I recently upgraded from a Athlon 64 3200+ to an X2 4200+ and it came in today, I got it all installed perfectly, started the computer up and everything was working fine. It got to the point where the Windows XP screen would COME on, and then it just flat out shut down. At this point, pressing the button to turn my computer on wouldn't even work anymore. I had to reset the power supply. I pulled everything out and put it back in to no avail. I eventually re-installed the 3200+ and that's where I'm at now. Any advice is appreciated.

Remove all traces of thermal compound and then add a nice NEW small flat layer of that wonderful stuff ...... always USING a nice plastic credit card , stick it back in your socket and boot up....

I find to much or to little can cause this ... same things happened to me ..... Repair install of XP

When changing major components such as a MBoard or CPU XP will sometimes balk as the ORIGINAL install ties itself to the HARDWARE it was installed on...
I recommend reading it thru thoroughly before hand and printing it out for reference...
If done properly you will retain all programs and data but it's advisable to backup the most important stuff ahead of time.

Good Luck and let us know...Thanks for the advice so far.

Patio, actually I threw in the boot disc to see if I could at least reformat and it still did the same thing.The procedure doesn't involve a format...it's designed to save your data and the OS intact.
If you're saying it is still shutting down before you can do anything then i would re-check all your hardware connections...etc. and make sure the CPU/Heatsink combo is seated firmly.
Did you have to remove the MBoard to do this process ? ?
How old is the PSU ? ?
Is the RAM seated properly ? ?
In other words re-check everything to be sure...Thanks guys for taking the time to read my problem and reply. I cleaned off all of the paste and re-applied it. It works now AND on top of that my computer recognizes both gigs of RAM (see my other thread)!!!Quote from: casualfitzy on September 27, 2007, 08:19:12 PM
