I made a post in the HijackThis! portion of the forum that had a HJT log in it, but the more I see out of this computer, the more I think it isn't related to spyware/adware.

I came home yesterday afternoon to find my computer frozen at the login screen. My sister was logged on, but the screensaver shows the welcome screen after a period of time (like the screensaver goes away, it turns the monitor back on, and the welcome screen pops up; but that's another problem, not worried about it right now though). So the computer was at the welcome screen and frozen solid. CRTL + ALT + DEL failed, so a reset button was my only option.

So it restarted like normal, and just before the welcome screen showed, everything stopped and it froze. I reset again, same result. So I booted into Safe Mode (works every time), ran virus scans, adware scans, etc. Nothing serious showed. So I rebooted. This time it made it to the login screen fine, but to be on the safe side, I tried again. It locked up.

I repeated this procedure to get back to windows normal mode and ran the HJT scan and posted it. I'm still waiting to hear about that. Then I played with it some more, restarting and such, finding it okay. So I booted into normal mode and signed my sister back on. I came back about 40 minutes later to find it frozen again, and reset was only option.

Then this morning (after I'd turned off the thing in frustration), my mom needed to use it to pay a bill. I told her it was a futile attempt, as I figured it'd freeze at login again. It booted fine. So far as I can see, it freezes whenever it jolly-well pleases. I'm not sure where to go from here.

As I said, I ran virus scans and adware scans and found nothing. It's also up to date as of last weekend (with exception of SP2). And I suppose I should mention that it's a Windows XP Professional machine, custom built by me about 4 years ago.

If anyone can shed any light on this problem, I'd be appreciative.

Hello street9009 and welcome to BC.

Have you been inside the case to clean out the dust build up lately? What kind of temperatures are your CPU, Motherboard etc running at.

Go to Start>Run and type in msconfig. Under the Startup tab, compare the programs loading at startup with our Startup Database found at the top of this page and disable what you can. Based on your HiJack This log there are a few you don't need.

You should receive a reply to your log in the next 12-18 hours. Please don't post back into that thread as you will be moved to the back of the line based on the time of your post.

According to the CMOS, the CPU temp is 46C and the System temp is 27C. Seeing as the CPU will run in lots hotter, I doubt temperature is the problem.

It's much too constant for it to be a temperature problem, I think. When it locks up on startup, you can almost time it to the millesecond. Now, here's another interesting tidbit of information. The computer was still on from this morning where my mom paid her bill online. Still running fine. I started a virus scan, and it detected 3 (I think on the secondary drive though I can't be sure), but was locked up when I came back to check on it. This time, however, the reset actually worked and the logon screen came up perfectly.

So a random occurance with some similarities? Sounds kinda like it.

I'll wait for a response to my log and then go from there.

Thanks.

CWShredder
CW Shredder removes some variants of spyware known as the Coolwebsearch Trojan.

"warez") sites. Run CWShredder after installing, and have it look for updates. Then click the "Fix" button, and the program will both scan and fix any problems it finds. If your system does not have this kind of spyware, it will give you the good news.

I try to, but it locks up on scan. Working on it though. And I have Spybot, Adaware, Microsoft Antispyware, and Norton AV 2005. Thanks for the suggestions though.

Something else interesting: I booted back into safe mode and scanned for viruses, found nothing. I have never seen anything behave so strangely...

Look in Device manager for any problem Devices.

Look in Event Viewer for a log of the freeze ups.

How to View Event Details

To view the details of an event, follow these steps: 1. Click Start, and then click Control Panel. Click Performance and Maintenance, then click Administrative Tools, and then double-click Computer Management. Or, open the MMC containing the Event Viewer snap-in.

2. In the console tree, expand Event Viewer, and then click the log that contains the event that you want to view.

3. In the details pane, double-click the event that you want to view.

The Event Properties dialog box containing header information and a description of the event is displayed.

To copy the details of the event, click the Copy button, then open a new document in the program in which you want to paste the event (for example, Microsoft Word), and then click Paste on the Edit menu.

To view the description of the previous or next event, click the UP ARROW or DOWN ARROW.

Finally figured out that if I let it sit long enough on startup, it would show that nv4_disp was getting stuck in an infinite loop, which obviously told me video driver problem. I uninstalled the video card drivers, got rid of all traces of them, and reinstalled the latest. Appears to have worked. Thanks all for the help.
