One of the most important parameters in evaluating a high frequency chip capacitor is the Q factor, or the related Equivalent Series Resistance (ESR). In theory, a "perfect" capacitor would exhibit an ESR of 0 (zero) ohms and would be purely reactive with no real (resistive) component.
Try Aida64 to scan and list all hardware in your PC. You can get a free 30 day trial. If that fails you can try some kind of linux liveCD/liveUSB and try your luck there, often it will show more info than windows does.. If you fail to get the proper hardware model number it might also be related to your problem - failing hardware that will even fail to report its own model.

The processor model, printed on top of the chip, can be a quick way to identify the family of Raspberry Pi. Each model of processor can be identified by reading the first set of letters and numbers after the Broadcom mark (see photo and table below – your Raspberry Pi might also have BCM as part of the prefix to the label).
Other easy-to-identify components include oscillators (cylinders or boxes typically marked with X or Y), transformers (T), diodes (D), and relays (marked as K). Now look to see if the board has a fuse. Fuses are often clear …
Those are plain multi-layer ceramic capacitors and are bipolar, or rather non-polarized.. The reason you are getting odd results is that you probably measure the capacitance while they are soldered into a circuit. This means that you have a number of unknown devices in parallel to the capacitor, so the result can be pretty much anything.
