The monitor is not fibbing to you BTW, the PC did go dead or to sleep. seems its monitor monitor of some kind with DVI.

if the monitor works on other PCs then the monitor is not bad.
i Bet it works (old ones 2002, have a hidden deep internal sleep mode. and is not yours IM sure now) DVI IS THE ONLY CLUE THERE.
So PC is dead. this PC came with only VISTA new,
is it still VISTA?????????
HP has support on it still
here (carbon dated by me 2008, IIRC)
https://support.hp.com/us-en/drivers/selfservice/hp-pavilion-slimline-s3400-desktop-pc-series/3688715/model/3688723

this year,? get all those files and books there backed up
when HP support ends after 10 year rule, (be savvy?)


what keyboard USB or wireless keyboard mouse
use wired USB keyboards if wireless the battery is dead. easy no?

now in VISTA, go to Control panel, click power
turn off all sleep modes and all hibernate modes
the turn off screen savers, if turned on , disktop . RC right click
in display settings or personalize, turn off , need login to come out of sleep or screen saver.
try a real keyboard, that has USB cable yet? be first thing to do.
always keep a real keyboard, handy,,,
batteries fail. in all wireless devices like this (inside them)

Click the Windows "Start" button or press the "Windows" key. The "Start" menu opens.

Type "Cursor blink" in the "Search programs and file" text box.

A list opens.

Click "Change Cursor Blink Rate." The "Keyboard Properties" window opens.

Click the "Speed" tab. A list of options appears.

The "Cursor Blink Rate" section shows a "Cursor Blink Rate" slider displaying a range from "None" to "Fast."

Click and drag the slider button to the "None" area in the far left portion of the "Cursor Blink Rate" scale.

Click "Apply."

Click "OK." The cursor stops flickering on the screen.

hope this helps

what type of mouse is it? If it's a wireless optical mouse replace the batteries or throw it away, i prefer the latter

Dynex is a cheapo brand that usually can be found at Bestbuy. I would not recommend the dynex products at all. You could be getting interference from cell phones, your monitor, a microwave oven, etc.. I have a couple wireless mouse and keyboard sets I got at radioshack that work very well. They only cost me about 20$ and are the Labtec brand.

If you want something a lot better go for logitech products, they are a bit more pricey though.

If you do not move the mouse or press any key on the keyboard it could be just going into video power save. Confirm it by moving the mouse or pressing a key on the keyboard. If the monitor comes back on, adjust the power settings in control panel and change the time for the "turn off display" to a more suitable setting.

1.try to change a screen resolution on your monitor. if did not solve your problem
2.change the colour quality either 32 bit or 16 bit

try your best.

please rate this solution whenever.

well there is a few things that could possibly be happening. if it is a touch pad or a wireless mouse something like a cell phone sitting close enough to them could be causing some interference. the second one is that you could possibly have the mouse keys turned on where you can control the mouse with the keyboard.

I'm not much of help being 13 but jiggling the mouse? ._.

The issue may not necessarily be with the mouse. Are you able to use the keyboard once the mouse freezes? If you not even able to use the keyboard, there is some application installed on your computer or a virus due to which the mouse freezes. If, in case, the keyboard works even though the mouse is stuck, try changing the USB port or try a different mouse. Please revert back with any other observations. Good Luck
