WOTLK Screen going nuts like my video card is crashing...

Server: Icecrown
So the last 2 weeks I've been getting a bit of a messed up screen. Its breaking into triangles like my video card is crashing but only while playing Warcraft. I've been able to run BG's and raids on maxed settings with no issues. Sometime last week I started to get a bit of "Screen breaking" after 2 hours of play, and it's slowly been getting worse. I can play COD6, Fortnite, Apex World of Tanks ect ect with no issues for hours on end but i find it weird how now WOTLK is starting to crash. Has anyone ever had this issue or know of a resolution? I have not changed my settings, mods or downloaded anything for the game in a long time. Any help would be appreciated. Thanks

Hey Shred92, TY for the reply and advice. I was giving it a few trial days before replying and here's where i'm at.
So, I went through the steps and It worked well for a day with 2 crashed from "Not enough memory". Then day 2 the crashing really started. I logged about 4 hours of farming mats and the game crashed every 20 min or so. Last night I ended up getting kicked out of my ICC 25Heroic because i was crashing mid boss fight every fight. I'm downloading a new version of WOTLK off warmane's torrent now and ill try just starting over to see if that helps. Fingers crossed...

What's the crash message?

If you have a modified version of the client, that's the first thing to get rid of.

Another Update: New client and new addons and not 1 crash with about 15 hours of play. Farming and 2 raids (25TOGC and 1/2 a 25M Ulduar), no diamonding / video scaling issues (Or whatever its called).
The error was claiming to be a memory issue. I don't have permission to post images, so here's a link the the actual crash pictures.
Errors: "Requested 47147280 bits of memory" / "The memory could not be "read""

Nothing's modified. I downloaded wow client off Warmane's download torrent about 7 years ago when i found Warmane, Downloaded a few 3.3.5a addons for AH, Professions and raiding and have been using it for the last 7 years with no issue. Addons were all from reputable sites like curseforge, Legacy wow and warmanes's forum. The saddest part is 7 years of data from scanning the AH once a week is gone. All my settings for addons, all gone. I'll never get my healbot settings the way I had it set up for all my healers and alts. /cry
I tried moving the old addons and WTF folders over to the new client, but no AH data and other addon settings are saved.

You haven't copied your settings properly, because they should work.
