Apps force closing and htc pico switching off every time instantly after turning on

Please help.......:(
i rooted my htc explorer, installed custom rom and increased memory by using mounts2sd and terminal emultor using this method:-
m2sd data disable
m2sd apps disable
m2sd cache disable
m2sd dalvik disable
m2sd dlcache disable
m2sd readahead 512
m2sd rmount enable

which worked like a miracle....... But then i tried to increase ram by using ROEHSOFT RAM EXPANDER (SWAP) which constantly rebooted my phone.........
Every time i deleted any app, removed from charging it kept on rebooting and i had to restore backups.
then i tried to start evrything from beginning and wiped everything.. including the ext2 partition.
and then i installed the rom it turned on but flased that :-
Media storage has force closed, contacts has force closed and etc and then it is switched off automatically.
PLZZZZZZ HLP ME WHAT SHOULD I DO.....
