2 years ago, I built my first PC. It's worked out well with very few issues:

OS: Windows 10 64-bit
Motherboard: ASRock Intel Z97 Extreme3 LGA 1150 ATX
CPU: Intel i7-4790k @ 4.0 GHz LGA 1150
RAM: 24GB (Ballistix Sport DDR3-1600)
HDD: WD Black 6TB Performance 7200RPM
Video Card: MSI GeForce GTX 970 4GB GDDR5
Power Supply: 700W Coolmax CU-700B [Modular]
Monitor: 23" LG W2353V LCD

Recently, I went on vacation and left my PC unplugged the whole time like I usually do. Upon returning, I booted my PC, but the monitor wouldn't display and went into "DVI Power Save Mode". The PC itself seemed to be working normally, just no display on the monitor. I tried turning both the PC and monitor on and off repeatedly. No display. I tried using a different DVI-D port on my video card. Still no display. I switched from DVI-D to an HDMI cable that I use for my TV (as I have no VGA port). Still no display. I unhooked the monitor and connected the PC to my TV via HDMI. Still no display.

I began looking online for an easy fix. I took out the CMOS battery and re-inserted it. Still no display. I cleaned/dusted the entire interior of the PC including the fans. Still no display (and the fans all spin fine). I reseated all the components. Still no display. I checked the voltage on the power supply (110V, as it should be). Still no display. And most recently, I unhooked the heatsink to check the thermal compound, which was (at the time) still moist (but I'll now have to re-apply before trying my PC again). I cannot for the life of me determine what the display problem could be.

Is there anything else I can try that doesn't involve buying expensive parts? I maxed out my credit card on that vacation and really don't have the funds to buy new parts or pay the as-yet-unknown cost of taking it to a PC repair center.

Something else? Very unlikely but not impossible, but I can't think of anything else in your case.

So swapping out your 970 with another card has to be the next obvious step, otherwise you'll get nowhere fast if you ignore the most obvious route to take. Borrow a graphics card from a friend if you can, that'll tell you if yours is kaput without spending any money just yet.
First possibility that comes to mind is that the GTX card has failed, only way to confirm that is to try the card on another system before buying a replacement, or borrow a card from a friend to try on your system in place of your GTX 970.

You could also try re-seating your GTX 970 (remove and re-fit) - - you never know, that might be all it needs.

Thanks, but I already re-seated the GTX 970, and I neither have another video card nor the funds to buy another one. Could it be something else?

I had a hdmi and dp issue on my last gfx card 670(thankfully just upgraded) but it wouldn't work on my pc, gfx card was perfectly fine though or well sorta, it was working but not working, i would have to restart my pc sometimes multiple times for it to work. so i know it sounds stupid, but try plugging it in and restarting your pc a time or two see if it kicks on? might also try to boot it up in safe mode if possible.
