Weird Net Problem

[yamangman]

Ok, I'm just gonna take you through what happend first...

One day, Internet Explorer unexpectedly crashed, so it gives me the 'do you want to send report' message, of course I dont, but no matter what I do, it won't go away. I CTRL-ALT-DEL, and click on drwatson32 (i think thats it) and click 'end process'. Immediately on pressing the button. I got a BSOD saying somthing along the lines off 'IRQ_less_than_number' somthing or other. Bit strange I thought, so I hit restart.

Now, whenever I connect, using an ADSL USB modem, after an indeterminate amount of time, the net traffic falls very low (a few bps), all open windows cease to work (Explorer, Outlook, BlueJ, Word, anything), I can't open anything (even CTRL-ALT-DEL dont work), and the only thing that functions is the taskbar. However as soon as I disconnect, everything works, it's as if the whole system has been put on hold waiting for somthing that hasn't happend....

Using an nForce II ultra 400 system on windows XP with all latest updates.

Now, any ideas? Anyone? Any Remedies? I don't want to format!

Cheers guys

Have you got the windows XP system restore turned on. If so you can try restoring to a date before your system started having this problem. Probably the easiest thing you can try.

possible USB issue mate

what PSU do you have and how many USB devices are connected to this PC

[yamangman]

Could be, but I've had no problems with it before the strange BSOD, so it seems unlikely. I have 5 devices attached and a 500 Watt PSU (more than enough i should imagine). A joystick, printer (often turned off), USB Modem, Digital Camera (rarely on, or even attached) and a USB flash drive (same as the camera).

Do you think I should disconnect some devices?

[yamangman]

Ok, I have used System Restore and it appears to have worked (I dislike using it normally). I checked Windows Update and this update:

Critical Update for ADODB.stream (KB870669)
Download size: 104 KB, < 1 minute
An issue has been identified that could allow an attacker to compromise a computer running Windows and gain complete control over it. You can help protect your computer by installing this update from Microsoft. After you install this item, you may have to restart your computer.

I had installed this prior to receceiving the BSOD, do you think this could have caused the problem?

installed it on my puter and haven't suffered any problems so far, basically if you can wait a week or two SP2 for XP will be out will have all the updates added to it so it may fix the problem instead of using the singular patch

[yamangman]

Ok, I spoke too soon and it hasn't actually worked. I expect I shall have to format unless anyone has any ideas? I might wait for SP2 first. It's 'proper doin' my nut in'.

OK, this is stupid, i've now reformatted totally unnecessarily, as it still happens. Next thing i'm going to check is the firewall, but other than that, i'm completely stumped. Can anyone recommend a good firewall, that allows you to setup program access and you can use and play online multiplayer without any problems? (not ZoneAlarm).

Cheers

[yamangman]

Ok it's not the firewall. What s it, the modem? Any tools you know of I can test it with? What the hell happend?

[yamangman]

Ok, it's not the modem, just tried it in another PC for a few hours no problems. I have noticed a few things.

The first, Windows XP is not recognizing the ACPI funtions of my computer. In device manager it just recognizes my system as 'Standard PC'. I have ACPI enabled in the BIOS but it still recognizes my system as a standard PC, so I can't put it into sleep mode. I've tried selecting Suspend to RAM and POS but it dosn't make a difference.

Second when I look at the properties of 'Standard PC', under IRQ steering, it says 'PCI IRQ Routing Disabled' and 'IRQ Table Not Found'. Also the boxes 'Use IRQ steering, Get IRQ table using MS Specification Table, and Get IRQ table from Real Mode PCIBIOS 2.1 Call' are checked. I also have APIC mode enabled. I bring this up because the initial BSOD i received had somthing to do with IRQ's.

Does anyone have any suggestions? Anything?

[killgORE]

so.. You tried a whole other computer... But not a different USB modem on the same computer ?

OR did you use the SAME modem with the different computer ? Just trying to clear things up !

[yamangman]

The same modem with a different computer It worked perfec.

[yamangman]

Does anyone have any ideas? This is doing my NUT in!

Its not the modem (tested in various PC's).

It's not the drivers (used various drivers and it worked fine for months beforehand).

It's not Windows (i have formatted twice).

It's not related to the ACPI/APIC problems I was having (possibly (now solved)).

It's not my Firewall (ZoneAlarm (stop laughing at the back)).

It's not the chipset drivers (worked fine before hand as well as trying different versions).

It is not related to any Windows updates (it just isn't).

I have run Memory Test for 18 hours no errors.

Most of the above are completely unnecessary tests anyway because I have tried it in different machines.

I have been trying to get it working on Linux but I can't set it up to dial the 'number'.

Bear in mind that it worked fine for months beforehand.

I've seen a similar problem with USB ISDN adapters; your SpeedTouch 330 is host-powered (i.e. power supplied by the USB port) and it may be that the USB port doesn't quite supply the level of juice needed. Doesn't have anything to do with your PSU as such, and it WILL work in other machines - I stumbled on this problem while attempting to get some Dell Latitudes working with Hayes Accura USB ISDN TAs and getting IRQL_NOT_LESS_... BSODs. Can you try either a PCI ADSL modem or an independently powered USB adapter - or even get hold of a powered USB hub?

edit: As far as the "Standard PC" thing, you should be able to replace the standard kernel with the ACPI one via CP, System, Device Manager - but take a backup and be prepared to reapply service pack(s) + updates.

[yamangman]

Cheers nichomach, but you can disregard most of what I said intially instead and just read my last post. You can't replace the HAL for a standard PC to an ACPI capable PC using device manager, you can only do it the other way around (ACPI to Standard). I posted my solution in the hardware thread. Your suggestion of using a powered USB adapter seems like a good idea, but the modem worked fine for many months before I started receiving this problem. Also since then, I have removed a PCI sound card, disabled 2 LAN adapters, both COM ports, parallel port and firewire are off so there should be no problems.

The only thing I can think of is that a portion of my motherboard is knackered, but I need to be sure before I send it back. WHat can I do, how can I make sure, where can I ask?

Cheers for your help

This is probably a silly question, but does it still crash whenrunning the cpu at stock speed?
