So many blue screens XP and W2k...please help me.

Question

Thanks for all the advice, Now for a conundrum that is linked (I bealive) to the IRQL....Blue Screen Stop Error.
as a reminder the system hardwear setup at current is this:
1) 1x VData 333mhz PC2700 256mb 2.5v Ram (installed in slot one)
2) 1800+ AMD
3) Sony DVD-ROM (Secondary Master)
4) IBM DTLA-307045 7200Rpm (Primary Master)
5) CoDegen 300w PSU
6)Radeon 9100 Atlantis 128mb DDR AGP x4 G/Card
7) MSI 745 Ultra Main board
 EIDE 40pin/40wire cable from SonyDVD -> IDE1
9) 40pin/80 wire IDE UDMA cable from IBM HD -> IDE0
I have turned of all caching apart from the internal cache with the Auto PNP OS in the bios disabled and the rest of the settings on default, I have also updated the Bios from AMi 1.4 to AMI 1.5. On trying to install W2k I recive (half way through the installation) randomly the following Blue screen stop errors:
a) 0x00000050
b) 0x0000001a
c) 0x00000023
d) KMODE_....can't remember the rest (at work)
e) PAGE_FAULT_IN_NONPAGED_AREA
on XP installation I get the following:
a) 0x00000050
b) 000000008e
c) PAGE_FAULT_IN_NONPAGED_AREA
d) 0x0000007b
I have tried installing XP with the internal cache disabled and it works very slowly but does eventually install XP, on enabaling internal caching XP blue screens and restarts the computer automaticlly after around 5 - 30 mins of use. the same with windows 2000 but it freezes on starting up the first time.
I have also run memtest86 v2.9 for 3 hours and it has come up with the following results (total errors are 82):
badram patterns:
0x0fe15008,0x0fe15008,0x0dd11008,0x0dd11008,0x0f714808,0x0f714808,0x0de14c0 8,0xffffffc,0x0c70d000,0x0c70d000,0x0de14a78,0xffffffc,0x0de14ac8,0x0de14b1 8,0xffffffc,0x0d701008,0x0d701008,0x0b529008,0x0b529008
on this I would go out and buy new ram, but as the problem only comes up (for XP) when I enable internal cache, could it be the Stick of ram or the CPU Cache? I have been told by a local dealer that Xp does not like Cache, how can this be? it slows the system down so much when disabled. I am almost in dispare on the problem. please could someone help. I'm confused weather its the CPU or memory stick or (dread to think) the motherboad or even all 3.  
Many thanks,
Quinton. ;(

Answer 1

I had very similar probs with xp. Blue screens and all that half way through copying installation files. It would go to various percentages of copying the files when the blue screens would come up, variuos errors would come up. I was using 256mb DDR PC2100 and i swapped it with some 256mb DDR PC2700 and i installed xp ok after that. I will be able to tell shortly if the mem module was knackered when i try to install it into another machine. i found the error codes on MS website by putting the error codes into google and searching and the codes pointed to ram being at fault.
