Narrative:

On takeoff when first officer called for 'gear up' I tried to pull gear up but; lock was still in place. At that time first officer noticed a 'ckpt ovbd' cool status message. A few seconds later we got a 'wow overboard and inboard' caution messages. At that time got the qrc out and got to the required section. First officer took over communications while I did the QRH; we climbed out and cruised at 200 KIAS to 10000 ft. Noticed we had a pressurization problem as well but we were already low altitude for this short flight; decided to descend to 8000 ft. First officer and I agreed with the QRH possible lack of braking on landing; should [advised ATC]; and then first officer did at that time. While I was in the back briefing the flight attendant; first officer got vectors for visual xxl. I gave the flight attendant her [duties]; I decided it was best to have the passengers brace due to the braking unassured on landing. On short final I dinged the flight attendant to let her know landing was imminent; to start calling for brace positions. Landing was normal; complied with QRH on landing and manually extended the ground lift dumping and spoilers. We then came to a complete stop and had the firetrucks do an inspection of the landing gear just in case on any unforeseen malfunctions or parts missing. Everything was normal; we then taxied to the gate as normal. The maintenance personnel suspected there is a problem with a flight computer in the aft equipment bay. In the air I assumed it was a squat switch problem of some sort but maintenance says it looks like it's a bigger problem than that; nothing official at this time of reporting.
