Your problem is that there are too many drawers in one window. Each drawer has a .info file associated with it which contains a graphic of the icon for the drawer. If you have hundreds in one window your machine will run out of chip RAM, despite all the icons being the same. Personally I'd delete all the drawer .info files as they're pointless and only slow down directory reads of your games. Use a file manager to navigate through your games such as DOPUS, then set a custom button up in your file manager called WHDLoad and have it launch your slaves at the touch of a button.
On such a low spec Amiga as yours, use AGLaunch or TinyLauncher or XBench right from bootup instead of loading Workbench. You can run WHDLoad this way with 2MB chip RAM but it's hardly fun and a lot of slaves require a 68020 CPU and more RAM.
Your best choice here is to buy an ACA 620 card. That will run all the non-AGA games as it has a 68020 CPU with plenty of FastRAM.
Another choice is a 2MB or preferably 4MB PCMCIA card. But again, due to lack of 68020 there's a good chunk of slaves that will not work unless the slave authors fix them for 68000's. When I last fiddled with a 68000 WHDLoad machine which was 5 years ago I'd say a quarter of games wanted a 68020...this might be better now, I'm not sure.
