Here's a fun one....looking for confirmation. I have a Pavilion 750C. I purchased some memory (which is what I suspect, but read on) - PC2100, 256K from CompUSA.
I installed the stick (the PC had no memory it in when I got it) and was able to get the system operational, throwing in my own hard drive, floppy and cr rom.
I formatted the drive, loaded W98SE (what I had available) and found all the drivers needed...all was working great. I only needed to get the driver for the modem, which I don't even use...
I unplugged pc since I had it open on the floor....
So the next morning I plug it in and power it up - get NOTHING!! No bios, no video, no power light on the front of the PC...but there was 5V and 12V on the hd connectors...also the hard drive light was on solid.
I started troubleshooting and here's what I found:
I pulled out the HD and CD ROM and Floppy, so nothing was connected. Same thing.
There is a small led on the back of the power supply. It is lit green.
There is an LED on the main board that lights when the AC cord is plugged in, it is lit OK.
Here's the trick but I can't figure out why!:
The power supply fan. When I first start the PC, the fan turns fine. After about 2-3 seconds, the fan stops. I noticed a plug on the ps that goes to a connector on the main board, called "psfan" (but it is not actually fan power so I am thinking it must be a sensor or something...).
If I unplug that connector, the fan spins fine...even after the 3 seconds or so...but I still get no video, bios, etc...
I don't have a speaker connected, so I am thinking to get one connected.
I am "hoping" it's RAM but don't feel confident. Anyone have experience with the Pavilion 750C and/or the ASUS P4B266-LA motherboard?
