Quad core build freez ups

[philbar71]

well a couple of weeks ago me and my dad built a new computer to replace his aging p4 system and so we got all the parts off the egg and put it all together and tried to load win vista x64 bit ant it kept freezing up, so we did some research on the net and found that the mobo set the ram to 1.5v instead of 1.8v. so we manually set it to 1.8v and the install went fine. then when it's all loaded up we put on mobo drivers video drivers and sound drivers as well as drivers for the tv tuner card. and then my dad puts trent micro antivirus on it. so after all that we started playing around on it and then without warning or a bluescreen it just freezes. the audio loops and the only thing to do is reset the computer. now, we've done lots to trouble shoot it. like fiddling around with the ram sticks taking some out and putting them in diff slots. we have also swapped his gtx260 with my 9800gtx and still same thing. it's not a overheating because in games(crysis demo, cod4, ect) the hotttest the cpu gets is like 55c now that is a bit warm but thats also on core 0. core 1,2,3 are about 10c cooler and the northbridge barley gets over 60c and i've never seen the gtx 260 get over 65c. this all under full load. and in top of that we have installed latest bios updates.

IMO you should start in safe mode (if you can't load normally at all) and rollback the drivers one at a time. Rollback your video first, then sound, etc. Restart after every rollback and see if the BSoD shows up. At that point you should be able to determind which driver is causing the issue.

Since everything worked fine prior to install of the new drivers I believe there is probably a driver on there not suitable for the 64 bit or Vista environment.

well the thing is this is a brand new build and all drivers were from the cd then from the manurfactures web site. but i will try rolling back the drivers and we'll see if that fixes it and i'll try to load in to safe mode and see if it locks up.

I would check their websites for the newest drivers. CD drivers that come with your purchase are usually out of date (even on new equipment) after about 6 months. So unless you have a super new build or component, more than likely there are newer drivers out there. I would still try what i suggested in seeing WHICH driver is causing the issue. Once you find that out then I would reinstall that driver from the manufacturers website driver - not from the CD.

 

[philbar71]

yes i intend to do that but were not so shure it's a driver. i'm leaning towards it being the antivirus software, trend micro, so i will try running the pc without the anti virus

 

[Lexluethar]

I doubt the AV is causing the lockup - and I wouldn't run the computer w/o AV, at least try another AV software.

I have had AVG cause problems on one computer. Also, have you installed all the windows updates and service pack 1? Was your OS Vista Home Premium with SP1 included? There have been some known issues when installing 4GB of RAM even on 64-bit Vista, but an update that is included with SP1 fixes that.

Otherwise, it sounds like it could be your video or sound driver that is at fault. Open up your Device Manager and make sure no drivers are listed with yellow question marks. Then if nothing is indicated, I would start by uninstalling the video driver and getting the latest off of the manufacturer's website. Make sure it is 64-bit Vista driver. If that doesn't fix anything, try the sound driver, same method.

EDIT: Oh and was that BIOS update a beta version or final version driver? If it was a beta version, I would flash back to the next most recent BIOS version and see if that clear's things up.

 

[philbar71]

oops i for got to mention it's ultimate 64 bit with sp1 and that was the latest version not a beta version.

 

[philbar71]

well this thread has kindve died off. but we installed 32-bit and put only 4 gb of ram and havent had a lockup since. so it some incompatibility or what i wonder?

no edit button for previous post. why not?

My Asrock MB underclocks the FSB by 5% with quad core cpus. Not that would be an issue with your setup, but that might be something to consider if you ever try the 64 bit version again.
