 Posted: Tue, 24th Mar 2009 19:39 Post subject: My machine will not post *EDIT - PSU EXPLODED* |
|
 |
My machine will not post and I need some help finding which component is causing the problem. First let me start by listing my specs:
AMD Opteron 180 dual-core 2400MHz (939)
Asus A8N-E (bios 1013)
4 X 512 Kingston DDR PC3200/400
Gainward 8800GTS 320MB
1x Maxtor Diamond Max 300GB SATA HDD
1x WD MyBook 500GB (originally an external drive)
2x DVD/RW drives (one not writing or reading properly)
1x Wireless PCI Adapter card
1x Firewire card
500W ATX PSU (Ednet, Germany) Output +3.3V@28A; +5V@30A; -5V@0.3A; +12V@34A; -12V@0.8A; +5VSB@3.0A
My Problem:
Attempted to power the machine on this morning. All fans running (MB southbridge fan, CPU fan, PSU fans, case fans, GPU fan etc.). All lights on (including yellowish-green MB light + dvd drives lights). I get a new buzzing sound coming from the PSU. Machine would not give me single post beep. Tried again numerous times. Still not post and screen remains blank.
Action Taken:
1. Removed 500GB WD HD that I recently took out of external housing (because of defect) and had running in the machine for the last two weeks --as above and still not post
2. Removed ALL RAM + Graphics card and pushed power -- as above and no beeps heard
3. Inserted one stick of RAM (still without Graphic card) -- as above and no beeps heard
Recent problems with machine:
1.Fan on the A8N-E Southbridge has been giving me problems for the last year or so. It will occasionally whine loudly or fail to spin up to max rpm on cold boot. I have received the double beeps regarding its fan speed on boot up several times in the past few months but when I restart the fan will eventually spin up. I have monitored the chipfan speed and temp for the last year. It should be running at 6.0rpm but lately has been down to 4.0-5.0 although MB temps never go over 40 Celsius.
2. My WD Mybook 500GB external HD bit the dust two weeks ago and in an attempt to recover the data, I pulled the drive out of its casing and connected it to my SATA cables in my machine. I was so happy with the result that I kept in permanently. It has been running hot -- at least 10 degrees hotter than my main HD (Maxtor Diamond Max). I have seen it running at around 55-56 Celsius often.
3. RAM was not seated properly or got loose (last month) so machine would not boot. I changed slots and seated RAM properly and everything was back in action and worked perfectly.
Thoughts:
I guess the problem can be one or more of the following:
1. PSU shot (remember the buzzing sound)
2. MoBo shot
3. CPU shot
Can anyone suggest a way to determine which one of these components is causing my problem or a possible solution or even something I haven't tried yet. Thank you for your support and time in advance.....

for the fan on the southbridge you can remove the sticker half way and put a couple drops of oil in there and that should take care of the whiney noise.
The psu is making noises and your having these problems then just try using another psu or take your psu out and bring to your local shop and see if they have a tester to test it.
with your hard drive running hot, check your case ventilation: do you have a intake case fan in the front? does it need cleaning? can you rearrange cables to allow more airflow?
The Ram on some computers vibrates out of their slots and needs to be reseated. it happens a lot on wood floors.

PSU - I would swap that out first. Good chance its that. I never heard of Ednet, so dont know reliability.

Thanks for the advice! I will be taking the PSU to my local shop to test it. I am hoping this is the problem because it is the easiest to remedy. I will keep you posted.
-- What brand of PSU would you all recommend (and I am not made of money)?

I had a very similar problem, turned out it was the case short circuiting the motherboard (I had this case for two years, but it suddenly happened). What I suggest, before taking drastic measures, just unscrew the motherboard from the case and put it down on a newspaper (everything else still attached to it), and try turning the PC on. I ran my PC on a newspaper for a week until I found a case I liked.

i would go with iNatan's advice, a buzzing sound like that from a psu would normally indicate something is shorting the psu. if not a short on the case etc it maybe a peripheral. try out of case with absolute minimal parts connected (m/b, cpu, ram, gfx - no drives or extra fans), if no go then borrow a psu and try.
if you take ur psu into a shop for testing they'll probably tell you its dead and upsell you a much bigger psu whatever the result of testing

My PSU Exploded!!
...I was about to try running the MoBo out of the case so I removed all of my cards including the graphics card - unplugged both HD's, DVD R/W's and stood there and stared at it for a while before deciding to push the power button. There was a huge POP! All the lights in my front room went out as a blue spark flew out the back of the PSU. I stood there stunned in total darkness as the dust settled and the smell of burning electrics filled the room. I guess I know now what the problem was. Gladly most of my components were unplugged at the time but what about my CPU, RAM and MoBo? Any advice at this stage would be more than appreciated...

find out how many watts it had and add a 100 or so and go buy another one or start an RMA if it's under warranty, plug everything back in and turn it on.

wtf kind of PSU was this? I never had that before. When I had PSU's die all I heard was a buzzing sound like you mentioned. Don't buy generic or non name brand PSU's! EVER. Even budget builds. I'm interested if that PSU didn't surge throughout the mobo and kill everything connected. Let me know.

UPDATE:
Just received a Be Quiet! Straight Power BQT E6-700W 80plus in the mail this afternoon. Mounted it in the box, connected everything and powered it up. Everything working like clockwork. No damage to MoBo or CPU. The nightmare is over!
