Numerous "warnings" in Event Viewer (WinXP)

WinXP Media Center Edition SP3 - there are numerous "warnings" in the Event Viewer in the 'System' section. Each time the warning shows up (about every 2-4 days), there will be at least 5-6 in a row, sometimes as many as 15 all in group. Here's the message (a screen shot is attached below also):

The owner of the PC is convinced the new hard drive I installed about a year ago is failing because he'd get occasional BSOD crashes, but I ran 2 different diagnostics on the drive, and both passed 100% (one was the Seagate 'Seatools' bootable diagnostic; it's a Seagate 320gb SATA drive). The system passed an extended RAM diagnostic (I knew the RAM was OK, but I ran the test just to be thorough). I'm researching the message right now, but haven't found much.... any thoughts?

Thanks!

(I've been using the PC for about 6 hours now w/o any problems, but then again, the warnings don't necessarily show up every day; sometimes there's 4-5 days with no warnings)

 

Upon looking at the Event Viewer messages a bit closer, I found that there's a few of these identical warnings that refer to "\Device\Harddisk1\D" but the vast majority refer to HD0\D. There is only one hard drive in the PC.....
:confused

EDIT - a bit more digging, and I discovered that the "iPod Service has entered the running state" occurs about 40sec before a string of the warnings starts; the iPod service is not listed right before the warnings every time, but it is on all but 2 out of a total of 12 or 13 'runs' of the paging warnings.... a connection between the iPod and the paging problems?

 

Oooops. I over-estimated the number of the 'runs' or 'groups' of the paging warnings. There's a total of about 6 groups. The iPod service starts immediately before 3 of the warning groups. Harddisk1 is refered to in a total of 4 warnings (there are probably 30 warnings total split among 5 or 6 groups of warnings; one group has only 3 warnings, one group has about 15, the rest have between 5 and 8 warnings in each group).

I'm running chkdsk c: /r right now. It may not make a difference, but it can't hurt....

I'm studying KB244780 right now.... hopefully it will help...

 

I spoke to the client, and he gave me some more info. I hadn't experienced any problems, then he told me that the PC will BSOD and reboot mainly when several windows are open and active. I launched the default browser (Safari) and opened 3 or 4 pages, I started a MalwareBytes scan, I launched IE8 and had several pages open, then started playing Solitaire. Yeah, not really a huge load, but after about 10min of this, the PC spontaneously rebooted w/o warning, no BSOD. The next thing I know, I was looking at the Dell POST logo, followed immediately by the message "Primary Hard Disk 0 not found; press F1 to continue, F2 for Setup". Since I'm "officially" off work for the weekend, I simply powered off so any Event Logs will remain intact and "fresh" for Monday morning, but I'd really like some input on this. I'm wondering if Safari was removed, would that solve the problem (after all, the iPod service tends to start immediately before a paging warning; I know that the iPod service and Safari are competely different and independent, but they are both from Apple). The HD passed every test I threw at it, so did the RAM. I have not tested the PSU, nor have I looked closely at the MB.... that's for Monday.
