I am getting stop: c0000135 unable to locate component, this application has failed to start because MSVCR80.dll was not found.. how do I fix when i cant get past the blue screen?

Not sure what os you're running, and assuming it's xp, but see helpful links below.
To get past the blue screen, you need to press f8 during boot up, try using last known good configuration to start windows. Otherwise, try booting into safe mode. See the Reboot instead of shutdown section in this article. to disable the restart on system failure. Also helpful may be this link or this link or this link. Here's one more I saved. Unfortunately, many of the MS links are no longer valid, now that support for xp is dropped.
If you can run chkdsk on the system, you might be able to recover corrupted or bad sectors that caused the dll to be lost. For a list of device error codes, see here.
Also consider the possibility that malware is responsible. In that case, use MBAM to scan the system.

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.
