no video on reboot

my setup works fine at normal speeds. i try to overclock to 3.6ghz without any voltage increase and the computer runs fine but when i reboot my video goes out and wont come back on. all i need to do is power off completely and it works fine.

do i need to increase the pci-e voltage or something? how do i know how much without damaging my card?

any ideas would be nice, thanks

You cannot change the voltage of the pci-e without a voltage mod. What psu are you using?

its and @power 500watt

its got it in the bios maybe i am mistaken

 

[waylander]

usually the only voltages you can change are the cpu, chipset and ram... and I've never heard of @power before... generic psu's should not be used to OC. You should check what the actual voltages are using a multimeter, they should be +/- 5%, you can check this in bios as well but won't be as accurate.

alls good. i fucked up somewhere along the way but it works fine now.
