I'm posting for a computer that is not my own, so details of history are not always known. (This is my daughter's pc). I believe this may be a laptop we replaced a cracked screen on, but that should not be causing the problems it's having - as the problems cropped up weeks or months later...but I wanted to mention that on the off chance that it is still somehow the culprit.

 

The computer is an HP, says Altec, G62, AMD Turion II P540 Dual Core Processor, 3.00 GB of which, 162GB is free at the moment. Runs Windows 7.

 

This laptop shut down unexpectedly QUITE awhile ago (more than a year ago possibly two) and we weren't able to get it running again. It gave one CMOS Checksum error when we tried to revive it - The note I have here says 'invalid, CMOS reset 502', if that means anything to you. Then it went to a black screen but the mouse was visible - and after shut down a second time nothing came up and the pc would not boot up at all. This laptop was set aside and because of it's age we simply got my daughter a new one instead of paying tech people to look at it, since they couldn't guarantee they could fix it anyway.

 

However - I came upon this laptop in the moving box and being the hopeful type, I plugged it in one last time after pulling out the battery and holding down the power button. We'd already tried that trick a few dozen times so I've no clue why this computer is finally working now. I'd like to get it fully functional, if we can...and if not, her other laptop suits her fine so it won't be a huge loss.

 

The pc had a few issues when it booted back up. It no longer recognized a USB controller - port #3, Hub #2, Code 43.  After trying several things listed in other forums I finally just went ahead and uninstalled the port to get the error message to go away. (which it did..I no longer get the error). We don't use more than one USB regardless. However, all three USB ports ARE working right now despite that error message and despite me uninstalling it. And actually, the pc says we have 5 USB ports when we only have 3..so I really don't know what's going on there. Nor do I care much, as it's working atm. I list that also in case it's relevant in some manner.

 

There was an immense amount of children's games on this pc, and school software, so I uninstalled all the ones I knew she'd grown out of. There is a lot remaining, but I hope to save most of it, if we can.

 

I ran Avast and Spybot as soon as I could. Avast found quite a few things, but they were all tracking-type, low risk items I'm not concerned about ( and Avast fixed them all.) Spybot found one additional thing that it also fixed. This computer didn't see much internet surfing - just games - and mostly from one site that we trust - though I note they use tracking cookies.

 

My question is where do I go from here? I've dumped the recycle bin, and defragmented..which improved the CPU usage very slightly....what is my next step in troubleshooting the high CPU usage that's making the laptop so slow? More scans for viruses/malware? Diagnostics for hardware/software issues? Atm, running software on this laptop is a pain...things take forever to load or lock the computer up for awhile, or occasionally make it so we MUST reboot. Defragmenting one of the drives took hours when it would have normally taken minutes. Updates aren't seeming to 'take' - Windows has been attempting to update itself continuously every time we restart the computer. It usually says it goes through fine, but then it immediately wants to update itself again. (It doesn't SAY it wants to update, but I note the updating icon near the 'shut down' option in the start menu never goes away, and that windows ALWAYS updates itself when we do restart.) So I'm not sure if it isn't working right or if it will just need to update itself for a week straight due to how long this computer has been dead. 

 

Ok, I think that's everything you need to know? Thank you for being kind enough to help us figure this out. It would mean a lot to my daughter. If I can get this laptop running correctly I'm going to surprise her with all those games she 'lost' a few years ago...would make a nice thing for her after the move!  :D

I'm afraid we inadvertently made things much worse over the weekend. It kept on updating Windows and shut itself off in the middle of one such download. Upon reboot it gave another CMOS error and then the blank screen with a mouse. I think if I'd known how to stop Windows from making the updates, it would likely still be running.

 

I wasn't sure if I was going to get a reply from you guys or not, and when I set the laptop down after that, I noticed it made a weird noise. After I did it again I realized something inside the pc itself was rattling around - and was QUITE loose, since the noise could travel from one end to another. This was something I'd never noticed before...probably because it's usually sitting on a desk and stationary...or was until we packed it up. With nothing to lose, no warranty remaining, and something obviously wrong inside of it - I decided to open up the back..really a complicated process for this laptop! And I found a loose battery!! I was really surprised, let me tell you! I didn't realize laptops had little batteries in them!

 

To get the battery back where it needed to go I had to take apart darn near the whole laptop and flip the motherboard over. But with several youtube videos for that exact model, I managed - and I believe I didn't damage anything. Though I can't really be sure. A brand new battery was installed....I figured why put an old one back?

 

And now the laptop powers on, brings up the windows screen - then goes to a blank screen with the mouse. There is no more error screen..and if it could have anything to do with the CMOS error, maybe that will always be gone now since the battery is back in place. But I also can't get into any screen where I could download any software. I CAN get into an esc screen that brings up various options. I'm thinking a system restore is maybe our only option at this point? I don't even know if that would save the laptop. I'd really hoped to get those games back for her, but it won't be the end of the world.

 

My apologies for this not going as smoothly as I'd hoped and I'll refrain from taking apart the laptop again. LOL. Do you have any thoughts as to what I should do from here?

I think your best option is to create new topic in hardware forum.
