A7 indicates that it is a K7 series - a socket 462. Socket 7's were for the old Pentium 1's and AMD K5, and K6 I,II, and III series of pre-athalon processors. Socket 7 was also the last socket to see Cyrix chips.

Best to remove side of pc and look at the board itself, but it may be a 'socket 7 board for AMD Athlon processors, which are hard to come bye now. The next step up to your mobo would be a socket 754 type for the AMD Semperon, but it's your choice, you can go for any choice of Mobo, as long as you are buying a processor also.

Compaq presario sr1050nx will not power on and the green light just flickers.

I have the same SR1050NX compaq computer with the same startup problem. I suspect this from a code seeded in the system, so performed the system recovery for several times. The problem gradually came back, automatic shutting down with loger interval. I thought the bug is in the recovery system. But the floppy drive in the cmos is disabled without choice to be activated. So, I couldn't perform FDISK at DOS mode. For this computer, I wonder anyone knows how to activate the drive for boot order besides through the setup window.

Thanks very much.

Will a AMD Athlon 64 processor work in a Compaq Presario SR1050NX Desktop? My old processor Died and I purchased one of these off of Ebay, now just want to make sure it will work...

No Donnie, the motherboard for the Compaq Presario SR1050NX won't support an AMD Athlon 64 processor.

The reason why is;
A) The Processor socket on the SR1050NX's motherboard is a Socket A. (Also known as Socket 462)

Hp Support > Compaq Presario SR1050NX > Specifications > Motherboard Specifications >

CPU = Central Processing Unit. Another term used is Microprocessor, or Processor for short.
Look to the right of the CPU heading:
Socket A (Processor socket)

This is the Socket A processor socket used on your motherboard,

You can click on the photo of the Socket A processor socket, to the upper Right, to enlarge.

The AMD Athlon 64 line of processors came out after the Socket A, and used the Socket 939 first.
Then on to the Socket AM2.
(Socket 940 for some models)

List of AMD Athlon 64 Microprocessors,

My computer won't boot-I hear the fans running but nothing else. can this be fixed?

This usually means that there is a serious problem that should be looked at closely by a technician. For example, this could be related to a bad power supply, a faulty or dislodged processor, or even a motherboard failure. I could suggest checking these areas, but it is best left to a trained technician.

On my desk-top presario

HP/Compaq has had alot of power supply issues with this series of computers. Do you have another power supply you can try in this system? If the light is flashing rapidly, it is usually a power supply. Fairly cheap and easy to replace.
