PC not booting completely. GPU not detected on monitor after boot attempt.

This past summer I went on vacation and left my computer at home. I turned off the power supply on the back of my PC but I don't think I unplugged it from my power strip. I come back 2 months later and whenever I try to boot it, the fans start running but the occasional beep sound that I get does not play. When I turn the monitor on it displays a gray screen saying "DVI-D No Signal" and then the screen turns off but the PC fans are still running. The only way I know how to temporarily fix it and have it boot completely is to hold down the restart button (next to the power on/off button). I tried turning off the power supply and then turning it back on and trying to boot it, but a message will appear saying that there was a power supply surge and brings me to the BIOs screen. Everything looks fine on the menu. Both fans running and CPU/motherboard temps are fine. What is wrong with my PC? I feel like it's not normal to use the restart button to turn on my computer 9/10 times. Sometimes it will fully boot up but I don't know if I'm doing something wrong or if it's just random. I updated GPU drivers and still no luck.

Is that fairly easy to do? Not really familiar with touching the inside parts of a pc

yikes you might wanna try a different power supply and see if that works

I just checked my PSU. It’s a 600w thermaltake. Should I try a different brand with the same amount of watts?

Is it one of these Thermaltakes...?

Nope this is mine. Meant to say 700 watts not 600 on previous reply.
