Computer Problem

[CTU_Clay]

Computer ProblemI have a problem that just started regarding Silent Hunter 3 & 4 and frame rates:

While running SH3 or SH4 in single play or MP mode; frame rates start out in the 50's and drop to 2 then back up to 30's then back to 2; creating alot of lag or even stoppage of video. not freeze. Just tremendous lagging.

I have cleaned the video card fan and cooling fins.
Cleaned the processor fan and cooling fins.
Cleaned the power supply fans.

My video card is a BFG Nvidia Based GeForce 6800 GSOC AGP 256 MB
My Processor is a AMD Barton 3000
Power Supply is a ANTEC 550 watt
Video drivers updated/tryied.
Memory (3 Gig) Checked for tightness in board slots.
Fan Speeds monitored and no big changes in speeds.
Temps being monitored for motherboard and CPU. No problems in that area noted.
Anisotrpic filtering is in "application controlled" mode.
Vsync is enabled.
Windows SP3 totally removed.
SH3 & SH4 uninstalled and reloaded.
Search & Destroy ran and all spybots removed.
Virus scan done. No virus' found.
End-It-All ran and made no differences. Still Bad lagging to 2 FPS.


This just started doing this yesterday after no problems for a couple years.
SH3 & SH4 are stock, no mods and patched to 1.4 only.

Any one have any suggestions.
