Windows xp boots but the desktop will not come up

Have you changed something. It sounds like you have lost your config files. With out proper software or boot disk you will need help

easiest way is re install your operating system,or use another computer to find the boot manager for your hard drive.put it on a floppy disk.press f8 as you start your thinkcenter ,select floppy as first boot device.restart with floppy in the drive,

press f12 on boot to select what you boot from. Also, make sure the CD is actually bootable.

How about this, Boot to safe mode with Networking. Download MALWAREBYTES at : http://www.filehippo.com/download_malwarebytes_anti_malware/ Run a FULL SCAN, Delete ALL results, reboot. ALSO, run YOUR UP-TO-DATE Anti Virus, a Full Scan.

it seems as they are conflicting this u usually caused by jumper settings you need to download the utility program from the hdd manufacture the utility allows you to change hdd priority you need to change the settings on the second hdd to slave and the first hdd to master but like i said unlike ide which has jumpers sata has digital jumpers the utility from products website is needed for this

Sorry, Windows is corrupted beyond repair (you probably have a very nasty malware infection). A fresh full install is mandatory.
And next time use a better antivirus.

well there is a couple of thing you could try 1) power on your computer press F8 rapidly and select "last known good configuration" 2) power on your computer press F8 rapidly and select safe mode login with your account and press yes to restore you computer to an earlier time select a date tah the computer worked ok and click on restore
try it and please if you have any problem please comment

Is it possible that you have installed winxp twice? You say that you installed XP Pro sp3 was that an upgrade from xp home? if so then you will need to uninstall one or both versions of XP then install only one.. Make sure you backup any important files first though

This may be because you have the wrong drivers installed- i reccomend starting your computer up in safe mode and using system restore go back to a past restore point before upgrading to SP3

then update your drivers before upgrading to SP3
i reccomend drivermax.com to update drivers.

Hope i could help

Comment if you need more assistance

I had the same problem with an Intellistation 6868 for years. It just wouldn't load XP but ran fine on Windows 2000 SP4. I tried 3 different XP Installation CD's with no luck. After several attempts at installing XP I bought a clean XP Upgrade from ebay.

It took me 3 goes to install it but eventually I got it in there. If you can get XP to start on the 6868 press F8 and start it in safe mode first then when it's booted fully, shut it down and and then start it clean again. It worked for me. I've been running it for 5 months now and it's fine.

I couldn't get it to work at all on the 6868's onboard IDE so I installed a PCI Raid Card and it boots fine on that.
