Hi first off ill give you my pc spec Amd Sempron 3000+ about 1.8ghz. 1gig ram 80gb harddrive sata and a gigabyte 6100 m2ma motherboard.

When i got this pc it needed a new harddrive and new ram i brought the ram 1gig of ddr2 and i brought a brand new hdd started to formatt it and then proceeded to install windows xp after formatting It would say please wait while it installs the windows files and stuff but kept freezing at 15% so i couldnt load xp on it so later i went into the bios and for some stupid reason i set it to optimised defaults but still kept freezing then i thought id try fail safe defaults and now when i turn it on it just comes up a black screen with a flashing cursor at the top even if i go into the bios and set my dvd rom drive for first boot device it makes no difference and wont load up the os just a black screen dont know what to try now i was wondering if anyone had any ideas of how to fix this
