Need help badly computer won't boot after overclock

[PinkF Zeppelin]

i got my e5200 yesterday and i tried to overclock used the asrock oc tool so i didn't have to use bios and i only got it to 3.3ghz so i tried to go into the bios couldn't change my settings manually for some reason i tried using the asrock "easy oc tool" so i used it and set it to 3.5ghz. So i turned it off and now my computer turns on for 5 seconds all the fans go on and the LEDs then it turns itself off and turns itself back on and keeps repeating this forever. There is no video output so i it's not posting i don't believe. So i had a grounding problem when i first built it whenever i would plug in the 12v 8 pin it wouldn't power up but i fixed that but now whenever i don't have the 12v plugged in it doesn't shut down but then i can't use the computer

edit: I have also tried to reset the cmos with the jumper and with taking out the battery i am almost positive i did it correctly
My specs are
Asrock p43de3
E5200 wolfdale
Rosewill green series 530w power supply
160gb 7200 rpm hdd
hp dvd writer
Rosewill aftermarket cooler
gskill ripjaw 4g
Zotac gts 250
Antec three hundred illusion case

Well, it IS a rosewill....

you have got a point

Short of being able to test the PSU in another computer my guess of the two would be the motherboard as I've noted similar symptoms on a failed one but without being able to test the PSU to eliminate it there's no way of telling for certain.

Rosewill have, in the past, been known to 'spec' their PSU's to be able to supply more amps than they really are capable of. In your case it would seem that, for whatever reason, the 12vdc rail is not supplying enough power as evidenced by being able to do a full boot without your HDD plugged in. It would seem (by Rosewill's specs) that this PSU should be able to handle the load. It either does not, or your HDD is pulling a huge amount of amps...

ok well i got it to boot played some games for a while installed a new OS and then i went into the bios and guess what IT HAPPENED AGAIN and no matter how i do the jumpers it won't work again just like before

I have exactly the same problem, using a Pentium G2030 overclocked the CPU by adding 0.250 volts and increasing gaming mode to extreme, exactly the same symptoms, just happened yesterday, what ussually happens is it goes to the "BOSD (blue screen of death)" and tells me that my selected BIOS settings do not meet my hardware and gives me the option to go back to the bios or to reset to default bios settings, however now it continuez to restart over and over again, dont know what to do really dont want to take out all my ram and cpu and gpu, etc. cos my dad is gonna be quite mad if he finds out that i have been messing around with these stuff.

First, this is a five year old thread. Just lucky someone was watching.

Your only answer would be "Reset to default bios settings." You should be able to break into the restart loop, and all SHOULD be OK after. You hope.
