Upgraded my dell from d820 to d935 very unstable

Did you do all of the updates at the same time? If not, what order and time between. Did you experience the problem only after the last upgrade?

the problems started after the processor upgrade the last one before that was the video card and psu, and everything worked fine. It wasn't until I installed the new cpu that these problems started, now in media center it no longer freezes it just tells me that files need to play video and audio could not be found or not working correctly. I don't understand why changing the processor would cause software problems but then again I am not a professional. Don't know if it matters but I got curious and wanted to see if itunes would play audio and video and it does but it told me my computer was not authorized and I had to authorize never had it do that before, I wondered if changing my cpu would deactivate my cd-key not sure how many upgrades uncle billy allows in vista but it didn't deactivate so I guess I'm good. If doing a clean install would help I'd do it but I can't find my copy of home premium only home basic upgrade.

Well everything is working fine now. I kinda knew i'd have to but really didn't want to, I did a clean install of vista and now everything is ok. I knew in the first place that normally when you upgrade, cpu's, and mobos, you need to reinstall the OS. I guess i was just hoping to be one of the lucky few who have been able to do so with no problems.

I dont have a dell i have an HP. But i just ordered a Pentium D 920. I have never had to reinstall after CPU swaps. I am on XP. XP is usually a little easier no drivers. He changed a lot at once, i am only swapping the cpu. I have swapped everything else over the last couple of months.

If i have to do a reinstall i will order a new mobo and go ahead and get rid of the HP mobo all together. I already have a new case and the rest of the PC componants are all new so i can just swap them into the new case.

thanks

The mobo is 3 years old. The old HP site said up to PD 8xx up to 3.2G. The HP spec site hasn't been updated in 2 years. So, i emailed HP customer support to get updated specs. HP support specifically said that my mobo WOULD support a PD 920. They also said it would NOT support the new Core 2 architecture. So, i went with the 920. I was happy to atleast get to put in 65nm architecture. If i was stuck with PD 8xx i would have waited.

HP support supplied a link to the latest Bios, as well. I have also contacted Pheonix/Award Bios. They linked me to a site that scanned my system and they are looking for a better bios. I am hoping they can unlock my bios for OCing. Probably not, but it is worth a shot.

The mobo has the Intel 945G/GZ express chipset. The intel site states that 945G/GZ will support Pentium 4, D 8xx, D 9xx, dual core and Core 2 Duo.

The PD 920 will be a decent overclocker when i get my new mobo. It should last me at least another year before i need to spend the bank on a quad. Maybe by then the new 45nm quads will be out. I don't plan on waiting so long to upgrade my CPU again. I am looking at an X38 asus mobo that will support the PD 920 up to the new 45nm chips 800-1333 FSB, PCIe 2.0 etc. Hopefully it is under $200 when i am ready to buy it.

I have all the latest drivers, so i am hoping for an easy swap.

I will stop now, I did not mean to hijack jimmyrigs thread.

thanks
