Hi,
I have just now joined this group.Esp. after seeing this thread.
I own a AMD64 with ASUS K87 MOBO and PC3200 DDR RAM.
Have faced the same problem on numerous occasions.Not able to solve the problem till now.
Have faced a blue screen error message sometime ago (not able to remember exact message) at random times but it was solved when i identified the culprit to be Zone Alarm firewall.After uninstalling it i have solved that Blue screen riddle.......
But after that i have faced different types of blue screen (I.e Error messages)
One being IRQ_LESS_OR_NOT_EQUAL.This frequently happens when i close the Prince of persia warrior within game and also when i use the PC extensively for more hours.
Yesterday i tried writing a cd using Nero...after it came around 87% my system gave me a different blue screen but this time error message was KERNEL_DATA_INPAGE_ERROR. Now i am not able to get into my computer it restarts after showing this error message.
Do you think it may be some sort of memory problem?

Please somebody help me.
Thank you very much

Jephree, thank you for your constant patient help . I did everything you said (except the BIOS thing since I am really not good at it and I don't want to ruin anything) and until now no more blue screens. The Nod32 was not Read-Only, but I now ticked it like you said. And also I made these registry modifications .

Hope it all stay fine after all...although I still don't understand what the problem was .

Glad to help. Not sure what was wrong but apparently "something" was altering (writing) NOD files. This is usually a virus or malware.
Just keep up your scans; Online as well as Spybot & Adaware.

Let us know if we can help further
