Upgrade

[randywill]

I've just upgraded a system that I built a few years ago.  The system, a ASUS skt 754 K8N with a AMD 64 3000 CPU.  I upgraded the CPU to a AMD 64 3200.  The system would post, but would not load XP OS and keep rebooting and posting with no errors on post.
I tried a repair or reinstall with the XP disk, it would get part way through and the system would reboot.  I checked the BIOS settings, setting any overvolts or overclocks back to default.  The BIOS shows all hardware correctly. 
The AMD 64 3200 CPU was manufacured about the same time as the AMD 64 3000 CPU that I replaced.  I'm against flashing the BIOS, as this solution has, unfortunately, rendered several MBs useless in the past.
If I can't get it to work, I guess that I would drop the other CPU back in and forget about upgrading the CPU.
Any ideas?

Hi Randy and welcome to puterhope !!

  Had you ever replaced THAT cpu before and do you feel confident that everything "snapped" back into place ok and the heatsink / fan  & thermal  paste / strips are all ok ?  Any heat issues inside that case ? Did anything else possibly occcur to the puter when upgrading ? Windows working ok , just  before replacing the chip ?
You could take the battery out for 30 seconds and that would insure the default settings are restored?

Yes, everything went back together just fine.  I had checked the temps when I was in the BIOS, core temp-40 C.
I will take out the battery and reset the CMOS and see if that cures it.  When I do, I will let you know if that works.
Thanks for your reply.

Okay, I took the battery out and reset the CMOS.  I rebooted and XP still will not load.  I keep getting the screen that prompts me to either start in safe mode or start normally.  I've tried both ways, but it just keeps looping back to this screen.  Anybody have other ideas what might be going on here.

Did you remember the thermal compound for the CPU ? ?

Just going from AMD 64 3000 to AMD 64 3200 is not much of an upgrade, is it?

Medieval Tech Support rocks....! !

LOL.  I swear I could watch that video a hundred times and still laugh.

Okay, I guess that's it for computer hope forum. Thanks to honvetops for your ideas, if you have any other ideas, I might check back.

A very common thing when upgrading the CPU is that the power supply is pushed over the limit, especially if it is a cheaper model that was already at the edge before. I note that you did not mention the wattage or maker of your psu. If this is because you did not consider it worth thinking about, maybe this could be a possible thing to check out?

I am surprised nobody has suggested this.

Those reboots sure sound like my AMD upgrade frustrations, which were cured by a decent branded power supply to replace the no-name one I had that came with the $40 case I purchased... (a lesson learned there, I can tell you!)

You could try reducing the load somewhat by only having a minimal hardware config - onboard graphics (if available) rather than GFX card, hard drive only, (my psu used to quit as the DVD drive spun up) and see if she boots OK, in that case your PSU would definitely be implicated, but even if such a test did not remove the reboots, I might still suspect the PSU. maybe some data about it would be a useful thing to post?

 good info & relevant post   ^   thanks

Thank you for your kind words, honvetops 

Another thing I could add is that sometimes a cheap power supply will degrade over time, say one to three years. Some ultra-cheap designs seem as if they are intended to barely get the computer system through a 1 year warranty period...

Having read your posts and having built 2 puters myself,  it IS amazing what companies will throw inside a "new"  case and describe it as a  psu !!!

I have 3 brand new ones in my attic,  maybe we should raffle them off to the next person who wants to  oc  a celeron chip to like 5.0

the psu is the poor cousin at the feast very often, at least until the first cpu upgrade...

Many people will eagerly specify RAM, CPU, graphics card, HDD, burner drive, etc, and then put those items into the cheapest case they can find with a PSU included, and then they wonder why it is unstable.

I rarely  use a power supply that comes with a case for that reason.  I didn't consider the power supply, since I haven't added anything extra.  I have one hard drive, one DVD/CD combo writer and four fans with a Enermax 480W PSU.  I did check the voltages from the PSU and also the core temps in the BIOS.  The processor and all hardware was recognized in the BIOS.  Everything checked out fine in the BIOS, I reset the BIOS, taking the battery out and moving the jumper.
