I have been following the "PC Keeps Restarting" thread by "Cozy" closely but have found I have some different issues apart from those reported in that thread.
The computer we're dealing with here is a HP Pavilion a250n, 2.6 GB, Pent 4 with 512 mb of Ram (2 sticks). Win XP HE. It had AVG Virus protection 7.5 Free edition. CPU temp. 105 degrees via the bios.
At the begining it was randomly shuting down and restarting, most often when first starting up but at times later in the day and also sometimes hours later, then again sometimes not shuting down the rest of the day. When I first looked at the PC this 2.6 machine was running about as fast as a AMD 500 socket seven. There were all kinds of programs, games and etc. in start up and a multiude of different programs doing basicly the same thing or trying to (still not running like a 2.6).
Upon running adware detection programs and virus scans we first found several but not high issue infections. We quarinteed and deleted them. Only to find several would return. We deleted them several times and subsiquently figured out those returning appeared to be associated with a free downloaded card game and reappeard when the game was played. The game was deleted and now we no longer have the worms or whatever they are showing up. Still the shut down problem continued but there are no longer any type of virus elements showing up.
After reading the above referenced thread I deleted the AVG program. Shut downs still showed up.
I also went in and set it up so the results of the restart would display the problem as also reflected in the above referenced thread, on the BSOD. Here is the results : PAGE_FAULT_IN_NONPAGED_AREA (looks familiar) along with ***Stop: OXOOOOOO50 (OxE494DOOO, OxOOOOOOOO, Ox804F6719, Ox00000001). This is the same information we get every time.
We no longer have it attached to the internet and a second exact same computer, components and everything is working just fine. Both units, prior to this problem, had been working just fine for some length of time. They are not mine but a neighbors. I do have a different video card I'm about to switch out and see if that works, if that would seem reaonable. I have switched out the Power Supply with a known good, in fact superior one. Same problem.
HP is very limited in their BIOS as to what you can control compared to many, so some of the items suggested in the other thread were not available to deal with. Seeing that some of my numbers are different I was thinking, (hoping) an evaluation by far more experienced website members may give us a quick answer. If not I'll continue on with those being suggested on the referenced thread.
One specific different issue we have, I believe, is that if we are in the "SAFE MODE", it has never crashed or restarted, wouldn't this fact indicate the problem to be software rather than hardware??
