I just finished building a new pc from parts bought on ebay. I have a brand new case with 450 watt powersupply. A mobostar -asrock- x533 motherboard. My one year old nvidia geforce fx 5500 agp video card. and planing on using the onboard sound and ethernet connection for my cable internet. the mother board accepts ddr266 ram and or pc 133 ram. I have 2 pc 133 256 mb ram dimms on the board. A used pentium 4 2.6 mghz 512 mem installed and a new ultra fire pentium 4 cpu cooler. an old western digital 30 gig hard drive. windows xp home. I couldnt get it to turn on and then i changed the jumper on mobo from 480 some thing hrz to 533 hrz fsb. it starts up and runs the cp self test and shows data such as processor, memory, hard drives, etc... Then it shows: searching for cd rom boot record... none, searching for floppy boot record... none, Searching for ide-0 boot record... ok, and nothing happens after that. i put the hard drive in old pc and it boots up no problems. What should i do?

Looks like there might be a probs with your connections with hard drive, as it is having trouble in finding the boot record but the hard drive loads fine on other PC. Try changing the IDE cables and see if that makes any difference.
