PC not outputting a signal to Monitor

Recently I had a friend of my mum bring me his old pc to update from Windows XP to Windows 7 it worked fine but a few days later that the PC didn't start at all and so he brought it to me to check it out... I noticed that it was coming from the power supply as there was a burnt smell and told the guy to buy a cheap 400W power supply of ebay for €20 as the PC was old and he anyway wanted to upgrade later on... As I got the power supply and installed it, the computer switched on, fans spun and LEDs were on but it was not outputting anything to the monitor. I tried using an old crt Monitor that I had lying around.. still nothing. Not exactly sure as to what is in it but I know it is an AMD cpu, an nvidia geforce card and 2gb of ddr2 RAM. Even though he decided to buy a laptop and told me to keep it for spare parts, I would still like to know what happened. Does anyone have an idea??? Thanks :)

have you tried connecting the monitor directly to your motherboard? maybe the GPU died?

Yes I have still nothing...

welp, worst case scenario the old PSU took the mobo and/or CPU with him when it died. that would definitely suck!

so do you have any other internals you can test it with? i doubt anybody has just piles of old hardare laying around tough :P

To be honest i still have an old gpu lying around but the reason i posted this topic was to see if anyone had an idea so I wouldn't have to troubleshoot to much.. It doesn't matter though because its pretty old so... Thanks anyway
