Hi Ron66 – Welcome to – Geeks To Go –

Need more info on PC – so I can do some research – Need to know –

(1) Manufacturer Name – Compaq Model Number
(2) Type – [Laptop] – Desktop] – Tower
(3) Motherboard – Manufacturer & Model Number
(4) Video Card – Manufacturer & Model Number
(5) Monitor – Manufacturer & Model & Age –
(6) How much RAM is installed
(7) Power Supply – Description – Wattage Rating – Manufacturer & Model Number – Both Old & New Supplies –
(8) Reason for Replacing – Give all details - Did you have to remove Motherboard in the replacing process?
(9) Operating System – Version & Service Pack installed
(10) Is this an Upgrade from WIN 9X
(11) What – Anti Virus – is installed
(12) Do you have any Firewall installed
(13) Do You suspect any Virus
(14) How old is Computer
(15) Any Other Upgrades – (Motherboard) – (Video Card) – Power Supply) – (Hard Drives)

Most of this info should be contained in your Manual or other PC Documents and by viewing your – [/b]System Information[/b] -

I realize that you cannot run PC to observe the – System Information Folder – at this time, but here are the instructions – anyway . . . .But first – Try disconnecting the Power Supply Connectors & reconnecting them & verify – proper orientation – proper seating – And note any differences between the – Old & New Supplies – regarding the Power Connectors – And tell me about them – Compare the – Color Coding of wires – between the – Old & New Power Supplies – Please Note – that at one time – The 20 Pin Connector was not keyed – along with some of the other Connectors – depending on Age of Motherboard – Also some Motherboards contain an additional – Auxiliary Connector – Compatibility – between Motherboards & Power Supplies – Are not a given -

Also – I think – that Compaq – at one period of time – had used – Non Standard Power Wiring practices – So depending on Age & Model Number – (May or may not be a concern) –
________________________________________________________________

Instructions to Open – System Information Folder –

(1) Click on – Start Button –
(2) Move Cursor to – Settings -
(3) Highlight – Settings – View Dropdown Menu
(4) Click on – Control Panel – On Dropdown Menu
(5) Open – Administration Tools – Folder –
(6) Open – Computer Management – Folder –
(7) Expand – System Information - Folder – (By clicking on the (+) on Left side of Folder –
(8) Open – System Summary – Folder & wait a few seconds – for Summary to appear –
