Could this be my Power Supply?

Leatherneck · Post by **Leatherneck** » Thu Feb 08, 2001 6:24 pm

I just put together a KT7 (non raid) and a T-Bird 850 system. The thing is freezing up about 3 times a day. When this happens, I have to reach behind the case and cut the power. I can not hit the power button to re-start. The powere supply isn't top notch, but it is a 300 watt AMD approved supply. Could it cause freeze ups like this? Other than this problem, it flys!

KT7
T-bird 850
128 Kingston 133
540 extreme
SBT/TV PCI
SB64 (no legacy)
2 ethernet cards
ISA scanner card (never had a problem)

Thanks for the help

I doubt it is the power supply, but I wouldn't rule it out. Get a hold of Motherboard Monitor, and check out all the voltage levels. If anything is out of whack, it will tell you.

As for restarting, rather than reaching around the computer, just hold in the power button for 8 seconds, and it will power off.

I had some problems with a netgear net card causing me to freeze up.

What kind of network cards do you have, you might want to try taking out some card to see if you still get the lock ups.

My guess right now it would be the network cards, cause i just had a similar problem.

I have 2 nics, a 10/100 realtek for my cable and a Diamond Homefree phone NIC. I took the Diamond out and it still froze periodically. The Realtek chip is so common, I was not suspicious. I have swapped IRQ's, tried every card in every slot (which helped alleviate some other problems) Played with the sound card. It is quite annoying. I sure hope it gets beeter. I am finding myself on my kid's PC in the living room more and more. Home networks are great!

i have same board and power unit and HAD the same problem, try this up your volt settings defaults core voltage 1.750v and I/0 3.30v change to rhis core voltage 1.775v and I/0 voltage 3.50 you can try less and up it bit by bit if you want but the settings i showed seemed the best for me.

There are lots of ways that causes lockups.

What you would like to do is to create a checklist of factors that migh caused your lockups. Let's do a process of elimination:

Here are a few tips:
Overheating causes lockups
IRQ conflicts
Failing powersupply
Software conflicts
hardware incompatibility
Firmware
Bad memory chips
Bios needs updating

Like what I always say...it's best to start with minimum configuration until you figured out which device causes your lockup problem.

Try to remove or replace one item at a time until your problem disappear.

I hope this helps.

i say check the memory, video card drivers and settings, and try setting agp to 1x if u use an agp card...

i donno about this, Just to let u know that u might want to try holding down the power to shut off the power instead of reaching the plug....that's how my ibm works

sounds like corrupted files in power management, try reinstalling windows.

My computer has power problem too. Everytime I shut down my computer, wait for around 10 minutes or more, the computer won't start when I press the power switch. Then I have to turn off the power switch at the back and turn it on again and repeat, until I can turn the computer on by the front power switch. The motherbroad has power through it, and I just don't know why this happens. When I can turn it on, all voltages are normal and there is no problem at all even I keep it on for 2 days. The only problem is cannot always start it up. I am using a Athlon 800mhz on Asus A7V motherbroad with a 300watt power supply. Anyone can help me??

On the not starting issue with the power supply. Make sure the voltage setting in the back of the supply, the one that is for U.S and European is set properly, not in between settings. I had one supply get to me that it was set kind of in between the two. Usually it is a red kind of dipswitch. It caused me a similar problem. You could also have a faulty on/off switch. Make sure your power cord is good also. I know it sounds silly, yet some of them don't seat in all that well and could make and break contact. The only problems I have had with power supplies is the fan taking a dive. Uusually when the supply goes bad you will smell the to well known component burning smell. I am sure it could rise and drop voltages also without you knowing it. As for the machine freezing up and not restarting, that is a strange one. That could be a power supply warming up to much and having to cool down to restart. Maybe flipping the switch causes a break to get you in there ahead of time. Doesn't sound like a power supply problem though.
