If your getting text on the screen i would say its a hard drive issue (guess ) . Does it give you any series of beeps ?  Ive got a couple of 7200rpm Ide drives layin around if ya need one , ive also got 256 of ddr 2100, and 2700  , 512 of pc 133 , and a generic 400w psu  if needed. Ive also got a FX 5200 128 card , all  pulled out of a scrap machines , but tested .    38
