Bought a pc about a month ago and it was working fine until it randomly crashed while browsing internet and now it will not boot up.

If I try turning it on everything seems to be fine except it wont display and after a few seconds the GPU fans stop working and the case, CPU and PSU fans start blowing very loud.

PC specs:
GPU - RX 470 8gb
CPU - I7 860
16GB ram
Some old HP psu which I could not find the model for (320W)
Motherboard is intel Q57 express.


Any idea of what the problem might be?

This GPU requires the system to be powered by a PSU with a minimum of 450W, 30 amps on the +12V rail and depending on which version of the card you have it needs either a 6 or 8 pin PCI-E supplemental power dongle from the PSU, HP use cheap generic PSUs as their computers are primarily only intended for office/school type computers that don`t have a power hungry add on video card, an under powered PSU can work for a while but what happens over time is that components get damaged by power starvation and being the most power hungry the GPU has problems first.

Best suggestion is to ask around to see if there is anyone that can test your GPU in their computer, it must have the power specifications that are detailed above.
