Solved PC froze, used Power button to close, now can't boot up

Specs: Windows 7 Home 64 bit, 8GB Ram
Can't reboot Windows 7, HP P7-1234. A week ago, I had a screen freeze up while in Firefox unexpectedly. I could not close it and it seemed as though the PC locked up. I tried Ctrl, Alt, Delete, but that didn't work either. I left it for awhile, hoping that it would just clear itself up, but it didn't. At that point, I used the power button to shut the computer down. I waited a few minutes, then rebooted. The boot began as I normal, then switched to a black screen with the usual statement that the computer wasn't closed down properly the last time, so chose the start up repair or normal startup. I clicked start up repair, and went through the usual repair process. Nothing seemed unusual up to this point. I've done this before. When it supposedly finished the repair, the computer attempted to reboot. It got as far as the "Starting Windows" screen, then it just stayed there. It didn't continue any further. The first time this happened, I just left it alone and figured that for some reason it might be taking longer then usual after the start up repair. But, then the screen flipped back to the black screen with the message about my computer not having been closed properly the last time and once again giving me the two options to continue. I then tried to continue by picking the start normally option. It did the very same thing. I went through this several times and finally used the power button again to shut the computer off. I tried to boot again, but this time into Safe Mode, but that didn't work either. I booted again and tried to enter the BIOS, just to make sure the BIOS was still intact. While the BIOS on this HP PC looks a little different from others I've seen, I went through it and it all seemed to be fine, so I closed out of it. I also tried to revert to a restore point, and while it performed that operation just fine, it didn't solve the problem. I haven't attempted anything further with it, because this is a little over my head, so I was hoping that somebody here might have had this happen to them and could offer me a solution. This computer has been working perfectly up to this point, so I must admit that I was a bit stunned when this happened. I regularly run Norton 360 security and also MalwareBytes and Glary Utilities for other maintenance. I also keep all of my programs up to date. I'd be surprised if I caught a bug, but then nowadays anything is possible I suppose. I could really use some help with this. For the time being, I am getting by with my backup computer. I was hoping to upgrade the computer that won't boot to Windows 10 when it is released on July 29th, but I really need to get it up and running before I can do that. Thank you.

The on-board diagnostics may not be as comprehensive as the drive fitness software and could have missed the problem--assuming it is with the hard drive.

If you want to attempt a complete recovery/reset you may not need disks. There's a good chance there's a restore partition you can boot to directly. You'd need to check the manual to make sure.

Long shot but easy to try:

Turn off and remove power. Hold Power Off/On button in for at least 20 seconds, to discharge the motherboard components before putting it on again. It has been known to "unstick" computers at odd times.

Always pop back and let us know the outcome - thanks

It could be faulty RAM stick. It could be RAM stick contacts are tarnished (minutely, not visibly), try popping out the memory sticks, cleaning their contacts with a clean soft pencil eraser, then popping them in and out 4 or 5 times to burnish the socket's contacts also.
If this does not work, try running one stick of memory at a time, and then trying the other one. if neither one makes a difference, it is probably not the memory, if one works and the other does not, replace the memory as a pair.
If it is not the memory, it probably is the power supply that is going and is marginal in safe mode but not able to run your graphics at full resolution once the driver begins to load in normal mode. It is very likely that the power supply needs replacing.

You have to be a little bit crazy to keep you from going insane.

Or harddisk problem, since you had this "repair..." before. It may have come to a point where repair of files is not possible anymore.

I'd suspect a hard drive problem too. Go to the drive manufacturer's site and see if you can download a drive fitness test in the form of a bootable iso so you can create a bootable cd. Then boot the HP with it and run the tests.

As an afterthought, the HP might have its own drive diagnostics installed on a separate partition on the drive. If that is still functioning you can see what results it gives. You'd access it though one of the F keys when starting the computer. You may be able to get to it through the bios setup key. You may need to consult the manual for specifics:

Thanks for all of the responses. Hope I can address them all.

I haven't tried Derek's answer yet, as that the computer has been shut down for a week. I will attempt another boot and then a power down using the power button and will report back on that.

As for my previous comments

One of the things I was able to run was HP's diagnostics. I expected to find something wrong from that, however, it reported that everything checked out fine. There were no issues with HDD, RAM, drivers or anything else. If it had at least found something, that would have pointed me towards a possible fix, but to the contrary, it left me wondering what the problem could be. After I bought this computer, I swapped out the PSU for a Corsair Modular PSU that was a little heftier than the 300W PSU that came with the computer. The new PSU has been performing just fine as well.

Haven't done it recently, but I regularly inspect the inside of the PC for dust and will used compressed air, only as directed, to clean it out if necessary.

I haven't tried Fingers' suggestion yet regarding the RAM sticks, but I will give that a shot and report back on that as well.

I should mention this as well. After battling with this last weekend, I went so far as to consider reinstalling the OS. Naturally, you don't get an install disks from Microsoft anymore. However, about six months ago, I downloaded an Microsoft approved copy of Windows 7 Home with SP1 from Digital River in order to reinstall it on a laptop that I had wiped clean. It worked perfectly on the laptop, with no issues, so I decided to pop it into the PC's disk drive and boot from it, and "if" it permitted me to so, reinstall or repair the OS from this disk. It did start the usual boot leading up to an install, but then a message stated that this wasn't the same OS that came with my computer. Obviously, I knew that it wasn't "the same" thing that HP might have used, but it is the same OS on my PC nevertheless. Still, the message concerned me since I wasn't anticipating a problem, and didn't want to create a new problem. So, I just backed out and decided against that plan.

The other suggestions I was given didn't work in my instance, and I knew that, in the end, I was going to have to get to the Recovery partition somehow and just return my computer to it's original condition. That is what I finally did. It's a pain in some respects, but not all that bad. For one thing, I always store all of my saved files on an external drive, then place short cut folders on my desktop to access my work. That way, no matter what happens, I could always just plug the external drive into my other computer and keep on working. That leaves only having to reinstall programs, which is easy.

After restoring everything, I did notice some continued issues with my network and router, which I expected. I'm not a network genius, but I'll figure it out. The important thing is that my computer still sees the network and I can still get online. For some reason, I can no longer see the Network Map, yet all of my networked peripherals are working. But this is an issue for another day.

I should mention, that I was able to run an HP Diagnostic of my computer which indicated that all the hardware and internet connections were fine. I ran all of the tests and they all passed. The problem had to be software corruption, I guess.

Thank you and everyone else who offered suggestions and advise.

The restore/reset would have had drivers for all the original hardware but if you changed any of it then the problem may be a driver issue. You may want to check in device manager and see if any problems show there.

You're right. Under Network Adapters, the 802.11n Wireless LAN card and the Realtek PCI GBE Family Controller are highlighted. I noticed that earlier, but was so involved with other things that didn't go back to look at them again. If they're showing then there's an issue with each of them. What do you suggest I try? Should I delete them, reboot and let Windows find and reinstall the drivers, or is there something better that I should try?

Thanks for hanging in with me on this one. It's sort of the very last glitch.

If you click on the highlighted item it should give a brief explanation of the problem but it's probably drivers. Did this hardware originally come with the computer or were they added later?

You can have windows search for a driver but if it can't find one you'll need to download them either from the support page for your HP or from the card manufacturer or supplier.
