Compaq Presario cannot start, short beep then long beep

[Sidiq]

Hello everyone, I would like to ask a question about my desktop PC: Compaq Presario CQ3320L

When I bought it, there was no problem and everything seems very well even though it was in used condition. But, after some time, the computer cannot start and beeping: short beep and then long beep.

I tried so many things like swapping the memory, cleaning them, et cetera then the computer finally booted up.

That did not go well for a long time actually because then the computer hasn't able to start and it only shows "No Signal" in the monitor along with short beep and then long beep.

I would like to buy a new memory RAM if the problem is really the memory itself but I do not know the exact problem so I would like to ask this question to make sure that I'll buy the right thing.

Thank you and have a nice day!

The HP specs page for this model shows it coming preloaded with Red Flag Linux.  So, did it have Win7 on it already when you bought it?  Or did you install Win7 yourself?

The presence of Windows on a Linux PC complicates matters because that means that there are most likely no HP drivers for this model -- and that forces you to rely on the drivers MS installed, which might not work all that well.

As to the beep codes, if the CapsLock key is blinking or there is beeping, read this HP information on the likely cause of the hardware failure based on the blinking or beeping patters.

For desktops, this HP thread describes the different blink and beep codes: https://support.hp.com/us-en/document/bph07107?jumpid=reg_r1002_usen_c-001_title_r0001
--------------------
To determine the cause with hardware failures, you have to be able run diagnostics. We have no way of accessing your PC from here, so we can not do that for you. You have to do it yourself.

You do this by pressing the Esc key repeatedly when rebooting and then, when the HP Startup Menu appears, selecting Diagnostics (usually F2) and letting it run.

If it is NOT possible to run diagnostics, or if that does not work, then there is NOTHING more you can do by yourself -- and there is NOTHING we can do because we have no way of accessing your PC from here to run diagnostics or repair hardware.

You will need to have the PC physically examined in a service facility by folks that can run their own diagnostics to determine what is wrong with it.

If your PC is no longer under warranty, then it will cost you up front to have HP examine your PC. If you want to do that, you will have to contact an HP Repair or Service Center to see if they can examine the PC to determine the cause(s) of the problems, if it can be repaired, and an estimate of the repair costs.

Since you live in the U.S., here is a link to the HP Service Repair Centers:

If that link does not provide the results you want then use the main HP link:

Good Luck

Thank you very much! I'll try what I can do.
