Phoenix BIOS problem

[syrdax]

Hi.
I have a Presario 2505EA, P4 2.4 GHz, 512RAM, on board Radeon IGP 345M; the thing is that few days back I had just one stick of 256RAM and as I wanted to play some games I bought another stick, so I did also a BIOS update search and I ended up in the Compaq website where I found for this particular computer a Winflash utility that updates to KF.F.14 (Phoenix BIOS), the thing is that when I did all the stuff, computer ran slower yet, and everytime I restart Windows, the computer turns off for about 1 second before start to run again (when I restarted before, the process is without that 1 second off, I mean, everything is working, disk, etc, but now, all stops for 1 second); onther thing is that whenever the heat activates the fan, everyhting slows down, even if I am playing Freecel. I days after I found newer versions, KF.F.23 for this particular model but didn't worked, none of them, even 15 to 24; it says that the BIOS is not for this computer. I asked to the help system in Compaq site and they put me to chat with a guy or bot that didn't help me much.
So questions are: is there a way to get back to the older BIOS version?
What happended to fans that slows down the system when starts to run faster?
Thanks for any help.
Best regards

Not sure where you found that utility, but Compaq lists the KH.F.13 bios as being current. You could try downloading that and installing from dos

I think this http://h10025.www1.hp.com/ewfrf/wc/s...dlc=en&lang=en

is the most current BIOS available. Download the ROMPaq and follow the instructions on web page. Every now and again a BIOS update goes wrong, but you can often recover from it.
