No Display on monitor after restarting from BSOD

Hi,
I got some problems on my computer parts today.

I ran Prime95 for LESS THAN A MINUTE (I stopped it after the cpu temp reaches 73C, it increases really fast). Then I turned off my desktop to cool down the cpu. I turned it on after about 45 min. Everything works normally. About 10 minutes after booting, BSOD comes up. (At that time I was playing a game on my phone.) Therefore, I pressed the restart button. The hard drive and all fans were still working but my monitor says "NO SIGNAL". So i tried unplugging the VGA cable and plug it in again, still nothing.
Then i tried to remove a stick of ram (my mobo have 2 slots) and then POST came out and says "Overclocking or overvoltage failed". So i open the bios and underclock my processor. Everything becomes normal. But when i plug in the ram, the problem came up again So i was wondering which part of the computer is broken/dead/loose/malfunctioning etc. and what should i do??

Specs:
Mobo: ASUS P5KPL-AM SE
CPU: Intel Pentium Dual Core E5200 @2.50 GHz (Overclocked to 3.00 GHz)
RAM: V-Gen DDR2 800MHz 2+1GB
GPU: Intel G33/G31 Express Chipset (Integrated)
PSU: 450 W

Any help is appreciated.
Thanks.

At a rough guess, Id'say the RAM was hosed.

Thanks for answering.
I tried unplugging one of the ram and still doesn't work. I think both didn't work, or the slot was broken.
Should i bring my rig to a professional and let them fix the problem?
