What he said.. Might be better overall to move both rails and drill new holes about 1" - 1.5" above or below (for both rails) so that way the rails and tray are squared & level for proper function. "Liquid Nail" or caulking may work well (thin application between length of rail & wood) too, but you'll still need your screws. When that dries it'll reduce tension on the screws by having more contact spread down the rail instead of just the screws = stronger support
I ended up just filling the wooden hole with super glue, then pressing the screw through the other side, and it spread like thermal paste lol. then i just sat by the computer desk and kept pressing the screw in with my finger nail for about 10 mins or so, then left it to try for a couple hours - and it seems to have done it! keyboard tray feels nice and stable now now to clean all the wood dust lol...yeah sucks that its made out of particle board, but as far as computer desks go, i love it! has a nice cubby on the right side at the bottom and on the top right side has a little elevated area you place your rig and there's an elevated area on top of that where i put my right speaker and my gaming headset xD
