Help Loud CPU Fan No Boot

tbfoster1 · 05-11-2008, 07:23 PM

I could really use some help here. This post might be kind of lengthy but I want to make sure I cover everything

First: The system I am working with:

HP Pavilion Media Center (m7580n)
AMD Athlon 64 x2 Dual-core processor 4400
2G Ram
NVIDIA GeForce 7300 LE Graphics Card
320G Hard Drive

My sister called me and said she has no video output on the monitor. When I arrived I realized the CPU fan was running loud and I noticed the computer wasn't booting so I started rooting around inside.

Here is what I did
I blew out all the dust inside of the computer
I removed and replaced the CMOS battery
I reseated all the cards
I tried booting with each of the RAM sticks and then with no RAM.
Finally I removed the SATA Cable from the motherboard and reseated it. It started working. It worked for a couple of weeks and then the same problem came back.

This time I tried reseating the SATA Cable again, then moved the cable to another SATA Connection on the MB (there is 4 SATA on the MB but only 1 is used)

I Tried unplugging the power and IDE connection from the DVD/CD

I then took an old hard drive and used the (Master) Side of the IDE that is normally plugged into the DVD/CD. So the SATA drive was not in use at all

And I tried Reseating the CPU Fan power connection to the motherboard.
Nothing is working and I have a loud CPU FAN and no hard drive activity. Does anyone have any suggestions. I would be much appreciative.

Thank You

No, it deosn't look like it is POSTing at all. I can't get into safe mode or BIOS. It says no input on the screen, there is no hard drive activity the only thing that looks like its running is the fan and that is running hard and loud.

Please try to Clear the CMOS again.

I tried that again like you said but it didn't work

Try the following:

- Clear CMOS
- remove all add-on cards but the video card (if it is not on-board)
- remove all IDE/SATA/FDD cables FROM the motherboard (not from the device)

Now what you should have still put together is: mobo, CPU + heatsink, RAM, video card (if not on-board), monitor, keyboard.
If you still have some other devices connected through USB or firewire, please disconnect the corresponding cables from the computer.

Now, power-on the computer.
See if it works.
