computer won't turn on after new graphic card installed

August 2, 2013 at 19:22:46
Specs: Windows 7
OK so issue started when my BF reset his computer back to factory default. Since then, he was unable to find his graphic card drivers (plus internet issues). He was still able to play games etc on the computer, but was not at desired level. bought a new graphic card tonight, blew air in inside of pc, and installed into computer. turned pc on and pc started then shut off before anything could even load. restarted computer, got high low high low beeps which means motherboard overheating. blew more air inside , tried again, and same results. He has a velocity computer. about 5-6 years old. have to add about a year or so ago he replaced the power supply. I looked at the motherboard hoping something had blown in causing some break in connection but not seeing anything. SO he put back in the old graphics card and still same beeps and same issue. Any suggestions please - does he need to wait for something to cool down enough?

Sounds like he may have dislodged the heatsink. If so it needs to be removed, the old thermal compound removed, and new thermal compound applied.

You told us absolutely nothing regarding system specs or why you went to the extreme of doing a factory reset. A reset should be done as a last resort after all other fixes have been tried. And once a reset it done, a lot of work is required to update Windows, update the drivers, reinstall all your programs, tweak Windows for best performance, etc. It generally takes several hours. The fact that your BF couldn't find something as simple as graphics drivers tells me he's not very adept at this stuff. There are only 3 major graphics providers - AMD/ATI, Intel, & NVIDIA. All he had to do was go to the respective website & download the correct driver, however, he would have to know the exact make/model of the graphics card (or onboard graphics). If he didn't install those drivers, I suspect others are missing as well. Windows generally loads generic drivers to get you going, but specific drivers from the hardware manufacturers should be installed to get best performance from the system. Drivers are required for the motherboard chipset, graphics, audio, network, wireless, bluetooth, etc.

The beeping is a clue to your problem. The number, duration of beeps (short or long), & beep pattern is a code to exactly what the problem is. The fact that it IS beeping is a fair indicator that both the board & CPU are OK, so more than likely the problem is either the RAM was knocked loose or the video card isn't fully seated in its slot. If the card was removed & the beeping continued, the RAM is probably the issue.

Please post the system specs in detail - make/model/model numbers of the board, CPU, RAM, & especially the graphics card & power supply. And when giving the power supply specs, please don't just state the wattage, we need to know the amperage specs on the +3.3v, +5V, & +12v rails. If you don't know, look on the label on the side of the unit.

Velocity Micro computer. AMD motherboard. dual processor Intel, 500GB, 4-512MB DDR2

Power supply:Thermaltake black widow 850W. Specs in the order of max output current, max output power:
+3.3v: 25a, 160W
+5v: 25a, 160w
+12v: 69a, 828w
-12v:0.6a, 7.2w
+5vsb: 3a, 15w

video card: 1GB DR5

Graphics AMD radeon hd 5770

As far as why he set the computer back to factory settings is beyond me and not really the issue as it is already done. I was at work or I would have stopped him!

He just looked at the new graphic that he tried to put in and it requires more ram than he has - could he have fried his ram and could that be what is the issue?

Velocity Micro makes dozens of different computers. At least you provided decent PSU info. 850W is overkill, but at least it's a quality name brand unit so we can probably rule that out as a problem. As for the rest of the specs, AMD doesn't make motherboards. Other manufacturers such as ASUS, Biostar, Gigabyte, MSI, etc make motherboards using AMD chipsets. Also, Intel CPUs don't work with AMD based boards.

And what about the beeps that you mentioned? Like I said in my other response, that is the main clue to the problem. If we knew the make/model of the board & the beep code pattern, we might be able to solve the problem. Different boards use different BIOS types & different BIOS types use different beep codes. Here's the codes for the 3 most commonly used BIOS:



Pheonix BIOS:

"He just looked at the new graphic that he tried to put in and it requires more ram than he has"

Not sure what you mean? The system RAM & the graphics RAM are 2 completely different things, one has nothing to do with the other. When the graphics card is installed, are you connecting the 6-pin PCIe plug to it? It won't work without it.

the beep code is for internal overheating - high pitch/low pitch repeating. There are a total of 4 fans in the system. we ruled out the RAM being the issue based on a conversation with geek squad.

"the beep code is for internal overheating"

Then he must have dislodged the heatsink from the CPU when he installed the graphics card. It will have to be removed, the thermal paste (or pad) will have to be completely removed from the top of the CPU & bottom of the heatsink, then fresh paste must be applied & applied correctly. You're making this very difficult by not listing the specs. Different CPUs require different application methods. Find your CPU using the following link, then follow the instructions exactly. You don't have to use Arctic Silver, any brand will do.
