Okay. I've been regularly running two different virus programs, Panda Titanium 2007 and Trend Micro Housecall. I've also been regularly scanning with Ad-Aware.

Something got through. The problem doesn't happen all the time but it's consistent enough that I finally realized it wasn't just a random computer hiccup.

Sometimes when I try to open My Computer, My Documents or any related action or try to run a search, the computer pauses. Then everything -- all the icons on my desktop and the entire Windows Start Bar -- vanishes. It lasts a couple of seconds then everything comes back, no problems. Any other programs I was running are still there and working fine. But my folder hasn't come up or my search is gone. This has even affected CTRL+ALT+DEL.

I've d/led and scanned with SpyBot. I'm not sure how much it fixed. The problem seemed to have gone away but now it's definitely back.

It seems to have come down a couple of months ago when I d/led an updated to Trillian.

Here's my Hijack This log:

I'm seriously thinking of just backing up and reformatting. We've tried to apply some of the solutions I've seen elsewhere on this forum but, among other things, we can't seem to get the computer to boot in Safe Mode.
I would greatly appreciate any help.

For a one-off restart into Safe Mode go Start, run, enter msconfig; under Boot.ini tab check /Safeboot, Apply, Close, select Restart.
You could run this to give us a look at recent files and a few other settings..
==Download this file to your desktop: http://download.bleepingcomputer.com/sUBs/ComboFix.exe
- to run it dclick combofix.exe and follow the prompts to start it. When finished, it will produce a log, C:\Combofix.txt - post that log in your next reply.
A word of caution - do not touch your mouse/keyboard until the scan has completed. The scan will temporarily disable your desktop, and if interrupted may leave your desktop disabled. If this occurs reboot to restore the desktop.
Other than that it appears that some registrations have been corrupted; I would try a Repair of Windows via the Setup on your installation CD.

Thank you for helping me. ^_^
I tried the repair option from my Windows Installation CD but I think it requires more computer knowledge than I have. I got as far as the command prompt but I had no idea where to go from there.

Ah, a common misinterpretation of Microsoft's options, Heather - you entered Recovery Console, and you don't want that.
At that point in the process instead of typing R press Enter to start Windows Setup [Repair is a mini version of installation]
=> To setup Windows XP now, press Enter.
Next comes the license agreement, you will then be presented with a list of installations to choose from to repair [usually just the one installation...]. Select your installation and type R. If Repair is not shown as an option then exit Setup, DO NOT "continue to install a fresh copy without repairing" or you will lose data and applications.
Setup will copy files etc and then reboot your computer. Don't boot again from the CD by pressing any key when the message appears, just wait a moment and your machine will restart.
Enable your firewall [ or windows firewall is sufficient at this time] and validate your XP.
Say how you get on.

I ran the Windows Repair thing like you said (thank you for clearing that up for me) but the problem's still there. I clicked on "Control Panel" so I could remove my husband's account from the computer (since he doesn't use mine anymore) and again everything but the background vanished and came back and Control Panel never opened.

Heather, a windows Repair replaces windows files and restores its registry settings, third party software files and reg entries are not affected so I think the problem may lie in that direction....
Because you mention Trillian it may be worth searching for and deleting these two WildTangent files which may have been installed along with Trilllian [bundled "spyware"]:
wtcpl.dll and wtcpl.cpl
May work, may not. The Repair was worth a try, at least it pointed the search in another direction.
Does going Start, run, typing control and pressing Enter work?

I just tried "Start, run, control" and it didn't work. The Start bar flashed again, which also means I can't run search and delete anything. If this happened every time I'd've figured out that something was wrong months ago but sometimes it does and sometimes it doesn't. Rebooting doesn't necessarily give me a boot where it works.

Yes Repair was worth a try. It's good to know where the problem isn't; especially when you can't find where it is. Thank you. :)

I know that you have Panda AV, but it may pay to try one of these. Theory is that it is possible that your resident AV could be affected by any malware, whereas an online scan will not be. First clean:
==Download this temp file cleaner from http://www.atribune.org/ccount/click.php?id=1 --click in the download window to run it, and when ATF Cleaner opens go Select all, and then Empty Selected.
Next click Firefox [if you have that browser..] at the top, Select All again, and Empty Selected again. Follow that procedure also if you have Opera.
Close ATF.
Just in case:
==AVG AntiRootkit from http://free.grisoft.com/doc/5390/lng/us/tpl/v5
One of these two:
==Pandasoftware ActiveScan using IE only from http://www.pandasoftware.com/products/activescan? - just follow through the pages, supply a "valid" email address... To reduce the number of detections run either CCleaner or ATF cleaner first [to remove cookies].
==Kaspersky Online Scan, from http://www.kaspersky.com/virusscanner -press the Kaspersky Online Scanner button, follow through....
Sorry I cannot help further.
