PFN_list_corrupt

[throdgrain]

Well, this is a new one for me

While looking at Facebook today I clicked on a picture (of Odin, if you're interested) and the pc just hung.

Couldnt ctr-alt-del or anything, just had to press the reset button. The computer then restarted, but the monitor didnt come on. I reseated the video card, nothing, mucked about a bit, and eventually the picture returned. I started windows normally, it didnt start, and went blue screen. Error message PFN_list_corrupted. Obviously I'm googling for answers, but most of them appear to say download this or that, I cant do that, as I can start windows. Or maybe I can, but the monitor is not showing a picture.

I've tried ;

changing the monitor
changing the video card
reseating the ram

no good. Any ideas? I'm a bit lost.

Hmm, do you have the full stopcode?

 

[cHodAX]

Oh and don't download a fucking thing mate, a ton of malware is coming up from my google searches.

Basically it seems to be either a driver issue, bad memory or a data corruption on your hard drive. Start with the driver, get into safe mode.

 

[throdgrain]

I think it was 0x000004 or something like that. Problem is, I cant see what the pc is doing to find out whats wrong.

 

[cHodAX]

Ok, you know how to get it into safemode?

When you get the safemode menu, try 'last known good configuration' first, if it still crashes then select safemode with networking and let it boot.

Can't see anything at all? Not even the boot screen?

 

[throdgrain]

No, this is the problem! The pc crashed, restarted and gave the blue screen, I 've tried to boot into safe mode, but the picture just froze. On about the 5th attempt I thought it might be a corrupt OS, so out of desparation I thought I'd reinstall, but the screen froze even when I did that. Next reboot, no picture at all. The monitor is showing no picture, it's not on at all, the "on/off " light is flashing. The pc is running, fans going round, but I cant tell whats happening as there's no picture on the monitor. I tried turning the monitor off and on with the pc running, and the DIGITAL sign in the corner came up changed to ANALOGUE, then back again, 3 or 4 times, the it's gone, and the on/off light is flashing again.

Ok, can you take the graphics card out and reboot the PC without it? If so then do that. Leave it switched on for a min until the hard-drive stops accessing. Then power off, put the graphics card back in and try reboot again. If no picture but you get power on beeps followed by hard drive access then it looks as if your graphics card might be fucked.

 

[throdgrain]

OK I've found a VGA cable and adaptor, and fired up the pc, and hey presto I've got a picture! So, I started up windows, which said I hadnt booted properly, so I hit fix problem, which brings up a screen needing a mouse, then I notice I havent got a mouse at all. I unplug my mouse from the usb port at the back and plugged it in the aux port at the front, and it appears.

I wonder if me motherboard is fucked actually.

 

[cHodAX]

Yes I have seen that recently with a mates PC, one of the USB ports goes on the fritz, usb driver crashes and fucks all the device enumeration up.

Is your PC running ok at the moment? It may just be a single USB channel that has gone and you can still run safely enough.

 

[throdgrain]

I've been posting from me laptop, but I'm now back on the pc, thank god. I've plugged the mouse back into the back of the pc, and it's working normally. The only difference now is that I'm running in analogue instead of digital picture. I honestly dont know whats wrong, and I dont like it!

 

[cHodAX]

Onboard graphics?

 

[throdgrain]

There is none. My pc, by the way, is an Asus P8P67 pro, with an Intel i7, with 4 gig Corsair ram and a GTX560i.

 

[cHodAX]

Ok, so if you have video via the VGA port then the DVI/HDMI should still be working. Give it a try now it is booted up. It does sound like one of your USB ports went *pop* and the resulting crash screwed the system a bit, now that you are back in windows it should all be sorted though.

 

[throdgrain]

Yeah Im *hoping* it may sort itself.

I connected the old fashioned VGA cable to the monitor, disconnected the digital one. then fitted an adaptor to my video card for the vga cable, and it works.

I suspect that if I reconnect the digital cable now and remove the vga it will be ok, but Im not going to do it tonight. Because I'm scared!

Niether does it fix that blue screen error I got, although I have deleted and reinstalled my video drivers, which may help.

 

[cHodAX]

Run the driver verifier...

 

[throdgrain]

Nice one, didnt tell me much though, Ill look again tomorrow. Thanks for your input

I had this Throdgrain, and it turned out one of my sticks of RAM was dead. I downloaded a RAM diagnostic to confirm it (can't remember the name, sorry), then just located the dead stick through trial and error, replaced it and it was fine after that.

edit - this was the tool http://www.memtest.org/

 

[throdgrain]

Aoami - thanks mate, yeah I actually ordered 8 gb of ram last night for this, my pc is running quite slow now too. For example, as a test, I played some CS:S, normally it bangs off the fps limiter at 300 fps, now it's running at about 120 - ish. Obviously playing newer games the problem is accentuated.

So I got 8gb of ram coming tomorrow, and Im backing up stuff right now to reinstall Win7 just for good measure
