Tekkit isn't working anymore

[thehighace]

So i started playing tekkit with the technic launcher a few days ago . All good . I added 3 extra mods and still worked . Yesterday when I booted up my PC and java started using all my PC memory and CPU . It gets from 200k(wich my vanilla MC works) and then rises to 900 k and 99%CPU , and it won't work anymore , it's like server lag , when i brake something i won't get it , i can't open chests or anything else . The mods that I added are dartcraft veinminer and openblocks , but they worked fine 2 days ago . Please help I really want to play again .

 

Things I tried :

-Making another save , i tought that the save was corrupted

-Making a batch to run tekkit launcher with java -Xmx512m -Xms256m -jar Tekkit.exe(found that on some forum)

-Reinstalling java

-Reinstalling the modpack

-Giving javaw.exe realtime priority

-Rebooting PC

 

None of them worked .

After getting at 900k it stops working , so i can play like 30 seconds and then i need to kill the process and restart MC .

 

And sorry for my english , not my native language .

 

Edit :

My PC specs are:

-AMD Athlon x64 2600 dual

-4 gigs of ram

-Nvidia GeForce GT 430 video card

-Windows XP x32

-Java 7 update 51
