Windows 7: BSODs, IRQL_NOT_LESS_OR_EQUAL, Unstable System

07 Jan 2010   #1

Windows 7

I bought this computer at the end of last year, and put the components together myself. I installed windows 7 64bit, and I have had troubles ever since. First was a bad set of RAM, that I had to RMA. Also, the 770-C45 Motherboard has a power saving feature that shuts down the computer whenever it activates. I've since turned that off, and have gotten the system up and running, but I am still getting many BSODs, and lots of IRQL_NOT_LESS_OR_EQUAL. I can't figure out if this is a hardware problem, or software. I have yet to get this computer to work, and I have had it for over a month now.

Here are the specs for the computer.
AMD Phenom II X4 945 Deneb
MSI 770-C45
ATI Radeon HD 4850
4 GB of RAM
Western Digital 500 GB
Windows 7 64bit

Ran memtest last night, and it passed after 6 passes with no errors. I had to up the voltage to the RAM last time I installed to get it completely stable. Now it appears to be completely stable.

I attached the minidump to see if you guys could help me diagnose this problem. Thanks in advance.

My power supply is a Raidmax 730watt.

I went to disable ATI External Event Utility, but it wasn't in my services list. However, my computer has been running fine for about 30 minutes now, which is considerably longer than it usually does. Thanks for the help so far. I will keep using it and update if anything goes wrong.

On my system it's called AMD External Events Utility (HD 4870)

ATI External Event Utility has been the cause of some BSOD's also that RAIDMAX PSU may not be delivering enough amps on the +12 volt rail I think that is a dual rail system with about 24 amps on the +12 volt rail you need to get that to about 40 with a big video card and quad core CPU

Is there any way to verify whether or not my psu is giving enough juice to the rails? I don't want to buy a new power supply, but if this is the cause of my errors, I definitely want to upgrade. Thanks,

Well, my computer ran fine for about a day, and earlier today, everytime I tried to open an application, it would give me an error. Rebooted and everything was working again. Opened Outlook and computer crashed. Here is a new minidump file. Is it the same problem still? Thanks,
