When I start my PC and it does the whole DETECTING IDE Drive's thing, It takes about a minute. It finally see's that i have one hard drive and two cd drives. Then it will start booting like normal but when it gets to the part where the windows loading screen comes up. It says DISC BOOT FAILURE.. PLEASE INSERT SYSTEM DISC. So next time it started up i tried to get to the windows repair thing but it will load up everything and right when it gets to the part where you can select if you want to either install windows or repair an exsisting installation, the PC just shuts off. What is my main problem here. Would the power supply cause these kinds of issues or am i just going to need a new hard drive?
