I know this doesn't have to do with receivers but you guys would be the only people that might be able to help me. I built my own computer in april and have had problems with the power supply actually I've gone throught 4 different power supplies (2 compaq, 1 Enermax), 1 since April (Antec). The power supplies last about 2 to 4 months and then just go. I keep getting the same problem I lose any display to my monitor. I've tried 4 different motherboards of 3 different brands (2 Compaqs, 1 ASUS, and 1 Giga Byte), 3 different video cards (all Nvidia TNT2 Pro, GF3 Ti 500, and GF 4 Ti 4600), and 3 AMD processors 1.2GHz, 1800+, and 2000+. All with the same problem but one thing has remained constant and that is my Monster Power PowerCenter CG 500 UPS, could it be that this is sendong bad AC to my power supplies and eventually damages them. I don't know if it has a warranty because I won the UPS when I worked at Best Buy. If it was damaged how should I present this to Monster, how could I prove this to them that it's their product fault, I'm not sure it is myself? Is there some way I could find out if it sending a bad signal to the computer? Any opinions would help. Daniel Smith P.s. I've also tried different hard drive and cd drives, etc but don't think that will really have any effect on the video signal.
