computer acting weird with new bios upgrade

[allen1979]

hi all. i just got some help here yesterday, so i was hoping to get some today as well. i just upgraded my bios yesterday, and now my computer reads all of my ram! yay! bad news is, now things are acting kinda weird. when i first turn on the computer, is starts fine. comes to the desktop screen fine. but then it kinda freezes for about two minutes. can't do anything except open the task manager and play with the mouse. it won't even connect to the internet. then when everything starts working again, it takes like 2 minutes-literaly for ANY web page to appear. i have checked with internet company twice, and both times they say there is no problem with the internet connection.

any ideas???
any help would be greatly appreciated!

ps- about one out of ten times of restarting, things actually work the way they are supposed to, not sure if that help

Run Dell Diagnostics from hotkey given at boot.

I'd work through these Troubleshooting Steps for Windows 7 - Windows 7 Forums

Fill in your System Specs. For less than 4gb RAM I'd be running 32 bit Win7.

If the problem can't be resolved I'd consider getting a superior Clean Reinstall - Factory OEM Windows 7
