Question about HP Bestec ATX-250-12ZD 250w HP Pavillion Zinfandel Power Supply Part 5187-1098 (ATX25012ZD) Power Supply
Whom ever told you too: "Unplug the cpu while holding down the power button".
Is telling you something that can "seriously damage" your cpu and computer.
Or did you mean "PSU" if so there is a particular format to do a Power supply check.
For the proper way use this link: http://h10025.www1.hp.com/ewfrf/wc/document?docname=bph06788&lc=en&cc=us&product=405227&dlc=en&lang=en#N207
Also many other things can cause the problems your having. Could be your motherboard too.
If this does not work, post again be sure to include HP Pavillion Model number and Operating System (i.e. XP, 7 or Vista) that way we can help pin point your system needs. Also have you done any internal repairs lately? Recheck all your connections too.
