Imput on Voltages Please

[CounTDookU23]

Hello. I have started having these bad crashes recently. It started out once and a while..... then now my system has just started crashing more intermitantly. Sometimes just browsing the web.

I took this screen shot. I noticed that my 12V is has been running below 10.5... that is the first time I have ever seen that read out below 11.7 on my system. Could that be giving me random crashes?

I reinstalled a fresh copy of Windows 7.... ran a memory test on my Corsair sticks. So I decided to look in to the voltages.

What do you guys think or suggest?



My power supply is.......

PC Power & Cooling Silencer PPCS750QBL 750W ATX12V / EPS12V SLI Certified CrossFire Ready 80 PLUS Certified Active PFC Power Supply

If you've previously got correct readings from your motherboard's sensors with SpeedFan, then this is probably concerning. Sensors aren't very reliable though, and there's both a software and a hardware component behind that, so take them with a grain of salt.

Try with the mobo maker's voltage tool or in the BIOS monitor and see if the values match. If they do I suspect you probably do have a problem. If you've got a multimeter, you could check.

You were right. The readings in the bios, cpuz hardware monitor and speed fan are totally diffrent.

CPUz hardware monitor was showing a spike from 10.3 to 12.5........ then speedfan stays locked at 10.38....... so then I went in the bios and it stayed locked in at 11.98 on the +12 V.

I dont know what gives with these weird shut downs. Since I dont have a real voltage checker I decide to maybe do some stress testing. I ran prime 95 for a few hours and got no freezing..........even when browsing the internet..... starting a HD Movie file or running Zune Music software. All while Prime was running. I even ran Everest stress, Orthos for an hour or so each. No crash.

So last few crashes given me a blue screen of death just when browsing the internet. I dont know what else to check. My memory passed MemTest too. Arrrrrghhhhhh.

Halp.

BSODs are usually caused by buggy drivers.

BSODs are usually caused by buggy drivers.

I reinstalled Windows 7 and all the drivers I am using are newer revisions then what was on the previous install. Still the random lock ups.

This also is a Win7 system with all updates, the newly released Creative X-FI driver, ATI Catalyst and all of MSI's latest drivers.

After the reinstall finished and I landed in Windows....... I had installed Google Chrome....... BAM BSOD as soon as I tried to get back on the internet using it. Weird it can pass all this stress testing and crash on web browser with BSOD.

Maybe I should remove the new KLite Mega Codec pack and see if that might be crashing my system.

Just because they're the newest doesn't mean they're stable...

I'd probably try installing with just the Microsoft-provided drivers and see if things are any better.

It shouldn't be possible for codecs to crash the system.

What I meant was that my system was rock solid for a while using older drivers. Then all of a sudden the crashes started.

So figuring a clean install with newer non beta drivers then what I was using before would fix it.

By the way Windows BSOD after a clean install........ with nothing done except using IE to DL Chrome. After my google chrome install and I started the browser up...... my computer crashed.

Just as it did before with my older drivers and old installation of Windows 7.

And just like that they disappear. Had a consistent crash on any session I would work in Windows....... like it could be from starting the browser........ or hours later while playing around with the Zune Software. Now nothing....... 4 days and not one crash. Installed a bunch of newer games and have been rock solid for long weekend gaming session. Weird!
