My computer locks up constantly, and sometimes on boot I get the folder with a question mark. I have trie a different hard drive and it does the same thing. As I would like to avoid purchasing a whole replacement logic board, does anyone have any other suggestions?
Is this a good question?

Of course when you get the question mark it means your unit can't find an operating system. If you've replaced the drive, even if you haven't, I would reformat the drive and use the option "write zeros". This will map out any bad blocks on the hard drive. A bad block will cause your system not to work sometimes when part of the system gets written to it. As a matter of course now, I zero out every hard drive I get, especially brand new ones. These hard drives are made as cheaply as possible and quality controls allows certain percentages of drives to be defective. So do your own quality control and you won't have to worry about this potentially devastating problem.

The thing is, I took a known working drive with OS X already installed and I am getting the exact same results. It boots most of the time with random question mark folder errors. But when I boot into OS X the computer locks up every few minutes and I get I/O errors in the Console. I have tried a total of 3 known working drives all with the same results.
If you're lucky it may be the hard drive cable, check your logic board connections first. To test start up from your system installation disk holding down the "D" key and run diagnostics.

I agree with mayer, try another known working hard drive cable.
+ Very sound advice all the way around.

You do if the cable is the cause of the problem if it's the HD itself or the connector at the board, no you wont.
I did order a new sata cable from ifixit and it fixed my problem.
