But the story sounds like a broken machine. Your questions sound as if you want a course in computer repair or for a STEP BY STEP HOW DO I REPAIR MY BUSTED PC?
There are plenty of web sites about PC repair but in your case it sounds like the basic IDE RULES are something you should research. All this is on the web but some dislike reading and learning then DEMAND others re-write the answers or content. Please use the ready and easy to find content or you'll end up at a repair counter or buying a new machine.
In fact, why not look for another machine? That class machine is often found for free on the free area of Craig's list or FREECYCLE.
-> If I were to guess, you didn't follow the rules on how to configure IDE drives, cables, jumpers and may have a dead hard drive.
I'm trying to run my recently re-installed windows xp pro o/s home desktop pc. It's a brand called Linspire model GQ3151, and there is no official support for that particular system cuz' the manufacturer company went bust years ago.
Every-time I try to boot-up my system, I get the following error message as follows."Verifying DMI Pool Data. Boot from CD. Nvidia Boot Agent. PXE-E61: Media test failure, check cable. PXE-MOF: Existing Nvidia Boot agent. Disk boot failure, please insert system disk & press enter. I got this error error message, after I had swapped dvd players & inserted a new pci graphics card. So far, I've tried several suggested possible solutions, with no success, as follows. I made sure that the Serial ATA hard drive was properly tightly connected, which it was. I went to the bios & cmos menu, reverted to optimized defaults. I inserted a windows xp installation disk, and it didn't even detect that my ATA H.D. was connected at all, which I definitely knew that it was. I tried unplugging & reinserting the cmos battery & jumper settings. I unplugged all the cables from the pc for a while, & replugged them later to power-up. None of the actions I took to fix my system, did absolutely not work. So can anyone suggest a solution(s)? Can anyone also refer me to a good forum that post help for computer questions like mine?
