In Reference to this thread: http://forums.anandtech.com/showthread.php?t=2054483&highlight=

intel E8400
Asus motherboard p35 PKE wifi( i forget the exact model im at work)
EVGA 8800 GTS 512
4 gig Gskill ram ddr2 800 4 1 gig sticks
Seasonic 550w psu (not the problem)
Windows 7 (but problems have been happening even when i had XP)

So this is my setup and here are the tests i have performed so far.
1. have run Memtest for countless hours without an error.

2. Windows memory diagnostic freezes up at 22% everytime even when testing 1 gig at a time in multiple different dimm slots.

3. Prime 95 gets this error FATAL ERROR: Rounding was 0.5, expected less than 0.4 Hardware failure detected, consult stress.txt file. Happens to one core and then the other.

4. My cpu temps are at 40c at load and my video card is at 40c at idle.

5. My PSU voltages dont move at all when under load.

6. I have tested by pulling out a stick of ram at a time so there was only 3 gig of ram in my mobo and it still gets bsods after testing them all.

7. The dump file indicates In blue screen view its saying its Driver corrupted expool error. A different file crashes each time i get a bsod.

8. In games the computer jsut stutters for about 3 seconds when an error occurs, but doesnt bsod.

9. Have manually set the voltages and timings of my ram and this didnt work.

10. My computer is not overclocked at all.

I am not sure where to go from here. I ahte to start buying replacement parts if its not the culprit. Any suggestions would be great.
 
Did you try giving the CPU a little bump in voltage?
When they say try one stick of ram they mean use 1 stick. Not remove one of the four. Could be a bad stick of ram.

i did test one stick at a time, had an error on each stick useing windows memory diagnostic. No errors in Memtest.

I doubt every stick of ram is bad so we can probably eliminate that.
When do these bsod occur most? Randomly or when loading games?
 
What else do you have in your rig? Any wireless cards, tv tuners, etc?
Did you run any software to see if your hard drive is functioning properly?

Wireless on the board is disabled. Only a video card, dual display isnt setup. Havent run any hard disk programs. Its odd. I only get BSOD's when i am running internet explorer or itunes. It seems to happen when i click on a link on a webpage, but its not specific.

When i am playing games though i do not get bsods. When i game the game stutters or freezes for about 3-5 seconds and then continues sometimes like normal, sometimes with a lower frame rate and i have to restart the game. I think its the same problem, but when im at the desktop it BSODs and in game it freezes briefly.

What do i use to test my hard drive? Could it possibly be a driver?
 
Hmm, you said memtest comes up clean. Sure does sound like a memory issue but its highly unlikely every stick would be bad, but not impossible.

Could be bad motherboard, but memtest would prolly catch that. Or possibly bad CPU.

The only thing i could think of trying is doing a fresh windows install and see if it still does it, could also be a corrupt windows install. Have you checked your disk for errors? If not try that and also make it verify free space (surface scan).

EDIT: Oh hmm, you said it did it in XP also. when running Memtest, did you do it one stick at a time and run the extended test?

Didnt run memtest on each stick seperatly yet. Did run memtest with all the sticks for about 15 hours and no errors. Ill try it tonight. I already did a fresh install. Maybe I will try another, but I have been having these problems with the release client of windows 7, windows xp and now my home premium version of windows 7. So i doubt its a abd install. I wish it was that easy.
 
Have you tried underclocking your ram? Running it at a slower speed but still at a 1:1 ratio you wouldn't lose any performance. I'm not convinced you set your ram timings correctly or the voltage. What ram is it? Just paste the newegg link.

This is my ram.

I set my ram to 5-5-5-15 and 1.8v to 1.95v. I tested the ram at those voltages and each voltage I received a BSOD. How do you underclock ram?
 
go into bios and put 5-5-5-15 as timing 1.9v and there should be a memory divider setting you can use. Use 1:1 ratio and it should underclock your ram.
Save those settings in bios and it will reboot and hopefully that will solve your problem. Report back either way and next we'll try giving the cpu a slight bump in voltage and see what that does.
 
Ok i set the ram to 5-5-5-15 v to 1.9 and the frequency to 667 to have the divider at 1:1. I will up date either way and run prime 95 tonight
 
Try using only 1 stick of ram a time, running 3 doesn't eliminate that 2 could be bad.
If you have any extra sticks as well you ought to use them, or you can grab a cheap 1gb stick from fs/ft for like 10 bucks or something.

Make sure you have no other peripherals connected that you aren't using. Sometimes simple things such as random USB inputs or even the CD drive can cause bsods if they are bad.

That's all I can think of from what's been mentioned thus far. Only thing left is MB. Nothing else should be causing BSOD's, other than the vidcard.
 
I to am suspecting the motherboard. Have you reset the bios by taking the mobo battery out for a couple mins? I'd hate for you to replace parts at my recommendation and that not be it. If you know anyone with a similar rig I'd hit them up for some testing.
 
Are you absolutely sure it's not the power supply? Also, it'll sound odd, but have you tried jiggling the computer when the tests are running? Most intermittent hardware issues, if it's not failing hardware are loose connections, jumpers or screws, and even lost screws causing shorts or odd grounds.
 
eh when testing the PSU voltage doesnt move at all. The PSU works just fine as far as i can tell.

This kinda sucks. Like a crap shoot. Not sure what to do from here. Wish I needed a new computer. I am sick of testing ram though. 🙂 Wish i had someone to swap out parts with
 
Windows Memory Diagnostic and Prime 95 erroring out, but Memtest running ok is a stickler. Can you try running Prime 95 in safe mode? Can you also try running cpuburn. I have yet to see any other program that can heat up CPUs as much as cpuburn. Althought I'd love to hear of any new ones that do, since it's OLD.
 
Stupid question: are you using the most recent BIOS?
I had a problem with the G.Skill-Asus combination solved by flashing the bios.

Calculator. Factor a million once per core. Sometimes on quad cores you only need 3 instances. But run calc, switch scientific, put in a million and factor it. It will instantly peg a single core. The second instance will peg a dual core. And a third and/or fourth instance will peg a quad core. 100% load.

Ive used it for the last 7 years to heat up processors to either test them or make sure the machine is cooling properly.
