Computer Wont Reboot Unless I Switch RAM Slots?

[Tsunami982]

My HTPC blue screens when loading Windows (halfway through the startup animation) unless I turn it off and move the ram into a different slot (mobo has 4 slots and it doesnt seem to matter which slot its in as long as its been moved). The ram was at stock settings but I've tried changing the voltage with no change. I also tried reinstalling the OS (XP Pro, Vista 32+64, 7 RC7100 32+64) but it blue screens while the installation program is loading. Safe mode also doesn't load. I've tried different sticks of ram of differing size (1-4gb) and speed (533-1066) with no change.

Its really really annoying to have to move the RAM around every time I need to reboot so if someone can help or have any suggestions I would REALLY REALLY appreciate it. Money is tight and I am hoping nothing needs to be replaced.

Specs (all non-essential components have been removed already with no change):

AMD 2300BE
Abit AN-M2 Mobo
4gb Crucial Value DDR2 800 (tried several other brands/speeds/sizes as well)
1.5TB Seagate HDD (tried using 1TB Samsung and Seagate as well)
Antec 430w PSU (came with Antec Veris Fusion 2.0 HTPC case)

Have you tested each stick to make sure one isntbad?

I have tried 10 sticks of RAM (2 of which were brand new and previously unopened) most from other working computers. The RAM originally in the HTPC works fine in other computers. I thought it was the RAM at first too. Increased and decreased voltage/timings, more around to different slots... I'm all out of ideas

Beyond just swapping memory modules, have you tried running memtest+ ?

Nope... but I will now. I just assumed that going through so many different sticks that are confirmed working would eliminate the chance that its a defective stick problem.

Yesterday I also swapped out the power supply twice (one brand new and one working pull)... no help

Thanks again for the suggestions... they are truly appreciated.

Does any of the memory you're trying appear on THIS LIST?

Didn't think of that... but I just checked right now and 4 of the sticks I tried are on the list

Someone suggested cooling the RAM... I pointed a 120mm fan at full blast right on top of the RAM... still no go
