I have a Gateway GT5458E that is intermittent. Started doing a black screen (no video) about once every three weeks. Has progressed to once every 5 minutes; after about 5 weeks.
How to troubleshoot? Doesn't seem like software to me but I don't know. Probably a bad component in PS or motherboard. I'll check the PS voltages once the box fails. Am thinking freeze spray might help locate the component. Might also be worn out heatsink paste?
Any thoughts as to how to eliminate the software? How to go about finding the component?
BTW, it's not the monitor. Checked by substitution.
