Windows 7: I need help for a weird problem.

Hey guys, real sorry in advance if this has been all explained in another thread :$

Here's what happened :

I went from Vista to 7 home premium without any trouble and installed my usual programs. Then my computer started crashing with some IRQL less or equal BSOD errors while I was downloading files (>3mbps). The problem persisted (but had no effect at all on speed during startup) and I grew a bit tired of it so I chose to follow the system's advice to troubleshoot the startup. Since then, my computer started taking over 15 minutes to boot and even though I scrolled countless threads, I managed to fail resolving the problem. Then I though that I maybe had messed up something in the OS so I reinstalled, making sure that I had formatted everything. The problem is that the startup is stil WAY slower than what it used to be : from a startup time of 45s before the troubleshoot (when i went from vista to 7) to around 4minutes. I tried starting with minimal settings and it still takes over 2 minutes...
Just in case it can give an insight to anyone, the startup lags at the "windows starting (with the pulsing flag) and then right after I put my PW in to log.

ESET's system inspector tells me that my drivers are fine and my windows index is still the same at 4.6. Windows troubleshoots detect no problem whatsoever.

All in all, I just don't get what's wrong with my lappy, so I'm asking for help !

Thanks all in advance

Welcome to Sevenforums,

You might want to have a look at your Mfg Computer Site, looking for proper drivers side by side with the one windows 7 installed. Could be a bios update to do also, from the Vista one to Windows 7 one..

On the slim chance do you have a backup from before the problem that we can restore from? do you have a working win 7 dvd to do a repair install?

Welcome to SevenForums.

do a System Restore from a point BEFORE the problem appeared.

WIN + F1 | type System Restore | Enter key

WIN is that key with wavy flag on it.

"WIN + F1" huh?

yep,
Win + F1 key combo gets you Windows Help.

This gives that one and a few more.

WIN + F1 brings up Help and Support on my machine.

You make everything so hard when there are excellent tutorials here to link.


How to Do a System Restore in Windows 7

I did try to do a restore to a version prior to the bug, and it worked (the restore), but the startup speed still was crappy... I already did the winkey + f1 and there's nothing i could find there.

I'm making sure sure that all my drivers are up to date and I'll read those links you guys gave

thanks so much for the lightning fast answers
