I cant play Garrys mod. PLEASE HELP :D!

I cant play Garrys mod. PLEASE HELP :D!
So, i installed about 500 mods today. after a long time of the installing I tried to play. I tried to use two maps that were new first and after both caused me to crash, I used the original default sandbox maps. I crashed again. I have plenty of memory on my pc and ram wont be running low. I think one of the mods may be causing the problem but with roughly 120 pages of mods it could be hard to find the one.
Please tell me segestions thanks!

Uh, delete some addons?

Your anwser is pretty obvious, Delete addons…
