System:
Windows XP Pro SP2
AMD Athlon XP 1800 (1.53 GHz)
512 of ram

My system sometimes restarts and I got this in the event viewer:
Event ID: 1003, Category: 102, Source: System Error
Error code 100000d1, parameter1 00000000, parameter2 00000002, parameter3 00000001, parameter4 f3afec04.
The BSoD error is about "DRIVER_IRQL_NOT_LESS_OR_EQUAL"

I tried to find a solution by reading all the posts that deal with event ID 1003 and HTTP.sys but nobody has the "HTTP!UlIsLowNPPCondition+55" that I've seen in the minidump files...
I've already run a 10 passess Memtest86+ test and there's no RAM error...

So I am appealing to the forum to see if anybody could help/save me.

All logs (except 1) go to HTTP.sys
Usually you are also given Error logs in Start > Run > c:\windows\system32\logfiles httperr logs?
You might need to check that out

Also one Minidump went to klif.sys (Kaspersky) But the file mentioned was: NotMyfault.exe (Driver Bug test program)

Since you are trying to "test" your drivers, I would highly recommend you update to SP3 as a better option

Hi kimsland,
I've fond one httperr log but it doesn't help me as I can't make any conclusion. Its content is:

Yes, I tried if NotMyfault could help me but it just produced more BSoD so I didn't insit...
Any idea of what could produce those errors?

Hi,

I eventually (after much hair pulling) fixed this problem on my computer by changing a BIOS setting that upped the voltage to my RAM (this was after swapping out almost every component) - after much googling I came across a vague reference to RAM sometimes needing more current when running under load (MemTest did not put enough load on it - running Assassin Creed did)

Another possibility to check is whether your CPU is running cool enough when under load.

Looks like Malware to me
Try running through this guide: http://www.techspot.com/vb/topic58138.html
But you cannot submit those logs in this sub-forum, they go to: Virus & Malware removal forum (if required)

AfricanTech: I've looked at my BIOS and I can't find any setting about RAM changing voltage (I just see DRAM clock, timing and CAS latency adjustments). Could you tell me the name of the setting you changed in your BIOS to see if I can find a similar one?
I've also tried to stress my ram under Windows with Memtest 4 (from HCI Design) but there is no BSoD...
I checked my CPU temperature and it's about 61-64ºC (143F). I don't think it's too much, isn't it?

kimsland: I don't thing it can be a malware as I restored an Acronis backup with just Windows and the drivers I've always been using (BSoD started 2 weeks ago and I recovered my Acronis backup 5 days ago and BSoD didn't disappear...) Do you thing HTTP.sys means my network adapter could be the guilty? Or could it be anything (hard drive etc...)?

Thanks a lot for your help. I'm really desperate...

I've noticed that the BSoD ALWAYS happens when I am running a complete disk check of an external hard drive. It also happens in other moments (when the external hard drive is not connected) but always while I'am running the check disk.
Does anybody can draw a conclusion from that?

Hi

I found it under the Advanced Settings menu - your BIOS might not allow access to that setting - check with m/board manufacturer.

Sorry I can't be of more help.

Good luck.
