hi, anyone who can help me figure out the cause of this problem will earn my respect and admiration! :D ok, i have a chaintech 7njl6 socket a motherboard with an athlon XP processor - i believe it's a 2200+ model im running windows XP- a few months ago my computer wouldn't even boot properly - it would just hang, bios wouldn't even load. i tried replacing it part by part, i ended up buying ALL new hardware, except for the hard drives, RAM, and power supply. that fixed the problem, BUT the computer will still freeze up in XP, sometimes after 10 min of use, sometimes after 10 hours. it just freezes. that's what it does most of the time - but occasionally it will go to the Blue screen "PAGE_FAULT_IN_UNPAGED_AREA" or something like that. and it says "Writing memory dump to hard drive" or something to that effect at the bottom of the screen. it counts up to 60 or so and then it just freezes. that happens about 1 out of every 5 times it crashes. occasionally it also reboots itself, but that's even more rare. anyone know what might be causing this? is this an internal hard drive problem? i've tried alternating boot drives, that doesn't change anything (i have 4 hd's) thanks a lot peeps, i really REALLY appreciate your help! Matt

My first suspect would be a bad memory module. If you have 2 pull one out and run it. If it still happens swap them.

hmm that might be it. i only have one module in there. i guess ill buy another and see if that helps. thanks~!

Post back and let us know for future reference.

thanks, i will! i need help figuring out what type of modules to buy though! heh. i mean, in terms of PC____ - the manual for my motherboard (Chaintech CT-7NJL6) doesn't specify. this is what it says in the manual: DDR SDRAM specifications: Mem Freq / Internal System Bus Freq -------- 133 mhz 266 mhz 166 mhz 333 mhz 200 mhz 400 mhz DIMM type: 2.5V, unbuffered, 184 pin 64/128/256/512-bit DDR SDRAM Module size: single/double-sided 64/128/256/512MB/1GB Parity: either --- I'm planning on getting 2 sticks, the max the board takes is 1gb total. so yeah, any help figuring out the PC2100 or PCwhatever part of this would be a big help. thanks!

Go to crucial.com. They will size and tell you what is proper for the machine.

ok, ordered a stick http://www.buyaib.com/index.asp?PageAction=VIEWPROD&ProdID=728 the Infineon Brand one - for $69. includes a cooler. so it turns out with the nvidia nforce2 chipset that my motherboard has, there are RAM compatibility issues. supposedly this chip will work fine - guaranteed compatible. also, i got another blue screen message - this time it says BAD_POOL_CALLER. no idea what that means. maybe you guys do ?
