Well, first time posting on here, searched around a bit but found nothing.  Heres my problem.

I recently put a computer together because my old one was falling apart.  i picked up a matsonic motherboard with a 1.5ghz P4 i found for really cheap.  One stick of 512 ddr 3300 ram, Western Digital 80gig hd, ATI radeon 9550 256mb ddr AGP graphics card, and a seal 32 bit sound card, which uses a c-media driver, which windows said doesnt pass the "logo" test or something? basically having ot do with compatabilty.

Anyways, All my programs, IE 6, winamp, any games, etc, will just shutdown after using for  a while.  Games tend to shutdown faster than IE and Winamp, but basically, it acts like there is not enough memory.  IE: it takes longer for program to end on me after a reboot, and games end almost as soon as i start playing.  

I also get blue stop error screens from time to time.  My last one didnt say anything but a stop error code thing, (not to technical as you can read).  But the one before that said PNF_List_corrupt.  Ive also had ones that said Page_File_not_found.  

I also just added the 80 gig HD, since the only peice i reused was a 30 gig maxtor from my ancient comp, and i thought it was bad.  Since i have upgraded, the problems arent as frequent, and my available memory when no apps are running went from around 220mb to 350mb.  I beleive this would be whats allowing program to run a little longer.  

I beleive it is a memory problem, but what can i do.  Any help is appreciated, been DEALING with this for a few months now.  


OH, i upgraded to WINxp home with the service pack 2.  when i did the rebuild.  Im using a 450watt power supply too, with 3 case fans running, fan on teh processor, and two disc drives, one harddrive, no floppy.  THanx, danny.Sounds like a Windows problem.... Did you get all of your Windows updates?

[glb]Flame[/glb]Yep...It might be a heat ISSUE, try to use a different heat seek for your P4 if you can.  Hope this helps.Well, its never GONE over 104 ferenheit.  I think thats a decent temp.  Oh, heres my thread on anotehr forum, for anyoine watching this thread.  Good info...

Make sure it is set to let Windows manage my virtual memory.

On the advanced graphics settings try moving the SLIDER down a notch and then try. Keep moving it down until either the problem is fixed or it is as low as it will go (in which case this is not the solution.)

Go so start > run > dxdiag and run the tests. Results?

Get the latest Windows updates and install/reinstall the latest direct x and video drivers.

Scan for viruses as well. You never know... and you should do it regularly anyway.Thanx guys, ive been away for a while.

i will try all teh things you guys are mentioning.  

And for the psu, i was using one 450 watt, and now ive created a dual 450 watt setup, and it didnt fix my problem.  I got a better score in 3DMark2001 though, lol.  What would need 900 watts of power anyways.  lol.Oh, and when i try to play Ages of Mythology, it will just close on me, ussually after either watching the whole intro to the game, or if i skip that, a few minutes into the game.  It lets me play the game for about 5 minutes.  And then it just closes, no error message or anything.  IE and winamp will give me an error report message, and i ussually click dont send, takes a while.  

I ran the direct X thing, an dhad no errors, except once when i went to run teh direct3D test, it closed on me, like the game.  But i loaded it back up and it ran fine teh second time around.  

And i also just did the hardware acceleration test, and with EVERYTHING turned off, it still closed on me, but this time the graphics went out, still had sound, and then the whole game shutdown.is this an an old game the p4 maybe to fast for it??try cpu killer?>>http://www.cpukiller.com/Definatly not an old game, i highly doubt that is my problem.  Im sure it has something to do with every program closing though.  Liek IE and winamp(mp3 player).  Ive done everything from updating teh bios, turning off hardware accelerators, got all teh MS winxp updates.  The only thing i cant figure out is in sisoft sandra it says to update to MPS 1.04 or higher, but i cant figure out what its talkign about, ive searched on here and google.  Found nothing, and it also says my Processor is not running DEP, and some software is, so i need to upgrade for security reasons.  DOnt know how important that is.  

Oh, and could it be the fact that my stick of 512ddr is unregistered and unbuffered have anything to do with it?http://support.microsoft.com/kb/875352Reinstall your graphics drivers and directx.
