Church Computer problems

My church's computer seems to have a virus, anytime I boot the computer and it goes into standby mode, the screen is totally blank. When i do take the resort to clean the virus it sends me to microsoft live safety website to clean up the virus. I recently purchased the McAfee virus scan program but i can't get it to run properly so it can clean the virus. What do I do? THe operating system is XP

Have you tried running an online virus scan like housecall?

The screen is supposed to blank in standby mode.

Is there any anti-virus software already installed? One resident AV is all that should be installed.

Another free online scanner which is very easy to use is Bitdefender:

What exactly are the symptoms that make you suspect a virus infection?
As willcomp says above, the screen is supposed to go blank during standby...

free scanners are good, if you can boot up.
In this case, take the disk out, and hook it to a working pc as slave, or as only drive onthe second ide cable (remove all other devices). then do those scans ; updated :

When the screen goes blank, the computer activity does not resume. Therefore, i have to shut it off by pressing the main power button.

if i press the enter key on the keyboard to bring it out of standby mode it doesn't resume activity.

Try the spacebar or moving the mouse. Could be a problem with resuming from standby -- not uncommon.

What about other AV installed?

sorry about being late to reply. Now at times the computer freezes and it doesn't respond to any tasks.  I shut the computer down by pressing the power button for 10 seconds. What does mean? What do I do when this happens?

willcompCommented:
Assume the computer "freezes" with display still shown and that keyboard and mouse are unresponsive. Such symptoms are often caused by an overheating video adapter. Have you checked the interior of PC for functioning fans and dust buildup?
0
 
nobusCommented:
could be any hardware causing it. you can diagnose by disconnecting devices.

cnandrewsAuthor Commented:
okay i will check the interior for dust buildup.  Mr. nobus come to think of it there have been some issues with the printer not printing documents.  A error message will come up when the printer pops up in the task bar. in the printer queue it says "error-document name".

nobusCommented:
you can also start with the minimum, and test :
mobo + cpu + 1stock of ram, ps, video card, 1 HDD, keyb + mouse

cnandrewsAuthor Commented:
how can i test to see if it is operating properly.
0
 
willcompCommented:
What I'd recommend is to remove all PCI cards, disconnect floppy and hard disks (both power and signal cables), and disconnect all external devices except keyboard (includes printers and USB devices).

Then boot from the UBCD and test memory using Memtest 86+ for at least 4 passes. If memory is OK, reconnect hard disk and test it using manufacturer's test. If PC locks up during testing, it's probably video adapter (which I surmised initially). Only way to "test" video adapter is to replace it or, in case of on-board adapter, add a video adapter.

Another good test is to boot from a Knoppix CD and see if problem occurs. If it does, then it's a hardware problem and not a Windows problem.

Would you mind explaining the C grade. Several people tried hard to resolve your problem.

willcompCommented:
I'm not referring to the split, that's fine. It's the C grade. If you are new here, please read this:
