system lag and hesitation,

Posted on 2008-06-12
Last Modified: 2013-11-08
I have XPPRO SP2, Office 2003, Gigabyte P35-DS3L MB (bios2.4), EVGA NVIDA 8800GTS 320MB DDR3 Dual DVI, updated driver. 2GB RAM, 500GB SATA HDD, LITE-ON DVDRW LH.

I have this system hooked up in a sound room. One DVI is hooked to my monitor the other is hooked up through a 75 foot cable to the projector (the cable is VGA) to a SHARP XG-C430X, I am using a Kramer for the Switcher/ Scaler. This allows me to hook up DVD/VCR/Components etc to a sound board and run through my PC.

The problem I am having is when I have both of the Video ports hooked I have some lag time when I point to START. Sometimes it is just grey for several seconds. When I point to a file to open it has some hesitation 5-10 seconds. I have run the dual monitor configuration several times trying different Resolutions, swaped out primary and secondary monitor, changed hertz, I have adjusted the Video Memory and Core bus thinking this might help. No help. I have gone through most of the basic checks. But still get this lag and hesitation. Some of the presentations I do are live and it is a real problem with this lag time. I am thinking that it is either Software related XP OS, or The video card plus long VGA cable to the Sharp projector.
If you can help thanks!

Ok whilst the length of the cable is not helping it shouldnt affect teh eprformance of the machine you should just see signal degredation and picture quality drop off on the external screen, however the booster shoudl compensate some for that.

have you checked task manager at teh times of the delay to see if there is anything tyhat is proving to be running taking up your cpu at the time of running, when did you last defrag

whats your paging file setup

i think this is more OS/machine based

It's a brand new system, less than 1% of fragmentation. There is no constant time that it does this. And the picture quality is great on a 8'x8' screen.

I have considered that it might be the OS, but can't find anything that would make me to want to reload the system.

run process explorer and keep an eye on drain during times of lag and try an didentify what is causing the lag as must be a process

Thanks for the reply, out for a few day. I checked system processes and CPU History no change.
Any other ideas no matter what I would appreciate it.

wasnt looking for a change i was trying to identify any processes which are causing the lag so when it happens identify what is spiking the machine

the only thing i would also be checing is your ram setup, you are running two videocards at the same time probably uf they are to a screen high def ones which are notoriously memory hungry it could be spiking the processor and ram, consider going up in RAM, you havent let me know how much you have and also change your virtual memory setting to be system managed to see if that helps

Thanks, but I gave the extra info so you might know I checked both spikes and what processes are running. I am using 2gig of ram. I have one dual (DVI) EVGA 8800GTS NVIDA with 320mb of DDR3. One of the first things I did was to adjust the paging file for virtual memory.

Thanks for the help, I am sure that there is something I have missed.

is it one stick of 2gb ram of 2x 1gb. 2 x sticks will run better than 1. def leaning towards system perfomrance here but going to be hard to track it and optimise from here.

if you disable one of the VGs im guesiing you dont see this?

thanks for the imput, I will check the memory again I could have missed it. I have two sticks of 1Gb memory. I am going to swap out the video card just to be sure and check it then. From their I will try the extra memory. Besides reloading or swapping out the other hardware I don't know that I have other options. Thanks for helping to eliminate the other possibilities.

Thanks for the help. I know this was different because of the media and sound addition. But I agree that it might be something related to system performance. I was trying to avoid reloading the OS and/or swapping out hardware since I use this PC so often in the sound room. Everything gets put on hold (lots of STRESSSS from everyone when its down). Thanks again!
