I have an
HP OMNI 120 All-in-One PC Series
Product No. OW800 AA#ABA
Model No. 120-1125
Windows 7 Home Premium OA
I dont know if it is 32 or 64 bit... I could not find that info.
I bought it second hand from a computer shop, everything was fine except when I tried to log in to my school web site, Liberty University it took forever, and a couple times I couldn't log on. So I called them, they said bring it back they needed to change the memory. They delivered it back to me today (yesterday now) i hooked everything up the lights in back where you plug in the cord and the ethernet cable came on. I can feel it running but a big blank screen...hoping for a simple solution i can do myself.....I guess everyone is 
Everything else logged on fine facebook, gmail ..etc...
Thank you
Monica Boothe
