Note that the motherboard is an ASUS A8M2N-LA but that HP have more than one style (corresponding to different component populations of the same board and probably different BIOS's too. pin-outs should be the same though....see joelcoolvette's Fiya pst here

Since youre setting up a DSL connection choose Set up broadband connection > PPPoE. You will need the username and password you were given to this account (contact customer service at your ISP for this info). Enter the info and have it remember the password. Click connect. Once Vista finds the connection, it will ask you to choose a network type (Home, Work, or Public). Select the type and enjoy. If the connection fails, recheck your username and password entries.

SOURCE: powers up and cpu fan is racing but no boot,

This may be due to a CMOS mother board battery. I know that some tech or expert say that you can still boot without it but my experience is that if the CMOS battery is below 3.4 volts it may or may not post or boot. This battery is about the size of a quarter usually found at Walgreens or Walmart for about 3.00 dollars.

What is motherboard pin assignment in cimpaq presario sr2020nx


I would start by looking at the motherboard and see what motherboard it is. Most manufacturers get their boards from someone like asus or someone. Once you see the motherboard manufacturer, look for a model number, then look up that and you will easily fnd the pinout.

I have a Compaq Presario SR2020NX. I press the power button and the fan comes on, the green light is bright , the cd drive blinks then stops as if the computer is starting but nothing happens. The fan...


Disconnect the drive and try to boot to the BIOS (usually with F1, F2 or Delete key). If that doesn't work, try removing all cards from the computer (except a video card if the video port is not on the motherboard). If you can boot this way, try inserting back any removed cards to see what hangs it. Do you hear any beeps when the computer is booting (beep codes)?

Hi, Is Asus ATI Radeon HD6450 Silence 1GB DDR3 VGA/DVI/HDMI Low Profile PCI-Express Video Card capable for my Compaq HP Presario SR2020NX? -thanks a lot.


You mean will the Asus ATI Radeon HD6450 with 1GB of graphics memory, work in a Compaq Presario SR2020NX Desktop PC?

Yes.

The Compaq Presario SR2020NX Desktop PC has a PCI-Express x16 expansion slot.

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00757470&tmp_task=prodinfoCategory&cc=us&dlc=en&lang=en&lc=en&product=3245048

{Motherboard illustration and photo are towards the bottom of the page}

Look at the specifications.
Scroll down to the heading - Expansion slots.

Three PCI. (PCI expansion slots)

One PCI Express x16 graphics.

NOTE*
Looking at the motherboard illustration, it is Wrong.
Shows - PCIEX1 (PCI E X1)
According to the specifications it is a PCIEX16 expansion slot. (PCI-E x16)

A PCI-Express x1 slot has 36 contact pins. 18 on each side.

In comparison a PCI slot {White} has 124 contact pins. 62 on each side.

Looking at the photo of the supposed PCI-E x1 slot they show, the black PCI-Ex1 slot is longer than the white PCI slots.

It is a PCI-Express x16 slot with 164 pins. 82 on each side.



The Asus ATI Radeon HD6450 uses a PCI-Express x16 expansion slot.

So you know the graphics card will fit. Low-profile to boot.

Power requirement:
The Compaq Presario SR2020NX desktop computer comes with a 300 Watt power supply.
(Although in actuality it's more like 70 percent of the maximum rated wattage. 210 Watts)

Enough power for the computer, and the graphics card.
ATI graphics cards do not use as much power as a comparable Nvidia graphics card.

Concerned that the Asus graphics card uses DDR3 graphics ram memory, and the Presario SR2020NX uses DDR2 Sdram ram memory?

Don't be. The graphics cards graphics memory runs independent of the computer's ram memory.

Information on PCI-Express,
