at full speed and the service tag is not saving in BIOS SETUP at all ( I can't get out of manufacturing mode active alt+f)

Sorry for that, but I certainly think CPU is bad/damaged. I know It's hard to detect the problem. However, you should notice some OVERheat on it in a very short time (when the power button is pushed
). Put a drop of isopropyl alcohol on die and you'll see......Last edited by latinphoenix7; 07-25-2018, 03:32 PM.Leave a comment:

Re: Northbridge TEST
Hello again!
I've also heard other way of knowing when a northbridge is faulty is if one or more of the capacitors on it has/have a resistence value less than 30 ohms.
they'd usually have a much greater value
Does anyone have an experience/comment with this test?
I just tested my NB and really some of the capacitors have aprox. 400 ohms and the others have 1, that is, open!

Test Mosfet Gate with DMM
Hi,
After reading the following post:
[url]https://www.badcaps.net/forum/showthread.php?t=14147[/url]
He says that "[B]when you read the gate you always read between gate and source[/B]"
Is he refering to reading voltage between gate and source??
Also, He says [B]"You aren't going to get any useful readings from the gate unless you have a meter with frequency reading"[/B]
Okay, I have one. Now, how could I test the gate with my DMM?? How do I read the frecuency?
I guess if I test the gate,... -

Northbridge TEST
Hi all
Is there a way of testing a Motherboard Northbridge ??
I've heard it should be checked the smd capacitors placed in CPU Socket as well as a mosfet near Northbrigde.
What is your opinion??
Thanks in advance
