I just upgraded my hp dv6426us from 1gb of ram (512x2) to 4 gb (2x2). I have a vista 32 bit and xp 32 bit dual boot os configuration.
Now when I boot up xp gives me a bsod right after showing the spalsh screen. It does this in safe mode too. However, Vista works fine. The bios shows 4096mb of ram. Vista System information shows: Installed physical memory (RAM): 4.00 GB Total physical memory: 2.99 GB
I would like to be able to use xp with 4 gb of ram, or at least the 3 gb it cuts it down to (if it does.) I would not like to go back to using 1 gb. Any suggestions? Thanks!
EDIT: the bsod shows:
A problem has been detected and windows has been shut down to prevent damage to your computer. If this is the first time you've seen this stop error screen, restart your computer. If this screen appears again, follow these steps:
Check for viruses on your computer. Remove any newly installed hard drives or hard drive contollers. Check your hard drive to make sure it is proberley configured and terminated. Run CHKDSK /F to check for hard drive corruption, and then restart your computer
Technical information:

also, memtest86 results are no errors

do a boot logging with the XP, then hop from the vista and read where the bootlog ends. It can help to clear the prefetch folder for boot logging. I think i have seen this with a video driver, if only i could remember, it might be a thing to disable (run in copmpatability) first to test, because of the "way" they use that memory spaces. Safe isnt very safe (even back in xo) many of the high end drivers are set to run as safe. also, You should still do a memtest86 with a boot disk, but from what your saying that isnt As Nessisary. It is likely to be a driver item, – Psycogeek – 2014-02-08T10:21:23.020
Ok, I will learn about bootlogging and attempt to do one right now! Thanks for the quick answer – Blaine – 2014-02-08T10:30:38.447
Chances are good this is fixable. If you can you want to bootlog the old way (where it worked) then bootlog with it failing, it will save a lot of time seeing what is the next item in the bootlog , where it faild. – Psycogeek – 2014-02-08T10:30:59.960
ok... so you mean do a bootlog first with 1 gb of ram, then do one with the 4 gb? – Blaine – 2014-02-08T10:32:43.940
That is correct. When it fails, the bootlog may or may not show the item is was about to load at that time. The working bootlog would show everything. – Psycogeek – 2014-02-08T10:35:30.530
ok, just enabled boot logging in xp. it bsod and restarted. Now i am booting into vista to check the log. – Blaine – 2014-02-08T10:41:10.020
ok, how do i read "bootstat.dat"? I can not open it with notepad – Blaine – 2014-02-08T11:06:29.993
BootLog.txt is what your looking for. – Psycogeek – 2014-02-08T11:31:35.863
i see no file called bootlog.txt – Blaine – 2014-02-08T11:36:31.783
My problem looks like it cannot write the file because it crashes before any drivers get loaded – Blaine – 2014-02-08T11:41:40.410
That could very well be. Debugging mode would step by step through the failing process, it would give you a better idea of when it bails out. – Psycogeek – 2014-02-08T11:48:32.360
Debugging mode gives a bsod too :( – Blaine – 2014-02-08T11:55:01.330
It will, it isnt "safe" it steps slower. Did it show you any text that might be usefull in diagnosing the issue? (it would rarely show the thing causing the fail) Could you put the Error and the number of the BSOD into the question. – Psycogeek – 2014-02-08T12:01:31.840
I am gone now. Last thoughts. When the system is operational (1gig mem) "system configuration" Msconfig.exe could also assist in reducing the boot stuff. In Boot tab "[X} Base video" , In service tab, Hide all microsoft then disable all 3rd party, in Startup tab disable all. In the "device manager", disable video driver (temporarily) also other large 3rd party driver items you might suspect. – Psycogeek – 2014-02-08T12:32:47.200
I am pretty sure that the problem is not with boot items. (it is an almost fresh os with no recently installed items.) bsod is now in the question – Blaine – 2014-02-08T23:34:05.310
Correct again, that error is when the hard drive is an issue, Which in the case could be caused by a real memory problem, also could have already been caused, meaning the disk may need to be chacked before it is assumed that it is fully bootable. Memtest, then check the disk. – Psycogeek – 2014-02-09T01:43:26.127
sorry, how do i do memtest? can I do it from a 3rd party app in vista? – Blaine – 2014-02-09T02:00:16.517
nevermind. figured out how to run memtest. will try now – Blaine – 2014-02-09T02:15:00.213
sorry that took me so long. just ran memtest86 and the results are "no errors" Any idea what could be causing the blue screen? does xp just not like 4gb of ram? should I run the computer with 1x2gb and 1x512mb? – Blaine – 2014-02-10T10:29:44.050
32bit XP is very happy with what is left of 4gigs the addition of the stop error code improves the question by a lot. – Psycogeek – 2014-02-10T12:20:44.140
but xp does not look happy. It should be, but it is still giving me a stop error. – Blaine – 2014-02-10T12:33:04.860

Can you post here the results of BCDEdit from vista? If I recall correctly you can limit the the memory your OS can see through there. 2. Try deleting pasgefile.sys from the XP partition, and try booting - it's a long shot but doesn't hurt to try. 3. Try booting with one 2GB memory stick, and tell us how it goes. – EliadTech – 2014-02-10T14:29:44.950
2Could you check if SATA mode in BIOS is set to AHCI. To boot xp it should be set to ATA. – arundevma – 2014-02-12T10:24:00.327
if you take out the recently upgraded memory sticks and put back the old replaced memory sticks, do you still receive the stop 7b bsod? – Costin Gușă – 2014-02-13T15:25:14.513
Sorry for the late reply, I was away from home. Gladiator2345: THANK YOU SO MUCH!!!! Please post your comment as an answer so I can mark it as accepted. When I was changing the ram, I disconnected the cmos battery just to be safe. This must have reset the bios changing back to sata enabled mode that I forgot I had disabled to allow xp to run. It's just like me to forget the most obvious things :P Xp sys information even recognizes 4gb of ram (although it only shows 2.64 as "available" task manager says 3gb total. Whatever the case, performance is now stunningly better. Thank you once again. – Blaine – 2014-02-22T09:01:19.580
