Here are the stop code errors off Microsoft’s site
Stop 0x000000D1 or DRIVER_IRQL_NOT_LESS_OR_EQUAL
The Stop 0xD1 message indicates that the system attempted to access pageable memory using a kernel process IRQL that was too high. Drivers that have used improper addresses typically cause this error.
Interpreting the Message
This Stop message has four parameters:
1. Memory referenced.
2. IRQL at time of reference.
3. Type of access (0x00000000 = read operation, 0x00000001 = write operation).
4. Address that referenced memory.
Resolving the Problem
For additional troubleshooting suggestions that apply to all Stop errors, see "Stop Message Checklist" later in this appendix.
· Stop 0xD1 messages can occur after installing faulty drivers or system services. If a driver is listed by name, disable, remove, or roll back that driver to confirm that this resolves the error. If so, contact the manufacturer about a possible update. Using updated software is especially important for backup programs, multimedia applications, antivirus scanners, DVD playback, and CD mastering tools.
For more information about Stop 0xD1 messages, see the Microsoft Knowledge Base link on the Web Resources page at

"STOP 0x0000008e" Error Message During Windows XP Setup
The information in this article applies to:
· Microsoft Windows XP Professional
· Microsoft Windows XP Home Edition
This article was previously published under Q315335
SYMPTOMS
When you install Microsoft Windows XP, you may receive a STOP error message similar to one of the following during Setup:
STOP 0x0000008e
or
STOP 0x00000050 PAGE_FAULT_IN_NON_PAGED_AREA
Additionally, if you troubleshoot by removing all unnecessary hardware devices that are installed on the computer, and then running Setup, you may receive an error message similar to the following:
Setup cannot copy the file Setupdd.sys.
CAUSE
This behavior can occur if one of the following conditions is true:
· One or more of the random access memory (RAM) modules that are installed on your computer are faulty.
· The RAM configuration is incompatible with Windows XP.
RESOLUTION
To troubleshoot and resolve this behavior, follow these steps:
1. Remove some of the memory modules that are installed on the computer. Leave at least the amount of RAM required for the computer to start and run Windows XP.
The recommended amount of RAM to run Windows XP is 128 megabytes (MB). The minimum is 64 MB and the maximum is 4 gigabytes.
For example, if two 256-MB memory modules are installed on your computer, remove one of the memory modules.
2. Restart the computer, and then run Setup.
3. If you again receive the error message that is described in the "Symptoms" section of this article, proceed to step 4.
4. Remove a different memory module, or install the RAM in a different memory slot.
5. Restart your computer, and then rerun Setup.
You may need to restart your computer several times in order to identify the specific memory modules that are not working correctly.
MORE INFORMATION
For information about how to add and remove RAM, contact the manufacturer of the computer or see the documentation that is included with your computer.

I think the fastest way to resolve this would be to Download and run memtest like Bloom said. If its not your ram, (and your temps are ok) leave a good stick of ram in, download Sandra from here
http://www.sisoftware.co.uk/?location=update I would then remove everything but the video card run the Sandra burn in wizard for 10 to 15 min if it makes it with no lock up then start putting stuff back in one at a time make sure you run Sandra after each item goes in.
Is there any chance you could have missed a standoff when you installed the motherboard a shorted motherboard can cause this also.
