Windows 7: Sluggish Win7 on New Build

Sluggish Win7 on New Build

Hi there,

I recently installed Windows 7 Home Premium 64bit on a new build and it is running very slowly. Slow to boot and wake up. Struggling to run multiple programmes. Slow download speeds. Slow everything basically. I don't know what the problem may be as I haven't got a very detailed knowledge of computers and diagnosing problems.

Build specs are:

450w psu
8gb 1333mhz (2x4GB) DDR3
Gigabyte GA-H67MA-D2H-B3 (Intel H67)
Intel Core i3 2100 (2x3.1Ghz) 3mb
750gb Sata-II 16mb HDD

My wireless adapter is NETGEAR RangeMax Dual Band Wireless-N USB 2.0 Adapter WNDA3100

All windows updates have been installed.

Any help you can offer is much appreciated

Thanks in advance,

1). Check for malware
2). Is your copy of Windows 7 legit?

Checked for Malware and haven't found anything and yeah my copy is legit. Might boot into ubuntu and see how it runs, should give me an idea about whether it's Windows which is causing problems or the components?

When you installed windows did you download your drivers from Gigabyte's web site? Also, download and run the diagnostic program from your hard drive manufacturer. Also, does your bios show all of your ram?

This may or may not have anything to do with your issue, but I can't help but think your 450W PSU is pretty weak for the kind of system you have.

Did you build the computer yourself? Is the BIOS up to date, and has it been reset to default settings? Did Windows find drivers for all devices, or are any unknown devices listed in Device Manager? Have the chipset drivers for the motherboard been installed?

Thanks for all your help so far! I ran a diagnostic program from WD and the report came back with no errors whatsoever so that's fine. All RAM is detected by the Bios and I've got all the drivers downloaded from Gigabyte that I need.

There are no unknown devices in Device Manager so everything seems as it should be. Chipset drivers also up-to-date.

Could it be just a case of not getting enough juice from the PSU? Maybe I should pick up a cheap SSD and a 700w PSU and install Windows on the SSD while using my current hard drive just for storage.

What do you think?

What do you think?
Your system specs say you are using integrated graphics.

If that is so, I seriously doubt that system ever uses 200 watts, let alone 450 watts.

So, unless it is outright defective, I'd doubt if the PSU is the problem.

I'd be inclined to check what processes are running when it is "slow" and to find out about RAM usage. And take a look at what you have running at startup via msconfig.

I would also recommend using msconfig/Start Up. I only have 3 checks. Make sure you have your anti virus checked. Many times when adding things to a computer they all end up in the boot at start up and don't need to be. I would not use sleep mode until you get your slow problem fixed. When and if you add a video card you will need a bigger power supply.

Slow is a very relative feeling. I assume you came from a much slower CPU and expected this build to really zoom. Fact, however, is that your performance is by and large ruled from the disk and the line speed you have with your ISP. The integrated graphics is no barnstormer either. So relative to what you had before, there is probably not a big change.

There are two things you can do to improve the situation.

1. Install the OS on an SSD. I suggest you get a 60GB model from a good make (OCZ or Intel). Sata III models are preferable but Sata II may do and is cheaper. This may give you some guidance: SSD - Install and Transfer the Operating System

2. Check with your ISP about a better line speed. I would go for DSL 6000 at least. That will improve upload/download speeds but not webpage access speeds (those depend on the number of hops).

You can use your "Resource Monitor" to have a better look at what's consuming your resources.
I also like
sysinternals Process Explorer. A well regarded utility.
