Reseat the memory and check all cables. &nbsp;I have several d530s; sometimes reseating the memory does the trick. &nbsp;Others require a replacement motherboard. &nbsp;Is it still under warranty?

Hmm, time to call the OEM. &nbsp;If it's still under warranty they'll replace the MB, PS, and/or CPU or all. &nbsp;Usually things are happy again after I replaced the MB.

Power On Light

A desktop computer is a personal computer designed for use at a single location due to its size and power requirements, usually by one person. The most common configuration has a case that houses the power supply, motherboard, disk storage (usually one or more hard disk drives and optical disc drives); a keyboard and mouse for input; and computer monitor and printer for output. The case may be oriented horizontally and placed atop a desk or vertically and placed underneath or beside a desk.
