Can't pinpoint slow bootup bottleneck - X64 Win7 & Win8 Pro

July 19, 2013 at 08:01:29
Specs: Windows 7
Acer 7745G Laptop
Intel i7 1.73
12GB RAM
256 SSD & 1TB HDD

Takes 3-5 min from post to desktop. Runs slow as heck most of the time but only at approximately 10% CPU, 12% RAM, and 23% disk usage according to task manager. Applications take forever to start and stop responding often for long periods of time. Disk activity seems constant. I have swapped out primary hard drive. I have done clean installs of both Win 7&8. I have disabled unnecessary services. I am running out of ideas. Seems hardware/driver based maybe?..., but not sure how to nail it down.

Any suggestions?

Thank you!!!!!

Check SATA, SSD/HD, and boot settings in BIOS.

Boot settings are default, and in correct order.

It does perform about 30% better with secondary hdd removed, but still significantly slower than before. Whenever I reinstall sata drivers, it improves for about 15 min, but then slows again... Like it's losing the drivers or something. It's weird.

Also just noticed moderator changed my title/subject. The issues begin at boot, but persist throughout normal operation.

I replied above... All latest drivers for all hardware available from acer have been installed. All windows updates installed as well.

Does this also happen, when disabling network connection?
Or maybe, does the CPU usage increase when disabling network connection?
Is there a third party firewall installed on that computer, and if so which?
Is there a third party Antivirus software installed, and if so which?

IN BIOS, is AHCI mode (full SATA speed) active?
Is it any better when the laptop is plugged in?
Try starting it with the power cord plugged in but the battery removed.

AHCI enabled- Power source has no noticeable effect on performance.

Disabling the network adapters helps significantly (primarily wireless connection)
No major CPU usage changes either way. No third party firewall, and I use Avast's Endpoint Protection Suite (not plus).

Does this point toward a driver or service/process issue?

Thanks!

So while disabling the network adapter helps significantly, there is most likely a program, maybe a virus or trojan, that connects to it's home.

So reenable the network card, open your favorit browser and browse to the web configuration interface of your router.
Hopefully you router has a statistics page, where it shows the current network activity.
If there is a huge data flow, while you do not run any program, that connects to the internet, there is an unsolicited guest on your computer.

In that case I suggest to download an antivirus livecd and check your computer, by booting from this cd.

Did a boot scan with Avast for starters (blank cds were at work). Found a few things that didn't show up under regular scanning. Removed them. No stats on wrt54g router available as far as I could find, but network desktop gadget "should" tell me the same info. All activity with programs closed is <1kb/s up or down, so I think that particular issue may be solved. I'll give it a day or so and report back. I just don't understand why I got the same problem even after a fresh install. (currently using what may have been a cloned image from before) Correct me if I'm wrong, but "virus" .exe files are harmless if never "clicked," or run, right?

Thanks again for your assistance with this nagging issue!

Yes, you're right. As log as you don't touch the infected .EXE files, they are harmless.
Anyway, it could be a virus in the browsers cache, which come up, when starting the internet browser.

Btw.: If you install windows from scratch and theoretically there is no firewall and antivirus installed so far, it takes less than 2 minutes without browsing the internet, and you system gets infected. I tested that in a virutal environment and indeed, less than 2 minutes and bang, I've got 4 new viruses or trojans.

Haven't tested this on Win7 but on WinXP.
And yes, I'm serious !!!

It may have changed a bit on Win7, but I doubt on that.
