We have sql server 2005 enterprise running on a power edge 6850, raid 5, 8 cpu, 4 gb ram. C drive 12 gb with 4 gb free space.  we have a .net ERP  application using this db, with about 50 users.
Problem is users experience sporadic system slow downs (only the ERP app). It happens intermittenly. Some user will
experience the slow down for say half hour (reading and writing to the application is very slow), while
at the same time other users are fine. Then the slow down went away, and may come some time later to  other users.
I saw spikes of physicaldisk read/sec and average que, sometimes in page/sec in the db server performance monitor. But I don't know these spikes can be interpreted as problem or not. Can someone look at the snapshots and tell me? Any suggestion is greatly appreciated!
(I am attaching the screen shots of the performance monitor for both a 1 minute snap shot and a 43 minute snap shot, as well as the txt 43min log file recorded every 15 seconds)
