I was trying to revive an older PC by replacing CPU heatsink and GPU heatsink, adding a new PSU and a few more RAM.
After I put everything together, the PC would turn on, with fans, HDDs, everything sounding like it should, and remains on. However, it will stop at POST. Sometimes even just freezes at the motherboard brand screen and hitting DEL for BIOS or Tab to view POST will not respond. After that whenever I restart the monitor WILL NOT TURN ON.
The weird thing is, if I leave it completely unplugged for a few moments/hours and power on again, I will see the partial/unsuccessful boot end with a freeze. And again, in subsequent reboots the monitor remains off.
I was wondering if anyone has experienced similar issue after putting a PC together?
Tried just booting with one RAM, clearing CMOS, with a PS/2 keyboard, without HDD... still can't seem to pinpoint the issue...
Could this be heat related?
CPU has no bent pins.
One thing I should point out is for the video card, the VRM sink fell off. But I've read cases where those sinks aren't entirely necessary and the card will work without those sinks.
