ok, i know what your thinking... search the forums!

I did... a LOT....

Ok, here's the story and history and a little background:

I am a little tech... i say little in terms of i know most of the terms and some fun things with computers. I help others and fix minor problems for FRIENDS, co-workers and bosses. That said, if you have any advice, there is no need to bother with "lamens terms"..lol

Now, i recently bought a used computer from a friend. When i bought it she mentioned that it needed a new CPU fan. I asked how do you know (she is not very computer litterate and needed to know more details incase there is something other than that). She said that the computer told her so. Well, you can't get much more exact than that.

After playing around with it and trouble shooting some minor problems.... no video, POST codes, and boot up and shut down in 5 second intervals, traveling to more than one store, i ended up going and buying a new CPU heat sink w/ fan.

Now this i figured should solve the problem. No, instead it SHOWED me the problem. The computer now boots, AND shows video, but then about 10 sec into, after the first screen of the manufacture (compaq) with the help text at the bottom of the screen telling of the key inputs (ex: F1-setup), the screen changes to a simple black screen with text telling me that the system fan failed and will shut down in a few seconds. Please asses the problem immediatly.

I could only think of one thing. There are only 2 fans in the computer, the CPU, and the PSU. So, i took a different power supply from another computer lying around, and tried it. The PSU though did not have all of the required plugs, there was the standard 20 pin, but it needed an additional 4 pin plug to be put into the MOBO at a different location. I tied to start the computer anyways.....
I unpluged all unwanted items. So there was only the MOBO, the RAM, the CPU (w/ fan), and the PSU. (haha.. so many abbrev.)

This time, the computer turned on, fans spun, DID NOT TURN OFF.... but no video. OK, so i pluged to original back in and looked to see if the PSU fan was spinning... yes, it was.

Now being frusturated, i went to the store and bought a 400 wat power supply... easily enough to replace the 250 wat original.

No avail.
Same screen appears and shuts down...... and yes i tried to go into CMOS and bypass/reset this fan test. It does not allow me to. Still the screen appears.

Already i have spent half as much money trying to fix it as i paid for the whole computer. If there is anything that i can do to get it working, it waould be greatly appreciated!!!


Model ............ Compq Presario SR1303WM
CPU .............. AMD Sempron 3000+ 2.0 GHz
Motherboard .. Asus A7V8X-LA
RAM .............. 512 MB (1x 184 pin, DDR SDRAM, PC2700)

If there is any other information needed please ask. Thank you in advanced. Reset the BIOS to it's default settings.

It may be monitoring a fan that isn't there. Or you connected the CPU or PSU fan(Monitor) to the wrong connector.And did the new PSU have the additional 4 prong plug ? ? This may be important...

I can't get into BIOS, when i try to press the button for setup (or any button for that matter), it still goes to the same screen. I thought the same thing, but i just cant get into it.

Yes, the new PSU has the correct conectors

My mother board is pretty simple. The CPU fan can only go into one plug... labled 'CPU fan', and there is only one more plug that the PSU can additionaly plug into. lol, can asure you that it is all done correctly, also there is no monitoring devices in addition to the MOBO's. (ie: a sepperate temperature guage)Quote
