Compatability issues

You should be able to pick an adaptor up at a local computer store for about $8 - $15.
If you have made upgrades, make sure that 250w PSU can handle it.

The manual (which I just read. ) says that i can use the 20 pin. Should work fine. I think it may be the power requirements, but im still reading. If anyone learns anything, please say so.

The board is A74MX Foxconn. Additionally, I had the same hard drive in a different computer, and windows is still on it. do I need to format and reinstall to get things working? just brainstorming here, as i have no idea what im doing.

The processor is AMD Athlon X2 64 btw

been reading about BSOD, and my error is:

INACCESSIBLE_BOOT_DEVICE 0x0000007B

The hard drive worked fine before the new mobo and processor. Unfortunately, I cant use the disk drive on that computer, so I cant boot from the windows disk to re-install or run the chkdsk thing. Any ideas?

Are you saying that the DVD drive on the computer with the Foxcom MB and 64 x 2 CPU doesn't work?

At only 250w, your PSU is probably way too small for your new setup. Does the BIOS "see" your hard drive?

Before Windows even begins to start you enter the computer's BIOS or Setup screen. Typically, several seconds after you hit power on, your PC will emit a single beep; at that point, you press a key to enter setup - usually the DELete or F2 keys, depending on motherboard manufacturer.

Once in the BIOS (or "Setup" screen), you should be able to find a display indicating the amount of installed memory as well as all drives (floppy/CD/DVD/HDD).

Don't go mucking about in there, by the way. After you have seen what you want be sure to do an "Exit without saving changes"

Problem solved. Motherboard only has one IDE slot, and I need to reinstall windows. Ill have to get a SATA HD and then plug the CD drive in the IDE slot and use that to reinstall windows. Thanks for trying to help me guys, sorry I didnt give you much to work with.

Yea, I would have tried that, but the board has 4 SATA plugs, so I figured I better just get what the board wants instead of fighting to use old stuff. In addition, after I reinstalled Windows, the computer worked fine, but the CD Drive wouldnt work. I could explore it and look at the files, but I couldnt open anything. Took the computer to my gf's Uncle (Computer Repair Technician) and even he had no idea. We just replaced the IDE cable and CD drive and it worked. But I dont think the old drive was bad, or how could I have used it to install Windows?
