No input signal on monitor after changing resolution
Hi all, just today I was upgrading a compaq desktop 2.4Ghz pentium 4. I put in a 1Tb hard drive and tv tuner and also a video card which didnt help, so I went back and put in the original which was in the PC. Everything was fine I installed windows and in a happy moment I changed the screen resolution to some high value and it was working fine and the problem started when I shut down and restarted again. There is no input signal to the monitor even though the cpu seems to be working fine.I tried changing the video card the hard drive itself( with a 40gig), the monitor , connected the cable to another input source on the cpu and almost everything. But to no avail. PLease Help!!!!:-(

This pc would not benefit from a CPU upgrade. You could buy a used pc much more powerfull than this one from sites like Ebay for about £50 or so.
You would need more memory, older memory is now very expensive.
So it would cost more money to upgrade this pc than it would to buy a replacement.

Hi, mine was running slow too. Like I'd turn it on and go grub some coffee, than make some toast and then after It'd bring the windows screen on. If that's the case I suggest to try different hard drive, but my guess it's motherboard issue: Here is memory information for EVO D51. Please let me know what model you have, so I can be more specific
