Hi

First time poster that needs help plz

Put a new ssd hdd into my computer and everything was fantastic until I decided to tweak a few things.

After reading online I noticed the hdd was running in ide not ahci.

I changed it and rebooted and all was fine.

Did a few firefox tweaks and rebooted a few more times then computer wont boot at all.

Push power button and fans come on but no action, and because you cant tell if the ssd is doing anything I put a new hdd in so that i could feel if it powers up but no go

Any ideas?

Welcome,

Assume this is a desktop. Do you get any of the POST beeps? Did you remove the CMOS battery for a minute and then replace it so the system would reinventory the connected devices [new HDD} and adjust? Does the HDD have anything installed on it? And, is it compatible with the system hardware?

Keep us posted

You can see AHCI as the language which the controller uses to speak with the system. The disk can't see if AHCI is being used or IDE emulation. If you use AHCI, all Serial ATA features are available, while you don't need any drivers specific to your controller.

To actually use AHCI, the OS (whether that's Windows, Linux or even Ghost) has to have an AHCI driver. Windows Vista and 7 include the driver, but don't install it if the boot drive's controller doesn't have AHCI enabled. Similarly, the IDE driver doesn't get installed if the IDE controller is disabled. That's why you can't just toggle the setting in the BIOS on an already installed Windows system.

 

Pay to reinstall win7 or change the setting back to IDE

Might be a memory error and your PC is stuck. You can reset the error by doing a power drain procedure. No guarantees but no harm trying. These steps were sent to me by an Acer support tech when I can't boot my PC during a restore process. It worked for me but may not necessarily work for you but it's worth a try. It's very easy.  I will copy-paste the steps below:

 

1.Turn off computer and unplug power cord. 

2.Disconnect everything except monitor, mouse and keyboard. 

3.Press power button and hold for 30 seconds. 

4.Plug power cord back into computer and press power button. 

5.Check front panel LEDs (lights) on bezel (front face) or optical drives and listen for power supply fan. 

6.If LEDs are on or power supply fan starts spinning, watch for boot screen on monitor. 

7.If computer begins to start, turn it off. 

8.Reconnect any external devices. 

9.Press the power button and make sure the computer starts.

The immediate symptom is that a file needed to start Windows has been corrupted. It is entirely possible that a repair of the Windows operating system will correct the problem; HOWEVER, the hard drive itself may be the cause of the problem in the first place. The hard drive may be wearing out. This does not mean that the files on that hard drive are not accessible. 
 
There is a very simple (to computer guys/gals) old trick to get to these files. You remove your hard drive from your computer and add it as a second drive in another computer. Given that all computers involved are running Windows XP, there should be virtually no problem in your drive becoming readable. It will be there in "My Computer" as a second hard drive. 
 
At this point, your personal files should be accessible. 
 
One may ask, "If her hard drive is so bad that it can't run Windows, why would it magically work okay in another computer?" Valid question. Here is the answer: The hard drive in this case has only become partially defective. The defect is in reading the most used area of the hard drive: the Windows operating system. The personal files are not being continously accessed as Windows is and that physical part of the hard drive is likely still okay. 
 
Once this is all straightened out, perhaps your brother would be kind enough to partition your new hard drive into two virtual hard drives: one for the Windows operating system and the other for your personal files. In that way, should Windows ever go bad again, you are able to reinstall the operating system all over again without endangering your personal files. That's how I have my system set up and even though I have had computer and virus and other problems, I have never lost a bit of my personal data.

The boot problem sounds like there might be a power supply problem

The sometimes powering of HDD could be the motor voltage missing

If not the supply check the connections. Intermittent problems are the hardest to identify
