I wasn't sure if I should put this under malware or vista...
For a couple months my computer has been extremely slow to do anything 70% of the time, including simple things like open a folder, play an mp3, open control panel, etc. It has occasionally had periods (several days in a row) where it will run really loud for 5 seconds before shutting down and restarting on its own. When it does this it does it consistently every 45 minutes. Then it will go a week or so without doing that all on its own. (I have been good about keeping the vents clean and blowing out the interior).
But last week, sister in law came in from Miss., and used facebook a great deal(that's the only change we can think of), which we've never used, and the computer went nuts. Now it freezes anywhere from 30 seconds to 10 minutes after starting in normal mode. The power button has to be held down to shut it off and then pushed again to start again. It starts and runs fine in safe mode with networking, no problems. But starting up in normal mode now, it consistently has a problem starting either 4 or 5 times in a row, each progressively worse, with windows wanting to do a startup repair on the last one, before finally starting successfully in normal mode, only to freeze shortly thereafter. It will freeze whether we're doing anything or not.
I have Trendmicro antivirus and their help site told me to run Hijackthis which I did and then it suggested posting that log in one of these forums. I've read several posts in several different forums, and don't want to do anything else until you tell me where to start. My suspicions are malware, a posible upgrade from TM, something Vista related, something having to do with addons, or something processor or memory related. But really I don't have a clue.
My computer is a Gateway GM5478 with Vista Home Premium, straight off the shelf from Best Buy 2 years ago. No hardware modifications or upgrades except the additon of one more dvd drive which best buy did before I brought it home the first time.
Intel Core2 Quad processor Q6600, each core 2.4 ghz, 2x4mb L2 cache, 1066 mhz fsb.
Nvidea GEforce 8500gt with 256 mb.
500gb SATA II.
Dual channel 2048mb DDR2.
Vista service pack 2.
32 bit op system.
Under device mgr, the only yellow ! is under system devices, "consumer IR devices".
Any help someone can give would be VERY VERY appreciated! :) Thank you, Joe
