x200 (7454-2qu)
vista business 32
Upgraded with 2gb I ordered from Lenovo. (P/N: 43R1988)

It looks like moving off 2.02 fixed it for some people. Anyone have problems with this?

I found this post but wasn't sure about downloading the Japanese 2.04 bios:

Anything I should worry about trying to use a foreign bios update?

And some people said downgrading to 1.10 bios would fix the issue:

Is there anything special about flashing a bios to an earlier version? Or will it just overwrite? I've only upgraded, never downgraded.

Thanks.

Are you able to boot up in windows at all? Are you able to run some Linux Live CD? Any beeps after powering on the machine?

Run a few passes of memtest86+ to test the memory. What RAM configuration does memtest report then?

I get the lenovo screen and it starts to load windows but then bsod after a few seconds. Safe mode, last known good config both = BSOD too.

I'm running memtest right now. We'll see what it shows tomorrow.

No errors detected with Memtest86+.

I'm able to boot both centos and knoppix live cd's just fine so maybe it's something with windows and not my bios. I tried to repair the windows install but it didn't help. I might just boot R&R and do a factory default since I haven't put much on the system yet. I'm not sure what else to try.

To me it sounds like a windows problem, but I also don´t exclude some BIOS problem. What is the BIOS version? BTW, what are the RAM specs reported by memtest (all the same for both modules)? I remember reading something about Vista 32-bit BSODing with 4 GBs of RAM, but that story was even before SP1... I´ll try to find this piece of information again. Some folks also suggest that the problem may be caused by a bad driver, but I don´t think this is the case because the same happens when booting into Safe Mode (with as much drivers disabled as possible).
