That computer is a bit old, I bought it 2 years ago but here are the specs from what I can remember.
Athlon XP 2600 Processor
512 MB RAM (added 256 MB ram , switched it to see which one works better)
64 MB nvidia Graphics card
40 GB Harddrive (got a 160GB one , had the same problem so returned it)
16x DVD rom
42x CD/RW
56K Modem
im not sure how much power supply.. but from what I can guess.. 400 or someting.. dont count on that.
Everythign else is on board on a nvidia motherboard.(sound, ethernet)
It was interesting though, I was installing XP on the new harddrive, and before the Windows XP Setup started, the comp showed me the BSoD and it said CDFS error. I went into the BIOS and i disabled the cache, and it was working, even though it was terribly slowwww.. setup was taking double or tripple the itme it would take so when it resratred during the middle of the setup, I changed the cache back to enable, and the setup was not going through, after liek a certain amount of time, maybe like 5 minutes, the computer kept restarting. I never tried to turn it back to disabled and see if that worked because im not a patient guy!
SO if you guys have any ideas... let me know..
