Was it connected to the internet after the install?
Here's a note about that...
Before the install/reinstallation of Windows XP, I highly recommend that you download Service Pack 2 "for multiple computers" and burn it onto a CD. The download is approximately 272MB. If you choose not to do this step, your system could become infected with a virus or worm exploiting the vulnerabilities that Service Pack 2 fixes. I also recommend that you do NOT have your system connected to the Internet until after the installation of Service Pack 2. This means that you cannot activate your XP installation during setup, but you can accomplish that task following a reboot after Service Pack 2 is installed"
The terrible truth is that XP will be invaded if it's a stock XP install. Even a LAN connection can supply a path for the worms.
Missing from your post is if the BIOS is current, how much RAM and MOTHERBOARD drivers...
Bought XP Home to put on an older pc. Put the CD in and it began loading files then I got a very long error message:
A Problem has been detected and windows has been shut down to prevent damage to your computer.
If this is the first time you've seen this stop error screen, restart your computer. If this screen appears again, follow these steps:
Check to make sure any new hardware or software is properly installed. If this is a new insallation, ask your hardware or software manufacturer for any windows updates you might need.
If problems continue disable or remove any newly installed hardware or software. Disable BIOS memory options such as caching or shadowing. If you need to use safe mode to remove or disable components, restart your computer, press F8 to select Advanced Startup options, then select Safe Mode.
The system(AMD Athlon 1.33Ghz,512DDR ram,asus mobo)along with a Creative 5X DVD Rom and a Lite-on DVD Burner were hardware that was laying around the house, except for the burner which is new, so I put it together to play with XP. My main pc is still using Win98SE. I wasn't sure how to update software that was still to be installed, so I disabled the L1 and L2 caching in the bios. I also disabled the DVD burner, physicaly and in the bios. That allowed me to install after it formated my HD to NTFS. The install was very slow. It took about 12 hrs on my 40g WD HD. After install, the pc runs SLOW. And applications open very slow. Almost 1 full min. to open Device Manager. It takes 5 min. by my clock from pushing the power button until desktop is completely loaded. I,ve tried enabling the caching but the pc just reboots right after the XP screen. I was able to change the drivers for my network card(not connected to the web) and install the latest drivers for my vid card, so it appears the OS is working OK, just very slow. Any ideas what I could do to fix this?
