computer in infint loop

I would reseat the video card and the memory.. if that still doesn't work I would pull all your cards out and ONLY install the video card and memory. If you still have problems pull the IDE cables from the motherboard and see if you atleast get video at that point. If you still have problems at that point. You can try and reset your CMOS by either moving the jumper to the reset position or removing the cmos battery for about 5 mins then putting it back in. Let me know how this works. IF all else fails try replacing your processor (if you can)

A few questions,

Is there anything specific that you can think of that may have caused the problem. Like new hardware installation, power outage, pespsi spill into keys, etc.

Use your senses, sight, smell, hearing and touch can all help in troubleshooting the problem. Smell the back of the power supply, does it smell burned? Is the system powering up at all? Is there any lights, audible beep(s), drive sounds etc. Does the power supply fan in the back of the unit spin up? If not the power supply may be blown. Could be something as simple as a bad power switch/button. Is the selector switch on the power supply set to 110V and not 220V the switch can be moved from one direction to the other to select the different voltages. 110V would be for the USA and 220V for Eurpoe and others.

Open the case and see if the CPU fan spins freely. Reseat things and check for burned components on the mother baoard.

AGP video cards have a tendency to ride up in the slot because of the tension caused by the case frame. If it slips up even a small amout there can be a lose of contact with the slot and the system will not boot.

The advice from answer one is all good but sometimes the CMOS (BIOS) battery needs to be removed for more time, maybe even an hour or so. Some mother boards will reset the BIOS if you press and hold the end key while turning on the power.
