I bought a hp fore some years ago. Befor i know any about computing.
stil using this hp. and learn everything i now on it.
So when i discoverd that it was amd athlon. and that the mobo used normal memory. (SDRAM)
I thougt i had tumbeled over a hp who was easy too upgrade.
I started with memory. replaced to two 512 mb.
and it work.
pc speeded up good.
after a few months i kinda wanted more speed. so i was looking for either a new cpu or grafic.
Found out that the mobo cane only handel one size cpu. and that is the original size of 1.3 ghz.
So i started looking for a grafic card. Then i found out that the tiny psu already having power troubel. and can't handel even a slightly better grafic car
So then i start looking for a new psu. But then i discovered that the psu place in the case. That is spezial. so a std psu wil not ever fitt.
I also discovered why i had some cooling problems.
Cos ther i sone fan in the back blowing in the case. in a "tube" who direkts the air to the cpu. thats it. no cooling for hd's. Ands since ive upgraded to an xtra 250 Gb. it generated alot of heat.
So to make it work. i had to remove the side panel. Remove the tube. then having a tabel fan next to the case bloving air in.
then i had to put the new hd out of the hd holders.and stand it up right in front of this tabel fan.
Temperture is now good. but it looks like "Reodor felgen" built the pc.
