Hi, im new to this forum and I had a question about some new hardware... I recently installed a new pentium 4 3.0ghz processor a new asus P5ND2-SLI MOTHERBOARD and new ddr2 memory and since my old motherboard had an AGP slot and the new one is PCI Express I had to switch from a ATI Radeon X1300 AGP graphics card to a ATI Radeon X1300 PCI Express graphics card... once everything was installed im having trouble... it'll get to the WindowsXP loading screen then shut off and restart and do the same thing and keep doing it. A friend of mine was having the same trouble when they added a new processor and motherboard awhile back and they've GOT it fixed but i'm UNABLE to contact them right now so I was wondering if any of you knew what the problem was... ThanksDid you reinstall Windows after the new hardware was added?no, Windows is still installed it'll just get to the loading screen that pops up before you choose your user and just shut off and restart immediatelyIf you installed Windows with completely different hardware than what you are expecting it to run on you should not be surprised that it fails.

Some people try a repair install, but if it were me I would format the drive and reinstall Windows, without a doubt, every time.
The point being that u should format ur HDD segment that u have Windows installed on. Im going to do this very soon (once i choose with GFX card to buy) while installing a new motherboard. You must erase one segment of ur HDD (if ur HDD is seperated into SEGMENTS, such as C: and D: or more) and then u can install Windows again.

I will however try and re-install the new drivers of the new hardware and see if that does the TRICK because its possible that it will, but if it wont then its best to re-install Windows.Hey, just want to thank you guys for the help, I re-installed windows now im up and running with the new upgrades thanks alot!Glad you are all fixed up, and thanks for posting back. A good format and reinstall solves all Windows problems, for a while.
