Various Corrupt Messages on Blue Screen (windows XP Pro SP2)

Hi there, I've been having problems with my pc for a few days now, with it trying to restart itself automatically and not being able to start at all sometimes. I was getting a bluescreen for a split second, saying PFN_LIST_CORRUPT and a bunch of other stuff that I couldn't read as it just flashed on and off so quickly. I was told that it could be a memory problem. My motherboard is a Biostar M7NCG 400 and there were 3x sticks of 512Kb Ram in it. I removed the stick from DIMM Slot B2, Restarted the PC & it worked fine (showing 1Gb of RAM now instead of 1.5Gb). I defraged the pc & ran the following programs; RegscrubXP; AVG; CCleaner; Ad-aware & SpyBot S & D. It ran for approximately 12hours yesterday without restarting. Today, I decided to swap the removed ram stick with the one in Slot B1 and again it worked fine. I decided to try the other stick back in the B2 slot and on restart, had the same problems with restarting automatically etc. I also saw a blue screen at various times over the last few days, saying something like IRQ, but again, it flashed on and off so quickly that I couldn't read it properly. I'm suspecting it's a motherboard issue, but I'm no expert and I'm wondering if there is any way to test the motherboard to see what the problem actually is. Other system details as follows; CPU = AMD AnthlonXP 2400+ Power supply = 230v Graphics = Nvidia Quadro4 700 XGL 1x CD ROM & 1x DVD-RW 2x HDD 1x Modem (not used)

Re: Various Corrupt Messages on Blue Screen (windows XP...

I have worked on several computers with simular problems. First your ram. Are you making sure that the ram sticks all have the same speed? the other thing you might want to look in your manufacture technical books to see if you are using the right amount of ram for that specified slot. Many motherboards have maximum ram for each slot. Speed of your ram sticks is very important never mix them together. always use the same speed. Using varing speeds you could have a whole host of problems. I found that if you mix the speed of the ram sticks you can cause the registry , bios and even your IRQ settings to malfunction or make entries that cause your computer to fail. The other thing I see is you might want to up your PSU 230W for a AMD and the graphics card is quite low. I would recomend at least a 450w or even a 500w dual 12 volt rail. This will make sure that enough power is going to your motherboard and also to your graphics card. Note: Using mixing speeds on your ram sticks over time can cause perminate damage. When your PSU is under powered you can also have what i call creeping problems. What I mean by this is that as the PSU gets overloaded slowly things begin to malfunction eventually leading to a full shut of your PSU. I have only seen on a few overloaded PSU it damaging a componet on your motherboard. But once again it all depends on how it happened and what was the load when it occured. I hope this helps if you have a comment or more questions feel free to contact me.

Re: Various Corrupt Messages on Blue Screen (windows XP...

Hi, in my repair workshop I have seen this problem several times and almost always it is a problem with blown capacitors on the mobo. When you have the case open again inspect the capacitors, [they are the round objects grouped together in lots of 5/6 on your bourd] If any show signs of bulging at the top or leakage from the bottom, unfortunately its time to replace the mobo. This can be fixed but the labour cost will almost equal a new board. Goodluck mistyman

Error code

Apparently the XP Pro CD you are using is pre-SP2, thus causing the error. With XP RTM and SP1, you need to supply the proper SATA drivers for the chipset on the motherboard since there is no built-in support for SATA drives. You can download the drivers from

During the XP setup you will need to press F6 to install these driver before attempting to copy the XP files to the drive. Or you could make a custom XP CD using the directions at that has these SATA drivers already slipstreamed into the installation procedure.

Or if you know someone who has the WinXP Pro SP2 CD, you could borrow that for the install.

Tis about REALTEK blahblah...i cannot see the volume tray icon

As you said you have formatted Drive C:, and installed XP SP3 and back again XP SP2.
Why don't you try formating the whole drive and reinstalling fresh Win XP SP2 and always choose NTFS partition only because all the features are supported in this partition.

Problem w/ Pcchips A13G+

PC-Chips infamous for memory controller issues.

In the BIOS, set the memory speed to the highest CAS and lowest speed. Make sure FSB and memory timing are asynchronous so you can slow the memory. Turn off interleave, etc...
Is your memory mismatched? Use one stick, and pick the best one.
Try a different one.
Almost guarantee it is a memory issue of some sort.

Gigabyte GA-MA790FX-DQ6 installation problems

Hi speedfreak44, during the installation of windows one of the drivers did not install correctly & windows registry is messed up.
The blue screen is a typical response from windows. Even though you're windows installed SP2, there are another 89+ updates for SP2. (A reinstall with-out a format is not advised).
Suggest you enter you're bios & disable ACPI. This one I know for sure will show up in windows device manager as a PCI device with no name. Try again to boot windows. If it still fails to enter in standard mode than a complete re-install will be required including a format. Personally I do not use windows XP pro/home w/SP2 CD to perform the format, (After receiving a blue screen).
I have found it is 98% better to use the software tools, downloaded from the Mfg's web site for you're hard drive. Use the bootable software (On a floppy or CD), to format you're hard drive. Most Mfg's hard drive software will allow you to change the cluster size up. Windows standard uses a 4kb cluster size & you loose far more hard drive space. With a 16kb you loose only the file allocation or FAT, which is normal.
Than using the Win XP CD/SP2 install windows, clean.
(No need to format).
When finished installing windows, load the Gigabyte driver CD & install the chipset & other CD drivers. Turn on windows firewall & update windows SP2. (ASAP), (Save SP3 update for later).
It is in the updates of windows to iron out software & hardware driver updates. Do not install you're antivirus software until windows has finished updating its self & you install any hardware updates also through windows update. (Continue to leave the ACPI disabled in bios until updating is complete).
You can enable ACPI, antivirus software & printer software all.

You will find some needed software will install during windows update. Like; Quad Core processor update. With either home edition or pro it is advised to install .Net framework updates 1 at a time & only restart when prompted by windows. Other wise click the refresh button & continue windows updating. (You can save the .Net framework updates for last if you wish). You're video card may need .Net framework 2.0 or better for installation.
I am hell bent on installing windows once & correctly the first time. I understand you want to get this baby up & running but take the time & run the hard drive tools/utilities. (It's worth it)!

Good Luck speedfreak44!
If I can help you further, feel free to post.
Suggestions & comments welcomed.

Please let me know if this got you're system running without the blue screens?
One last item. It's also worth checking the dates on the Gigabyte CD to Gigabyte's web site before installing other drivers. Including the chipset drivers. You want to install the newest drivers the first time around. Here is the link to you're Gigabyte GA-MA790FX-DQ6 motherboard main web site.

Have you tried a Motherboard Bios Firmware Upgrade? It should be readily available on the Manufacturers Website.. There are a number of diagnostics you can do to pin-point the actual malfunctioning component, rest assured everythings stable with the softwares being used and the OS environment is virus/spyware free! you can 1st upgrade the Bios to the most latest (Non-Beta) version.. If that doesn't help, try a single 512mb Memory Stick, one by one and notice if that helps with the (BSOD) errors..
