The circuit won’t finish properly on those sections, so it’s best not to touch anything. Just testing a small part might reveal that only a portion of the CPU works, which means the rest needs fixing. Those resistors should be replaced for the system to function correctly.
If unnecessary, they wouldn't exist. Likely they're inexpensive caps for high-frequency power smoothing. You might succeed with a simpler approach or maintain stability at a cost. A skilled person could replace them, assuming they're comparable to others. They're probably described as working but untested—buyers might overlook it if bundled with a motherboard. If labeled untested, it might seem promising but not functional, allowing inflated pricing.
