battery should be good, but now the thing is you need to set your cdrom to boot 1st.
im not sure how many pieces of ram u have, if you have 2, why not take out 1, then it will actually stall at the startup
or turn of your dekstop, then hold down f2 then only turn it back on
cdrom i have it is in ruunngin and ok but bout ram i have 2 piece each 512mb
ill check it separetly
