Before I start I want to thank everybody who will try to help me on this thread, I wont be able to reply until tomorrow (I'm using my neighborhood's computer)... Making a long story short, here's my question: is there any other possible problem (other than memory problem) when you turn the computer on and you see the message ""no video display" (or something like this) on the screen? I already "swap" memory, monitor, video card and hard drive with my neighbored computer and on his computer works fine, but mine I don't see it anything other than this message... Here's my specs: Mobo INTEL D875PBZLK Pentium 4 3.0 Ati Radeon 9700PRO 2 sicks of Corsair MB (each) ddr cmx512 3200 MHz HD Seagate120GB Once again Thanks!!!! Have a great week all!!!!
