Before i begin let me say thank you to all who volenteer to help us people in need.

I have an HP 750n ... i have upgraded my video card to an eVGA (hope thats enough info?) and havent had a problem until now. It normally runs great.



Ok i have been tinkering with this issue for a few days now, and it is slowly progressively getting worst.

the most obvious issue is that when i open windows media and begin playing a video, the screen begins to flicker, skip and within a few seconds im completely locked up. occasionally the screen even goes black and reads the message "no signal, going to power save"

so it sounds like the video card is overloading at this point ...

But now, im getting the same symptoms without playing any video!! Only seconds after booting it begins to flicker, and eventually it freezes. It appears that opening/manipulating any program speeds up the process of freezing.

Now it sounds like my processor is overloading or something ... but wouldnt that cause a complete shutdown? My PC remains running, even though frozen.

Possible (but in my opinion, not likely) ... 2yrs ago i upgraded my video card to an eVGA card. now while looking into things i see that my pc came with a 4x card, i went for a pretty expensive card so im thinking it was above a 4x ... could it be that this card was too heavyduty for this pc? And if thats the case, why did it run for 2yrs?

So now what do i do? Is there a way to bench test this without investing money?

Is it likely to be a video card? If so, should i just buy a new one? or could it be my processor malfunctioning?

or any other suggestions for how to fix this?

I have gone through msconfig and disabled everything on startup, i have also ran AVG antivirus.

I have tried several times to run a chkdsk but it keeps saying that i cancelled it and it doesnt run.

Welcome to the PCHF rsarno,

First of all it could be a couple of things - first to deal with is overheating.

Open the side of your case, and make sure both your CPU fan and the fan on the Video card is running.

Second, is to make sure you install the latest drivers for your video card. Do you have anymore info on this? The model would help greatly

yeah i used to have a problem like this with my old pc it would crash and restart when watching vids or playing games after weeks of looking for a way to fix it i jst got angry and took the side of it of found that i couldent actuly see the inside of my pc due to dust i clened it up and put the cover back on and the problem was sorted

Overheating: The issue sometimes happens almost immediately after starting the pc. And when the screen freezes, i can still see my mouse cursur moving, but everything else on the screen is frozen.

Drivers: I have the CD that came with my video card, and i reinstalled the drivers. i then asked windows to attempt to update them, but it says i have the most up to date signitures.

I have nothing to base this on, but is it possible im seeing symptoms of faulty RAM? I will think outloud for a moment ...

I began to see the problem only when playing video's .. thats a big load on the memory, so its easy to see why it would cause problems if the RAM was going bad. Then as the problem worstened, it began happening whether i was playing videos or not ... and it seemed to provoke the problem when i went clicking around on the desktop or in the start menu, or anywhere ... which tells me that *something* is at its limit as to how much of a load it can handle ... is it video memory? the card itself? RAM? processor?

any ideas? i hope my info is helping ...

bumpers ...

a little more info ....

the XP login screen offers me either Me or Owner ... if i choose Owner there is barely anything at all running since i never go onto that account. But the problem still happens just the same.

Also, would you believe for the first time i got some error saying "windows has recovered from a severe error ..." and when i clicked for details, it gave me an error code. BUT, before i got to write it or copy it, another stupid error came up on top of it and then my pc froze. what ******* timing!!!

soooo, any new opinions or suggestions?

ALSO, how do i boot into SAFE MODE?!?

more info ...

i went into BIOS setup screen and looked around. it told me that the CPU temperature was 118f (if i remember correctly)

it also gave me the speed of the 2 fans in the pc case .. it all appeared to be normal, but is that temp too high?
