Constant reboots on start up, and monitor black outs??? HELP PLS

[tysond]

I got my computer build a few years ago with parts all purchased separately. Yet ever since I've gotten the PC is has never been a 100% solid machine. The main problem is when I have had the computer powered down say over night, when I go to boot it up in the morning or whenever the PC loads WinXP, then suddenly shuts down again and reboots. This may happen up to two times in a row, and then it always seems to run fine after that. Yet after a few hours sometimes it can just shut down on me without warning. Also every so often even when just browsing the net all applications will seem to freeze yet the mouse will still be able to move, then all of a sudden the monitor will flash black as if it where shut off then come back on and the programs will have resumed whatever they where doing before the "freeze". If anyone that reads this might have an idea of whets going on here it would be greatly appreciated. Also if any further information is needed ask and I will do my best to answer.

Thanks,
Tys

Sounds like classic PSU problems

The reboot problem (especially when on internet) sounds like a virius/worm. Do you have Norton or McAfee installed ? If not I recommend you download one (free trial) and see what it finds. I had a PC with similar symptom and there was spyware in the NIC driver! Of all places. I could not believe it. I also use SPYBOT and AdAware (from

to chekc for nusianceware.
If all this fails, a hardware problem is quite probable.

Hi tyson,

In addition to the others' comments, I'd suggest you check your RAM. We had a computer in our lab that would often spontaneously reboot - once a day at first, then more often, until it was rebooting every 15 minutes. The problem was a bad memory module. Get MemTest (

and run it on your machine. Worth a try, methinks!

Good luck!
