I just replaced my 400W PSU and got myself a 520w. However, my computer doesn't boot up. I thought maybe it was a problem with the new PSU but the same thing happens with the old one. My motherboard led turns on, processor fan starts running, graphics card fan also runs but I don't see anything on the monitor. Just a blank screen with the monitor light blinking. What do I do?
I had a BSOD the previous day but when I restarted it worked fine and then I replaced the PSU.
Did you connect the CPU power connector?
I made this silly mistake when I was assembling the rig shown in my sig.
