I have had a reoccurring problem for the last 4 weeks (on a 2-year old XP Pro install).
Everyday, I book up around 9am. I use the computer all day (Outlook 2003, Firefox, Word). Then, around 4:30pm or 5pm, I start getting a bunch of "Windows Delayed Write Failed" error messages, pointing to various files (Firefox temp files, Windows temp files, network cache files etc.). If I click through these, they keep appearing for different files. So I either Shut Down cleanly, or have to pull the plug.
After rebooting, I then get an error message saying the BIOS can't find the OS on the hard drive. But if I power down for about 20 or 30 minutes, it boots back up fine and I'm good for another 8 hours. It's very, very weird.
Here's the details:
-MSI 945PL Motherboard (MS-7236) Intel ICH7 Chipset
-Intel C2D 6600 CPU
-2GB RAM (Patriot 667)
-WD Caviar Black 500GB Hard Drive (Replaced a Velociraptor 300GB drive when I thought that might be the problem)
- Windows XP Pro SP3 (on a Domain w/ SBS 2003)
I've done System File Check and it didn't fix it.
