Check to see if the fan of PSU is spinning or not ! If not, RMA the PSU ASAP, its faulty. And VS 550 is not a trusted unit and not even 80+ certified.so you are telling me that even if i get the psu replaced it will have the same problems? the vs 550 did get good reviews so i went for it.

how will clearing the cmos help?1. The new PSU is defective;
2. The new PSU is not compatible with your motherboard (not very likely).

does the bios modify every time a psu is changed? i don't think there is a POST problem as i am using the same pc with the stock psu right now.i may be wrong.i don't know

With that GPU, the old PSU should be fine. Read this review http://www.legitreviews.com/gigabyte-radeon-hd-7770-oc-... where the whole system draws less than 250W at the outlet with an HD 7770. Your system may draw more power, but you haven't provided any info. The PSU recommendation is just in case a buyer has a really crappy PSU that delivers much less power than its rating. What are the specs of the PSU in your HP system?

As long as your old psu has one 6 pin cable for the new video card, you're fine with the old psu. If you new PSU starts, doesn't mean it's working properly. I had a defective psu that it was booting fine until the video card (which was entry level) was starting to be use by windows and then the system was freezing. Without the video card, the psu was fine, booting properly in windows with the onboard video card. So the paperclip test it only does half of the job.

ok now, I understand! It needs to completely boot and work fine when connected to the mobo and the others..
ill just return the PSU and forget about it..
