hi there.. if u saw my thread @ video section, then i 'solved' the prob. the prob is that the IDE CDR/RW (NEC NR9100+) has a conflict or prob with the motherboard and/or video card. it's not both cds and when i disable it the pc works fine. k.. this is the prob - after i shutdown my pc and power it on, the bios loads (i have a dell motheroard intel based) the light on both cds starts to blink but instead of disappearing (in a normal situation or after a reboot / reset) the light stays on (not blinking) on the CDR/RW. as if it's not responding. power is getting to it (i can see the light) but when i even try to eject the cd tray it doesn't respond. if i do the same thing on the CD-Rom (Samsung SC-148) the tray ejects and also there's no blinking light. i'd like to know if there's anything i can do about it, do i need to change firmware, change cables / jumpers (i already did - jumper is set on both as 'CS - cable select'), change the cdr/rw... i contacted dell about my original prob and they didn't tell me anything new that i didn' t know.. so.. i'm turning to the 'experts' on this board... help me!
