Will Clean-Installing My Computer Make It Run Faster?

[Wandering Flame]

Even a little bit? I have a Windows 7 laptop, Inspiron 1545 by Dell. I heard they aren't the best system tweakers and pre-install are sorts of stuff that makes the PC run a bit slow.

What if I clean install my Windows 7, then add all the drivers for my service tag on my laptop, and my programs? Will that make it run even a little faster?

Thanks.

Dell, and many other manufacturers who offer pre-built systems with the OS pre-installed, typically include a lot of bloatware such as Norton and McAfee (which is OK if you want to use either of those AV products, but which can be a pain to remove if you don't). In fact, some of the other bloatware that they insist on installing can be difficult to remove as well.

Providing that you can find suitable drivers, then a clean install will be beneficial. By clean installing, you control what programs/applications are on your system.

Just a suggestion: Don't change out any drivers given by the Win7 installer unless performance dictates it.

MS spent a fortune building drivers for Win7, even paying manufacturers so they would have them in the installer first. Newer are delivered to installer if connected to internet during install, and/or via optional Windows Updates shortly after install.

The Dell Drivers/Apps disk and webpage for your model are useful for any missing drivers or apps, or if performance dictates a changeout, as are mobo chipset and vidcard, Adobe (reader, flash) and Java (runtime, free Ofc) sites.

Hi.

The Inspiron 1545 comes in many flavors. If you could post the exact specs of your model we may be able to get a better feeling of what you should expect.
A reinstallation will only help if you do it differently than your current installation. One (pretty drastic) step would be to tune your installation disk (if you have an installation disk) with vLite. Another (lot easier) action is to uninstall everything that can be uninstalled and that you are not using. Apart from the bloatware as mentioned by Dwarf there are a lot of other programs that you may never use (example: Works).
But use the Revo uninstaller (advanced option). Unfortunately the free version works only on the x86 libraries. If you have an X64 system, you will have to spend $39.25. The advantage of Revo is that it deletes all the leftover files and registry entries that the program uninstallers leave behind.

Flame,

I have the exact same model you do (typing on it as we speak).

I purchased my box in November. Tried to go on the OEM install for a month or two - seemed OK until I started getting Explorer errors. Finally got so bad that I could hardly bring up a system menu without crashing Explorer. Decided to rebuild the machine and leave out McAffee and a few other of the useless items. System has been ROCK solid ever since. Must have been a bad driver or something. The box now takes everything I throw at it with no problems.

Rebuild it - get it stable then make an image backup. You'll then be set.

HTH,

-Max

Thanks Max, that really inspired me to do a clean install (it's with the Windows 7 CD that came with the laptop guys...I wasn't thinking of formatting the computer in any other way) but what kind of made me scared was greggrocker's post...

Ok dude, let me get this straight...

As far as I'm concerned...Dell is the Windows 7 installer. Therefore, their drivers are what I need...and the drivers on the Dell drivers discs, that came with the laptop, are the rightful ones already on my laptop...as per what the discs say, at least.

And the drivers on their site, for my service tag, are the same exact drivers on the discs.

THESE are the drivers you're saying are beneficial for my Windows 7, right? Meaning, you are not saying, by any chance...that if I do a clean-install of Windows 7 with the Windows 7 CD that came with my laptop, then re-install the drivers given to me via the Dell driver discs, that came with the laptop, or the drivers for that same laptop on Dell's website (which I would get by using my service tag) is a bad idea?

I wasn't planning to format the computer then install drivers for it of my choice. I was getting the ones specicially from the dell driver discs that came with my Inspiron 1545, well actually, I was going to download them from the site. The site tends to have a little more drivers, for some reason.

Even wierd is that, some of these drivers apparently don't even work...Dell told me it's because of my specs. Apparently, you get a service code, but you would have THE SAME service code had you chosen one processor over another, or one graphics card over another...at least, that's why I think some drivers don't work and some do.


By the way Max, how did you rebuild your machine? How did you get the necessary drivers back on it? I guess you have Windows 7 like me. Maybe you can teach me something I don't know...for instance, as I said above, some drivers that come on the Dell drivers discs, apparently don't even work and Dell told me it's because I happened not to choose a certain laptop spec, or something like that, but I could be wrong.

And DUDE, talk about bad OEM installations...you know what? Apparently, a VERY IMPORTANT junction that is NEVER supposed to appear to you, showed up to me even though "hide protected system files (recommended" was checked in my folder options...what kind of a glitch is that?! That caused me to SEE IT, think it was some damn normal folder and mess with it. That screwed up my computer...to the point I couldn't create new user accounts on it anymore. Sersiouly, why do I even make the stupid decidsion to purchase from Dell...

My experience with Dell clean installs and reinstalls of Win7 is to trust the WIn7 installer to provide the correct drivers, try to stay connected via ethernet (the DVD will provide most ethernet and some wireless during booted install) to get current during install, then check optional Windows Updates for newer drivers right after install.

From there, check the Device Manager and only supply drivers which are missing until performance dictates otherwise. The exception is if you get a standard VGA MS display driver which can immediately be swapped out for something more recent from 1) Dell or 2) your graphics card/chip maker's Support Downloads webpage.

In over 100 Win7 installs, I found that if I immediately swap in the maker's chipset driver I often have to roll back to better ones supplied by Win7 installer. So I've instead learned to wait to see if performance requires trying a different chipset, or other driver.

There are others who disagree with this here and think that the old XP rules still apply: have your chipset ready, followed by the standard list order of driver installs. But this completely ignores the fact that MS made a huge decision with Win7 to pay the tab for driver development in partnership with all makers (WHQL program) so that they would have the drivers in the installer or quickly via Windows Updates. This was also so that manufacturers would not hold out on drivers to force new hardware purchases as they did with Vista. I only want to see that MS gets the credit for this, and that unnecessary work is not done due to old habits.

All that said, I am not a Dell owner and have only done about a dozen Dell clean installs (about to do one now when friend here finishes his taxes - for which i am pulling wireless and chipset drivers off Dell website right now just in case) so I will defer to Dell owners for more on this issue.

Wait wait...so you're saying there MAY be drivers currently installed on my laptop that even the maker (Dell) has not included in the Dell driver discs that came with the laptop? If so, what kind of sense is this? The laptop discs even say "drivers that are pre-installed on your laptop"...so why would there be drivers that aren't on the disc as well?

Sorry if I mis-understood your post...it seems you were saying MS payed a company like Dell, to have some drivers pre-configured on their laptops, that Dell doesn't also include IN THE DELL DRIVER DISCS that they send you for free with the laptop you purchase.

 

[gregrocker]

What you seem to be missing here is that there is a huge driver store in the Win7 installer, with drivers for almost every device imaginable. These drivers are current and built for Win7 - some by MS and others by the manufacturers themselves.

My only point is that you don't need to actively change these drivers which are installed with Win7 if there is no performance reason to do so. Just supply any drivers missing in Device Manager, and maybe your display driver if it is more current. The others should work fine and be as good or better than on the dated Dell disk. In fact, I'd work from their website for the most current if any are missing.

I guess every maker has their own. Acer mention on their support site that the updated drivers or current drivers are not provide in Windows 7 pre-install...

Some are already up to date and might have been provided by MS and some are not.

The time they put the computer in the market to sell, there are already updates of the drivers pre-installed...and a new generation of the same line of laptops!

By the way gregrocker, the reason I was contemplating a clean install is, if you look in the "Default Folder" topic in the General Discussion forum, I accidentally fiddled with a junction folder that IS NOT SUPPOSED to show up to you at all. It showed up to me on my new laptop, and after accidentally messing with it, it destroyed by ability to create new user accounts, and I'm going to first to a "start-up repair" to see if that will do anything (not that i think it will) then a repair install which HOPEFULLY will fix the problem (it seems no one knows that it will) and THEN, my last step is a clean install...and this is why I made this topic, to see if a clean install does have benefits.

And one last thing...I am a little confused. Ok, so there are the manufacturer (Dell) drivers on their website which are the most recent, I understand, but can someone answer me this...how come, after inputting me service tag on their website. I am shown some drivers that DO NOT WORK on my laptop? Like I said before, I THINK it's because I don't have certain Dell specs that, If I DID choose them, I would not have a DIFFERENT service tag, so the drivers (that don't work for my specific computer) are there just in case, but this is just my theory. I thought someone perhaps here knew the answer.

Ok, so there are the OEM drivers (Dell drivers) and the MS drivers are VIA windows updates? That thing I do every couple of hours (lol) because if so...then that's awesome.

 

[gregrocker]

Dell has mistakes on their website aplenty. I come across a major one with BIOS updates, drivers, specs, etc. just about every time I do a Dell install.

You can always benefit from a clean install. I suggest you save externally a Win7 backup image of your current install so you can reimage it to the HD in 15 minutes if you want to go back. This way you can use the Win7 installer to format or even deep clean (zero) the HD to have the cleanest possible slate for your fresh install.

 

[Wandering Flame]

I apologize that I still don't know what you mean by "Windows 7 installer"...how does the Windows 7 installer deap clean my HD? Aren't I the only one around who can do that?

And bro, all I'm concerned with right now, is whether or not I am able to gain back all my drivers, and actually ANYTHING back via a clean install from the Windows 7 CD that came with the computer (through, the dell drivers discs OR the drivers on their website, AND windows updates)...that's all I'm concerned with...I keep seeing "Windows 7 installer" mentioned when I've yet to be told what that is exactly, no offense.

 

[gregrocker]

THe installer is the Win7 DVD - we call it "installer" because many are also using USB flash stick to install.

It contains a driverstore with tens of thousands of drivers which are reasonably current, although Windows Updates will deliver newer ones in Optional Updates right after install.

If you have a Dell install DVD then it might be modified somewhat, but should still contain the drivers needed for install. After install check optional Windows Updates for a few rounds, then any drivers which are missing in Device Manager can be supplied from Dell's website or your Driver's disk.

 

[Wandering Flame]

Ok, thanks for clarifying that.

 

[Wandering Flame]

By the way, how do I check if I have startup repair on my hard drive? It's on the Windows 7 CD but I can't find that right now.

 

[Tews]

Boot from your Windows 7 DVD and select repair options...repair install...

 

[Wandering Flame]

The tutorial for the star-up repair here said it may be already pre-installed on my hard drive...the option to do a start up repair...

The disk is what I can't find...the windows 7 disk. That's why I asked how do I check if start up repair is already on my hard drive.

 

[Tews]

Boot computer .. press f8 during install..choose repair computer.... I have never used this option so I cant tell you if it will solve your problem or not... You need to find that disc though!!
