Default Computer Gurus your help is needed.

I have a old model optiplex 745 mini tower which still uses an ancient Pentium D processor. i currently have windows vista loaded on my HD

My friend recently gave me his optiplex 755 mini tower which is an identical system but uses a intel duo core 2 chip. i tried to basically just swap out my HD and rams and move the items over since i thought it would be a direct swap but i was wrong. the old system and HD was using XP.

when i installed my HD i get a continuous reboot once the windows green scroll bar part comes up and it prompts me that it was unsuccessfully started windows.tried using safe mode, prompt mode etc etc and no go. I updated/flashed the bios and updated the chipset driver to the newest and still receiving the same error message. i then swapped my old HD back to my previous 745 and it started up like nothing was wrong.

any idea of how i can get this thing started? i have alot of work information on my old HD that i cannot afford to erase, do i need to reinstall windows vista on the HD for it to work?

Thanks.

HD's are not inter-changeable unless the chipset and version of windows on the pc are identical. You'll have to reimage the 755 to vista then use an external hdd to move tghe files over to the new system.

That's not true at all. It's dependent on the operating system. Windows 7 is capable of going from system to system and it automatically updates itself to be compliant with that system. How would I know? I somewhat recently sold my mammoth PC to a member on here. Instead of buying new HDD's I took the ones I had already with Windows 7 on them and swapped them over to my new build. Booted up without a hitch, 7 noticed it needed some new drivers, downloaded them, and all was well.

I know XP has the issue of being hardware compliant and that even changing out a bunch of parts in a PC will make it throw a fit. I'm not as sure about Vista however, figured they would've done the migration thing a bit better.

I agree that Windows 7 is interchangeable, but not always. I had a perfectly good laptop HD that had Win 7 Home Premium on it and swapped it into my brothers laptop to try and get it running, but no dice. I had to move the data off the HD, and do a fresh install on his laptop. I've done the same with a Win 7 Pro HD twice before though with success, but i doubt it has anything to do with Home Premium vs Pro.

Anyways with a new PC i always like to start with a fresh install Back the data off, format it clean and reinstall Windows on it. Then only put the data you actually need back onto the PC. lol

I'll attest to this 100%. Mine boots up slower now than it did on the OLD tower. Need a fresh install ASAP. And if you do a clean install it'll run better as you won't have the PC filled up with temp files and other junk clogging up your folders.

Just make the other HDD as a secondary/slave. Access and copy the data onto the existing drive and you are ok.

optiplex 745 uses the intel 965 chipset. optiplex 755 uses the intel Q35 chipset.

different chipsets, different drivers.

another "trick" might be to swap processors if you're technically-capable. assuming that both motherboards can handle different FSB speeds (1066 mHz for some C2D chips vs. 800 mHz Pentium D chips), the both processsors are of the same socket size.

Old system: optiplex 745, pentium D, single core processor, vista (or xp)..ambiguous
New system: optiplex 755, dual core processor, vista

It appears the goal is to upgrade to the dual core processor machine while retaining your old data from your old machine. Is it only data or are applications also involved?

If it is data only, plug the HD from the 745 into the 755 and make it a slave HD. You will have all your data with you, but not the applications.
