bhaveshzzz mate if you run HW Info and let us know what the readouts are - see thus ditty of mine it will soon show up any problems with your PSU (a common problem often overlooked)
UsingHW Info PSU

Download HW Info and pick the right bit version -
HWiNFO, HWiNFO32/64 - Download - (or copy and paste this site into the search bar) If you do not need the running information in the smaller right hand panel close it. In the left hand window click on the + for the individual device groupings and they will open out to the various components.

Go on opening out further until you get to the device itself. click on it and it will highlight. In the right hand window there will be a very detailed description of that device as in brand, speeds model number etc etc These are very detailed and are just what is needed for searching for drivers etc.

To get the PSU volts you need to select the Sensor button circled in yellow in the pic for PSU testing do the same and scroll down the readout as in my pic to where it has Nuvoton = yours might be a different section name / title. Post back apic of that please.

If you want a more definitive test see this
http://www.sevenforums.com/tutorials/301799-psu-test-dc-output-voltage.html
but please only use a digital multimeter and not an analogue as they inject typically 9v into a circuit to test and into a 3.3v or 5v rail - not a good idea!!see the partial pic of the correct sort of meter in that tutorial. details if you scroll down that listing.

Now a good reference article is this
Voltage Rails - Power Supply 101: A Reference Of Specifications it will explain in detail what the voltages are and functions of the PSU and see pic


If you need to send a pic back see this How to Use the Snipping Tool in Vista

Isn't kernel power error related to PSU?

Well it is if you are referring to the Power_Good signal at pin 8 on the 24 pin as the system will not start if the PSU internal check system does not send that signal to the CPU see this

you will find a heap of great info in this article

I don't know if you run any cleaners for the system or on call malware checks but these are worth keeping.

CCleaner - Download < download from piriform will keeps the temp files and rubbish at bay this is the tutorial for it CCleaner - Delete Junk Files just one thing before you run the cleaner make sure to Analyse > Options > Cookies - and any that you use for sites you need passwords for save to the right and liist by highlighting them then click the arrow right. When done go back to Cleaner and run it. (See pic)

Theses are there on call malware scanners I use and a lot of the others use

http://www.superantispyware.com/

http://www.malwarebytes.org/products/malwarebytes_free/

http://www.bleepingcomputer.com/download/adwcleaner/

ADW download frombleeping computer delete any rubbish found with the malware scans
the ADW not so much and you will need to download it each time you run it if you have to.

This is handy too Optimize Windows 7
I am continuing this old thread since replacing the PSU didn't actually solve the issue, instead it complicated the things to worse. After replacing PSU, the whole setup ran fine till March 2015 when the same symptom "no display on cold boots" started once again. The symptom became worse in May 2015 when the system is not booting at all and giving 2 beeps( According to Intel, video card error - reseat the card). This time, even swapping the PSU didn't help. However, I changed my suspicious HD 7750 to an ASUS GTX750 Ti OC 2GB GDDR5 and after that system starts perfectly fine. However, some questions regarding SAPPHIRE HD7750 makes me to investigate the issue that made me to write this thread.
1)The card has no bad capacitors, no broken compoenents
2)The card had no overheating issues and it stayed always less than 63 degree C.
3)This is perhaps the most important point - after all these issues, whenever I put it back to my PC, it won't work( no display,2 beeps). However, if I am lucky, I can get this card working!!!. To me, this is luck or random thing. Out of 10 times putting it back, 3 times it works. If it is working, it can do anything ,even Furmark(recorded max temp - 61 degree C) for couple of hours. But if I shutdown and turn it on after, say 30 minutes, the same issue of no display with2 beeps occur. Ha ha This reminds me of School math - probability, if I am a math teacher, then I could have demonstrated this to students and ask what is the probability of this HD7750 can work in this system?!.
Besides, ASUS GTX 750 Ti works with absolutely no issues . Now my question.
=> Since ASUS GTX 750 Ti OC 2GB comes with a 6 pin PCI-E Connector and hence it draws most of the power directly from PSU rather than motherboard. If that is the case, then there is a possibility that HD 7750 which doesn't require a 6 pin connector is not getting power from the board. I am thinking like this since HD7750 is having no issue, no artifacts if it is working with this mobo. Only way to verify this is to test HD7750 in another motherboard -however, there is no such option for me here. However, my question to you is, if this is true that mobo pci-e is damaged, can this damage the new GTX 750 Ti as well?

Interesting case So the PC ran fine for 9-10 months after PSU change? Don't you have another PCI-e slot to test? Doesn't have to be x16.

Also did you try loading defaults in BIOS (or a CMOS reset), sometimes it helps.

Yes, that's the mysterious thing and it wasn't actually PSU issue at that time! It was either graphics card or mobo.
I don't have another PCI-e slot on this board or I don't have extra PC to test this. However, I will be testing the graphics card on another PC. The issue in that is I asked some of my friends to test this card, but they simply won't believe me and think I will destroy their PC!.
BIOS is loaded with default settings,did a CMOS reset( by taking out the battery for a couple of minutes).
As I have mentioned, the card sometimes work perfectly but now it is purely based on my luck. I am trying to find out the factors which make this card to work on some circumstances. Assuming a capacitor issue ( I am majors in Physics), I did the following things.
1) Faulty capacitor in mobo - I kept on the mobo for couple of hours , so the capacitor is somehow fully charged. Then inserted the graphics card - no luck.
2)Faulty capacitor in graphics card - I kept the graphics card and mobo on ( in the sense PSU is on, but fans,hdd are all off, waiting for the signal to turn on everything). In that situation, current will be flowing through graphics card. However, this also fails.
3) Tried 3 PSUs - 1 350W from Corsair, 550W from Antec and another 550W from Antec.
