Lags when entering Warcraft 3 TFT (Warcraft 3)

Guys I have such a problem, I started to lag Warcraft 3 TFT 1.26a. It all started with the fact that I tried to host the game in rubattle.net using a bot, well, something happened, something didn’t, I decided to uninstall this program, I deleted it, and after that I could not connect to the network, well, I think it will pass, and went into a single-player game, Launched a photoman frenzi map to see what kind of map it was, and then such hard lags just started that I decided that something was wrong with the PC. I go to the desktop, everything is fine. I go to the game wild lags. As a result, I crap and rebooted the PC, sighing with relief before entering the game, I prayed, but in the end it did not lead to anything. All the same fucking lags are all the same, I think we can check the virus for viruses, reinstalled the game a couple of times, at some moments it worked, but I need patch 1.26a when it changed, everything was the same .. I don't know what's the matter, but I've already tried everything except reinstalling Windows. Do you really have to reinstall ... Help with advice, maybe someone came across this. (PS before it all started, I installed Warcraft 3 TFT on a flash drive to play on a laptop, when the PC is busy with a girl, in the end I tried to go to the PC from the flash drive to play, nothing happened all the same lags. But on the laptop it is normal. But it is weak and warming up -_- impossible to play for a long time)
