I have the Projector hooked up to a PC, the projector loads up and does everything as normal. But after 3 - 4 minutes of working perfectly the projector shuts off and powers down. Nothing has changed on the settings or how its wired. Any suggestions on what I could possibly do.

Hi, Cutting out after 5 minutes sounds like an overheat fault. On every projector will be a filter that is user serviceable - it will most likely be blocked up with lint. To Clean - locate the filter & remove carefully. gently brush the lint & dust off the surface of itusing a soft brush or vacuum cleaner on its lowest seting. Try not to puncture the filter element. reinstall.
Check the cooling fans. If they are not rotating the Projector will not start. Did the lamp explode? If it did a bit of glass has lodged in the cooling fan and stopped it from working. Hope this helps.
just in case it is overheating, blow out any dust with canned air and make sure the fans are working. also, keep anything from blocking the vents. if all that is done and it still shuts down, you have a power supply that needs replacing.
It sounds like it is overheating. Are the fans all working? If so, try opening the casing and blowing all the dust out with a can of air from Staples/Office Depot. If the fans aren't working you may need to replace them.
1-SWITCH YOUR PROJECTOR OFF. 2-CONNECT EVERYTHING AS NORMAL CONNECTION. 3-SWITCH DOCUCAMERA ON. 4-SWITCH YOUR PROJECTOR ON. 5-CONFIRM THAT INPUT OF PROJECTOR IN RIGHT INPUT TO CAMERA. 6- CONFIRM THAT CAMERA CABLE IS GOOD BY PLUGING IT IN VIDEO INPUT OF ANY TV.
With most projectors there is a foam air filter behind a grill that is the opening to the cooling channels. A fan ensures air flow to cool the lamp, etc. This filter prevents dust from gumming up the works (and depending on design) may prevent dust getting into the optics. As the filter gets dirty it gradually cuts off the air and at some point a protective circuit kicks in and turns off the lamp.
If the projector is on you will feel a stream of hot air coming out of the exit vent. Projectors vary in terms of amount of air flow, so its difficult to define what is normal for a specific model. However, you can simply hold a hand in front of the vent and see if there is air flow (It will be hot air so, careful). If there is a "good" stream of air things are fine, but if only a very light flow is felt the filter may be dirty.
If the filter has not been cleaned or replaced recently make sure the projector is turned off and cooled down then take off the inlet cover and remove the filter. Clean or replace per the instructions for the projector (and periodically as defined .. but taking into account the operating conditions). Once cleaned turn on the projector and feel the "normal" air current for future reference.
Heat is one of the major causes of projector failure, so make sure cooling vents (inlet and outlet) are not obstructed and filters are kept clean
