Hello,

A couple of days ago I decided to put a password on my user account. I am the only user on the computer, and I have administrator status. When I added the password and rebooted, the welcome screen stayed longer than usual, and then I was shown my desktop picture but no start menu bar, no icons, nothing. I was able to access Task Manager, and went poking around in dos.

We saw that "explorer.exe" was missing, so I tried FixO (suggested by another thread on this site). Two of the files in that zip appeared, but the third (restore.reg) was hidden, and I couldn't figure out how to unhide it. Eventually, I booted from the Windows XP disc, and that made my start menu bar and icons come back. I tried to do a Windows Update, but was prompted to update my windows update software. When I tried to do that, I got various error messages (a couple of different numbers). I updated Avast and ran a thorough scan. It found 5 trojans in 5 different places. I moved them all to chest and then deleted them. I ran another scan, and it found nothing.

I noticed that I was getting no sound from my speakers (back when I had no start menu bar or icons, I still got the Windows Welcome Music everytime I rebooted, but now that was gone). I was just getting the occasional beep from the CPU. So I went into Control Panel. The audio settings buttons and menus were all greyed out. I reinstalled the monitor driver (speakers are on the monitor). No change. I googled that problem and saw that maybe my account didn't have permission to change those settings. Checked my user account, checked regedit, and I'm still an administrator and all the right administrator permissions were checked.

Today when I got home from work, I turned on the computer to find that the internet didn't work. No available wireless connections, a network cable has been disconnected, etc. Same as with speakers -- when I brought up the settings windows, everything was greyed out, and there were no available wireless networks. I tried to print off some work I had to do at home, in case something else decided to go, but the printer wouldn't print. No error messages, though; it just didn't respond. The printer icon stayed in the system tray (it's still there, 3 hours later).

I have no idea what could be going on. I hope someone can help me!

Many thanks,
Mel

Are you sure that you are 100% clean of all malware?
If not, then go to the Malware Forum

http://www.geekstogo...uide-t2852.html
Follow that guide, and post the required logs. Once the techs have given you a clean bill of health, then we can proceed.

In this thread, give me the make and model of your computer.
Also give me an Everest Report (Click on "Everest Instructions" in my sig and follow the instructions)

All right then! Going on the chance that this is not a malware problem, we will try some things here.

Use the hotkey WIN (the key with the windows logo on it) and Pause/Break
Then go to the "Hardware" tab and select Device Manager.

Expand Network Adapters, and tell me what is listed under there. Also tell me if any devices have a yellow mark next to them.
Do this for the following categories: Sound Video and Game Controllers
Modems

Tell me the make and model of your computer. Also tell the make and model of your printer.

Here we go:

Network Adapters (no yellow marks by either):
- Atheros AR8121/AR8113/AR8114 PCI-E Ethernet Controller
- D-Link WDA-2320 Desktop Adapter

Sound, Video, and Game Controllers:
- Audio Codecs
- Legacy Audio Drivers
- Legacy video Capture Devices
- Logitech Mic (Communicate STX)
- Media Control Devices
- Realtek High Definition Audio [[this one has a yellow and black exclamation point over the icon]]
- Video Codecs

There is no "Modems" listing.

I'm not sure if the computer actually has a make and model... we built it from various parts bought online (some of them are listed at the top of my last post). In the "System Properties" window, under the "General" tab, under "Computer" it says:

Intel® Core™ 2 Quad CPU
Q 8200 @ 2.33 GHz
2.33 GHz
3.25 GB of RAM

My printer is an HP Deskjet 5940

Also of note: when I got home from work today, the internet said it was connected to a wireless network, but it wasn't connected to MY wireless network, and I still couldn't change any of the settings or view available wireless networks.

Ok. Lets try to get that printer working.
Go here: http://h20000.www2.h...SeriesId=445462

Choose your operating system and language, and download the driver. Then install. After installation, reboot. Can you print now?

Is your mobo a:
ECS P43T-A2?

If so, go here: http://www.realtek.c...p;GetDown=false
Download and install the driver for Windows XP.

Tell me all the components used in your computer (if there are too many, only list the important core components)

By the way, you seem to have built a very good computer.

That is indeed my motherboard.

While I'm doing that, here are the components (and thanks! we love it except when it doesn't work!):

- Samsung Spinpoint T Series HD501LJ 500GB SATA2 7200RPM 8.9MS 16MB 3.5IN Hard Drive OEM 3YR MFR Wrnty
- ECS P43T-A2 ATX LGA775 P43 DDR2 1PCI-E16 2PCI SATA2 HD Sound GBLAN Motherboard
- Crucial Rendition 2GB 1X2GB PC2-5300 DDR2-667 240PIN DIMM Memory
- Intel Core 2 Quad Q8200 Quad Core Processor LGA775 2.33GHZ Yorkfield 1333FSB 4MB Retail Box
- Microsoft Comfort Curve 2000 Keyboard English USB WIN/MAC Black
- LG GH22NS30 Black DVD+RW 22X8X16 DVD-RW 22X6X16 DL 16X/12X 2MB SATA OEM
- Powercolor Radeon X1550 256MB DDR2 PCI-E VGA DVI-I TV Out Video Card
- Apex PC-375 Mid Tower ATX Case Black 4X5.25 1X3.5 4X3.5INT 400W

Oh, the monitor is an AG Neovo H-W22 DVI.

Okay, the printer driver install failed. When I went into control panel and clicked on Printers, it had two of my printer. One was called "HP 4900-Series," and it had a checkmark but said "offline" when I hovered over it. The other one says "HP 4900-Series (copy)" and it says "Ready" when I hover over it. Is that normal?

It's great to know that the printer is working again! :)

Now, go here: http://www.ecs.com.t.../...=44&LanID=0
Download all three drivers and install.
These are for the chipset (not your problem, but an update is always good)
LAN (for your internet prob)
Sound (for your sound prob)

I downloaded the 3 drivers and followed the instructions rshaffer recommended:

1. Installed chipset driver and rebooted
2. everything same as before
3. Installed LAN driver and rebooted
4. Same as before (wireless card can connect, but only to "default," an unsecured network in our building. I can't "view available wireless networks" and all options are greyed out. Ethernet says "a cable has been disconnected")
5. Followed steps to install HD audio on page suggested and rebooted
6. everything same as before (no sound), and then a few minutes later, got BSOD with following line:

STOP 0x0000007E (0xC0000005, 0x80535485, 0xF78F290, 0xF78F2680)

7. Shut down computer and restarted.
8. Sound (huzzah!) and everything else working normally
9. After a few minutes (longer this time), got same BSOD again.
10. Shut down computer and haven't restarted since.
