Computer Won't boot after upgrade: AMD 3000+ --> AMD X2 Dual Core 4

[mic]

I just popped in my new AMD Athlon 64 X2 Dual-Core chip and windows does not boot up anymore. The windows splash screen loads up but suddenly my computer reboots on it's own. I have tried to reinstall windows but that fails too. When I boot from my XP cd, I get a blue screen telling me that I have a hardware or software problem. It also says to try turning off the bios cache and shadowing.

 

I'm pretty much stuck here since I cannot load or reinstall windows. Does anyone here have any suggestions?

First run memtest from bios. Second think about better PSU. Also must have 623 bios or later for dual core.

Go back to the basics. Run Memtest #5 and #8, 8-10 passes and then the complete test for a minimum of 4-6 hours. New processor means a new memory controller. It may not like your timings.

reinstall windows (2 cores now)

Thanks for the quick replies! I'm first going to update my bios and see if that works. If not, I will run memtest. I hope I have some luck flashing my bios without windows.

 

^ ISSA2000, my computer crashes when I try to reinstall or repair windows.

You defently don't need Windows to flash ur Bios ,always flash from Boot either with a Floppy

or a Boot CD ,Windows Flash is not recommended.Try do a search here for Tmod Bios Cd it will do the job for you....I has the feeling that your PSU is a little week maybe , a 4800 x2 takes some juice compared to a 3000+ ..

If windows is not stable -- DO NOT USE WINDOWS TO UPDATE YOUR BIOS! (Probably not a good idea in any circumstances).

 

If you have not yet, clear your CMOS, reload optimized defaults and save, reboot back into the BIOS, change what needs changing and save again -- don't use or start with any saved settings.

 

You probably don't need to reinstall. Do a repair install. I've done that for 754->939->939x2, VIA chipset -> SIS -> nVidia, various MBs, changing my boot device from IDE->raid add-in card, etc.

 

To do this, make sure your install disk is up to the lastest fixpak (google how to slipstream it). Then boot from it and start the install. Close to the beginning, it'll scan your disks for existing isntalls. It'll find yours and ask if you want to repair or reinstall. Highlight the existing install and tell it to repair. ALWAYS backup your system/important files 1st!!!

I finally had some time today to work on my computer and I got itworking in no time at all! I flashed my bios to 6/23-3 and ran memtest without errors. I restarted after checking over a few bios settings and windows booted without a problem. I was expecting windows to still only utilize only one core but I see both cores running on the task manager! Thanks for your replies guys!!

Glad you got it running! I'm hoping to be installing my 4800 x2 next week in my soon to be ordered UT Expert.

Remember to install the AMD Dual Core Optimizer.

and you can check each core speed with the AMD Clock Version 2.0.1

For some strange reason, windows seems a bit laggy at times after I installed the 4800 x2.

I have installed the AMD dual core optimizer and it made no difference. I'm due for a fresh installation of windows xp anyways so I think I might just start over and go from there. I will also be adding a 600watt power supply and maybe another 1gig of ram. Time for some overclocking!!

mic,

 

I can tell you from personal experience, that a Windows reinstallation is not absolutely needed when swapping from a single core to dual core processor. It is advisible to do so, but not absolutely necessary assuming you followed the correct swap procedure.

 

Did you install the AMD Dual Core Driver also?

[davidk21770]

What I did was backup and run a repair install.

I've done that for 754->939->939x2, VIA chipset -> SIS -> nVidia, various MBs, changing my boot device from IDE->raid add-in card, etc.

 

 

To do a repair install, first make sure your install disk is up to the lastest fixpak (if it's not that way already) -- google how to slipstream it. Boot to windows, put the CD in and start it (if it doesn't autostart). Start the install. At some point, it will scan your system for current windows installs, find yours, and ask if you want a new install or to repair an existing install. Highlight your current install and tell it to repair. ALWAYS backup your important files 1st!!! (I do a complete backup!)

 

Another thing to check is that your boot line in boot.ini has /usepmtimer on it.
