Athlon 250/3.0GHz
MSI 785GT-E63
4GB OCZ Platinum DDR2-8600
HD Radeon 5830
750W Antec EarthWatts PSU
Latest drivers and bios
CPU Temp: 35C-40C at max
C1E - Disabled
Spread Spectrum - Disabled
CPU Phase Control - Disabled
- tried the last 3 settings on as default just to if it made any difference, and non was noticed (good or bad)


After toying around with OCing on my new rig everything went fine but until I started using AMD OD it just kept slowing it down more and more with each tweak I did. My simple OC soon became unstable and even at factory defaults and cmos wipes it still hung and with no avail on memtest, HDD checks, and recently confirmed, no software problem either (I just reformatted the other night). By unstable, I mean that my CPU load will jump excessively high on the simplest things like opening the task manager and this spikes my performance and creates stutters and lagging moments on simplest tasks. The worse it is, the more Everest shows my bus speed fluctuating from moderate to extreme lows depending on CPU load.
Edit: Just about anything over uses my CPU load and just about anything can slow it down or spike the usage (even firefox)

This affects my FPS and smooth frames and things that need to be loaded stutter and delay the CPU by increasing the CPU load dramatically which makes for low and annoying FPS when playing World of Warcraft. I also use to get higher FPS pre overclocked when I put it all together.

I noticed my HT/NB have a deciding factor in this, like it's more stable at 2000 for HT and NB but if they're different numbers things tends to fluctuate more (but increasing the NB makes loading and everything noticeably faster) but the higher the NB got from HT it seemed more unstable (theory). After formatting my HDD I cleared my cmos and reinstalled Windows 7 and made no real difference other than a faster OS

Even though computer runs stable and won't crash and voltages had zero to do this the problem and my CPU temps are pretty low. I checked my PSU and it handles the voltage to everything just fine but it seemed like when I disconnected 3 case fans that were pretty much ineffective due to touching up against the fans on my CPU heatsink, it got considerably slow and laggy and even crashed due to normal CPU related crashes (overheating or insufficient voltage and it definitely was not voltage). Plugged fans back in and problems pretty much was solved, but yet, my temps never up or anything, just a crazy bus speed on Everest and Everest only (yet it's the only thing that connects the lag to some numbers). (even my bios temps don't get out of normal range)

No one has been able to help me and I'm quite confused. I'm almost positive it has to do with my heatsink or thermal paste but my temp numbers don't spike and that's the only difference between my situation and many others (yet 3 programs all register the same temps+the bios) so my question is...could that be it? I only have so much thermal paste left and would rather not try digging into that without knowing the possibilities. Though I will say it all originally started before I changed my stock CPU heatsink.

3944648297 was the max but I have no clue how it spiked to that and was thinking maybe that's when I was afk and my monitor turned off or something
avg was 60-80 but I never had a really good chance to test it on WoW during the more intensive times of the day.

I think you have a driver conflict but it's impossible to pinpoint it. A new OS install might sole the problems.

I've done 3 formats since the problem showed up, I'm not exactly sure that's it. I even tried running WoW before anything else other than my display driver was installed and it was still there. Then I updated Windows and slowly updated everything and it was pretty much all the same except for more stuff bogging down the system.

Nothing spikes and never goes much past the avg that I posted above.

Try with this
http://technet.microsoft.com/en-us/sysinternals/bb89665...

Very probable you keep installing the application that causes the spikes. At the next OS reinstall don't install any application but the drives for the mobo + video card and see if this happens again. Then install the other applications one by one and test the system after each one. Also you can try some other OS.

i believe its a GPU related issue. Anything that your OS uses to produce a GUI is causing the GPU driver to malfunction.

what board maker is the HD5830? probably the TIM on the GPU might've been poorly applied at factory and may have lost its thermal ability - it could be a possiblity, not that it happened.

Go into windows error report and post back what the error message was in the critical error section. I've noticed on another post with the same mobo have an error appear cos of NB malfunctions...

check and see if the fan connections are connected accordingly (not saying your a noob) but it pays to double check and be sure. BTW what TIM and HSF are you using anyway?
