Help with rebooting and error message

A system I built for my parents recently started acting up- here are the specs and a summary of the problems:

Biostar T Force 6100 socket 754
Sempron 2800+
2 x 512 Mushkin value ram
WD Sata HDD, 80gb
Lite-On DVD-rom
Leadtek 6200TC PCIe
Audigy 1
XP Pro SP2
Enhance 5160 500W

A breakdown of the problems:

1. System first put together ~6 months ago; ran all the normal stress tests (Prime 95, RTHDRIBL, etc) and with no problems. No OCing.

2. Problems first began about two months after use- parents complained about random shutdowns during normal use, and this occurred mostly during the first few seconds to minutes of powering on.

3. My next trip home, I re-ran a bunch of tests, and everything looked OK. Ran virus/adware scans, with no problems. I had all users on limited accounts, was running FF only, with all updates. AV and firewall in background with auto-updates.

4. Three months later, I learn that the system now will not even boot into Windows. I try to troubleshoot over the phone, and learn that the system enters into an endless rebooting cycle once it hits the Windows XP loading screen. Safe mode does not work, and trying to boot from the XP CD does not work.

5. I order a new PSU (the Enhance) and have my father install it. The installation goes without a hitch, but the same problem persists. I guide him through upping the CPU voltage to 1.425 and RAM to 2.7, but nothing helps.

6. I have my father press F8 and try for safe mode again, with no luck; last known good config also leads to reboot, as does safe mode with command prompt. When I have him disable the "reboot automatically" function, he gets this error code:

Stop;_C0000221{bad image checksum}
Image_urlmon.dll is possibly corrupt

The header checksum does not match the computer checksum


I have had him strip the system to bare essentials, booting with one stick of RAM and then the other, and trying different SATA ports, all to no avail. I am quite certain it is now a mobo or HDD issue, but cannot rule out a software problem. The inability to boot succesfully from an optical drive really makes things difficult. I am not sure if I should have a new HDD shipped home, or if I should order them a new mobo.

Any help would be appreciated.
