New computer can't start after bsod

I think this may be a hardware issue. I assembled this computer 2 days ago. It worked fine for a few hours and i got my first BSOD. restarted no problems. However today i used it for about 3 hours, no problems. While i wasn't using it, it suddenly BSOD and said theres an error. Since then after each restart, right after i type my password and the desktop is loading, it Blue screens and restarts. I could get into the safe mode about 30% of the time w/o it blue screening after typing password. I took out my 4 sticks of ram, tried each one at a time, didn't change anything. I did a system restore to earlier today and it is better. I can at least get passed the desktop loading part sometimes. However i'm still getting blue screens when im using the computer fairly commonly.

however then later on, i couldn't get into windows, i only see the motherboard thing and i couldn't get to bios because any button i press would restart the computer. couldn't load boot CD either. however, now when i turn it on, the monitor says No signal. Tried it on TV, no signal either...

i have no idea what problem it is. at first i thought it may be driver issue. now i dont know and think its hardware? any ideas is appreciated!!!

Oh I was on windows 7 64 bit.
I have antec earthwatts 650W

That's rough man! Do you have access to another video card or PSU to try? I'd start there as you have already done and eliminated the normal work so far.

 

not really. i have a 6 year old computer that i was using before i built this. i dont think the psu can handle the gtx460... and i dont have another video card =(

 

Whoops man, that changes the game! I've got a GTX460 running fine on a 500W PSU. Your power supply is probably toast. Get a decent PSU. What, $40 bucks or so?

 

Hi, auggie.

He has a good PSU in this computer but it can't run the card in his old one to test.
