wish my first post wasn't an issue, but cant work this one out.
My housemate's computer has been doing strange things recently but now seems to have fallen over.
About 2 months ago I helped him upgrade his GPU to a PNY GT 240 (I did mine at the same time so we have identical cards.) Install went fine and everything ran smooth. Then a month ago he started to have an issue. The system would boot up normally until the windows logo, then the screen would go 'no signal'. I managed to get it to boot into safe mode fine and did a restore to before his last windows update and all seemed normal again.
Last night he went to turn on the system and nothing happened. He just gets 'no signal' right from the start. The post noise plays but nothing appears.
First I checked cables were secure, and tried with an alternative monitor & cable, but no luck. So I thought the graphics card might have died, I put it into my computer and the boot on my system went fine. I then put my card back in and then swapped his HDD with mine into my system to see if it was windows. The boot still went fine.
I reassembled his system, but nothing. There is still no display.
