A few days ago I came down with a rather unpleasant flu that lasted two days. I believe my flu virus got into my computer and digitized itself because ever since I got up the morning I was sick my computer's been acting strange.
It all started last Friday. I sat down on my computer and decided to put on Netflix while I attempted to eat some soup. As soon as I started Firefox, the system shut off. Just went dead. No shutdown, no errors, just off... mostly. The power light was still on. After turning it off completely, it would not start up. It would begin startup then just power off. So I inspected connections, cleaned it out. Nothing seemed wrong. I couldn't find any evidence of overheating (which I've never had a problem with anyway.) After about 15 minutes I was able to start the computer and it started up as if nothing happened. I didn't find anything wrong in my inspection. I've had no random shutdowns since then.
After that, the system fans have been acting rather odd. The rear fan has started running faster than normal as if the system is heavily processing something, even when sitting idle. I have software to monitor fan speeds, temperature, etc. System temperatures are normal. Everything is in the green and the CPU usage is low.
The monitor also indicates that the front fan's speed is randomly fluctuating between about 400 RPM and 200,000+ RPM. Which I very much doubt since from what I observe it's running pretty steadily and normal. (This one I'm least worried about.)
Last night, before bed, I put the computer to sleep (Hibernate mode) and it powered off. I woke up this morning and it was on. However, all I had was my desktop. No icons, no windows, no logon, just my desktop and the cursor. Control + Alt + Delete didn't bring up anything so I ended up hitting the reset switch.
I normally put the computer to sleep (hibernate) when I know it'll be idle for long periods of time, like when I go to bed at night or when I go to work for 9 hours.
System info: Pentium 4, 3 GHz. Windows XP Professional SP3. 2 GB of RAM.
