I have a new Acer 5536 laptop i got for about a month. It comes with Win Vista 32bit. I just have Windows 7 64bit installed (clean install, not upgrade). 1) All hardwares are recognized by win7 x64 and all drivers installed automatically by windows. 2) After i've installed the new OS, the system crashes occasionally with the blue screen saying something memory dump and a count down. 3) There's no apparent software causing the issues since there were different softwares running at each occasion. Should I just abandon 64 bit and install win7 32bit instead? i've attached one of the minidump file. Any help would be much appreciated!
