Hellooooooo all!
not sure where 2 post this question.
ok i am havin major problems wen playin any of my games.
every time i try 2 play Mohaa, SH or any others, it crashes.
usually wiv in the first 5-10mins. then the only way 2 turn off my computer is manually! it just freezes and repeats the same sound over and over again. Then wen i try 2 play the game again, after restarting the computer, it tells me 2 play in 'Safe Mode' which i h8 b cause i hav 2 change all the settings!
ive tried everything i can think wiv no luck (re-installed it 5 times, gone in2 the Registry 2 delete folders, deleted all Mods i hav, virus scanned, etc etc).
if any1 has any ideas, i mean ANY ideas at all!!! can u plz tell me!
thx in advance
