FPS nearly cutt in half on a mapchange.

[equ1n0x]

This is verry odd. I just formatted and installed everything agian, and I noticed that on a map change, my fps would go to my capped 72fps, to about 30fps. It doesnt do it every time, but it happens fairly often. Ive checked configs, scripts, programs, and anything i could think what would be causing this. I have yet to fix it (obviously). This never used to happen before I formatted, and my half life settings are the same as before I formatted... Heres some specs on my comp =\

700 MHz P3
256 MB RAM
Running WindowsXP
GeForce2 MX 200 - PCI :: With the latest detonator drivers.

I run my desktop in 1152x864 resolution at 16 bit colors, and in-game run half life at 800x600. If you need any more information, ill post it after.

Thanks in advance.

does your FPS stay down? do you notice any other activity [such as hard drive access after this drop occurs?]
