Windows 7: Windows boots very slow and runs slow after booting

Windows boots very slow and runs slow after booting

Hello 7forums. I have a problem with my Windows 7 Professional (32bit). I'll try to explain everything in detail.

PC specs:
Processor: Intel Core 2 DUO CPU T5800 @2.0 GHZ
Installed memory (RAM): 2.0 GB
System type: 32-bit operating system
Yesterday I was using uTorrent to download some files (24 gigabytes +). It was downloading at a speed of ~7-8 Mb/s. During the download I noticed that the PC was running pretty hard and I checked in the Task Manager for processor and RAM usage, noticing that the processor was used at around 50% of capacity but RAM memory was used at 1.9 GB, that's around 98%.

I restarted the laptop and run the download again. Memory usage was about 1.4 GB. Then, I tried to open Firefox and go check something on a website and everything crashed. I unplugged the laptop (n00b way of solving things) to shut it down and then started it back. At this point I noticed that it took like half an hour to boot and show desktop. Also, everything was running extremely slow.

I inserted my Windows 7 disc and ran through the `Repair Windows` wizard. I left it like that for about an hour and it was just telling me `Attempting Repairs`. I stopped it at that point and then re-installed Windows by formatting the partition.

Now, when I start the laptop it takes like 5-10 minutes until it shows me the desktop (before was 1 minute). Also I noticed that everything runs extremely slow. All the drivers have been successfully installed (except for 2 USB ports).

If I keep my Windows Task Manager opened to performance & memory usage when I try to do stuff on the laptop, it shows me 0% CPU usage when the laptop has a `crash moment`. It simply crashes (stops doing anything) while CPU is 0-3% used and RAM memory around 700 Mb.

I attached a photo with one of this `crashes` where I wanted to visit a page and Firefox was just Not Responding while CPU was at 1% usage.

Also, after some time it just begins to work okay.

Any hints on this ? Help would be greatly appreciated.

Hello and welcome abyssal Mate for very starters I would be running some malware scans the two I would run would Malwarebytes and SuperAntiSpyware. and

Next would sticking another 2GB of RAM what you have got is absolute bare minimum.

Plus some specs on your system would be helpful

Well thanks man. I'll run the malware scan.

And about my PC configuration, I find it quite good for what the laptop is meant to do: surf the web, watch a movie and make some C++/Java/php quick scripts from time to time. Actually before this my PC was running extremely well.

I just think there's something that makes my processor stop working for like few seconds from time to time. (sounds foolish, I know).

Ok mate do both scans and just how old is this machine as the intermittent stopping of the CPU sounds like it may be a heat related problem.

You can check that by running Speccy Speccy - System Information - Free Download its free and takes very little space and time to run.

Ok, Speecy shows my CPU temperature is around 60 degrees Celsius. I'll just try to look into the laptop and maybe clean it out a little. Thanks, I'll get back with more updates.

Ok mate if you are confident in taking the bottom cover off then it might jut down to a lot of crud in the small "radiator" on the end of the heatpipes. If I knew what model your machine I may be able to find the repair manual for it to give you a step by step guide especially if it is a Toshiba.

But if you are ok with doing this just be careful to keep the tiny screws safe and keep an eye on the order they come out as there are usually different length ones.
The temp is a little on the high side and I would hazard a guess at crud being your problem there as the CPU has an inbuilt thermal shutdown (you can sometimes set this shutdown temp in the BIOS) Make sure you clean the fan and whatever you do "ground" yourself before touching anything under that cover. You probably know this already but I am just making sure

Thanks, I've done it before, I'll do it again.

Please note that by `crashing` I don't refer to shutting down. It just doesn't do anything for 5-6 seconds, then comes back. This also makes scanning almost impossible, because it scans a number of files and then it stops for 5-6 seconds, than scans another for just few seconds before stopping again.

Any other hints are greatly appreciated.

Ok mate dd those scans come up with anything then? would be very surprised if they didn't.

What you describe then might not be a heat related problem but will not hurt for a bit of a clear out.

As an afterthought you could try a memtest for any problems with the RAM

Memtest86+ - Advanced Memory Diagnostic Tool you will need to make a bootable disk and set the BIOS to boot from the optical drive and it does take a fair time to do and I think they recommend at least 7 passes - best left running when you go to bed.
If you need a disk burner then ImgBurn is good for that .

The Official ImgBurn Website < just a tip but be very careful when you see free sans offered for whatever and only then when you know for absolute definite they are ok - but there isn't many that I would run if any.

Another if you haven't got it already for cleaning up the machine is CCleaner - excellent tool free and just about everyone uses it.

CCleaner - Download < download form piriform

Let us know how you go.

In addition to John's excellent suggestions I'd want to run a Clean Boot, make sure repeat errors are resolved from the logs, utilize System Resources to find Solutions to Problems from these Troubleshooting Steps for Windows 7.

Okay, I tried scanning but this is impossible. Not only that it takes too long due to the processor refusing to do anything but it also restarted my PC (half and hour to boot). CPU stays at 0% while it should be doing stuff.

I guess there's a hardware problem. I may try to run some scans through network from another PC.
