Urgent help needed for branded used PC

[Diya]

i got my branded used pc in this specification:

Intel (R) Pentium 4 CPU 2.40 GHZ
2.39 GHZ, 512 MB of Ram
IBM Data Fax Modem
Sony DVD-ROM DDU 220E
Level 2 cache:512kb integrated
BIOS version: A05
Dell precision work station 340 series
Hard disk: 77gb
Motherboard: I DON'T KNOW

1- now the matter is, in branded used pc its a new win installation and it loads within sec's

but in old pc (*unbranded) which speed is 550mhz, intel P3, 128MB of Ram takes a lot of time in loading due to files, when i install new win in old pc it also load faster but not like DELL (new one).

2- What if i will migrate my 3-4 lack files in dell (branded used pc) will it also load faster?

3- And what u will say about my pc speed?

4- What if i will face any hardware failure problem in future, like losing power supply. (can i easily upgrade power supply and other hardware)

5- And how to check how much processor and ram has been used?

I don't understand. what are your "3-4 lack files"? Maybe also, when you clarify that you can be more clear the your questions on pc speeed and whose pc speed you ask aboiut.

5- And how to check how much processor and ram has been used?

How much has been used??? Don't follow just what yoiu ask here either. Sorry

All your files will load faster yes, however I advise getting another 512MB of RAM to make the total 1GB. It will make performance much smoother.

Aside from that, everything else looks ok. You're good to go.
