I'm trying to decide whether to revive my old gaming PC or replace it entirely. It has an Intel i9-9900KS, a GTX 1660 Super, and 16 GB of DDR4 RAM, although one stick was damaged during installation and I'm currently only using 8 GB. The computer has never been properly cleaned or had its thermal paste replaced, and it has been sitting unused for nearly a year while collecting a lot of dust. I'm also unsure of the power supply, but the system turns on and off repeatedly and no longer displays an image. I'm not sure whether the issue is the PSU, motherboard, RAM, graphics card, or something else. I mostly play single-player games such as Cyberpunk 2077 and Red Dead Redemption 2. Would it be worth cleaning and troubleshooting this system, upgrading it gradually, or would building a completely new PC be the better investment?

It’s definitely worth troubleshooting before replacing everything. Disconnect power, remove the damaged RAM stick and graphics card, carefully clean out the dust with compressed air, and try booting with one known-good RAM module using the processor’s integrated graphics. If it still powers on and off, the power supply would be one of the first parts I’d test or replace. Don’t keep repeatedly powering it on if the PSU is failing, since a bad unit can damage other components.
That CPU and graphics card are old, but they’re not automatically useless. A 9900KS can still handle everyday tasks and plenty of games, and the GTX 1660 Super is usable at 1080p with sensible settings. Clean the machine first, confirm the PSU is safe, and replace the RAM if necessary. Thermal paste does not need to be changed on a fixed schedule; if temperatures are normal, it may still be fine after several years.
Older systems can still be perfectly good for browsing, programming, lighter games, and general use. A new build only becomes more compelling if you need much better performance in demanding modern games or want to do things like serious 3D work.
Before spending money, figure out what is actually broken. Remove the GPU, test with a single working RAM stick, reseat the power cables, and check whether the motherboard gives any diagnostic lights or beep codes. If the PC works after cleaning, you may only need a reliable PSU and replacement memory. If several major parts have failed, then putting the money toward a new build makes more sense.
My main goal is playing newer story-focused games, so I’m trying to work out whether repairing this machine would be enough or whether I should start over.
I damaged the RAM by using too much force when installing it. The stick is slightly curved around the edges, but it isn’t obviously snapped.
