Hello, I recently dropped my laptop, and it shut off upon impact. Powered back up fine. All seemed OK. But the problem I am now having, is my CPU won't go over 0.90GHz. it's been that way since it happened. Expect for today, it was running full speed all day, like it did before the accident.  But, my laptop RAN out of battery and went into I believe, Hibernation, and when it booted back on, it was back to being stuck at 0.90ghz. The power setting is on high performance, and I clean the dust regularly, and by holding the fan from spinning when I air dust it. I tried (1) Rebooting (2) removing the battery and rebooting, hoping that my old battery might be the issue. But sadly, It is running still at less than half speed.
This laptop specs are:
Acer Aspire 4339.
Win 8.1 pro 64-bit
Intel Celeron P4600 Dual core 2.00GHz
I can list any more specs if needed. I am not sure, but I am hoping this laptop can be saved. I read ELSEWHERE online, someone had a similar problem and it was caused by the "thermal paste".
I knew when it was running slow after it dropped, that that had to be why, but today it was running speeds of 1.9GHz for me all day, and worked just like it used to. I look forward to reading if there is or isn't anything I can do to fix this issue. TY in advance for anyone who donates their time to read and/or posts replies.


    Have you checked your CPU temperature since the incident?  It's possible that the cooler has been knocked loose or damaged, causing the CPU to throttle back to prevent overheating.  You can check this with HWMonitor - http://www.cpuid.com/softwares/hwmonitor.html - which will also monitor your CPU clock speed and show min/max per session, so you can also use it to keep an eye on WHETHER your CPU is "sticking" at that speed or whether it does ever go to full speed.Hello ty for reply. I ran CPUID, and while it was sticking at 0.90GHz, it was SAYING the CPU cores were at a temp of 114-116F, then the PC locked up (never happened this way before), so I had to force shut down. When I powered it back on, the CPU's were running at 1.97GHz again, and the tempes were in the 1127-135F range.  That seems extremely Hot to me, is this a bad thing?

**EDIT**
The CPU is running fast again now.  Not sure how long it maintain this and go back to 0.90GHz. It never did this before I dropped it.I see a trip to a repair shop in TylerDoom's future.
Agreed....he should also stop using it til then.Does this sound like anything in particular to you all? Maybe the fan/heatsink, or mobo? I would prefer to back up files and attempt to repair myself if I could narrow down PARTS to try and replace. I am a beginner with pc repairs, but this laptop is old enough that I wouldn't mind giving it a go. If your 1st priority is the data remove the HDD and get an external enclosure for it...hook it up to a working desktop and grab your files.

As far as working on it it's likely the fan and or the CPU have gotten dis-loged causing the overheating.
If your gonna do it yourself i suggest looking up some videos on dis-assembly of that model...they can be tricky.
