no signal to monitor, no keyboard, no boot

[rayancaleb]

Hi,

HP Pavilion p6-2364ea Desktop PC

Have had this Pc for 2 years, installed a graphics card 12 months ago, all good.

Recently wanted to upgrade the card, so bought a NVIDIA GTX 750Ti 1020MHz (Boost 1085MHz) 5400MHz 2GB 128-bit GDDR5 HDMI DVI-I DP PCI-E Graphics Card

as this was a low power card had read this would be ok. ( maybe bad advice that! )

After install of the new card got no signal on monitor, no reaction from keyboard or mouse. Pc appeared to be powering up in a loop.

removed card, and went back to the old graphics card, - same result, no signal etc

removed old card, and went to use onboard connection, - same result, no signal etc

Any idea?

Please help.

Thanks!

I didn't find the right solution from the Internet.
