Having problems with your HP Compaq Business Desktop dc5750 ?

Desktop turns off and a flashing red light appears

\015 I have an hp compaq d330 desktop that had a 300w power supply in it that got fried during a power serge. I replaced it instead with a 400w power supply, a motherboard with the same model, and 506MG of ram. It was functioning fine for 2 days but after that it turned off every 30 minutes to an hour and a flashing red light appears.\015

Answers :

Sounds like you need to reseat the processor and heat sink, and use some good quality thermal paste.
\015\012If a reseat dosent do it, test the power supply, ocasionally they will be bad right out of the box, it is rare, but it happens.
\015\012Also check the MoBo connections, and make sure all fans are connected powered up and spinning, people often miss reconnecting something when swapping motherboards.
\015\012Hope this helps!!
