Hi guys. Recently bought a Dell Inspiron N5110. It had windows 7 32-bit installed and I wanted to upgrade to windows 7 64-bit, so I installed it and on the first startup after the whole installation is complete, it flashed a BSOD and restarted, this time it gave me an option to go into recovery mode (or something of the sort) and when I chose that, it again gave me a BSOD with the error that my BIOS is not fully ACPI Compliant. Then i tried to install 7 32 bit instead but that didn't work either. So I installed xp, it installed rather easily but I can't find it;s drivers.

Here are the solutions I've tried

Updated to the latest BIOS

Tried Changing a certain option in BIOS from AHCI to ATA

Read in a forum that removing the battery and draining out the power helps (It didn't)

Someone said they pulled out their 1GB Ram stick and it worked (It didn't)

Someone said installing windows from USB might HELp (It didn't)

So yeah I am completely exhausted have been trying for two days now but can't do anything.

I did however read somewhere that by trying a different CD of WIndows 7 it worked, haven't tried that yet. Should I? Any chance of that working?
Or Should I try Windows 8 instead?

Guys all kinds of input would be appreciated.
Thanks
