My computer (Compaq Presario CQ61) feels like its just about to give up the ghost, but its only a year old. I'm running Windows 7 Home Edition on it.
I've run a memtest86+ test on it and it hasn't detected any errors. There's no blue screens, or sudden system crashes, the browser just hangs whenever a page with more than medium size content is delivered.
My desktop apps don't seem to be running any slower than normal as far as I can tell.
I run AVG antivirus and it hasn't detected anything after daily scans.
Important point to note, the battery has gone because it only lasts about 10 minutes without being plugged in. I don't see how that would specifically affect browser performance, though.
What can I do to solve this?
