This is driving me nuts! I keep getting these stop messages! Most of the time I can’t see what the message is because the screen goes blank, but sometimes if I push some keys (this only worked twice so far) the screen will come back and I can read the message, I found this out by mashing the keys with my fist in anger. :) Here are the messages I’ve been able to read so far: Unexpected_Kernel_Mode_Trap And… Driver_Irql_Not_Less_Or_Equal And NONE of my games work correctly, Midtown Madness is choppy, UT2003 gives me a “General protection fault!” error, and Deadly Dozen generates errors. Do you think my cheap-ass raid card is causing this? I know the CPU is not overheating because I ran Prime95 all night @ 65C with no problems, but as soon as I started using it today I got another stop error (I think, It wouldn’t let me see though). And Microsoft memory tester says my ram is fine, but can it be trusted? New egg.com has a 30-day refund policy, so I have about 25 days left to find out if this is software of hardware problem. Here are my specs in case you need them: (I built this computer my self by the way; I have built 4 machines so far, and have never had this kind of trouble with any of them!) OS: Windows 2000 SP4 Processor: AMD XP3000+ 400 MHz FSB Heat sink: Speeze "Falcon Rock" Mobo: Shuttle AN35N Ultra Memory: 512MB PC 3200, Mushkin Basic green Graphics: 256MB Evga Nvidia Geforce FX 5500 Raid Card: Koutech SIS Sil680. Hard drives (RAID0): 40GB 7200RPM Western Digital 2MB Cache, 40GB 7200RPM Seagate 2MB Cache. Hard Drives (connected to onboard IDE controller): Western digital 30GB 5400RPM. CD Burner (connected to onboard IDE controller): Lite-On 52327S Modem: Actiontec V.92 I really REALLY appreciate any help you can give. This thing is basically an $800 paper wait right now!

can you try to run the machine with out the raid array?.. if you think that is the problem? have you also checked on driver updates for the raid controller?

also a more solid memory testing proggy is here... http://www.memtest86.com/ i would start it before you go to bed and let it run all night for a 'sure' test

I am using the latest divers for my Raid card. Thanks for the link Johnstun, I will try that. And thank you both for replying to my question! I've posted this question in a couple other forums and no one has replied yet.

Oh yeah, forgot to mention when I put this thing together I forgot to hook up the P4 connector, it ran for about 9 hours without it (Perfectly stable by the way). Could that of did something? Symbios
