Hello all.

This week my computer kept randomly freezing at different time and the only way to use it again was to switch it off and reboot it. During the reboot I had a message saying it was scanning disk for consistency. Then delete corrurpt attributes, something about orphaned files(?) and other things, and then finallly coming to my usual enter password to access windows.

This happpens repeatedly, and now when it starts up i get a message about riched20.dll couldnt open

Have I got a trojan/virus? Im really new to all this and Im worried my computer of 4 months has broken already!

Any advice is gratefully recieved and apologies if Im posting in wrong forum

Are you using Outlook for email? If so, this article may help with the error message: http://support.microsoft.com/kb/291651

Anytime your PC is not properly shut down, Windows will run a disk check. This will scan your hard drive for errors that may have happened during a disruptive shut down. Riched20.dll is a file which contains functions for rich text edit control. Typically, this file is often used in Office, Outlook, and other word processing programs for text. Damage to this file may prevent it from opening. What errors are you getting when your PC freezes? Does it just freeze with no message at all?

no messages at all. It is usually on the internet when it happens..

It doesnt matter what keys i press nothing happens.

ctrl alt delete therefore doesnt work

i just have that blue 'thinking' cursor ring on infront of whatever page i was on

the other occasions when my pc hasnt shut down properly, on reboot i have the open windows in safe mode, and the other 2 options. It never before automatically went to the scan disk

When a PC freezes like that, it is generally an indication that something is seriously wrong. Whether or not Windows runs a disk check sometimes depends on how the PC froze. A PC I had a couple of years ago would freeze when placed under certain kinds of CPU stress. It would rarely scan the disk, more often, I would return to Windows as though nothing bad happened. Your issue could be hardware related. Have you done anything to the PC such as install new hardware or drivers?

Try a hard drive diagnostic. You can find links to the more common manufacturers here: http://www.bleepingcomputer.com/forums/topic28744.html

Select the Hitachi Drive Fitness Test and run it. It'll list a model number for your drive - and that can be googled to find the manufacturer. Go ahead and run the Hitachi test anyway - if it fails your drive that's a good indication that it's dead/dying

C:\\Windows\system\RICHED20.dll is either not designed to run on
Windows or it contains an error. Try installing the program again using
the original installation media or contact your system administrator or
the software vendor for support

Try running chkdsk /r again - if it gives errors again I'd suspect your hard drive.
If not, then it's likely a software issue - which could be malware or an OS corruption.

Here's some free, online scanners to help rule out malware: http://www.bleepingcomputer.com/blogs/usas...?showentry=1252

You could try replacing the Riched20.dll file. Updates and other program modifications may have corrupted that file. You could try downloading a new Riched20.dll file. But, that won't stop your PC from freezing.

This link may help: KB236053. Have you run a virus scan on your PC?
