Hi all, I hope someone might be able to help. I have next to me an HP 8100 Elite SFF, running Windows XP 32-bit. It's just over a year old, just out of warranty, and has developed a fault seemingly out of nowhere. The PC is used to perform file transfers in our business using a lightweight bespoke client, which is working just fine. However, having worked flawlessly for a long while it has developed a startup fault out of nowhere. When booting Windows, there is a delay of several minutes between the loading screen and the eventual appearance of the desktop. There are no errors in Event Viewer, and Device Manager is reporting all of the hardware as working correctly. There is nothing plugged in other than mouse/keyboard/ethernet cable/monitor, and no hardware or software was changed prior to the fault developing. We have swapped out all cables etc and run a full defrag to no avail. Any other options or wipe and start again? A fix is preferable to a reinstall.
