which debug tools do you use?

[kcynice]

I know softICE is a perfect debug tool but when i installed it on my computer,it would lead my system to die. I use windows xp sp2.
so,i have to use ollydbg.but there are some limits.

[coz]

Because Softice doesn't really work on XP I've always used Ollydbg and sometimes PE Editor and IDA.
