I'm new to this forum and I want to say hi and thanks for such a wonderful site. I'm not sure anyone can help with this problem but I'm at my wit's end.
First, my system was made in 1991 but I have upgraded many components. I have an ASUS A7M266-D mobo and 2 gigs of Crucial RAM in 4 slots. I have 2 Athlon 2600+ MP processors and temps run 48-50 degrees (I constantly monitor the temps). No overclocking of anything. I have 2 new hard drives (7200/8mb cache), a new nVidia 6800 256MB graphics card. I'm running XP SP2 and it is all up to date on windows updates. I use NOD32 as my virus scanner and regularly run AdAware and Spybot Search and Destroy. I clean dust from inside the machine regularly with compressed air. I defrag every day with DiskKeeper and regularly scan for viri. My machine is on 24/7 and is used mostly for graphics work but also some email and web browsing. I backup with Acronis True Image to a 300G Seagate HD attached to a USB 2.0 card (since the USB 2 was not functional on these boards when purchased). The USB card is ASUS USB2-PCI 4 port card.
Ok, now the problem…
For 4 years everything was great. Suddenly my USB speeds dropped. DiskSpeed32 shows that speeds went from 28MB/sec to 4.5MB/sec. I can't figure out why. I have 3 external drives and tried it with all of them. Same speed. The drives also use Firewire and when hooked up as Firewire they run at 28MB/sec. So the problem is not the drive, must be the computer. If I boot from a CD and use the USB drive to restore files I get full speed. So it must be software, not hardware. I see no errors about this in the log. I have searched the net and Microsoft's Knowledge Base and can't find the answer.
1) I tried removing the USB drivers and having windows reinstall them. No change.
2) I tried manually updating the USB drivers. No change.
3) I downloaded the latest drives from the ASUS web site and there was no change in speed (but some of my devices didn't work so I went back to the windows drivers).
4) I tried all 4 USB ports but they are all the same speed.
5) I tried a different USB 2 cable. No change.
6) I went to the hardware device manager and removed EVERYTHING with USB, unplugged all devices, reinstalled the drivers after rebooting, and plugged in ONLY the drive. No change.
7) I used 3 separate tools to clean the registry, still no change. (Registry Mechanic, RegVac, and CRC-Complete Registry Cleaner).
It's got to be a software problem since Acronis True Image can restore backups at full speed when I boot from the freshly made Acronis Boot CD, but for the life of me I can't figure it out.
Now just to throw this in there since it might be related, but recently shutdown has been VERY slow. It quickly closes all programs, saves my settings, and then says, “Windows is shutting down.” Then it hangs for 50 seconds. Eventually it closes. When I check the logs sometimes it says …
Event Type: Warning
Event Source: Userenv
Event Category: None
Event ID: 1517

User: NT AUTHORITY\SYSTEM
Computer: VOODOO
Description:
Windows saved user VOODOO\Ed registry while an application or service was still using the registry during log off. The memory used by the user's registry has not been freed. The registry will be unloaded when it is no longer in use.
This is often caused by services running as a user account, try configuring the services to run in either the LocalService or NetworkService account.
So I went to Microsoft’s site and downloaded and installed UPHclean. After installed the log says…
The following handles in user profile hive VOODOO\Ed (S-1-5-21-2027339946-1729697498-769079328-1004) have been closed because they were preventing the profile from unloading successfully:
svchost.exe (1228)
HKCU (0x258)
… but I don’t know what that means.
Sorry to be so long winded but I wanted to give you as much info as I could. Thanks so much for any help you can offer.
