Answer» My computer has no video image on the LCD. I tested the LCD on another computer and the LCD is fine. I put another known working LCD on the computer in question and still no image on the LCD. The computer has inter-grated graphics and has a blue VGA connector. It is a Compaq Presario SR2050NX. The motherboard has these series of numbers on it: RC410-M Rev 1.1 and this serial number Q1115033F69S112F. I looked it up on-line (or at least I think I found it on-line) and some websites says it’s a Asterope???!!!. Don't know if mine is the Asterope(?!?) The online description does SAY that the motherboard supports a PCI-E X16 graphics card via one PCI - Express slot, which the motherboard does in fact have.
I picked up a video card which is a PNY Ge-Force GT 430 video card. I told the salesman what I needed (a x16 graphics card) and he said this is what I needed. I put the video card in the PCI-E slot turned on the PC and still no image on the screen. I picked up some new RAM an installed it and still no image. I TOOK out the video card and installed the LCD to on inter-grated VGA connector and left in the new RAM and still no image! At this point I am thinking the motherboard is bad. But if the motherboard was bad wouldn't I see some expanded capacitors?!?
Thanks for all the help!!!! This is the same computer as in your other thread?
If you see bulging capacitors on a motherboard, that's often sign that it's faulty or potentially unreliable but that does not mean that all faulty or dead motherboards will have them, there are plenty of other things that could fail that leave no visible signs. Also have you considered the PSU (power supply unit)?
In fact I think the fact that there is no display on the monitor is misleading you into thinking that you have a video problem. What you have in fact is a dead computer. This could be a failed motherboard or possibly the power supply. What you need to do is a complete TROUBLESHOOT. Use your eyes and ears. When you connect it to the AC and push the power button, do you hear anything like FANS, hard drive, etc, or is it silent? Is the power cord properly inserted at both ends? Are there any lights lit on the motherboard? If there is a switch on the PSU is it in the correct position? If there is a 120v/240v switch, likewise? (Don't flip this with the AC connected!) Next visually confirm all internal cables are connected nicely. Try wiring a different power button to the header on the board. If you have a spare known good PSU of adequate power rating swap it in. Try running the PC with the disk drives disconnected and only 1 stick of RAM. If all of these fail then possibly the motherboard has failed.When I plug in the PC to the wall outlet I do see a green lite on the back of the PSU the portion that is visible on the outside of the PC case. All internal connectors are correct and the CPU fan and case fan stay on for a long period of time. I tried switching the RAM like you recommended but still no image on the screen?!? However when I turn the PC on I dont hear any kind of beeping sounds. But I touch the harddrive and it does appear to be on. I put my hand on it and can feel the insides moving. At this point I really think its the motherboard the went bad...........................any ideas where i can get one of this type for cheap. I found some online that I think they are the same, but they cost anywhere from $65.00 to $80.00 Ouch !!??!!

One last thing to inspect though is the processor. Maybe try to clean and reapply some thermal paste and make sure its well seated with heat sink.The heat sink and CPU look just fine.............................I think it's the Motherboard ??!!??Here are the specs of your motherboard: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00783614&tmp_task=prodinfoCategory&cc=us&dlc=en&lc=en&product=3245052#N50 No beeps at all? Just blank screen? As a last ditch effort you may want to try resetting CMOS: My guess is also that the motherboard is damaged. I tried the CMOS thing but still nothing........I am gonna shop around for a used Mobo.......any ideas where to get a good price....??
Thanks everyone for you input.......I WIL keep u posted !!!!You don't have to get the exact same motherboard for a replacement, you can pop another motherboard with the same chipset as yours (which is the ATI Radeon Xpress 200 for Intel Processors, BTW), and it'll work without problems. http://www.amazon.com/RC410L-ECS-RC410L-800-M-64BIT-Graphic/dp/B000VCTGQQ/ref=sr_1_2?ie=UTF8&qid=1336272083&sr=8-2 A replacement motherboard for example.
